The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terminal described in the embodiment of the present invention may include: a mobile phone, a tablet computer, a notebook computer, a digital camera, a digital video camera, and the like. The above terminals are only examples, not exhaustive. The method for generating a terminal input signal and the terminal provided by the embodiment of the present invention will be specifically described below by taking a mobile phone as an example.

FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for generating a terminal input signal according to an embodiment of the present invention. It can include the steps of:

S101. Acquire a tap signal on the first operating platform.

In a specific implementation, the first operating platform described in this embodiment may include: a terminal body, a surface of a flat object on which the terminal is placed, an input device of the terminal, and the like. For example, the first operating platform described in this embodiment may be The phone itself, or the horizontal desktop, ground, mobile phone input keyboard drawings, user-defined input drawings, etc. When the user wants to generate a terminal input signal, he can tap on the mobile phone (including the back of the mobile phone or other parts of the mobile phone) or the desktop of the mobile phone, and the mobile phone can obtain the mobile phone or place the mobile phone through its built-in sensor. A tap signal on the desktop to generate an input signal of the mobile phone based on the tap signal. The tapping signal on the first operating platform may include: a vibration mechanical wave, a tapping time, a tapping intensity, and the like. For example, when a mobile phone user plays the game using the piano in the mobile application, if the mobile phone is required to generate an input signal of the piano playing game according to the tap signal, the mobile phone function can be turned on before the game is played, that is, according to the first operation. on the platform The tapping signal generates a phone function that the piano plays the input signal of the game. After the mobile phone user activates the above mobile phone function, the tapping action of playing music can be performed on the back of the mobile phone or on the desktop where the mobile phone is placed, and the mobile phone obtains the tapping signal on the back of the mobile phone or the desktop of the mobile phone through the built-in sensor. , the input signal of the mobile phone piano playing can be generated according to the tapping signal. The mobile phone user does not need to input the playing signal through the virtual keyboard of the piano playing the game, and only needs to perform the tapping action of the playing music on the first operating platform to complete the signal input of the piano playing.

In the specific implementation, in order to prevent the mobile phone from randomly generating a mobile phone input signal according to the tapping signal on the mobile phone or the desktop of the mobile phone, affecting the normal use of the mobile phone, a startup mode of starting the function of generating the mobile phone input signal of the mobile phone may be set. When the mobile phone user wants to activate the mobile phone function (that is, the mobile phone function for generating the mobile phone input signal according to the tap signal), the tapping action can be performed at the designated position on the first operating platform, and the mobile phone obtains the tapping signal at the specified position. This phone function can then be activated. For example, in order to prevent the mobile phone from randomly generating an input signal of the piano playing game of the mobile phone according to the tapping signal on the mobile phone or the desktop of the mobile phone, the mobile phone user can perform corresponding knocking on the designated position of the mobile phone when starting to play the music. The action of the mobile phone is used to activate the function of the mobile phone. The function of the mobile phone is a function of generating an input signal of a piano playing game of the mobile phone according to the tapping signal, and the built-in sensor of the mobile phone can obtain the tapping signal at the designated position of the mobile phone. Start this phone function yourself. For example, when a mobile phone user plays the game on the piano in the application using the mobile phone, he can first tap on the top left corner, the upper right corner, the lower right corner, and the lower left corner of the mobile phone to start playing, and the mobile phone obtains the above mobile phone. After the tap signal in the position, the corresponding mobile phone function can be activated (ie, the function of starting the input signal of the piano to generate the piano playing according to the tapping signal); when the mobile phone user wants to end the game, the mobile phone can be in the lower left corner of the mobile phone. In the lower right corner, the upper right corner, and the upper left corner, each taps to indicate the end of the play. After the mobile phone obtains the tapping signal at the above position, the mobile game application server can be turned off by itself, and the piano playing is no longer received. input signal. In addition, hand The user can also tap on the top, bottom, left, and right sides of the phone to start playing, and tap on the right, left, bottom, and top of the phone to end the play. The manner in which the above actions are started and ended is only an example, not an exhaustive one.

S102. Determine a tapping point position of the tap signal on the first operating platform.

After the mobile phone obtains the tapping signal on the first operating platform through the built-in sensor, the tapping point of the tapping signal on the first operating platform may be determined according to the tapping signal. Specifically, a positioning coordinate system of a mobile phone may be set with a specific point on the mobile phone (for example, the center of gravity of the mobile phone) as a coordinate origin, and the mobile phone may be set in a plane where the mobile phone display screen is located or a plane where the mobile phone back cover is located. Positioning the coordinate system, the direction of the bottom edge of the mobile phone is the X axis, and the direction of the side of the mobile phone is the y axis, which is used to determine the tapping point position of the tapping signal on the operating platform such as the mobile phone or the desktop on which the mobile phone is placed. Specifically, the coordinate axis of the positioning coordinate system of the mobile phone may be preset in advance for the coordinate origin of the specific point on the mobile phone, and the position of each sensor in the mobile phone in the positioning coordinate system is determined according to the positioning coordinate system, for example, as shown in FIG. 2 . Shown. After determining the positioning coordinate system of the mobile phone, the position of the sensor 1, the sensor 2, the sensor 3, and the sensor 4 in the positioning coordinate system is determined to be (xl, yl), (x2, y2) according to the positioning coordinate system of the mobile phone. ( x 3 , y3 ) , ( x4 , y4 ) , wherein, since the position of the built-in sensor of the mobile phone relative to the mobile phone is a fixed position, the positions of the above-mentioned respective sensors in the positioning coordinate system are all determined positions, that is, xl, yl , x2, y2, x3, y3, x4, y4 are all known numbers. After determining the position of the built-in sensor 1, sensor 2, sensor 3, and sensor 4 of the mobile phone, when the mobile phone user taps on the tapping point (X, y) on the first operating platform at time t, the vibration mechanical wave is generated and directed After being spread around, the mobile phone can receive the vibration mechanical wave of the tap signal according to each sensor at time t1 (the time of the vibration mechanical wave received by the sensor 1), t 2 (the time of the vibration mechanical wave received by the sensor 2), t 3 (sensor 3) The time of the received vibrational mechanical wave), t 4 (the time of the vibration mechanical wave received by the sensor 4), and the time at which the tapping signal is generated, that is, the tapping time t of the tapping signal and the propagation velocity V of the vibrating mechanical wave, calculate each of the mobile phones Sensor The distance from the tapping point position of the tap signal. When calculating the distance between each sensor and the tapping point position of the tapping signal, the mobile phone can combine the position coordinates of each sensor in the mobile phone in the positioning coordinate system, and multiply the propagation speed of the vibration mechanical wave by the time equal to the propagation distance of the vibration mechanical wave ( That is, the distance between the position of the tapping point and each sensor is processed. The distance between each sensor and the position of the striking point is obtained, the propagation speed of the vibrating mechanical wave of the striking signal, the time point when the sensor receives the vibrating mechanical wave, and the tapping time of the tapping signal. The relationship equation is as follows: 4 yuan 2 equations:

- yf - t) xv

- 2 + O - yf - t) xv

Since v, t, x, and y are unknowns in the above data, you can process v, t, x, and y by a preset value, and by iterative calculation, you can know that _v , t, x, and y are four. The value of the unknown number determines the tapping point position (X, y) of the tapping signal on the first operating platform.

In the specific implementation, since the propagation speed of the vibration mechanical wave in the specific medium is fixed, and the medium used for the mobile phone case is fixed and known (because the material of the mobile phone case is determined by the mobile phone, the mobile phone case is used for the mobile phone case) The medium is also known to be identifiable. The propagation speed of the vibrating mechanical wave on the casing of the mobile phone is also fixed and can be stored in advance in the mobile phone. When the mobile phone user makes a tapping action on the mobile phone (ie, the mobile phone casing), the propagation velocity V of the vibration mechanical wave generated by the tapping on the mobile phone becomes a known amount, and the calculation of the above-mentioned 4 yuan equation 1 is performed. During processing, the propagation velocity V can be treated as a known number. When the tapping point is on the mobile phone, the position of the tapping point of the tapping signal on the mobile phone in the positioning coordinate system (X, y) can be processed by the three sensors. If there are the above four sensors, the calculation accuracy of the position of the tapping point can be estimated according to the least squares method. In this embodiment, at least three sensors for acquiring the tapping signal are required, at most, not limited. As shown in Figure 3, if the tapping signal is outside the mobile phone, that is, when the first operating platform is a platform such as a desktop on which the mobile phone is placed, since the material of the desktop may be of various types (such as wood, plastic, iron, etc.), The propagation medium of the vibration mechanical wave of the hitting signal becomes an unfixed medium, and the mobile phone cannot predetermine the propagation velocity V of the vibration mechanical wave of the tapping signal on the desktop currently placed on the mobile phone, that is, the propagation velocity V of the vibration mechanical wave at this time is unknown. When the tapping point of the tapping signal is on the platform such as the desktop on which the mobile phone is placed, the values of the four unknowns of v, t, x, and y can be determined according to the data acquired by the four sensors of the mobile phone, thereby determining the tapping signal. The location of the tap point on the first operating platform. The mobile phone judges, according to the data obtained by the above sensor, the speed of the vibration mechanical wave on the current propagation medium (ie, the desktop on which the mobile phone is placed), when the mobile phone user taps the second time on the same medium, that is, the mobile phone user places the mobile phone. When tapping the second time on the desktop, since the propagation velocity V of the vibrating mechanical wave has been determined, the calculation of the tapping point position of the tapping signal on the first operating platform can be initially estimated based on the data acquired by the above four sensors. Precision. Specifically, the mobile phone user can obtain the 4-element second-order equation corresponding to the tapping signal of the second tap according to the above method, and can determine the propagation velocity v of the vibrating mechanical wave (ie, the vibrating mechanical wave) in the first tapping. The propagation speed on the desktop where the mobile phone is placed) is substituted into the above 4-ary equation 2, and then combined with any three of the equations to obtain the tapping signal of the second tap on the first operating platform. Is the coordinates (xl, yl) in the phone coordinate system. In addition, the user can directly obtain the tapping point position 2 of the tapping signal of the second tap on the first operating platform according to the above 4-ary equation 2 (assuming coordinates (x2, y2) in the mobile coordinate system. ), and according to the position 1 of the tapping point obtained in the previous processing, it is judged whether the coordinates of the tapping point position 2 (x2, y2) and the tapping point position 1 (xl, yl) coincide or whether the error is within the set error range, In this way, the calculation accuracy of the tapping point position of the tap signal on the first operating platform is estimated.

S103. Map a tapping point position of the tap signal on the first operating platform to an operating position on the second operating platform. S 1 04 , using the tapping signal as a trigger signal on an operation position on the second operating platform, and generating a terminal input signal corresponding to the trigger signal for the terminal.

In a specific implementation, the second operating platform is an input platform of an application input interface of the terminal, a character input soft keyboard of the terminal, and the like. For example, the virtual keyboard of the piano playing game in the application on the mobile phone, the character input soft keyboard of the mobile phone input method, the shooting button on the photographing function interface of the mobile phone, and the like. The above operation buttons are only examples, not exhaustive. The operation position on the second operating platform may be: a key value of an input button of the application of the terminal, a key value of a character input soft keyboard of the terminal, a touch position on a touch screen of the terminal, etc., for example, an application on the mobile phone The key value of the piano playing game in the program, the key value of the character input keyboard of the mobile phone input method, the key value of the shooting button of the camera function of the mobile phone, the touch coordinates on the touch screen of the mobile phone, and the like.

After the mobile phone determines that the tapping point position of the tapping signal on the first operating platform is known, the position of the tapping point of the tapping signal on the first operating platform in the positioning coordinate system of the mobile phone and the pre-stored positioning may be The database is matched, and the operation position on the second operating platform of the mobile phone corresponding to the tapping point position of the tapping signal on the first operating platform is determined by database matching, and the tapping signal is tapped on the first operating platform. The hit location is mapped to the operational location on the second operating platform of the handset. In a specific implementation, a perceptible tapping area of the mobile phone may be set in advance by using the positioning coordinate system of the mobile phone as a reference system. For example, a side length of the mobile phone positioning coordinate system may be set to be 2× long. Width 2Y (where the specific values of X and Y can be set at the same time as setting the positioning coordinate system of the mobile phone, or can be customized by the user of the mobile phone), the square area of the mobile phone is the perceptible area of the mobile phone, and the above-mentioned perceptible is set. The operation position on the second operating platform of the mobile phone corresponding to each tapping position in the area (specifically, the key value of the button on the second operating platform of the mobile phone, etc.), and all the corresponding relationships are stored in the mobile phone positioning database. When the mobile phone user places the mobile phone smoothly and determines the first operating platform of the mobile phone (such as the mobile phone body or the desktop on which the mobile phone is placed), the mobile phone can determine the current first according to its positioning coordinate system. A perceptible area on the operating platform (such as a specific area on the phone body or a specific area on the desktop where the phone is placed). When the mobile phone user performs a tapping action within the perceptible area of the first operating platform, the mobile phone can position the tapping point of the tapping signal on the first operating platform in the positioning coordinate system and the pre-stored positioning. The database performs matching to determine an operation position on the second operating platform corresponding to the position of the tap point on the current first operating platform. For example, in the scenario shown in FIG. 2, after the mobile phone user makes a tapping action on the back of the mobile phone, the mobile phone determines that the tapping point position of the tapping signal on the mobile phone can be matched through the built-in positioning database of the mobile phone. Mapping the location of the tapping point of the tap signal on the current mobile phone to the key value of the key on the piano playing game of the corresponding mobile phone, and then using the tapping signal as a trigger signal on the key to generate a corresponding The input signal of the piano playing game that triggers the signal. For example, as shown in FIG. 4, when the mobile phone determines that the tapping point of the tapping signal on the back of the mobile phone is a point on the upper left corner of the back of the mobile phone (such as the tapping point shown in FIG. 4), The built-in positioning database of the mobile phone matches that the current hitting point position corresponds to the virtual key on the mobile phone's piano playing game, and the third key from the left of the keyboard (ie, the key corresponding to the mapping point in FIG. 4) , you can map the tapping point on the back of the phone to the key of the phone's piano playing game. Similarly, when the tapping point of the tapping signal is at other positions on the back of the mobile phone, it can also be matched by the built-in positioning database of the mobile phone, and it is judged that the tapping point position of the tapping signal corresponds to the key of the button on the virtual key. value. After the mobile phone determines that the key value of the specific key of the virtual keyboard of the piano playing game of the mobile phone corresponding to the tapping point position of the tapping signal is known, the mobile phone can use the tapping signal as a trigger signal of the key value, and the knocking The signal is used to trigger the built-in virtual piano application of the mobile phone, and the music playing manager of the mobile phone is called by the built-in virtual piano application of the mobile phone to play the music corresponding to the tapping signal. That is, the mobile phone can map the tapping point position of the tapping signal to the key value of the button on the virtual piano application on the mobile phone, and convert the tapping signal into a trigger signal of the button on the virtual piano application of the mobile phone, through the virtual state of the mobile phone. The piano application calls the music playback manager to emit a tone corresponding to the button Corresponding tonal sound, and adjusting the music of the volume corresponding to the tapping intensity according to the tapping intensity of the tapping signal, that is, the mobile phone can emit different tones at different volume according to the tapping position of the mobile phone user and the tapping intensity music. The user can adjust the tone and volume of the music emitted by the mobile phone according to his own tapping action, better mobilize the interest and passion of the mobile phone user to play music through the mobile phone, and also trigger the inspiration of the music creation of the mobile phone user, and improve the signal input. Interesting.

