The memory 102 is configured to store application code that executes the above solution, and is controlled by the processor 101 for execution. The processor 101 is configured to execute application code stored in the memory 102.

The code stored in the memory 102 shown in FIG. 1 can perform a key generation method of an input device provided by an embodiment of the present invention, such as detecting a touch signal of a flexible touch panel of a user's N finger touch input device, where N is greater than Or an integer equal to 1; determining a position where the N fingers are located according to the touch signals of the N fingers; and generating a virtual key position according to the position where the N fingers are located.

Consistent with the technical solution described above, as a specific embodiment, FIG. 2 is a schematic flow chart of a key generation method including a specific execution process of an input device. Although the key generation method described herein is performed based on the input device 100 shown in FIG. 1, it should be noted that the specific operating environment of the key generation method disclosed in the embodiment of the present invention is not limited to the input device 100 described above.

As shown in FIG. 2, the key generation method of the input device disclosed in the method embodiment of the present invention specifically includes the following steps:

S201. The input device detects a touch signal of the flexible touch panel of the N finger touch input device of the user, where N is an integer greater than 1 or equal to 1.

S202. The input device determines, according to the touch signals of the N fingers, a position where the N fingers are located.

S203. The input device generates a virtual key position according to the position where the N fingers are located.

Optionally, for example, referring to FIG. 3, the specific implementation manner of the foregoing step S203 is:

S203-a. The input device acquires the identification information of the N fingers.

S203-b. The input device generates W first key positions corresponding to the N fingers according to the mapping relationship between the identification information of the finger and the key position and the position where the N fingers are located, where W is greater than or equal to 1. Integer.

For example, the flexible touch panel of the input device includes a fingerprint recognition module. When the user's N fingers (assuming ten fingers) touch the flexible touch panel of the input device, the fingerprint recognition module can acquire the identifier of the N fingers. Information (such as fingerprint information), the input device can know which finger of the user is the N fingers according to the fingerprint information of the N fingers, and finally the input device according to the fingerprint information of the N fingers and the mapping relationship between the finger fingerprint information and the virtual key position, A virtual key corresponding to N fingers is generated at a position where the N fingers are located. The fingerprint identification module may be an existing capacitive identification module, or an image recognition module, or other types of identification modules, which are not limited herein. In addition, the identification information may also be electronic identification information. For example, the user can wear gloves on the hand, and the gloves have different electronic identifiers at positions corresponding to each finger. For example, the electronic index of the index finger is 1, the electronic identifier of the thumb is 2, and the electronic identification of the little finger is 3. The electronic identification can include a position and identification signal generator, and the processor of the flexible touch panel is also coupled to the receiver. The receiver receives the location information and the identification information of each electronic identifier, thereby determining which finger the finger that is in contact with the flexible touch panel belongs to and the position of the touch.

Optionally, for example, the specific implementation manner of step S203 is:

The input device generates W first key positions corresponding to the N fingers according to the position where the N fingers are located.

For example, the user touches the N fingers of the two hands (assuming ten fingers) to the flexible touchpad of the input device, and the flexible touchpad of the input device detects ten touch signals of ten fingers touching the flexible touchpad, ten touches. The signal corresponds to ten fingers one by one. The input device can determine ten positions where ten fingers are located according to ten touch signals, ten positions correspond to ten fingers one by one, and finally the input device is based on ten fingers of ten fingers. The location generates a plurality of virtual key positions, wherein the plurality of virtual key positions may be ten or nine, and may be other numbers, etc., which are not limited by the present invention. For example, the generated virtual space corresponds to the position of two thumbs at the same time, ASDFHJKL corresponds to the position of the other eight fingers of the hands, and the other virtual keys are generated around the nine virtual keys. Of course, you can also generate 2 spacebars to correspond to two thumbs. Further, if N is less than 10, the virtual key position can also be generated according to the position of the finger. For example, when N=7, it means that the user's hands are in contact with the flexible touchpad. The input device will determine which touch points belong to the left hand according to the position and area of the contact point, which These touch points belong to the right hand, and then calculate which positions of the remaining 3 untouched fingers should be located on the flexible touchpad, thereby generating 10 virtual keys for each finger. When N=1, the user can set in advance in the input device, set a finger as a standard reference finger (for example, the index finger is set as the reference finger of the letter F), and store the preset of all the letters in the input device. The key positions are arranged. When the user is in use, the index finger only needs to be in contact with the flexible touchpad. After the input device detects the contact of the index finger, the contact position is set to the position of the key F, and the rest is generated according to the stored other alphabetic key positions. Virtual Key. In this way, all virtual keys can be generated with only one finger.

Optionally, after the step S203, the method shown in FIG. 1 further includes:

The input device generates M second key positions corresponding to the N fingers according to the touch position where the N fingers are located, and the M is an integer greater than or equal to 1.

