Detailed Description
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
Example one
The embodiment of the invention provides an information processing method which is applied to electronic equipment. In particular, the electronic device in this embodiment includes a touch unit, wherein the touch unit includes a touch display unit and a touch detection unit, wherein, for example, the touch display unit is typically represented by a touch screen, and the touch detection unit is typically represented by a touch pad, and the touch display unit is actually a device that combines the touch pad and the display unit, such as a display screen. Specifically, the electronic device in this embodiment may be a smart phone including a touch screen, a personal computer, a notebook computer, a netbook computer (netbook), a tablet computer, a desktop computer, a smart television, and the like.
The functions implemented by the information processing method provided in this embodiment may be implemented by a processor in the electronic device calling a program code, and certainly, the program code may be stored in a computer storage medium.
Fig. 1-2 are schematic diagrams illustrating a flow of implementing an information processing method according to an embodiment of the present invention, as shown in fig. 1-2, the information processing method includes:
here, since the touch unit has various forms, the operation body corresponding to the touch unit is also different, but it should be noted that although there is a difference in the principle that the touch unit senses the operation body, the implementation of the present embodiment is not affected. Among the various detecting units, a capacitive touch screen (capacitive touch screen) is the most widely used touch display unit due to its advantages of good definition, sensitivity, and support for multi-touch technology, and in this embodiment and the following embodiments, the capacitive touch screen will be taken as an example to describe the embodiments of the present invention.
Here, the operation body refers to a human body or an object that can be sensed by the touch unit, for example, in the case of a capacitive touch screen, the operation body may be a human body having a biological characteristic such as a palm, a wrist, a finger, a skin, and the like, and may also be a stylus that can be sensed by the capacitive touch screen.
Here, the touch operation includes a contact touch operation and a proximity (spaced) touch operation, where, for a general touch unit (first type of touch unit), an operation body needs to be in contact with the touch unit to recognize the operation of the operation body; however, for some touch units, the operation body is not required to directly contact with the touch unit (second type of touch unit), as shown in fig. 1-3, the diagram b in fig. 1-3 is the left side view of the diagram a in fig. 1-3, when a user uses such a touch screen 32, as long as the distance 33 between the finger 31 of the user and the touch screen 32 is within the range that can be sensed by the touch screen 32, the touch screen 32 can position the finger 31, thereby obtaining the touch operation of the user. Because the second type of touch unit can sense the finger without direct contact, cross infection can be well avoided, and the touch screen is clean and sanitary.
Here, for an electronic device having a touch unit, the electronic device generally further includes a touch chip (IC), and the touch chip includes a Micro Controller Unit (MCU) for receiving a Digital signal after being processed by an Analog/Digital converter (a/D) and processing the Digital signal into a touch signal according to a predetermined program; and then the microprocessor in the touch chip sends the touch signal to a main processor of the electronic equipment. It can be seen that the function of the microprocessor on the touch chip is to process raw data into a touch signal, generally speaking, the function of the microprocessor is performed by a hardware manufacturer of the touch screen, and the hardware manufacturer of each touch screen has different processing methods for raw data. Taking a capacitive touch screen as an example to illustrate a processing method, a microprocessor on a touch chip obtains the capacitance of a changed continuous area, if the area of the continuous area is smaller, the central position of the area is directly taken as the position of a touch point to be reported, and a touch signal with position information is obtained; if the continuous area is large, the continuous area is resolved into one touch point or a plurality of touch points (signals), wherein the one touch point carries one corresponding position information, and the plurality of touch points carry a plurality of corresponding position information.
In this embodiment, the original data refers to data that is not processed by the touch chip, and may be data output by an analog-to-digital converter, for example.
102, processing the original data of the touch event to obtain a sensing area, wherein the sensing area is used for describing an area range of the touch detection unit sensing the operation body;
here, for the first type of touch unit described above, the sensing regions are as regions 41 to 47 (white) in fig. 1 to 4. FIGS. 1-4 are an example of a scenario where a user, using a virtual keyboard on a touch screen, rests their palm on the screen, where the fingers, palm portion connecting the thumb and little finger, of the larger area, part of the wrist, that may be used for normal tapping, are in contact with the touch screen; in other words, the regions 41 to 47 may be generated by the contact of the fingers, the palm portion of the hand connecting the thumb and the little finger, and a portion of the wrist with the touch screen, which are used in normal tapping. As can be seen from fig. 1-4, when a hand is applied to the touch screen, the capacitance values of the touch screen contact areas 41-47 change; what is different is that the capacitance value change on the areas 41 to 47 where the hand is in contact with the touch screen is of one type (i.e. sensing area), and the capacitance value change on the areas where the hand is not in contact with the touch screen is of another type, corresponding to the sensing area, the areas where the hand is not in contact can be called non-sensing areas, and the change value of the capacitance (which can be understood as raw data in the present embodiment) on the whole screen is output to the processor after analog-to-digital conversion, and in the present embodiment, the processor processes the change value of the capacitance into the sensing areas as shown in fig. 1 to 4. The prior art comprises the following treatment processes: the change value of the capacitance is output to a microprocessor on the touch chip after analog-to-digital conversion, and is processed into a touch signal by the microprocessor.