In this embodiment, the location of the tapping point of the tapping signal on the operating platform such as the desktop of the mobile phone or the mobile phone is mapped to the operating position on the second operating platform of the mobile phone, and the tapping signal is used as the operating position. The trigger signal is used to trigger the internal application of the mobile phone, generate a mobile phone input signal corresponding to the trigger signal, expand the generation path of the input signal of the mobile phone, improve the interest of generating the input signal of the mobile phone, and improve the user experience of the mobile phone. .

FIG. 5 is a schematic flowchart of a second embodiment of generating a terminal input signal according to an embodiment of the present invention. It can include the steps of:

5201: Obtain a tap signal on a calibration point on the terminal input device, and determine a position of the calibration point on the terminal input device in the positioning coordinate system of the terminal.

S202: Determine a relative position of the terminal input device and the terminal according to a position of the calibration point in a positioning coordinate system of the terminal, and a position of the calibration point on the terminal input device.

In a specific implementation, the first operating platform described in this embodiment may include: a terminal body, a surface of a flat object on which the terminal is placed, a terminal input device, and the like. For example, the first operating platform described in this embodiment may be the mobile phone itself, or a desktop on which the mobile phone is placed, or a mobile phone input keyboard drawing printed by the mobile phone user and placed on the desktop of the mobile phone together with the mobile phone (for example, in FIG. 6 The keyboard diagram shown, or the user-defined input drawing (such as the auxiliary drawing shown in Figure 7) printed by the mobile phone user and placed on the desktop of the mobile phone together with the mobile phone. Wherein, the above mobile phone input keyboard drawing or mobile phone user customized input The input drawing or the like is the terminal input device in the first operating platform described in this embodiment. In the specific implementation, the input keyboard drawing of the above mobile phone and the input drawing of the user defined by the mobile phone are a special type of paper, and the paper includes information such as an input keyboard picture.

When the user wants the mobile phone to generate the terminal input signal according to the tapping signal, the input keyboard drawing of the mobile phone or the user-defined input drawing of the mobile phone can be smoothly placed on the desktop where the mobile phone is placed (ie, the desktop where the mobile phone is located), and the keyboard drawing or The mobile phone user can make a tapping action on the input drawing of the mobile phone, and the mobile phone can obtain the input keyboard drawing of the mobile phone or the tapping signal on the input drawing of the mobile phone user through the tapping signal acquisition module such as the built-in sensor, etc., according to the knocking The input signal of the signal generating terminal is clicked. The tapping signal on the first operating platform may include: a vibration mechanical wave, a tapping time, a tapping intensity, and the like. For example, when a mobile phone user uses a mobile phone's input keyboard drawing to input a mobile phone character, if the mobile phone is required to generate a character input signal according to the tap signal, the mobile phone function may be first turned on, that is, according to the first operating platform (ie, the input keyboard drawing of the mobile phone). The tapping signal on the phone generates a character input signal for the phone function. After the mobile phone user activates the above mobile phone function, a tapping action can be performed on the input keyboard drawing of the mobile phone, and after the mobile phone obtains the tapping signal on the input keyboard drawing of the mobile phone through the built-in sensor, the mobile phone input can be generated according to the tapping signal. The input signal of the law. In a specific implementation, the mobile phone obtains a tapping signal on the input keyboard drawing (terminal input device) of the mobile phone through its built-in sensor, and before inputting the input signal of the mobile phone input method according to the tapping signal, it is also necessary to confirm the input keyboard drawing of the mobile phone first. The relative position with the mobile phone, that is, the transformation relationship between the positioning coordinate system of the input keyboard drawing of the mobile phone and the positioning coordinate system of the mobile phone needs to be determined. Specifically, the mobile phone user needs to tap the calibration point on the input keyboard drawing of the mobile phone to calibrate the relative position of the input keyboard image of the mobile phone and the mobile phone.

After the mobile phone obtains the tapping signal on the first operating platform through the built-in sensor, the tapping point of the tapping signal on the first operating platform may be determined according to the tapping signal. Specifically, a specific point on the mobile phone (for example, the center of gravity of the mobile phone) may be used as the coordinate origin. Positioning coordinate system of the mobile phone, set the positioning coordinate system of the mobile phone in the plane where the mobile phone display screen is located or the plane where the mobile phone back cover is located, with the bottom direction of the mobile phone being the X axis, and the direction of the mobile phone side being the y axis, The position of the tapping point of the tapping signal on the operating platform such as the mobile phone or the desktop on which the mobile phone is placed (ie, the position of the tapping signal in the positioning coordinate system of the mobile phone). Specifically, a specific point on the mobile phone (for example, the center of gravity of the mobile phone) may be used to preset a coordinate axis of the positioning coordinate system for the coordinate origin, and according to the positioning coordinate system, determine the position of each sensor in the mobile phone in the positioning coordinate system, such as figure 2. After determining the positioning coordinate system of the mobile phone, the position coordinates of the sensor 1, the sensor 2, the sensor 3, and the sensor 4 in the positioning coordinate system are determined according to the positioning coordinate system of the mobile phone as (xl, yl), (x2, y2). (x 3 , y3 ) , (x4 , y4 ) , wherein, since the position of the built-in sensor of the mobile phone relative to the mobile phone is a fixed position, the positions of the above-mentioned respective sensors in the positioning coordinate system are all determined positions, that is, xl, Yl, x2, y2, x3, y3, x4, y4 are all known numbers. After determining the position of the built-in sensor 1, sensor 2, sensor 3, and sensor 4 of the mobile phone, when the mobile phone user taps on the tapping point (X, y) on the first operating platform at time t, the vibration mechanical wave is generated and directed After the four-way diffusion, the mobile phone can receive the vibration mechanical wave of the tapping signal at each time t1 (the time of the vibration mechanical wave received by the sensor 1), t 2 (the time of the vibration mechanical wave received by the sensor 2), 13 (the sensor 3 receives) The time of the vibration mechanical wave), t 4 (the time of the vibration mechanical wave received by the sensor 4), combined with the tapping time t of the tapping signal and the propagation velocity V of the vibration mechanical wave, the vibration mechanical wave is transmitted from the tapping point of the tapping signal to The distance of each sensor. The distance between each sensor and the tapping point position of the tapping signal is equal to the distance that the vibrating mechanical wave propagates from the tapping point of the tapping signal to each sensor, and thus the position coordinates of each sensor in the mobile phone in the positioning coordinate system of the mobile phone are combined. According to the propagation speed of the vibration mechanical wave multiplied by the time equal to the propagation distance of the vibration mechanical wave (ie, the distance between the position of the tap point and each sensor), the distance between each sensor and the position of the tap point and the propagation speed of the vibration mechanical wave of the tap signal are obtained, and the sensor receives The relationship between the time point of the vibration mechanical wave and the tapping time point of the tapping signal, such as The next 4 yuan 2 equations:

- ^) ² + ( Ί - - y) ² - t)xv

- 2 + O - yf = ( - t) x v

Since only v, t, x, and y are unknowns in the above data, the values of four unknowns of v, t, x, and y can be processed by giving a preset value of ¥, t, x, y and by iterative calculation. , the position (X, y) of the tapping point of the tapping signal on the first operating platform can be determined.

In the specific implementation, since the propagation speed of the vibration mechanical wave in the specific medium is fixed, and the medium used for the mobile phone case is fixed and known (because the material of the mobile phone case is determined by the mobile phone, the mobile phone case is used for the mobile phone case) The medium is also known to be identifiable. The propagation speed of the vibrating mechanical wave on the mobile phone casing is also fixed. It can be pre-stored in the mobile phone, and the mobile phone user performs a tapping action on the mobile phone (ie, the mobile phone casing). At this time, the propagation velocity V of the vibrating mechanical wave generated by the tap on the mobile phone becomes a known amount. When the tapping point is on the mobile phone (Fig. 2), the position of the tapping point of the tapping signal on the mobile phone in the positioning coordinate system (X, y) can be calculated by the three sensors. If there are the above four sensors, the calculation accuracy of the position of the tapping point can be estimated according to the least squares method. That is, in the embodiment, at least three sensors for acquiring the tapping signal are required, at most not limited.

As shown in Figure 3, if the tapping signal is outside the mobile phone, that is, when the first operating platform is a platform such as a desktop on which the mobile phone is placed, since the material of the desktop may be of various types (such as wood, plastic, iron, etc.), The propagation medium of the vibration mechanical wave of the hitting signal becomes an unfixed medium, and the mobile phone cannot predetermine the propagation velocity V of the vibration mechanical wave of the tapping signal on the desktop currently placed on the mobile phone, that is, the propagation velocity V of the vibration mechanical wave at this time is unknown. That is, when the tapping point of the tapping signal is on the platform such as the desktop on which the mobile phone is placed, the values of the four unknowns of v, t, x, and y can be determined according to the data obtained by the four sensors of the mobile phone, thereby determining the knocking. Letter The position of the tap point on the first operating platform. The mobile phone judges, according to the data obtained by the above sensor, the speed of the vibration mechanical wave on the current propagation medium (ie, the desktop on which the mobile phone is placed), when the mobile phone user taps the second time on the same medium, that is, the mobile phone user places the mobile phone. When the second time of tapping on the desktop, since the propagation velocity V of the vibration mechanical wave has been determined, the calculation accuracy of the tapping point position of the tapping signal on the first operating platform can be estimated based on the data acquired by the four sensors. . Specifically, the mobile phone user can obtain the 4-element second-order equation corresponding to the tapping signal of the second tap according to the above method, and can determine the propagation velocity v of the vibrating mechanical wave (ie, the vibrating mechanical wave) in the first tapping. The propagation speed on the desktop where the mobile phone is placed) is substituted into the above 4-ary equation 2, and then combined with any three of the equations to obtain the tapping signal of the second tap on the first operating platform. Is the coordinates (xl, yl) in the phone coordinate system. In addition, the user can directly obtain the tapping point position 2 of the tapping signal of the second tap on the first operating platform according to the above 4-ary equation 2 (assuming coordinates (x2, y2) in the mobile coordinate system. ), and according to the position 1 of the tapping point obtained in the previous processing, it is judged whether the coordinates of the tapping point position 2 (x2, y2) and the tapping point position 1 (xl, yl) coincide or whether the error is within the set error range, In this way, the calculation accuracy of the tapping point position of the tap signal on the first operating platform is estimated.

As shown in FIG. 6, when the mobile phone user performs a tapping action on the input keyboard drawing of the mobile phone, that is, the tapping point of the tapping signal on the first operating platform is on the keyboard map outside the mobile phone, when not on the mobile phone, The method of determining the position of the tapping point of the tapping signal on FIG. 3 determines the position of the tapping point on the first operating platform (keyboard map) in FIG. 6, and details are not described herein again.

When the mobile phone user needs to calibrate the relative position of the input keyboard drawing of the mobile phone and the mobile phone, the various calibration points on the input keyboard drawing of the mobile phone can be tapped. After the mobile phone obtains the tapping signal on the calibration point on the input keyboard drawing of the mobile phone through the built-in sensor, it can judge the respective calibration points according to the method of judging the tapping point position of the tapping signal on the first operating platform. The position in the positioning coordinate system of the mobile phone can also be passed through the various calibration points on the mobile phone. Enter the position on the keyboard drawing (ie the position of each calibration point in the positioning coordinate system of the input keyboard drawing) to further determine the relative position of the input keyboard drawing of the mobile phone and the mobile phone.