Optionally, the second key position is generated according to the position of the first key position adjacent to the second key position, regardless of the positions of the other first key positions.

For example, suppose N fingers are ten fingers, and ten fingers from left to right are left hand little finger, left hand ring finger, left middle finger, left index finger, left thumb, right thumb, right index finger, right middle finger, right hand ring finger, The right hand little finger, the input device generates W first key positions corresponding to ten fingers respectively at the touch position where ten fingers are located, wherein W may be an integer equal to N or an integer not equal to N, such as The first key position of the left hand little finger, the left hand ring finger, the left middle finger, the left hand index finger, the right hand index finger, the right middle finger, the right hand ring finger, and the right hand little finger is the ASDFHJKL key, and the first key corresponding to the left thumb and the right thumb is the space key. Bit. Of course, the first key position corresponding to the left thumb and the right thumb may be the first space key and the second space key respectively. Further, after the W first key positions are identified, the remaining second key positions are generated around each of the recognized touch positions (the second key position is a key position generated according to the first key position). The generation position of the second key position is determined according to the first key position around it, and is not affected by the other first key positions. For example, if the first key position generated by the ring finger position is S, then the second key position generated around S is W and X, and the first key position generated by the middle finger position is D, then the second key position generated around D is E. And C. The generation positions of W and X are only related to S, and are not related to D. The generation positions of E and C are only related to D, and are not related to S. That is, if the distance between D and S is very far, the distance between the generated W and E will also become farther. Similarly, if the distance between D and S is very close, then the spacing between W and E will be very close. This way of independently generating nearby keys based on each touch position makes the input more flexible, for the hand The shape and size of the different sizes can be used to adaptively adjust the key position. Specifically, if the hand shape is small and the distance between the fingers is also small, the pitch of the generated second key position will also become smaller, and vice versa.

For another example, as shown in FIG. 4, the top, bottom, and left keys are generated around the position of the left hand little finger, and the upper and lower keys are generated around the position of the left hand ring finger, and the upper and lower keys are generated around the position of the left middle finger. The top, bottom, and right keys are generated around the position of the index finger of the left hand. The right hand key is similar. By controlling each finger up to 4 key positions (the little finger and the index finger control 4 key positions, the thumb controls 1 key position, the other 2 fingers control 3 key positions), and the key positions are reasonably distributed in the up, down, left, and right. The position allows you to quickly find the letters you need while typing, thus increasing the typing speed. In particular, the key layout of the present invention is different from the key layout of a commonly used physical keyboard, in particular, the key position near the index finger and the key position of the right hand are different, and the purpose is to facilitate the user to perform blind typing. Because there is no key mark on the flexible touch panel, if it is arranged like the key of the physical keyboard, the index finger needs to control at least 5 key positions at the same time. For example, the left index finger should control RTFGV and even B. For the invisible key of the flexible touchpad, it is difficult to accurately press the 6 key positions (for example, to distinguish which position above the F is R or T, but because the key position is invisible, it is impossible to distinguish R and Where is the boundary of T). Therefore, the present invention uses an unobtrusive key layout such that each of the first key positions is distributed with up to three second key positions controlled by the same finger, so that the same finger can pass through the middle, the upper, the lower, and the left ( Or right) to make a distinction without confusion. Therefore, this key layout is especially suitable for situations where the key is not visible.

Optionally, for example, referring to FIG. 5, after the input device generates the W first key positions corresponding to the N fingers, the method further includes:

S203-c. The input device detects that one of the N fingers touches a touch area of the flexible touch panel, and the touch area is a touch area other than the first key position.

S203-d: The input device determines the input content corresponding to the touch area according to the direction of the touch area corresponding to the first key position corresponding to the one of the fingers.

For example, after the W first key positions are recognized, the specific position of the second key position may not be generated, but the letter of the finger relative to the first key position may be directly determined according to the position of the first key position when typing. Specifically, according to the previous key layout, the second key position is distributed at positions corresponding to the upper, lower, left, and right of the first key position. Therefore, after the first key position is determined, the second key may be Bit along the same The direction is infinitely expanded, that is, as long as it is above the first key position, it will be counted as a second key position, as long as it is to the left of the same key position, it will be counted as another second key position, regardless of the distance first. How far is the key, and so on. This type of key setting makes the input more flexible, without having to be constrained by which precise position the second key position is, as long as the touch is recognized along the same direction. For example, for the S key, as long as the same finger touches the S key, no matter how far the touch distance is from the S key, it will be recognized as W. In other words, in this mode, any touch area in a certain direction from the boundary of the first key position is the second key position.

Optionally, after the step S203, the method further includes: if the touch signal of the flexible touch panel is not detected by the at least one finger within the preset duration, the input device eliminates the virtual key.