Here, for the second type of touch unit, the sensing area is not different from that shown in fig. 1 to 4, because, as long as the distance between the hand and the touch unit is within the range that the second type of touch unit can sense, the capacitance value changes in one type in the area (sensing area) on the second type of touch unit within the sensing range, and the capacitance value changes in another type in the area (non-sensing area) on the second type of touch unit outside the sensing range, so that the processing procedure of step 102 is not different from that of the first type of touch unit only needing to approach for sensing.
here, the characteristic parameters may include parameters such as an area, a positional relationship, a circumscribed rectangle, and a main axis direction.
And 104, determining the effectiveness of the sensing area according to the characteristic parameters of the sensing area.
Here, step 104, determining the validity of the sensing region according to the characteristic parameter of the sensing region, includes: judging whether the sensing area is effective or not according to the characteristic parameters of the sensing area, and if so, recording an input object corresponding to the effective sensing area; and if not, ignoring the input object corresponding to the invalid sensing area.
Here, the input object may include characters on a virtual keyboard, and may also include other objects, such as navigation on a web portal, news headlines; each video window on the video website; navigation and news titles on the portal website are all linked, the video window is also linked, and when a user clicks the news title, the electronic equipment displays news corresponding to the news title. This click is also considered as an input object by the user.
The technical solution provided by the embodiment of the present invention can be used in the following scenarios, as described in the foregoing background art, when the virtual keyboard is called out, only the sensing area corresponding to the finger can be regarded as the effective area, and the sensing area corresponding to the palm and the wrist is invalid. Referring to fig. 1-4 and 1-5, by calculating the characteristic parameters of the sensing regions, the sensing regions 42 to 46 are judged to be valid and the sensing regions 41 and 47 are judged to be invalid according to the characteristic parameters, and as can be seen from fig. 1-4, the sensing regions 42 to 46 correspond to finger regions and the sensing regions 41 and 47 correspond to palms.
In the embodiment of the invention, the original data of a touch event is obtained, wherein the touch event is the touch operation of an operating body on a touch detection unit; processing the original data of the touch event to obtain a sensing area; the sensing area is used for describing an area range of the touch detection unit sensing the operation body; calculating characteristic parameters of the sensing area; determining the effectiveness of the sensing region according to the characteristic parameters of the sensing region; therefore, the technical scheme provided by the embodiment of the invention is a false touch judgment method based on the original data of the touch screen; the scheme firstly takes raw data (raw data) of the touch screen instead of a single touch point signal; and identifying an effective sensing area and an ineffective sensing area according to the individual geometric characteristics (characteristic parameters) of the original data so as to distinguish a false touch signal from a normal finger signal and further reject the false touch caused by the fact that an abnormal finger touches a screen during user operation.
In the related technology, in order to distinguish a false touch signal from a normal finger signal, two schemes are provided, wherein the first technical scheme is that in order to distinguish the false touch signal from the normal finger signal, a touch screen signal can be received only in a keyboard key area, and a signal is not received in an area supported by a hand; the first technical solution in the related art has disadvantages in that: the flexibility is poor, and the problem is not solved fundamentally; for example, a false touch in the keyboard area is inevitable when the user's hand inadvertently makes a touch. The technical solution provided by the present embodiment and the first technical solution have the following advantages: the scheme provided by the embodiment has no fixed area limitation, and the error touch at any position on the whole touch screen can be rejected.
The second technical solution in the related art distinguishes the false touch signal from the normal finger signal according to the difference between the stylus signal and the signal generated by touching the touch screen with the hand. The second technical solution in the related art has the following disadvantages: a special stylus is required and will fail if the stylus produces the same signal as if the hand were touching the touch screen or if the user is inputting directly with a finger instead of the stylus. The technical solutions provided by the present embodiment and the second technical solution have the following advantages: the technical scheme of the embodiment does not depend on the type of the touch type, a user does not need to use a special touch pen, the user can directly operate on the touch screen by using a finger, and the mistaken touch can be rejected at the moment.