In the specific implementation, the characters on the input keyboard drawing of the mobile phone and the position of the calibration point on the input keyboard map are fixed, and the characters on the input keyboard drawing of the mobile phone and the positioning coordinates of the calibration point on the input keyboard drawing of the mobile phone can be pre-set in advance. The coordinates in the system are preset in the mobile phone application. The characters on the input keyboard drawing of the mobile phone and the input characters of the mobile phone application are corresponding to, and the coordinates of each character on the keyboard drawing can be input in advance (in the input keyboard of the mobile phone) The coordinates in the positioning coordinate system of the drawing are first established with the key value of the key input of the mobile phone application. For example, the key value of the character input key on the mobile phone application and the character on the input keyboard drawing of the mobile phone can be input on the mobile phone. The mapping relationship of the coordinates of the positioning coordinate system of the keyboard drawing is preset in the mobile phone. When the input keyboard drawing of the mobile phone and the mobile phone is placed on the auxiliary medium such as the desktop or the ground on which the mobile phone is placed, the relative position of the input keyboard drawing of the mobile phone and the mobile phone is an uncertain factor, and the mobile phone user uses the input keyboard drawing of the mobile phone as the mobile phone. Before inputting the device, it is necessary to first determine the relative position of the mobile phone and the input keyboard drawing of the mobile phone in the currently placed state, that is, to determine the coordinate relationship between the coordinates on the positioning coordinate system of the mobile phone and the coordinates of the positioning coordinate system of the input keyboard drawing of the mobile phone. .

Specifically, as shown in FIG. 6, the mobile phone user determines the relative positional relationship between the mobile phone and the current input keyboard drawing of the mobile phone (also the coordinates on the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone). When the coordinates of the transformation relationship), you can click the calibration button on the phone to activate the calibration function of the phone. When the mobile phone and the mobile phone input the keyboard drawing relative position relationship, the mobile phone's positioning coordinate system can be first marked as ( ^x , , the mobile phone's input keyboard map positioning coordinate system is marked as ( ^x , ^ ) The angle between the positioning coordinate system of the mobile phone and the coordinate system of the input keyboard map is recorded as ^ The angle between the X axis of the positioning coordinate system of the mobile phone and the X axis of the coordinate system of the input keyboard image can be recorded as ^ displacement ( ^Δ , the displacement is the coordinate of the origin of the coordinate system of the input keyboard diagram in the positioning coordinate system of the mobile phone, then the following coordinate transformation is X cos 6* sin 6* Ax X

y ― - sin 6* cos 6* y

1 0 0 1 1 Record the coordinates of each calibration point (calibration point 1, calibration point 2, calibration point 3, calibration point 4) on the input keyboard drawing of the mobile phone in the positioning coordinate system of the input keyboard diagram as i'^ i), ( ₂ , Λ ₂ ), ( , Λ ₃ ), ( ₄ , Λ ₄ ). After the mobile phone user taps each standard point on the input keyboard drawing of the mobile phone, the mobile phone can obtain the tapping signal at each calibration point through its built-in sensor, and determine the tapping signal according to the steps described in steps S201 and S202 above. The method of the position of the tapping point on the operating platform determines the coordinates of each calibration point in the positioning coordinate system of the mobile phone, and is respectively recorded as ( ' 1 ), ( ^X '^2), ( ' 3 ), (^4, ^ 4), you can list the following 4 relationships:

Cos 6* sin 6* Ax

1 0 0 1 15 At this time, in the above relationship (^1 ' 1 ), ( ^X : 2'y: 2), ( ^Χ : _3' Λ ₃ ), (^, ^), , (^2 , 2 ), ( , 3 ), ( ^Χ 'Λ ₄ ) is a known number, only 0 and (^' ) are unknowns, so any two of the above relations can be solved and ( , ).

Once and ( , ) are solved, the mobile phone can convert the coordinates of the tap signal in the positioning coordinate system of the mobile phone to obtain the coordinates on the positioning coordinate system of the input keyboard drawing of the mobile phone. The mobile phone obtains the coordinates of the button on the phone input keyboard drawing of the mobile phone in the current positioning state by tapping the signal, and learns the coordinates in the positioning coordinate system of the input keyboard drawing of the mobile phone according to the above coordinate transformation relationship. Then, the key value of the button corresponding to the coordinate in the positioning coordinate system of the input keyboard drawing of the mobile phone can be further known. Specifically, after determining, according to the obtained tapping signal on the first operating platform, the mobile phone knows that the tapping signal is in the positioning coordinate system of the mobile phone, and then according to the positioning coordinate system of the mobile phone and the positioning of the input keyboard drawing of the mobile phone. The transformation relationship of the coordinate system determines the coordinates of the positioning coordinate system of the phone input keyboard drawing corresponding to the tapping point position of the tap signal. According to the correspondence between the key value of the input button on the input keyboard drawing of the pre-stored mobile phone and the coordinate of the positioning coordinate system of the input keyboard drawing of the mobile phone, it can be determined that the mobile phone input keyboard drawing of the tapping signal is in the current placed state. The corresponding operation position (ie, the input button corresponding to the tapping point position of the tapping signal) and the key value of the input button on the mobile phone application, so as to input the current mobile phone into the tapping point position of the tapping signal on the keyboard drawing Maps to the key value of the input button on the phone app. For example, the coordinates (1, 3) in the positioning coordinate system of the mobile phone input keyboard drawing stored in the mobile phone in advance correspond to the key value of the input key corresponding to the character "Α" in the mobile phone character input application, when the mobile phone obtains the first The position of the tapping point of the tapping signal on the operating platform (the input keyboard drawing of the mobile phone) is after the coordinates in the positioning coordinate system of the mobile phone, according to the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone. When the relationship judgment is that the position of the tapping point of the tapping signal is (1, 3) on the input keyboard drawing of the mobile phone, the tapping signal can be input on the input keyboard of the mobile phone. The tap position on the map is mapped to the key value of the input button of the character "A" of the character input application of the mobile phone, and the tap signal is used as a trigger signal to trigger the corresponding response module output character "A" in the mobile phone application. For another example, as shown in FIG. 7 , if the first operating platform is a user-defined input drawing (such as an application operation diagram for playing music), and the mobile phone user pre-stores the positioning coordinate system of the input drawing in the mobile phone. The coordinates including the "thumb" in Fig. 7 are (2, 1) and the corresponding note is set to "du", that is, the coordinate (2, 1) corresponds to the key value of the input button of the note "du". Then, if the user taps the position of the tap point corresponding to the thumb, the mobile phone determines, according to the tapping signal, the position of the tapping point of the tapping signal in the positioning coordinate system of the mobile phone, according to the positioning coordinate system of the mobile phone and the mobile phone input. The transformation relationship of the positioning coordinate system of the drawing determines that the position of the tapping point on the input sheet of the mobile phone is a button corresponding to the "thumb", that is, the key point of the tapping point on the input pattern of the mobile phone corresponds to the button corresponding to the "thumb" The key value can be mapped to the key value of the button corresponding to "du", and the tapping signal can be used as a trigger signal to trigger the corresponding response module in the mobile phone according to the tapping strength of the tapping signal. Outputs notes of the corresponding volume level.

In addition, the mobile phone can complete the calibration of the relative position of the phone input keyboard drawing and the mobile phone according to any two calibration points on the current mobile phone input keyboard drawing, and can also be based on the relative position of the other two calibration points on the input keyboard drawing of the mobile phone. Perform calibration verification to determine whether the calibration of the positional relationship between the input keyboard drawing of the mobile phone and the mobile phone is accurate, and whether calibration needs to be performed again. Specifically, the mobile phone can complete the calibration of the relative positional relationship between the mobile phone input keyboard drawing and the mobile phone according to any two calibration points on the current mobile phone input keyboard drawing, and after the calibration, through the first operating platform (ie, the input keyboard drawing of the mobile phone) The tapping signal determines the tapping point position of the tapping signal (the position in the positioning coordinate system of the mobile phone). The corresponding mobile phone inputs the key value of the input key of the keyboard drawing (for example, the input key corresponding to the character "A"). In addition, the mobile phone user can also complete the calibration of the relative position of the mobile phone input keyboard drawing and the mobile phone through two other calibration points on the input keyboard drawing of the mobile phone, and judge the mobile phone according to the data of the calibration. The position of the tapping point of the tapping signal on the first operating platform (ie, the input keyboard drawing of the mobile phone) (the position in the positioning coordinate system of the mobile phone) corresponds to whether the key value of the input key on the mobile phone input keyboard drawing is The key value of the input button determined in the previous judgment is the same, that is, whether it is the key value of the input button corresponding to the character "A", thereby judging whether the positional relationship between the previously calibrated mobile phone and the input keyboard drawing of the mobile phone is correct.

52 06. Map, according to a preset correspondence between an operation position on the terminal input device and an operation position on the second operation platform, a tap point position of the tap signal on the terminal input device as The operating position on the second operating platform.

In the specific implementation, when the mobile phone user places the input keyboard drawing of the mobile phone on the desktop of the mobile phone and completes the calibration of the input keyboard drawing and the relative position of the mobile phone, the tapping action can be performed on the input keyboard drawing, and the tapping signal will pass through the desktop. Spread to the built-in sensor of the phone. After the built-in sensor of the mobile phone acquires the tapping signal, the tapping signal can be determined on the first operating platform (ie, the input keyboard drawing placed on the desktop of the mobile phone according to the method described in the above steps S 2 01 and step S 2 02). On the tapping point position, the position of the tapping point of the tapping signal in the positioning coordinate system of the mobile phone can be determined, and the tapping signal can be judged according to the relative positional relationship between the input keyboard drawing of the current mobile phone and the mobile phone. The position of the tap point on the operating platform corresponds to the operating position of the input keyboard drawing of the current mobile phone. After the mobile phone judges that the tapping point position of the tapping signal is in the operation position on the current mobile phone input keyboard drawing, the mobile phone may correspond to the operating position of the second operating platform of the mobile phone according to the input keyboard map preset in the mobile phone application. Relationship (for example The input relationship between the input keyboard drawing of the mobile phone and the key input value of the input method of the mobile phone application can input the input character of the mobile phone input keyboard drawing corresponding to the input on the keyboard image of the input method application of the mobile phone. The character, in turn, maps the tapping point position of the tapping signal on the input keyboard drawing of the mobile phone to the key value of the input soft keyboard of the input method applied by the mobile phone. The second operating platform of the mobile phone described in this embodiment may include an input interface of an application of the mobile phone, an input end of the input soft keyboard of the input method of the mobile phone (ie, a character input soft keyboard of the mobile phone), and the like.

As shown in Figure 7, when the first operating platform is a custom input drawing for the mobile phone user, the relative position of the input drawing and the mobile phone can also be calibrated according to the above method, and the input drawing of the mobile phone user can be customized and the corresponding mobile phone built in the mobile phone. The key value of the input soft keyboard of the application is used to establish a connection, and according to the above method, after the tapping point position of the tapping signal is determined on the operation position of the input drawing of the mobile phone user, the tapping point of the tapping signal can be The location is mapped to the operating position of the second operating platform of the mobile phone (ie, the input soft keyboard of the corresponding mobile phone application built in the mobile phone) (specifically, the key value of the key input to the soft keyboard).

S 207, using the tapping signal as a trigger signal on an operation position on the second operating platform, and generating a tapping strength corresponding to the tapping signal according to a tapping intensity of the tapping signal. The signal strength of the terminal input signal.

In a specific implementation, after the mobile phone maps the location of the tapping point of the tapping signal on the first operating platform to the operating location of the second operating platform of the mobile phone, the tapping signal can be used as the operating position of the second operating platform of the mobile phone. The trigger signal on the mobile phone generates a mobile phone input signal corresponding to the trigger signal. When the first operating platform is the input keyboard drawing of the mobile phone (as shown in FIG. 6 ), the mobile phone determines that the tapping signal is on the input keyboard drawing of the mobile phone and knocks the tapping signal on the input keyboard map of the mobile phone. After the location of the hit point is mapped to the key value of the input soft keyboard of the input method applied by the mobile phone, the mobile phone can adjust the character corresponding to the key value in the input method of the mobile phone, and the character is used as the input of the input method of the mobile phone. Character output to mobile phone In the input box of the interface, the input signal of the mobile phone is generated.

When the first operating platform is a custom input drawing for the mobile phone user (as shown in FIG. 7), the mobile phone user customizes the input sound corresponding to each operation position on the drawing (for example, the pitch corresponding to the piano key), and then the mobile phone judges After knowing the position of the tap signal on the input sheet and mapping the tapping point position of the tap signal on the input sheet to the key value of the sound button, the mobile phone can adjust the key value of the sound button in the corresponding application. The corresponding tone, and the corresponding music is output according to the tone. In the method for generating a terminal input character described above, as long as the input drawing of the mobile phone user is calibrated and the position is determined, all the keys on the input drawing in the positioning coordinate system of the mobile phone are known numbers for the mobile phone. When the mobile phone user taps on the drawing, the mobile phone can determine the button of the mobile phone user's tap according to the tapping point position of the tapping signal, and use the button as a trigger signal of the mobile phone input signal, and according to the tapping The tapping intensity of the signal, generating a mobile phone input signal corresponding to the signal strength of the tapping strength of the tapping signal, playing a piece of music played by the user of the mobile phone, and completing the conversion of the tapping signal to the input signal of the mobile phone.

The embodiment of the invention can map the location of the tapping point of the tapping signal on the operating platform such as the input keyboard drawing of the mobile phone or the input drawing of the mobile phone to the key value of the input soft keyboard of the input method of the mobile phone or the mobile phone.

Specifically, the collecting unit 31 may be a location coordinate from the memory in which the respective sensors in the terminal are located in the positioning coordinate system of the terminal. The coordinate axis of the positioning coordinate system of the mobile phone is preset by using a specific point on the mobile phone as a coordinate origin, and according to the positioning coordinate system, the position of each sensor in the mobile phone in the positioning coordinate system can be determined, as shown in FIG. 2 After the positioning coordinate system of the mobile phone is used, the position coordinates of each sensor in the mobile phone in the positioning coordinate system of the mobile phone are determined, so that the position coordinates of each sensor in the positioning coordinate system of the mobile phone can be stored in the memory, when needed. Read it.