Optionally, after the step S203, the method further includes: if the touch signal of the flexible touch panel is not detected by the palm within the preset duration, the input device eliminates the virtual key position.

Optionally, after the input device eliminates the virtual key position, the method further includes: the input device prompts the user by the prompting device that the virtual key position of the input device is eliminated.

For example, when the user needs to pause while typing, all the fingers may leave the flexible touchpad of the input device, and when the typing continues, since the flexible touch panel has no button logo, the original first cannot be accurately found. The position of the key causes confusion in typing. Therefore, it can be set that the flexible touch panel does not detect any touch operation of the user within a preset duration (for example, 5 seconds, 10 seconds, etc.) (ie, when the user's hands are all away), the input device automatically eliminates the arrangement of the keys. At this time, the user needs to continue typing, and then the ten fingers can be placed on the flexible touch panel for re-recognition to generate a key position. Of course, it is also possible to set the key arrangement to be eliminated as soon as all of the user's fingers have left the flexible touchpad. Further, sometimes the user just leaves ten fingers and the palm portion remains on the flexible touchpad. In this case, the user can still find the original key position by the positioning of the palm, so if the flexible touchpad detects that there is still If the palm exists, the key position will not be eliminated. The input device automatically eliminates the arrangement of the keys only when the ten fingers and the palms are away from the flexible touchpad for a predetermined length of time (eg, 5 seconds, 10 seconds, etc.). Further, the input device can also be connected with a prompting device (such as an LED light). When the key position is arranged, the LED light displays a green light, and when the key position is eliminated, the LED light displays a red light, which is convenient for the user to distinguish.

Optionally, for example, referring to FIG. 6, the virtual key bit includes a function virtual key bit. After the step S203, the method further includes:

S204. If the first touch operation of the user's finger for the virtual key position of the function is detected, the input device is loaded. Switch from letter input mode to gesture recognition mode.

S205. The input device detects a touch gesture input by the user on the flexible touch panel, and determines a character corresponding to the touch gesture.

S206. After the user inputs the character, the input device switches from the gesture recognition mode to the letter input mode.

Optionally, after the step S203, the method further includes: if detecting a sliding operation of the preset finger in the preset area of the flexible touch panel, the input device determines a character corresponding to the sliding direction of the sliding operation.

Optionally, for example, referring to FIG. 7, the virtual key bit includes a function virtual key bit. After the step S203, the method further includes:

S207. If a second touch operation of the user's finger for the function virtual key is detected, the input device switches the W first key positions corresponding to the N fingers from the letter key position to the numeric key position.

S208. After the user inputs the number, the input device switches the W first key positions corresponding to the N fingers from the numeric key position to the letter key position.

For example, the above button layout only considers letters. If you need to input symbols, you can do this by giving the second key to the right of the right hand little finger. The second key position reserved on the right side of the right hand little finger is a function switching key. When the key is touched, the input device will activate the gesture recognition mode, and the user can draw a corresponding position on the flexible touch panel through the right index finger or the right thumb. Symbols, numbers (such as commas, periods, asterisks, etc.), after the user draws the symbol, the input device will automatically switch back to the letter input mode. Of course, in the gesture input mode, except for the finger to draw the symbol, the other fingers do not need to move at all, so the corresponding first and second keys can remain unchanged, but the first area around the finger of the finger to be drawn, The second key is removed and recovered after the symbol is drawn. For another example, you can use the two free thumbs and do not need to use the right hand little finger to switch functions. Specifically, it is set to correspond to different symbols in the four directions of up, down, left, and right of each thumb, such as a comma on the left thumb and a period on the left, a question mark on the left, an asterisk on the right, and the like. Further, when it is required to input a number, the function switching key can be touched, and the ten first key positions corresponding to the ten fingers are respectively turned into ten numeric key positions. After the input is completed, press the function touch key to switch back to the letter input mode.

Optionally, after the step S203, the method further includes: if it is detected that the touch time of the user's finger touching the virtual key is greater than the third preset duration, the content is not output.

For example, some fingers in the typing process will always be placed at the position of the first key position as a support, but in fact, this part of the finger does not have the intention of outputting letters, in order to avoid confusion caused by the touch of the part of the finger, the input device It can be set to count only the touch actions whose touch time is less than or equal to the third preset time length (such as 1 second, 2 seconds, 3 seconds or other values), that is, if the time spent in a key position exceeds 2 seconds, Then this touch will not be considered a typing action.

Optionally, the display connected to the input device can display the content input by the user, and the display manner can be: 1. directly displaying the content of the blind hit (ie, the content output by the user by tapping the virtual key position); 2. displaying the virtual keyboard. The key position (such as the first key position, or the first key position and the second key position), and simultaneously displays the content of the blind hit.

Preferably, the above display manner mainly adopts the second scheme described above, so as to facilitate the user to recognize the contact key.