The mapping module 5 0 is specifically configured to:

Matching a position of the tapping point of the tapping signal on the first operating platform in a positioning coordinate system of the terminal with a positioning database preset in the terminal, and determining that the tapping signal is in the Mapping an operation position on the second operating platform corresponding to a tapping point position on the first operating platform, mapping a tapping point position of the tapping signal on the first operating platform It is the operating position on the second operating platform.

The generating module 70 is specifically configured to:

The tapping signal is used as a trigger signal on an operating position on the second operating platform to generate a terminal input signal. Specifically, the tapping signal may be used as a trigger signal on an operation position on the second operating platform, and a tapping intensity corresponding to the tapping signal may be generated according to a tapping intensity of the tapping signal. Terminal input signal for signal strength.

In a specific implementation, the first operating platform described in this embodiment may include: a terminal body, a surface of a flat object on which the terminal is placed, a terminal input device, and the like. For example, the first operating platform described in this embodiment may be a mobile phone. In itself, or placed on the horizontal desktop of the mobile phone, the ground, the input keyboard drawing of the mobile phone, the user-defined input drawing of the mobile phone, and the like. When the user uses the corresponding function of the terminal described in this embodiment, the tapping action can be performed on the mobile phone (including the back of the mobile phone or other parts on the mobile phone) or the desktop of the mobile phone, and the acquiring module in the mobile phone 1 0 can obtain the tapping signal on the mobile phone or the desktop of the mobile phone through its built-in sensor to generate the input signal of the mobile phone according to the tapping signal. The tapping signal on the first operating platform may include: a vibration mechanical wave, a tapping time, a tapping intensity, and the like. For example, when the mobile phone user plays the game using the piano in the mobile application, if the mobile phone is required to generate an input signal of the piano playing game according to the tapping signal, the mobile phone function can be turned on before the game is played, that is, according to the first The tapping signal on the operating platform generates a phone function that inputs the input signal of the piano playing game. After the mobile phone user activates the above functions, the tapping action of playing music can be performed on the back of the mobile phone or on the desktop where the mobile phone is placed, and the acquisition module 10 of the mobile phone obtains the back of the mobile phone or the desktop of the mobile phone through its built-in sensor. After the signal is tapped, the tapping signal can be sent to a module in the mobile phone for generating a corresponding input signal to generate an input signal of the mobile phone piano playing through the corresponding mobile phone module. The mobile phone user does not need to input the playing signal through the virtual keyboard of the piano playing the game, and only needs to perform the tapping action of the playing music on the first operating platform to complete the signal input of the piano playing. In the specific implementation, in order to prevent the mobile phone from randomly generating a mobile phone input signal according to the tapping signal on the mobile phone or the desktop of the mobile phone, affecting the normal use of the mobile phone, a startup mode of starting the function of generating the mobile phone input signal of the mobile phone may be set. When the mobile phone user wants to activate the mobile phone function (that is, the mobile phone function for generating the mobile phone input signal according to the tap signal), the tapping action can be performed at the designated position on the first operating platform, and the acquiring module 10 of the mobile phone acquires the specified position. After the tap signal is on, the corresponding function of the mobile phone can be activated. For example, in order to prevent the input signal of the piano playing game of the mobile phone from being generated according to the tapping signal on the mobile phone or the desktop of the mobile phone, the mobile phone user can make a corresponding tapping at the designated position of the mobile phone when starting to play the music. Action, used to activate the piano playing function of the mobile phone. After the mobile phone acquisition module 10 obtains the tapping signal at the designated position of the mobile phone through the built-in sensor of the mobile phone, the piano playing function of the mobile phone can be started by itself. For example, when a mobile phone user plays the game application using the piano of the mobile phone, he can first tap each of the top left corner, the upper right corner, the lower right corner, and the lower left corner of the mobile phone to indicate that the playing is started, and the acquisition module of the mobile phone acquires 10 After the tapping signal on the above mobile phone position, the corresponding mobile phone function can be activated (ie, the function of starting the mobile phone to generate an input signal of the piano playing according to the tapping signal); when the mobile phone user wants to end the game, the mobile phone can be used in the mobile phone. The lower left corner, the lower right corner, the upper right corner, and the upper left corner are tapped one by one, indicating that the end playing is performed, and after the mobile phone acquiring module 10 obtains the tapping signal at the above position, the mobile game application server can be turned off by itself. The input signal that generates the piano play is no longer received. In addition, the mobile phone user can also tap on the top, bottom, left, and right sides of the mobile phone to start playing, and tap on the right, left, bottom, and top of the mobile phone to end the playing. The manner in which the above actions are started and ended is only an example, not an exhaustive one.

After the acquisition module 10 of the mobile phone acquires the tapping signal on the first operating platform by using the built-in sensor of the mobile phone, the positioning module 30 can determine, according to the tapping signal acquired by the acquiring module 10, the tapping signal in the first operation. The location of the tap point on the platform. Specifically, the positioning coordinates of a mobile phone may be set first with a specific point on the mobile phone (for example, the center of gravity of the mobile phone) as a coordinate origin. System, set the positioning coordinate system of the mobile phone in the plane where the mobile phone display screen is located or the plane where the mobile phone back cover is located, with the bottom direction of the mobile phone as the X axis, and the mobile phone side direction as the y axis, used to determine the mobile phone or place The tapping point position of the tapping signal on the operating platform such as the desktop of the mobile phone. Specifically, the coordinate axis of the positioning coordinate system of the mobile phone may be preset in advance for the coordinate origin of the specific point on the mobile phone, and the position of each sensor in the mobile phone in the positioning coordinate system is determined according to the positioning coordinate system, as shown in FIG. 2 After the positioning coordinate system of the mobile phone is set, the position coordinates of each sensor in the mobile phone in the positioning coordinate system of the mobile phone are determined. After determining the positioning coordinate system of the mobile phone, the collecting unit 31 in the positioning module 30 of the mobile phone can be based on the position coordinates of each sensor in the positioning coordinate system in the mobile phone, as shown in FIG. 2 . After determining the positioning coordinate system of the mobile phone, the collecting unit 31 can collect the position coordinates of the sensor 1, the sensor 2, the sensor 3, and the sensor 4 in the positioning coordinate system as (xl, yl), (x2, y2),

(x 3 , y3 ) , (x4 , y4 ) , wherein, since the position of the built-in sensor of the mobile phone relative to the mobile phone is a fixed position, the positions of the above-mentioned respective sensors in the positioning coordinate system are all determined positions, that is, xl, yl , x2, y2, x3, y3, x4, y4 are all known numbers. After the collection unit 31 collects the position coordinates of the built-in sensor 1, the sensor 2, the sensor 3, and the sensor 4, when the mobile phone user taps on the tapping point (X, y) on the first operating platform at time t, After the vibration mechanical wave is generated and diffused to the surroundings, the first processing unit 32 in the positioning module 30 of the mobile phone can receive the vibration mechanical wave of the tap signal according to each sensor at time t1 (the time of the vibration mechanical wave received by the sensor 1), t 2 (the time of the vibration mechanical wave received by the sensor 2), t 3 (the time of the vibration mechanical wave received by the sensor 3), t 4 (the time of the vibration mechanical wave received by the sensor 4), the time at which the tapping signal is generated, that is, the tapping signal The tapping time t and the propagation velocity V of the vibrating mechanical wave calculate the distance between the respective sensors in the mobile phone and the tapping point position of the tapping signal. The first processing unit 32 of the mobile phone multiplies the propagation speed of the vibration mechanical wave by a time equal to the sensing distance of the vibration mechanical wave (ie, the distance between the tapping point position and each sensor), and the time at which the vibration mechanical wave of the tapping signal is received by each sensor and Tap The tapping time of the signal and the propagation speed of the vibrating mechanical wave are combined with the position coordinates of the respective sensors in the mobile phone in the positioning coordinate system, and the distance between each sensor and the position of the striking point and the propagation speed of the vibrating mechanical wave of the striking signal are processed, and the sensor receives The relationship between the time point of the vibration mechanical wave and the tapping time point of the tapping signal is as follows:

- yf - t) xv

- 2 + O - yf - t) xv

Since the above data, only the v, t, x, y is the unknown, to be by v, t, x, y a predetermined value, and _v can be obtained by an iterative calculation process, t, x, y four unknowns The value of the tapping point (X, y) of the tapping signal on the first operating platform.

In the specific implementation, since the propagation speed of the vibration mechanical wave in the specific medium is fixed, and the medium used for the mobile phone case is fixed and known (because the material of the mobile phone case is determined by the mobile phone, the mobile phone case is used for the mobile phone case) The medium is also known to be identifiable. The propagation speed of the vibrating mechanical wave on the casing of the mobile phone is also fixed and can be stored in advance in the mobile phone. When the mobile phone user makes a tapping action on the mobile phone (ie, the mobile phone casing), the propagation speed V of the vibration mechanical wave generated by the tapping on the mobile phone becomes a known amount, and in the process of processing the above equation, the propagation speed V can be treated as a known number. When the tapping point is on the mobile phone, the position of the tapping point of the tapping signal on the mobile phone in the positioning coordinate system (X, y) can be calculated by the three sensors. If there are the above four sensors, the calculation accuracy of the position of the tapping point can be estimated according to the least square method. In this embodiment, at least three sensors for acquiring the tapping signal are required, and at most, at most.

As shown in Figure 3, if the tapping signal is outside the mobile phone, that is, when the first operating platform is a platform such as a desktop on which the mobile phone is placed, there may be many types of materials for the desktop (for example, wood, plastic, Iron sheet, etc., so that the propagation medium of the vibration mechanical wave of the tapping signal becomes an unfixed medium, and the mobile phone cannot predetermine the propagation velocity V of the vibration mechanical wave of the tapping signal on the desktop currently placed on the mobile phone, that is, the vibration mechanical wave at this time The propagation velocity V is unknown. When the tapping point of the tapping signal is located on a platform such as a desktop on which the mobile phone is placed, the first processing unit 32 can obtain the values of the four unknowns of v, t, x, and y by acquiring the corresponding data by the four sensors of the mobile phone. The tapping point position of the tap signal on the first operating platform is determined. According to the data acquired by the first processing unit 32, after the propagation speed of the vibration mechanical wave on the current propagation medium (ie, the desktop on which the mobile phone is placed) is determined, when the mobile phone user taps the second time on the same medium, the mobile phone user is placed. When the mobile phone's desktop is tapped for the second time, since the propagation velocity V of the vibrating mechanical wave has been determined, the mobile phone can initially estimate the tapping point position of the tapping signal on the first operating platform based on the data acquired by the above four sensors. The accuracy of the calculation. Specifically, the mobile phone user can obtain the 4-element second-order equation corresponding to the tapping signal of the second tap according to the above method, and can determine the propagation velocity v of the vibrating mechanical wave (ie, the vibrating mechanical wave) in the first tapping. The propagation speed on the desktop where the mobile phone is placed) is substituted into the above 4-ary equation 2, and then combined with any three of the equations to obtain the tapping signal of the second tap on the first operating platform. Is the coordinates (xl, yl) in the phone coordinate system. In addition, it is also possible to directly obtain the tapping point position 2 of the tapping signal of the second tap on the first operating platform according to the above-mentioned 4-ary binary equation (assuming coordinates (x2, y2) in the mobile coordinate system) And judging whether the coordinates of the tapping point position 2 (x2, y2) and the tapping point position 1 (xl, yl) are coincident or the error is within the set error range according to the tapping point position 1 obtained in the previous processing, This estimates the accuracy of the calculation of the tapping point position of the tap signal on the first operating platform.

In a specific implementation, the second operating platform described in this embodiment is an input interface of an application of the terminal, an input platform of a terminal such as a character input soft keyboard of the terminal. For example, the virtual keyboard of the piano playing game in the application on the mobile phone, the input soft keyboard of the mobile phone input method, the shooting button on the camera function interface of the mobile phone, and the like. The above operation buttons are only examples, not poor Lift. The operation position on the second operating platform may be: a key value of an input button of the application of the terminal, a key value of a character input soft keyboard of the terminal, a touch position of the touch screen of the terminal, etc., for example, in an application on the mobile phone The key value of the key of the piano playing game, the key value of the character input keyboard of the mobile phone input method, the key value of the shooting key of the camera function of the mobile phone, and the like.

After the positioning module 30 of the mobile phone determines that the tapping point position of the tapping signal on the first operating platform is known, the tapping point of the tapping signal on the first operating platform can be located on the mobile phone through the mapping module 50. The position in the coordinate system is matched with the pre-stored positioning database, and the operation position on the second operating platform of the mobile phone corresponding to the tapping point position of the tapping signal on the first operating platform is determined by database matching, and will be knocked The location of the hitting point on the first operating platform is mapped to the operating position on the second operating platform of the handset. In a specific implementation, a perceptible tapping area of the mobile phone may be set in advance by using the positioning coordinate system of the mobile phone as a reference system. For example, a side length of the mobile phone's positioning coordinate system may be set in advance as a length of 2 X. , width 2Y (where the specific value of X, Y can be set at the same time as setting the positioning coordinate system of the mobile phone, or can be customized by the user of the mobile phone), the square area of the mobile phone is the perceptible area of the mobile phone, and the above can be set The operating position on the second operating platform of the mobile phone corresponding to each tapping position in the sensing area (specifically, the key value of the button on the second operating platform of the mobile phone) is stored, and all the corresponding relationships are stored as a positioning database. When the mobile phone user places the mobile phone smoothly and determines the first operating platform of the mobile phone (such as the mobile phone body or the desktop on which the mobile phone is placed), the mobile phone can determine the perceptible area on the current first operating platform according to its positioning coordinate system (for example) a specific area on the phone body or a specific area on the desktop where the phone is placed). When the mobile phone user performs a tapping action within the perceptible area of the first operating platform, the mapping module 50 of the mobile phone can position the tapping point of the tapping signal on the first operating platform in the positioning coordinate system. Matching with the pre-stored positioning database to determine the operating position on the second operating platform corresponding to the tapping point position on the current first operating platform. For example, as shown in FIG. 2, after the mobile phone user performs a tapping action on the back of the mobile phone, the positioning module 30 of the mobile phone determines that the tapping signal on the mobile phone is known. When the tapping point position is used, the mapping module 50 can be matched by the built-in database of the mobile phone, and the button on the virtual key on the piano playing game of the mobile phone corresponding to the tapping point position of the current tap signal on the current mobile phone is determined. Key value, and map the location of the tap point to the key value of the virtual key, and the generating module 70 of the mobile phone uses the tapping signal as a trigger signal on the key to generate a piano bullet corresponding to the trigger signal for the terminal. Play the input signal of the game. For example, as shown in FIG. 4, when the positioning module 30 determines that the tapping point of the tapping signal on the back of the mobile phone is a point on the upper left corner of the back of the mobile phone (the tapping point shown in FIG. 4), the mapping module 5 0 can be matched by the built-in positioning database of the mobile phone to know that the virtual key on the piano playing game of the mobile phone corresponding to the current tapping point position is the third button from the left of the keyboard (ie, the mapping point corresponding to FIG. 4) Press the button) to map the tapping point on the back of the phone to the key of the phone's piano playing game. Similarly, when the positioning module 30 determines that the tapping point position of the tapping signal is at other positions on the back of the mobile phone, the mapping module 50 can also perform matching by using the built-in positioning database of the mobile phone to determine the tapping point of the tapping signal. The key value of the button on the virtual key corresponding to the position. After the mapping module 50 determines that the key value of the specific key of the virtual keyboard of the piano playing game of the mobile phone corresponding to the tapping point position of the tapping signal is known, the generating module 70 of the mobile phone can use the tapping signal as the key. The trigger signal of the key value is used to trigger the virtual piano application built in the mobile phone, and the music playing manager of the mobile phone is called by the application of the built-in virtual piano of the mobile phone to play the music corresponding to the tapping signal. After the mapping module 50 of the mobile phone maps the location of the tapping point of the tapping signal to the key value of the button on the virtual piano application on the mobile phone, the generating module 70 converts the tapping signal into a virtual piano application of the mobile phone. The trigger signal of the key value of the button is used by the virtual piano application of the mobile phone to call the music playing manager to emit a sound corresponding to the pitch of the specific button, and adjust the tapping strength according to the tapping strength of the tapping signal. The music of the corresponding volume, that is, the mobile phone can emit music of different pitches at different volume according to the tapping position of the mobile phone user and the tapping intensity. The user can adjust the pitch and volume of the music emitted by the mobile phone according to his own tapping action, and better mobilize the mobile phone user to play music through the mobile phone. The interest and passion can also trigger the inspiration of the music creation of mobile phone users, and improve the fun of signal input.

The mobile phone described in this embodiment can map the location of the tapping point of the tapping signal on the operating platform such as the desktop of the mobile phone or the mobile phone to the operating position on the second operating platform of the mobile phone (specifically, it can be mapped to the second operation). The key value of the button on the platform, etc., and the tapping signal is used as a trigger signal at the operating position to trigger an internal application of the mobile phone, generate a mobile phone input signal corresponding to the trigger signal, and expand the input of the mobile phone The signal generation path improves the interest of generating the input signal of the mobile phone and improves the user experience of the mobile phone.

Wherein, the generating module 7 0 is specifically used for:

The first operating platform described in this embodiment may include: a terminal body, a flat object surface on which the terminal is placed, an instant access device of the terminal, an input keyboard drawing of the terminal, an input drawing customized by the terminal user, and the like. For example, the first operating platform described in this embodiment may be an instant access device of the mobile phone (ie, a non-mobile phone fixed access device, which can be accessed as an input device of the mobile phone in real time and can be determined by calibration when accessing. a device that has a location relationship between the device and the mobile phone, such as an external physical keyboard of the mobile phone, or the mobile phone itself, or a desktop on which the mobile phone is placed, or a mobile phone user prints out and places it on the desktop where the mobile phone is placed The input keyboard drawing of the mobile phone on the mobile phone (such as the keyboard diagram shown in Figure 6), or the user input print drawing of the mobile phone user and placed with the mobile phone on the desktop where the mobile phone is placed (for example, as shown in Figure 7) Auxiliary drawings) and so on. In the specific implementation, the input keyboard drawing of the above mobile phone and the input drawing of the user defined by the mobile phone are a special type of paper, and the paper includes information such as an input keyboard picture.

When the user uses the corresponding function of the terminal described in this embodiment, the input keyboard drawing of the mobile phone or the input keyboard drawing of the mobile phone user can be smoothly placed on the desktop where the mobile phone is placed (ie, the desktop where the mobile phone is located), and Input the keyboard drawing or the user-defined input drawing of the mobile phone to make a tapping action. The acquiring module 10 in the mobile phone can obtain the input keyboard drawing of the mobile phone or the input drawing of the customized user of the mobile phone through the tapping signal acquisition module such as the built-in sensor. The tap signal on the top generates an input signal of the terminal according to the tap signal through a corresponding module in the mobile phone. The tapping signal on the first operating platform may include: a vibration mechanical wave, a tapping time, a tapping intensity, and the like. For example, when the mobile phone user uses the input keyboard drawing of the mobile phone to input the mobile phone character, if the mobile phone is required to generate a character input signal according to the tapping signal, the mobile phone function can be turned on according to the first operating platform (ie, the input keyboard drawing of the mobile phone). The tapping signal on the phone generates a character input signal for the phone function. After the mobile phone user activates the above mobile phone function, the tapping action can be performed on the input keyboard drawing of the mobile phone, and after the mobile phone acquiring module 10 obtains the tapping signal on the input keyboard drawing of the mobile phone through the built-in sensor, the knocking can be performed. The hit signal is sent to the corresponding module in the mobile phone, and the mobile phone module can generate an input signal of the mobile phone input method according to the tap signal. In a specific implementation, the mobile phone obtains a tapping signal on the input keyboard drawing (terminal input device) of the mobile phone through its built-in sensor, and before inputting the input signal of the mobile phone input method according to the tapping signal, it is also necessary to confirm the input keyboard drawing of the mobile phone first. The relative position with the mobile phone, that is, the transformation relationship between the positioning coordinate system of the input keyboard drawing of the mobile phone and the positioning coordinate system of the mobile phone needs to be determined. Specifically, the mobile phone user needs to tap the calibration point on the input keyboard drawing of the mobile phone to the relative position of the input keyboard drawing of the mobile phone and the mobile phone. Perform calibration.

After the acquisition module 10 of the mobile phone acquires the tapping signal on the first operating platform by using the built-in sensor of the mobile phone, the positioning module 30 can determine the tapping point of the tapping signal on the first operating platform according to the tapping signal. position. Specifically, a positioning coordinate system of a mobile phone may be set with a specific point on the mobile phone (for example, the center of gravity of the mobile phone) as a coordinate origin, and the mobile phone may be set in a plane where the mobile phone display screen is located or a plane where the mobile phone back cover is located. Positioning the coordinate system, the direction of the bottom edge of the mobile phone is the X axis, and the direction of the side of the mobile phone is the y axis, which is used to determine the tapping point position of the tapping signal on the operating platform such as the mobile phone or the desktop on which the mobile phone is placed (ie, the tapping signal is on the mobile phone) Position in the positioning coordinate system). Specifically, a specific point on the mobile phone (for example, the center of gravity of the mobile phone) may be used to preset a coordinate axis of the positioning coordinate system for the coordinate origin, and according to the positioning coordinate system, determine the position of each sensor in the mobile phone in the positioning coordinate system, such as Figure 2 shows. After setting the positioning coordinate system of the mobile phone, the position coordinates of the sensor in the mobile phone in the positioning coordinate system of the mobile phone are determined, and the position coordinates of the sensor in the mobile phone in the positioning coordinate system of the mobile phone are stored in the memory. The collection unit 31 in the positioning module 30 of the mobile phone can collect the position coordinates of each sensor in the mobile phone in the positioning coordinate system of the mobile phone. Specifically, after the positioning coordinate system of the mobile phone is set, the collecting unit 31 can collect the position coordinates of the sensor 1, the sensor 2, the sensor 3, and the sensor 4 in the positioning coordinate system as (xl, yl), ( X2 , y2 ), ( x 3 , y3 ) , (x4 , y4 ) , wherein, since the position of the built-in sensor of the mobile phone relative to the mobile phone is a fixed position, the positions of the above-mentioned respective sensors in the positioning coordinate system are determined positions , ie xl, yl, x2, y2, x3, y3, x4, y4 are all known numbers. After the collection unit 31 collects the positions of the built-in sensor 1, the sensor 2, the sensor 3, and the sensor 4, when the mobile phone user taps on the tapping point (X, y) on the first operating platform at time t, After the vibration mechanical wave is generated and diffused to the surroundings, the first processing unit 32 in the positioning module 30 of the mobile phone can receive the time t1 of the vibration mechanical wave of the tap signal according to each sensor (the time of the vibration mechanical wave received by the sensor 1), t 2 (sensor 2 receives vibration of mechanical waves Time), t3 (time of vibration mechanical wave received by sensor 3), t4 (time of vibration mechanical wave received by sensor 4), combined with the tapping time t of the tapping signal and the propagation velocity V of the vibration mechanical wave, calculate each sensor in the mobile phone The distance from the tapping point of the tapping signal. The first processing unit 32 of the mobile phone receives the data of the vibration mechanical wave of the tap signal and the tapping time of the tapping signal, the propagation speed of the vibration mechanical wave, and the like, and can be combined with each sensor in the mobile phone in the positioning coordinate system. The position coordinate is obtained by multiplying the propagation velocity of the vibration mechanical wave by the time equal to the sensing distance of the vibration mechanical wave (ie, the distance between the tapping point and each sensor) to obtain the distance between each sensor and the position of the tapping point and the vibration mechanical wave of the tapping signal. The relationship between the propagation speed, the time point at which the sensor receives the vibrating mechanical wave, and the tapping time of the tapping signal is as follows:

-^) ² +( Ί - -y) ² -t)xv

- 2 + O -yf =( -t)xv

Since v, t, x, and y are unknowns in the above data, a predetermined value is obtained by v, t, x, y, and the values of four unknowns of v, t, x, and y can be processed by iterative calculation. The tapping point position (X, y) of the tapping signal on the first operating platform can be determined.

In the specific implementation, since the propagation speed of the vibration mechanical wave in the specific medium is fixed, and the medium used for the mobile phone case is fixed and known (because the material of the mobile phone case is determined by the mobile phone, the mobile phone case is used for the mobile phone case) The medium is also known to be identifiable. The propagation speed of the vibrating mechanical wave on the mobile phone casing is also fixed. It can be pre-stored in the mobile phone, and the mobile phone user performs a tapping action on the mobile phone (ie, the mobile phone casing). At this time, the propagation velocity V of the vibrating mechanical wave generated by the tap on the mobile phone becomes a known amount. When the tapping point is on the mobile phone (as shown in Fig. 2), the position (X, y) of the tapping point of the tapping signal on the mobile phone in the positioning coordinate system can be calculated by the three sensors. If there are 4 sensors above, then The calculation accuracy of the position of the tapping point is estimated according to the least squares method, that is, in the embodiment, the sensor for acquiring the tapping signal needs at least three, at most not limited.

As shown in Figure 3, if the tapping signal is outside the mobile phone, that is, when the first operating platform is a platform such as a desktop on which the mobile phone is placed, since the material of the desktop may be of various types (such as wood, plastic, iron, etc.), The propagation medium of the vibration mechanical wave of the hitting signal becomes an unfixed medium, and the mobile phone cannot predetermine the propagation velocity V of the vibration mechanical wave of the tapping signal on the desktop currently placed on the mobile phone, that is, the propagation velocity V of the vibration mechanical wave at this time is unknown. When the tapping point of the tapping signal is on the platform such as the desktop on which the mobile phone is placed, the corresponding data can be obtained according to the four sensors of the mobile phone, and the obtained data is used to determine the four unknowns of v, t, x, and y. a value to determine the location of the tapping point of the tapping signal on the first operating platform.

The mobile phone judges, according to the data obtained by the above sensor, the speed of the vibration mechanical wave on the current propagation medium (ie, the desktop on which the mobile phone is placed), when the mobile phone user taps the second time on the same medium, that is, the mobile phone user places the mobile phone. When tapping the second time on the desktop, since the propagation velocity V of the vibration mechanical wave has been determined, the calculation accuracy of the tapping point position of the tapping signal on the first operating platform can be estimated based on the data acquired by the four sensors. . Specifically, the first processing unit 32 of the mobile phone can obtain the 4-element second-order equation corresponding to the tapping signal of the second tap according to the foregoing method, and can determine the propagation speed of the vibrating mechanical wave that is known in the first tap. (that is, the propagation speed of the vibrating mechanical wave on the desktop placed on the mobile phone) is substituted into the above 4-ary equation, and then combined with any three of the equations to obtain the tapping point of the tapping signal of the second tap on the first operating platform. Position 1 (assumed to be the coordinates (xl, yl) in the phone coordinate system). In addition, the tapping point of the tapping signal of the second tapping on the first operating platform can be directly obtained according to the obtained 4-ary quadratic equation obtained (assuming coordinates in the mobile phone coordinate system (x2). Y2 ) ) , and judge whether the coordinates of the tapping point position 1 ( x 2 , y2 ) and the tapping point position 1 ( xl, yl ) coincide or whether the error is in the set error according to the tapping point position 1 obtained in the previous processing. In this way, to estimate the tapping of the tapping signal on the first operating platform The calculation accuracy of the point position.

As shown in FIG. 6, when the mobile phone user performs a tapping action on the input keyboard drawing of the mobile phone, that is, the tapping point of the tapping signal on the first operating platform is on the keyboard map outside the mobile phone, when not on the mobile phone, the positioning module 30 is The position of the tapping point on the first operating platform (keyboard map) in FIG. 6 can be determined according to the above method for determining the position of the tapping point of the tapping signal on FIG. 3, and details are not described herein again.

In the specific implementation, the characters on the input keyboard map of the mobile phone and the position of the calibration point on the input keyboard map are fixed, and the characters on the input keyboard drawing of the mobile phone and the positioning coordinates of the calibration point on the input keyboard drawing of the mobile phone can be pre-set in advance. The coordinates in the system are preset in the mobile phone application, and the characters input into the keyboard drawing and the coordinates corresponding to the calibration point (coordinates in the positioning coordinate system of the input keyboard drawing of the mobile phone) and the character input of the mobile phone application can be input in advance. The key value of the button is first established, and the operation position (ie, the coordinates corresponding to each character and the calibration point) on the phone keyboard input map is mapped to the key value of the character input button on the mobile phone application. In a specific implementation, since the mobile phone can only judge the position of the tapping signal in the positioning coordinate system of the mobile phone according to the obtained tapping signal, the location of the tapping point on the mobile phone input keyboard drawing is mapped to the mobile phone. The key value of the character input button on the application needs to convert the position of the tap signal in the positioning coordinate system of the mobile phone to the corresponding position on the input keyboard drawing of the mobile phone, and then the coordinates of the positioning coordinate system of the mobile phone can be determined first. The transformation relationship of the coordinates of the positioning coordinate system of the input keyboard drawing of the mobile phone.

In a specific implementation, as shown in FIG. 6, the mobile phone user determines the relative positional relationship between the mobile phone and the input keyboard drawing of the mobile phone in the current placement state (also the coordinates on the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone). When the coordinates of the coordinates are changed, you can click the calibration button on the phone to activate the calibration function of the phone. When the mobile phone and the mobile phone input the keyboard drawing relative position relationship, the mobile phone's positioning coordinate system can be first marked as ( ^x , , the mobile phone's input keyboard map positioning coordinate system is marked as ( ^x , ^ ) The angle between the positioning coordinate system of the mobile phone and the coordinate system of the input keyboard map is recorded as ^the X axis of the positioning coordinate system of the mobile phone Enter the angle of the X-axis of the coordinate system of the keyboard diagram as ^ displacement is recorded as (^, displacement is the coordinate of the origin of the coordinate system of the input keyboard diagram in the positioning coordinate system of the mobile phone, then the following coordinate transformation relationship:

X cos 6* sin 6* Ax X

y ― - sin 6* cos 6* y

1 0 0 1 1 Record the coordinates of each calibration point (calibration point 1, calibration point 2, calibration point 3, calibration point 4) on the input keyboard drawing of the mobile phone in the positioning coordinate system of the input keyboard diagram as i'^ i), ( ^X '^), ( ₄ ' Λ ₄ ). When the mobile phone user taps each calibration point on the input keyboard drawing of the mobile phone, the calibration module 80 of the mobile phone can obtain the tapping signal on the calibration point on the input keyboard drawing of the mobile phone through the built-in sensor of the mobile phone, and through the above The first processing unit 32 knows the position of each calibration point in the positioning coordinate system of the handset. Specifically, the calibration module 90 can determine the coordinates of the calibration point on the input keyboard drawing of the mobile phone in the positioning coordinate system of the mobile phone, and record them as ( ' 1 ), ( ' ₂ ), ( ' 3 ), ( ₄ , 4 ), you can list the following four relationships:

^X sA cos 6* sin 6* Ax ^X sA

― - sin Θ cos 6*

At this time, in the above relationship (^1 ' 1 ), ( ^X : 2'y: 2), ( ^Χ : _3' Λ ₃ ), (^, ^), ,

(^2, 2), (^4 ' 4 ) are known numbers, only and (^' ) are unknown, calibration module

90 can take any of the above two relations to solve and ( , ).

Once and ( , ) are solved, the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard of the mobile phone can be determined. After the calibration module 90 determines the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the mobile phone input keyboard drawing, the coordinate of each button in the input coordinate system of the mobile phone obtained by the mobile phone on the positioning coordinate system of the mobile phone can be obtained. Substituting into the above coordinate transformation relationship, the coordinates of each button on the positioning coordinate system of the input keyboard drawing of the mobile phone are obtained.

In addition, the mobile phone can complete the calibration of the relative position of the phone input keyboard drawing and the mobile phone according to any two calibration points on the current mobile phone input keyboard drawing, and can also be based on the relative position of the other two calibration points on the input keyboard drawing of the mobile phone. Perform calibration verification to determine whether the calibration of the positional relationship between the input keyboard drawing of the mobile phone and the mobile phone is accurate, and whether calibration needs to be performed again. Specifically, the mobile phone can complete the calibration of the relative positional relationship between the mobile phone input keyboard drawing and the mobile phone according to any two calibration points on the current mobile phone input keyboard drawing, and after the calibration, through the first operating platform (ie, the input keyboard drawing of the mobile phone) The tapping signal determines the tapping point position of the tapping signal (the position in the positioning coordinate system of the mobile phone). The corresponding mobile phone inputs the key value of the input key of the keyboard drawing (for example, the input key corresponding to the character "A"). In addition, the mobile phone user can also complete the calibration of the relative position of the mobile phone input keyboard drawing and the mobile phone through two other calibration points on the input keyboard drawing of the mobile phone, and judge the mobile phone user on the first operating platform (ie, the mobile phone according to the data of the calibration). The tapping point of the tapping signal on the input keyboard drawing) Position (position in the positioning coordinate system of the mobile phone) Whether the key value of the input key on the corresponding mobile phone input keyboard drawing is consistent with the key value of the input key judged before, that is, whether it is the input key corresponding to the character "A" The key value is used to determine whether the positional relationship between the previously calibrated mobile phone and the input keyboard drawing of the mobile phone is correct.

The mobile phone judges the coordinates of the button on the mobile phone input keyboard drawing in the current positioning state by the tapping signal in the positioning coordinate system of the mobile phone, and judges the coordinates in the positioning coordinate system of the input keyboard drawing of the mobile phone according to the above coordinate transformation relationship. After that, it can be further determined that the first processing unit 32 of the mobile phone determines, according to the tapping signal on the first operating platform acquired by the acquiring module 10, the coordinates of the tapping signal in the positioning coordinate system of the mobile phone. Then, the mapping module 60 can determine the coordinates of the positioning coordinate system on the mobile phone input keyboard drawing corresponding to the tapping point position of the tapping signal according to the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone. The mapping module 60 can determine, according to the correspondence between the input button on the input keyboard drawing of the mobile phone and the coordinate of the positioning coordinate system of the input keyboard drawing of the mobile phone, the mobile phone input keyboard drawing of the tapping signal in the current placement state can be determined. The corresponding operation position (ie, the input button corresponding to the tapping point position of the tapping signal) and the key value of the input keyboard button on the mobile phone application, so as to input the current mobile phone into the tapping point of the tapping signal on the keyboard drawing The location maps to the key value of the input button on the mobile app. Specifically, the determining unit 61 in the mapping module 60 can determine the tapping signal on the mobile phone according to the location of the tapping point on the input keyboard drawing of the mobile phone and the positional relationship between the positioning coordinate system of the mobile phone and the mobile phone. Enter the location of the tap point on the keyboard drawing. After the judging unit 61 judges that the tapping signal position on the input keyboard drawing of the mobile phone is known, the mapping unit 63 can input and input the key value and input on the input keyboard map in the input method application of the mobile phone. The correspondence between the characters, the location of the tapping point of the tapping signal on the phone input keyboard drawing is mapped to the key value of the character input button of the input method applied by the mobile phone. For example, you can store your phone in your phone in advance. The coordinates (1, 3) in the positioning coordinate system of the input keyboard drawing correspond to the key value of the input key corresponding to the character "A" in the mobile phone character input application, when the mobile phone obtains the first operating platform (the input keyboard drawing of the mobile phone) After the position of the tapping point of the tapping signal is in the positioning coordinate system of the mobile phone, the tapping signal is determined according to the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone. When the coordinates of the tap point on the input keyboard drawing of the mobile phone are (1, 3), the tapping point of the tapping signal on the input keyboard drawing of the mobile phone can be mapped to the character input application of the mobile phone. The key value of the input button triggers the tapping signal as a trigger signal to trigger the corresponding response module output character "A" in the mobile phone application. For another example, as shown in FIG. 7 , if the first operating platform is a user-defined input drawing (such as an application operation diagram for playing music), and the mobile phone user pre-stores the positioning coordinate system of the input drawing in the mobile phone. In the coordinates, the coordinates of the "thumb" in Fig. 7 are (2, 1) and the key value of the input button corresponding to the note "du" is set. If the user taps the position of the tap point corresponding to the thumb, the mobile phone is knocked according to the After the signal is judged to be the position of the tapping point of the tapping signal in the positioning coordinate system of the mobile phone, the tapping point position is determined according to the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the mobile phone input drawing. The button corresponding to the "thumb" position on the input sheet of the mobile phone, that is, the key point of the button corresponding to the "thumb" corresponding to the "thumb" on the input pattern of the mobile phone, the position of the tap point can be mapped to "du" The key value of the corresponding button, and the tapping signal is a trigger signal, and the corresponding response module in the triggering mobile phone outputs a note of the corresponding volume according to the tapping intensity of the tapping signal.

In some possible implementation manners, the second operating platform of the mobile phone described in this embodiment may include an input interface of an application of the mobile phone, an input soft keyboard of the input method of the mobile phone (ie, a character input soft keyboard of the mobile phone), and the like.

As shown in Figure 7, when the first operating platform is a custom input drawing for the mobile phone user, the relative position of the input drawing and the mobile phone can also be calibrated according to the above method, and the input drawing of the mobile phone user can be customized and the corresponding mobile phone built in the mobile phone. The key value of the button of the input soft keyboard of the application is established. After connecting, and determining the position of the tapping point of the tapping signal on the input drawing of the user's custom input drawing according to the above method, the tapping point position of the tapping signal can be mapped to the second operating platform of the mobile phone (ie The operation position of the input soft keyboard of the corresponding mobile phone application built in the mobile phone (specifically, the key value of the key input to the soft keyboard).

In a specific implementation, after the mapping module 60 maps the location of the tapping point of the tapping signal on the first operating platform to the operating location of the second operating platform of the mobile phone, the generating module 70 may use the tapping signal as the second mobile phone. A trigger signal at an operating position of the operating platform generates a mobile phone input signal corresponding to the trigger signal for the mobile phone. When the first operating platform is the input keyboard drawing of the mobile phone (as shown in FIG. 6 ), the mobile phone determines that the tapping signal is on the input keyboard drawing of the mobile phone and knocks the tapping signal on the input keyboard map of the mobile phone. After the hit point location is mapped to the key value of the input soft keyboard of the mobile phone built-in input method application, the mobile phone generating module 70 can adjust the input method application of the tapping point position mapping of the tapping signal in the input method application of the mobile phone. Enter the character corresponding to the key value of the key in the soft keyboard, and output the character as the input character of the input method of the mobile phone to the input box of the mobile phone interface, that is, generate an input signal of the mobile phone. When the mobile phone input signal is generated by the mobile phone as described in this embodiment, as long as the input keyboard drawing of the mobile phone is calibrated and the position is determined, all the characters on the mobile phone input keyboard drawing are located in the positioning coordinate system of the mobile phone for the mobile phone. Known number, when the mobile phone user taps on the keyboard drawing, the mobile phone can judge the character that the mobile phone user taps according to the tapping point position of the tapping signal, and generate the character as the trigger signal of the mobile phone input signal to generate The input signal of the mobile phone can complete the conversion of the tap signal to the input signal of the mobile phone.

When the first operating platform is a custom input drawing for the mobile phone user (as shown in FIG. 7), the mobile phone user customizes the input sound corresponding to each operation position on the drawing or input characters (for example, the pitch and volume corresponding to the piano keys), when the mobile phone Judging that the position of the tap signal on the input sheet is known and mapping the tapping point position of the tap signal on the input sheet to the key value of the button on the input soft keyboard built in the mobile phone application, the mobile phone can Transfer the corresponding application The tap point of the tap signal maps the tone or volume corresponding to the key value of the button in the input soft keyboard, and outputs the corresponding music according to the tone or volume. Specifically, as long as the user-defined input drawing of the mobile phone is calibrated and the position is determined, all the characters on the input drawing in the positioning coordinate system of the mobile phone are known for the mobile phone, when the mobile phone user knocks on the drawing. When hitting, the mobile phone can judge the character that the mobile phone user taps according to the tapping point position of the tapping signal, and use the character as a trigger signal of the mobile phone input signal to generate a mobile phone input signal, and play a mobile phone user to play by himself. Music, you can complete the conversion of the tap signal to the phone's input signal.

The embodiment of the invention can map the location of the tapping point of the tapping signal on the operating platform such as the input keyboard drawing of the mobile phone or the input drawing of the mobile phone to the key value of the input soft keyboard of the input method of the mobile phone or the mobile phone. For other applications, the key value of the input soft keyboard, such as the key value of the input device on the mobile phone, and the tapping signal as a trigger signal at the operating position, used to trigger the internal application of the mobile phone, generate The input signal of the mobile phone corresponding to the trigger signal expands the generation path of the input signal of the mobile phone, improves the interest of generating the input signal of the mobile phone, and improves the user experience of the mobile phone.

FIG. 1 is a schematic structural diagram of a first embodiment of a terminal according to an embodiment of the present invention. The terminal described in this embodiment includes:

The sensor 1 00 is configured to acquire a tap signal on the first operating platform.

The memory 200 can be used to store software programs and modules, and the processor 110 executes various functional applications and data processing of the terminals by running software programs and modules stored in the memory 200. The memory 200 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application required for at least one function (such as a virtual piano application, an input method, etc.), and the like; the storage data area may be stored according to the terminal. Use the created data (such as positioning the database, etc.) and so on. Furthermore, the memory 200 may comprise a high speed random access memory, and may also comprise a non-volatile memory, such as at least one disk storage device, Flash memory devices, or other volatile solid-state storage devices.

The processor 1 1 0 is specifically configured to determine a tapping point position of the tapping signal on the first operating platform, and map a tapping point position of the tapping signal on the first operating platform to An operation position on the second operating platform, and using the tapping signal as a trigger signal on an operating position on the second operating platform to generate a terminal input signal corresponding to the trigger signal for the terminal.

The first operating platform described in this embodiment may include: a terminal body, a flat object surface on which the terminal is placed, an input keyboard drawing of the terminal, an input drawing of the end user-defined input drawing, and the like, for example, in this embodiment The first operating platform described may be the mobile phone itself, the desktop on which the mobile phone is placed, or the input keyboard drawing of the mobile phone printed by the mobile phone user and placed on the desktop of the mobile phone with the mobile phone (for example, the keyboard diagram shown in FIG. 6). , or the input device of the mobile phone, such as a mobile phone user-defined input drawing (such as the auxiliary drawing shown in FIG. 7) printed by the mobile phone user and placed on the desktop of the mobile phone with the mobile phone. In the specific implementation, the input keyboard drawing of the above mobile phone and the input drawing customized by the mobile phone user are a special type of paper, and the paper includes information such as an input keyboard picture.

When the mobile phone user uses the corresponding function of the terminal described in this embodiment, the input keyboard drawing of the mobile phone or the input drawing of the mobile phone user can be smoothly placed on the desktop where the mobile phone is placed (ie, the desktop where the mobile phone is located), and then the mobile phone The input keyboard drawing or the user-defined input drawing of the mobile phone can be tapped, and the mobile phone can obtain the input keyboard drawing of the mobile phone or the tapping signal on the input drawing of the mobile phone user through its built-in sensor 100 to process The device 1 10 generates an input signal of the mobile phone according to the tap signal. The tapping signal on the first operating platform may include: a vibration mechanical wave, a tapping time, a tapping intensity, and the like. For example, when the mobile phone user uses the input keyboard drawing of the mobile phone to input the mobile phone character, if the mobile phone is required to generate a character input signal according to the tap signal, the mobile phone function can be turned on, that is, the character input signal is generated according to the tapping signal on the first operating platform. Phone features. Mobile phone user After the above mobile phone function is activated, a tapping action can be performed on the input keyboard drawing of the mobile phone. After the mobile phone obtains the tapping signal on the input keyboard drawing of the mobile phone through its sensor 100, the processor 1 10 can be tapped according to the knocking signal. The hit signal generates an input signal for the mobile phone input method.

In a specific implementation, the mobile phone obtains a tapping signal on the input keyboard drawing (terminal input device) of the mobile phone through its built-in sensor 100, and before the processor 1 10 combines the tapping signal to generate an input signal of the mobile phone input method, First confirm the relative position of the input keyboard drawing of the mobile phone and the mobile phone, that is, it is necessary to determine the transformation relationship between the positioning coordinate system of the input keyboard drawing of the mobile phone and the positioning coordinate system of the mobile phone. Specifically, the mobile phone user needs to tap the calibration point on the input keyboard of the mobile phone to calibrate the input keyboard drawing of the mobile phone and the relative position of the mobile phone.

In some possible implementations, when determining, by the processor, the location of the tapping point of the tapping signal on the first operating platform, the processor is specifically configured to:

Locating a position coordinate of each sensor in the terminal in a positioning coordinate system of the terminal; a propagation speed of the vibration mechanical wave according to the tap signal, and a timing at which the sensor receives the vibration mechanical wave, combined with the Typing a tapping time of the signal, calculating a distance between each sensor in the terminal and a tapping point position of the tapping signal;

And obtaining, according to the position coordinates of the respective sensors in the positioning coordinate system of the terminal, the distance between the respective sensors and the tapping point position of the tapping signal, obtaining the tapping signal on the first operating platform The position of the tap point on the position in the positioning coordinate system of the terminal.

When the mobile phone obtains the tapping signal on the first operating platform through the built-in sensor 100, the processor 110 can combine the tapping signal to determine the tapping point position of the tapping signal on the first operating platform. Specifically, a positioning coordinate system of a mobile phone may be set with a specific point on the mobile phone (for example, the center of gravity of the mobile phone) as a coordinate origin, and the mobile phone may be set in a plane where the mobile phone display screen is located or a plane where the mobile phone back cover is located. Positioning the coordinate system, the direction of the bottom edge of the mobile phone is the X axis, and the direction of the side of the mobile phone is the y axis, which is used to determine the tapping point position of the tapping signal on the operating platform such as the mobile phone or the desktop on which the mobile phone is placed (ie, the tapping signal is on the mobile phone) In the positioning coordinate system Location). Specifically, a specific point on the mobile phone (for example, the center of gravity of the mobile phone) may be used to preset a coordinate axis of the positioning coordinate system for the coordinate origin, and according to the positioning coordinate system, determine the position of each sensor in the mobile phone in the positioning coordinate system, such as figure 2. After the positioning coordinate system of the mobile phone is set, the position coordinates of each sensor in the mobile phone's positioning coordinate system are determined. The processor 110 can collect the position coordinates of the respective sensors in the mobile phone in the positioning coordinate system. For example, the processor 110 can collect the position coordinates of the sensor 1, the sensor 2, the sensor 3, and the sensor 4 in the positioning coordinate system as (xl, yl), (x2, y2), (x3, y3), (x4). , y4), wherein, since the position of the built-in sensor of the mobile phone relative to the mobile phone is a fixed position, the positions of the above-mentioned respective sensors in the positioning coordinate system are all determined positions, that is, xl, yl, x2, y2, x3, y3, Both x4 and y4 are known numbers. After determining the position of the built-in sensor 1, sensor 2, sensor 3, and sensor 4 of the mobile phone, when the mobile phone user taps on the tapping point (X, y) on the first operating platform at time t, the vibration mechanical wave is generated and directed After being spread around, the processor 110 of the mobile phone can receive the time t1 of the vibration mechanical wave of the tap signal according to each sensor (the time of the vibration mechanical wave received by the sensor 1), t2 (the time of the vibration mechanical wave received by the sensor 2), t3 ( The moment of the vibration mechanical wave received by the sensor 3), 14 (the time of the vibration mechanical wave received by the sensor 4), combined with the tapping time t of the tapping signal and the propagation velocity V of the vibrating mechanical wave, can be combined with the positioning of each sensor in the mobile phone in the above-mentioned mobile phone The position coordinate in the coordinate system is multiplied by the propagation velocity of the vibration mechanical wave by the time equal to the sensing distance of the vibration mechanical wave (ie, the distance between the position of the tapping point and each sensor) to obtain the distance between each sensor and the position of the tapping point and the tapping signal. The propagation speed of the vibrating mechanical wave, the time point at which the sensor receives the vibrating mechanical wave, and the knocking letter The relationship equation of the number of tapping time points is as follows:

-^) ² +( Ί - -y) ² -t)xv y/( ^x 2 -^) ² +(y ₂ -y) ² = (,2 -t)xv

Since v, t, x, and y are unknowns in the above data, the processor 1 10 0 can process the values of the four unknowns of v, t, x, and y according to the above relationship equation. Specifically, by giving v, t, x, y a preset value, and by using an iterative calculation, the values of the four unknowns of v, t, x, and y can be processed to determine the tapping signal on the first operating platform. The position of the tap point (X, y).

In the specific implementation, since the propagation speed of the vibration mechanical wave in the specific medium is fixed, and the medium used for the mobile phone case is fixed and known (because the material of the mobile phone case is determined by the mobile phone, the mobile phone case is used for the mobile phone case) The medium is also known to be identifiable. The propagation speed of the vibrating mechanical wave on the mobile phone casing is also fixed. It can be pre-stored in the mobile phone, and the mobile phone user performs a tapping action on the mobile phone (ie, the mobile phone casing). At this time, the propagation velocity V of the vibrating mechanical wave generated by the tap on the mobile phone becomes a known amount. When the tapping point is on the mobile phone (as shown in FIG. 2), the processor 1 10 can calculate the position of the tapping point of the tapping signal on the mobile phone in the positioning coordinate system by using 3 sensors (X, y). ). If the above four sensors are used, the calculation accuracy of the position of the tapping point can be estimated according to the least squares method. In this embodiment, at least three sensors for acquiring the tapping signal are required, and at least the maximum is not limited.

As shown in Figure 3, if the tapping signal is outside the mobile phone, that is, when the first operating platform is a platform such as a desktop on which the mobile phone is placed, since the material of the desktop may be of various types (such as wood, plastic, iron, etc.), The propagation medium of the vibration mechanical wave of the hitting signal becomes an unfixed medium, and the mobile phone cannot predetermine the propagation velocity V of the vibration mechanical wave of the tapping signal on the desktop currently placed on the mobile phone, that is, the propagation velocity V of the vibration mechanical wave at this time is unknown. That is, when the tapping point of the tapping signal is on the platform such as the desktop on which the mobile phone is placed, the processor 1 10 can determine the four unknowns of v, t, x, and y according to the data obtained by the four sensors of the mobile phone. a value to determine the location of the tapping point of the tapping signal on the first operating platform. The processor 1 10 of the mobile phone judges that the vibration mechanical wave is in the current propagation medium according to the data obtained by the above sensor (ie, After the propagation speed on the desktop of the mobile phone, since the propagation velocity V of the vibration mechanical wave has been determined, the calculation of the position of the tapping point of the tapping signal on the first operating platform can be initially estimated based on the data acquired by the four sensors. Precision. Specifically, the processor 110 can obtain the 4-element second-order equation corresponding to the tapping signal of the second tap according to the above method, and can determine the propagation speed v of the vibrating mechanical wave that is known in the first tap (ie, The propagation speed of the vibrating mechanical wave on the desktop placed on the mobile phone) is substituted into the above-mentioned 4 yuan quadratic equation, and then combined with any three equations to obtain the tapping signal of the second tapping on the first operating platform. (Assume the coordinates (xl, yl) in the phone coordinate system). In addition, the processor 1 10 can also directly obtain the tapping point position 2 of the tapping signal of the second tapping on the first operating platform according to the above 4-ary equation 2 (assuming coordinates in the mobile phone coordinate system (x2) , y2 ) ) , and judge whether the coordinates of the tapping point position 2 ( x2 , y2 ) and the tapping point position 1 ( xl, yl ) coincide or whether the error is in the set error according to the tapping point position 1 obtained by the previous processing. In this context, the calculation accuracy of the tapping point position of the tapping signal on the first operating platform is estimated.

As shown in Fig. 6 and Fig. 7, when the mobile phone user performs a tapping action on the input keyboard drawing of the mobile phone or the input drawing of the mobile phone user, the tapping point of the tapping signal on the first operating platform is on the keyboard outside the mobile phone. In the figure, when not on the mobile phone, the processor 110 can determine the first operating platform (keyboard map or auxiliary drawing) in FIG. 6 or FIG. 7 according to the above method for determining the tapping point position of the tapping signal on FIG. The location of the tap point is not repeated here.

After the processor 110 determines the tapping point of the tapping signal on the first operating platform, the tapping point location can be mapped to the operating location on the second operating platform of the handset. The processor 11 0 is specifically configured to: when mapping a tapping point of the tapping signal on the first operating platform to an operating position on the second operating platform:

Matching a position of a tapping point of the tapping signal on the first operating platform in a positioning coordinate system of the terminal with a positioning database stored in the memory 200, and determining that the tapping signal is in the The second operation corresponding to the position of the tap point on the first operating platform Operating position on the platform,

Mapping a tapping point position of the tap signal on the first operating platform to an operating position on the second operating platform.

After the processor 1 1 0 determines that the tapping point position of the tapping signal on the first operating platform is known, the position of the tapping point of the tapping signal on the first operating platform in the positioning coordinate system of the mobile phone can be The positioning database pre-stored in the memory 200 is matched, and the operation position on the second operating platform of the mobile phone corresponding to the tapping point position of the tapping signal on the first operating platform is determined by database matching, and the tapping signal is The location of the tap point on the first operating platform is mapped to the operating position on the second operating platform of the mobile phone (specifically, the key value of the input button on the second platform). In a specific implementation, a perceptible tapping area of the mobile phone may be set in advance by using the positioning coordinate system of the mobile phone as a reference system. For example, a side length of the mobile phone positioning coordinate system may be set to be 2× long. Width 2Y (where the specific values of X and Y can be set at the same time as setting the positioning coordinate system of the mobile phone, or can be customized by the user of the mobile phone), the square area of the mobile phone is the perceptible area of the mobile phone, and the above-mentioned perceptible is set. The operation position on the second operating platform of the mobile phone corresponding to each tapping position in the area (specifically, the key value of the input button on the second operating platform), and storing all the corresponding relationships in the memory 200, the corresponding relationship This is the location database of the mobile phone. When the mobile phone user places the mobile phone smoothly and determines the first operating platform of the mobile phone (such as the mobile phone body or the desktop on which the mobile phone is placed), the processor 1 1 0 of the mobile phone can determine the current first operating platform according to the positioning coordinate system of the mobile phone. Perceptible area on the top (such as a specific area on the phone body or a specific area on the desktop where the phone is placed). When the mobile phone user performs a tapping action within the perceptible area of the first operating platform, the processor 1 1 0 of the mobile phone can click the tapping point of the tapping signal on the first operating platform in the positioning coordinate system. The location is matched with the location database pre-stored by the memory 200 to determine an operation location on the second operating platform corresponding to the location of the tap point on the current first operating platform. For example, in the scenario shown in Figure 2, after the mobile phone user makes a tapping action on the back of the mobile phone, the mobile phone determines the mobile phone When the tapping point position of the signal is tapped, the matching database stored in the mobile phone memory 200 can be matched to determine the virtual key on the piano playing game of the mobile phone corresponding to the tapping point position of the tap signal on the current mobile phone. a key value of a specific key, and mapping the location of the tap point to the key value of the key, and then generating a piano signal corresponding to the trigger signal for the terminal by using the trigger signal as a trigger signal of the key value of the key The input signal of the game. For example, as shown in FIG. 4, when the processor 1 10 determines that the tapping point of the tapping signal on the back of the mobile phone is a point on the upper left corner of the back of the mobile phone (the hitting point shown in FIG. 4), Then, the positioning database stored in the memory 200 of the mobile phone can be used to match that the current tap point position corresponds to the virtual key on the piano playing game of the mobile phone, and the third key from the left side of the keyboard (ie, the mapping point in FIG. 4 corresponds to The key value of the button can be used to map the tapping point of the tapping signal on the back of the phone to the key of the button on the virtual keyboard of the phone's piano playing game. Similarly, when the processor 1 1 0 determines that the tapping point position of the tapping signal is at other positions on the back of the mobile phone, it can also be matched by the positioning database stored in the memory 200 of the mobile phone to determine the tapping signal. The tap point position corresponds to the key value of the key on the virtual key. After determining that the key value of the specific key of the virtual keyboard of the piano playing game of the mobile phone corresponding to the tapping point position of the tapping signal is known, the processor 1 10 can use the tapping signal as the trigger signal of the key key value to The tapping signal triggers the virtual piano application built into the mobile phone, and the music playing manager of the mobile phone is called by the mobile phone's built-in virtual piano application to play the music corresponding to the tapping signal. The processor 1 10 0 can map the tapping point position of the tapping signal to the key value of the button on the virtual piano application on the mobile phone, and convert the tapping signal into the key value of the button on the virtual piano application of the mobile phone. a trigger signal, which is called by the virtual piano application of the mobile phone to call a sound of the tone corresponding to the tone of the specific button, and adjusts the music of the volume corresponding to the tapping intensity according to the tapping intensity of the tapping signal That is, the mobile phone can emit music of different pitches at different volume according to the tapping position of the mobile phone user and the tapping intensity. The user can adjust the pitch and volume of the music emitted by the mobile phone according to his own tapping action, and better mobilize the mobile phone user to play music through the mobile phone. The interest and passion can also trigger the inspiration of the music creation of mobile phone users, and improve the fun of signal input.

In addition, when the first operating platform is an input keyboard map of the input method of the mobile phone or a user-defined input drawing of the mobile phone, the tapping position of the tapping signal is on the input keyboard drawing of the mobile phone or the input drawing of the mobile phone user customization. In some feasible implementation manners, when determining, by the processor, the location of the tapping point of the tapping signal on the first operating platform, the processor is further configured to:

Obtaining a tap signal of the calibration point on the terminal input device, and determining a position of the calibration point on the terminal input device in the positioning coordinate system of the terminal;

And determining a relative position of the terminal input device and the terminal according to a position of the calibration point in a positioning coordinate system of the terminal and a position of the calibration point on the terminal input device.

At this time, because the input keyboard drawing of the mobile phone or the input drawing of the mobile phone user can be randomly placed by the mobile phone user, that is, the relative position of the mobile phone input keyboard drawing or the user-defined input drawing of the mobile phone and the mobile phone is uncertain. Then, it is necessary to first calibrate the input keyboard drawing of the mobile phone or the input drawing of the mobile phone user to determine the relative position of the current first operating platform and the mobile phone. When the mobile phone user needs to calibrate the relative position of the input keyboard drawing of the mobile phone and the mobile phone, the calibration points on the input keyboard drawing of the mobile phone can be tapped. After the mobile phone obtains the tapping signal on the calibration point on the input keyboard drawing of the mobile phone through the built-in sensor, it can judge the respective calibration points according to the method of judging the tapping point position of the tapping signal on the first operating platform. The position in the positioning coordinate system of the mobile phone can further determine the input keyboard drawing of the mobile phone by the position of each calibration point on the input keyboard drawing of the mobile phone (ie, the position of each calibration point in the positioning coordinate system of the input keyboard drawing) The relative position of the phone.

In the specific implementation, each character on the input keyboard map of the mobile phone and the calibration point are in the keyboard diagram. The upper position is fixed. The characters on the input keyboard drawing of the mobile phone and the coordinates of the calibration point in the positioning coordinate system of the input keyboard drawing of the mobile phone can be preset in the mobile phone application, and the mobile phone can be input into the keyboard drawing in advance. Each character and the coordinates corresponding to the calibration point (coordinates in the positioning coordinate system of the input keyboard drawing of the mobile phone) are first connected with the key value of the key input of the mobile application, and the mobile phone is input into the operation position on the keyboard drawing ( That is, the coordinates of each character and calibration point are mapped to the key value of the character input button on the mobile phone application. When the input keyboard map of the mobile phone and the mobile phone is placed on the auxiliary medium such as the desktop or the ground on which the mobile phone is placed, the relative position of the input keyboard map of the mobile phone and the mobile phone is an uncertain factor, and the mobile phone user uses the input keyboard drawing of the mobile phone as the Before the input device of the mobile phone, it is necessary to determine the relative position of the input keyboard map of the mobile phone and the mobile phone in the currently placed state, that is, the coordinate of the positioning coordinate system of the mobile phone and the coordinate of the positioning coordinate system of the input keyboard drawing of the mobile phone need to be determined. relationship.

In a specific implementation, as shown in FIG. 6, the mobile phone user determines the relative positional relationship between the mobile phone and the input keyboard drawing of the mobile phone in the currently placed state (also the coordinates on the positioning coordinate system of the mobile phone and the positioning coordinates of the input keyboard drawing of the mobile phone). When the coordinates of the system are changed, you can click the calibration button on the phone to activate the calibration function of the phone. The processor 11 0 of the mobile phone can first mark the sitting position of the positioning coordinate system of the mobile phone as ( ^x , , the positioning coordinate of the positioning coordinate system of the input keyboard diagram of the mobile phone when calibrating the relative positional relationship between the mobile phone and the mobile phone input keyboard drawing ( ^X ' J ) , the angle between the positioning coordinate system of the mobile phone and the coordinate system of the input keyboard map is recorded as ^ The angle between the X axis of the positioning coordinate system of the mobile phone and the X axis of the coordinate system of the input keyboard image is recorded as a displacement Recorded as (Δτ, y), the displacement is the coordinate of the origin of the coordinate system of the input keyboard diagram in the positioning coordinate system of the mobile phone, and the following coordinate transformation relationship is as follows:

X cos 6* sin 6* Ax X

y ― - sin 6* cos 6* y

1 0 0 1 23⁄4 Record the coordinates of each calibration point (calibration point 1, calibration point 2, calibration point 3, calibration point 4) on the input keyboard drawing of the mobile phone in the positioning coordinate system of the input keyboard diagram as i'^i), ( ₂ , Λ ₂ ), ( , Λ ₃ ), ( ₄ , Λ ₄ ). After the mobile phone user taps each calibration point on the input keyboard drawing of the mobile phone, the sensor 100 may first obtain a tapping signal on the calibration point on the input keyboard drawing of the mobile phone, and send the obtained tapping signal to the processor 110. The coordinates of the calibration point on the input keyboard drawing of the mobile phone in the mobile phone's positioning coordinate system are judged by the processor 110 as ( ' 1 ), ( ^X '^2), ( ' 3 ), (^4, ^ 4), you can list the following 4 relationships:

At this time, in the above relationship (^1' 1), ( ^X : 2'y: 2), ( ^Χ : ₃ ' Λ ₃ ), , (^2, 2), ( , 3), ( ^Χ 'Λ ₄ ) For known numbers, only 0 and (^') are unknowns, so any two of the above relations can be solved and ( , ). Once and ( , ^{Δ is} solved, the processor 1 1 0 can substitute the coordinates of each button in the input coordinate system of the mobile phone obtained by the mobile phone into the coordinate transformation relationship of the mobile phone, and obtain each The coordinates of the button on the positioning coordinate system of the input keyboard drawing of the mobile phone. The processor 1 1 0 of the mobile phone determines the coordinates of the button on the mobile phone input keyboard drawing in the current positioning state by the tapping signal in the positioning coordinate system of the mobile phone, and After determining the coordinates in the positioning coordinate system of the input keyboard drawing of the mobile phone according to the coordinate transformation relationship, the key value of the key corresponding to the coordinate in the positioning coordinate system of the input keyboard drawing of the mobile phone can be further known. The processor 1 10 determines, according to the tapping signal on the first operating platform acquired by the sensor 100, that the tapping signal is in the positioning coordinate system of the mobile phone, and then according to the positioning coordinate system of the mobile phone and the input of the mobile phone. The transformation relationship of the positioning coordinate system of the keyboard drawing determines the positioning position of the mobile phone input keyboard drawing corresponding to the tapping point position of the tapping signal The coordinates of the system. According to the correspondence between the input button on the input keyboard drawing of the mobile phone pre-stored in the memory 200 and the coordinates of the positioning coordinate system of the input keyboard drawing of the mobile phone, it can be judged that the tapping signal is The operation position on the phone input keyboard drawing in the current placement state (ie, the input button corresponding to the tapping point position of the tap signal) and the key value of the input button on the mobile phone application, to input the current mobile phone into the keyboard drawing The tapping point position of the tapping signal is mapped to the key value of the input button on the mobile phone application. For example, the coordinates (1, 3) in the positioning coordinate system of the mobile phone input keyboard drawing can be stored in the mobile phone in advance corresponding to the mobile phone character input. The key value of the button corresponding to the character "A" in the application, when the processor 1 1 0 of the mobile phone acquires the tapping point position of the tapping signal on the first operating platform (the input keyboard drawing of the mobile phone) is located in the mobile phone After the coordinates in the coordinate system, it is determined according to the transformation relationship between the positioning coordinate system of the mobile phone and the positioning coordinate system of the input keyboard drawing of the mobile phone. When the position of the hitting point of the hit signal is (1, 3) on the input keyboard drawing of the mobile phone, the tapping point position of the tapping signal on the input keyboard drawing of the mobile phone can be mapped to the character input application of the mobile phone. The key value of the input button of the character "A", and then the tapping signal is used as a trigger signal to trigger the corresponding response module output word in the mobile phone application Character "A". For another example, as shown in FIG. 7 , if the first operating platform is a user-defined input drawing (such as an application operation diagram for playing music), and the mobile phone user pre-stores the positioning coordinate system of the input drawing in the mobile phone. The coordinates including the "thumb" in Fig. 7 are (2, 1) and the corresponding note is set to "du", that is, the coordinate (2, 1) corresponds to the key value of the input button of the note "du". Then, if the user taps the position of the tap point corresponding to the thumb, the processor 110 of the mobile phone determines, according to the tapping signal, the position of the tapping point of the tapping signal in the positioning coordinate system of the mobile phone, according to the positioning coordinates of the mobile phone. The transformation relationship between the positioning coordinate system of the drawing and the mobile phone input drawing determines that the position of the tapping point on the input sheet of the mobile phone is a button corresponding to the "thumb", that is, the coordinates of the tapping point on the input sheet of the mobile phone correspond to the "thumb" The key value of the corresponding button, thereby mapping the location of the tap point to the key value of the button corresponding to "du", and the tapping signal is a trigger signal, triggering the corresponding response module in the mobile phone according to the tapping signal Percussion intensity of the output volume of the corresponding note.

In addition, the processor 11 0 can complete the calibration of the relative position of the mobile phone input keyboard drawing and the mobile phone according to any two calibration points on the current mobile phone input keyboard drawing, and can also be based on the other two calibration points on the input keyboard drawing of the mobile phone and the mobile phone.

The tapping signal on the keyboard drawing determines the tapping point position of the tapping signal (the position in the positioning coordinate system of the mobile phone). The corresponding input key of the input key of the mobile phone drawing (for example, the input key corresponding to the character "A") value. In addition, the processor 1 10 can also complete the calibration of the relative position of the mobile phone input keyboard drawing and the mobile phone through two other calibration points on the input keyboard drawing of the mobile phone, and judge the mobile phone user on the first operating platform according to the data of the calibration ( That is, the tapping point position of the tapping signal on the input keyboard drawing of the mobile phone (the position in the positioning coordinate system of the mobile phone) Whether the key value of the input key on the input keyboard drawing is consistent with the key value of the input key previously determined, that is, whether it is the key value of the input key corresponding to the character "A", thereby judging the previously calibrated mobile phone and the mobile phone Enter the correct positional relationship of the keyboard drawing.

After the position calibration of the input keyboard drawing of the mobile phone and the mobile phone is accurate, the processor 110 can combine the operation position of the input keyboard map preset in the input method application of the mobile phone with the operation position of the second operating platform of the mobile phone. The correspondence between the input keyboard drawing of the mobile phone and the operating position of the second operating platform of the mobile phone is determined.