Fig. 2-1 is a schematic flow chart of an implementation of a second information processing method according to an embodiment of the present invention, as shown in fig. 2-1, the information processing method includes:
here, when the sensing node is a capacitive touch screen, the value derived by the sensing node is the capacitance value and the coordinate of the capacitance.
here, in the implementation process of step 202, it is determined whether the values of two adjacent sensing nodes are of the same type, if the values of the two sensing nodes are of the same type, the two sensing nodes are connected to form a region, and if the values of the two sensing nodes are different, the two sensing nodes are not connected together. After step 202, an area is formed on the whole touch unit, that is, adjacent areas with the same numerical type are formed into independent areas, and when the numerical type includes two types, the area type formed on the touch unit includes two types; when the numerical type includes N types, where N is an integer of 2 or more, the type of the area formed on the touch unit also includes N types. In the following, a capacitive touch screen is taken as an example, when an operating body touches the capacitive touch screen, capacitance values of sensing nodes of the touch screen change, capacitance values of some sensing nodes do not change (assumed to be 0), capacitance values of some sensing nodes become negative numbers, capacitance values of some sensing nodes become positive numbers, wherein the sensing node whose capacitance value changes to negative or positive is called the node whose capacitance value changes, FIG. 2-2 is a schematic diagram of the original data in the second embodiment of the present invention, the graph b in fig. 2-2 is an enlarged schematic diagram of the area 50 in the graph a in fig. 2-2, and it can be seen from the graph b in fig. 2-2 that the capacitance value of the capacitive sensing node in the area 52 is unchanged, the capacitance value of the capacitive sensing node in the area 53 is a positive number, and the capacitance values of the capacitive sensing nodes in the areas 51 and 54 are negative numbers. After processing fig. 2-2 through step 202, the resulting sensing regions can be referred to as regions 41 through 47 shown in fig. 1-4.
Here, the steps 203 to 204 correspond to the steps 103 to 104 in the first embodiment, respectively, and therefore, those skilled in the art can understand the steps 203 to 204 with reference to the first embodiment, and details are not repeated herein for brevity.
EXAMPLE III
Based on the foregoing embodiments, an embodiment of the present invention provides an information processing method, which is applied to an electronic device. In particular, the electronic device in the present embodiment includes one touch unit. Specifically, the electronic device in this embodiment may be a smart phone, a personal computer, a notebook computer, a netbook computer (netbook), a tablet computer, a desktop computer, a smart television, and the like, which include the touch unit.
The functions implemented by the information processing method provided in this embodiment may be implemented by a processor in the electronic device calling a program code, and certainly, the program code may be stored in a computer storage medium.
Fig. 3 is a schematic flow chart of an implementation of a third information processing method according to an embodiment of the present invention, and as shown in fig. 3, the information processing method includes:
here, the steps 301 to 302 correspond to the steps 101 to 102 in the first embodiment, respectively, and therefore, a person skilled in the art can understand the steps 101 to 102 with reference to the first embodiment, and details are not described herein for brevity.
here, the area of the sensing region may be represented by the number of occupied sensing nodes, for example, in the b diagram of fig. 2-2, the sensing region 53 occupies 20 sensing nodes, the capacitance value of each sensing node is an integer and is expressed in a 16-ary manner, and the capacitance value of a certain node is, for example, a numerical value such as 3b, a2, and the like. By analogy, the areas of sensing regions 41 to 47 in fig. 1-4 can be calculated, for example, the area of sensing region 41 is 29 sensing nodes, the area of sensing region 42 is 4 sensing nodes, the area of sensing region 43 is 4 sensing nodes, the area of sensing region 44 is 4 sensing nodes, the area of sensing region 45 is 4 sensing nodes, the area of sensing region 46 is 9 sensing nodes, and the area of sensing region 47 is 17 sensing nodes.
here, the first condition may generally refer to any condition related to the area of the sensing region, for example, a threshold value related to the area may be set, or a range related to the area may be set.
Here, continuing with the example in step 303, as can be seen from step 303, the area (29 or 17) of the sensing region corresponding to the palm is much larger than the area (4 to 9) of the sensing region corresponding to the finger, if the first condition is an area threshold, for example, the first condition may set the area threshold to be 10 to 16, taking the area threshold to be 10 as an example, and if the area of the sensing region is smaller than 10, the sensing region may be determined to be valid; the sensing region is determined to be invalid if the area of the sensing region is greater than 10.
If the first condition is set as the area range, specifically, the first condition may set the area range to 3 to 10, and if the area of the sensing region is within the area range of 3 to 10, the sensing region is determined to be valid, for example, the sensing regions 42 to 46 may be determined to be valid, whereas if the area of the sensing region is no longer within the area range, the sensing region is determined to be invalid. Of course, the first condition may also set the area to be in the range of 15 to 35, and if the area of the sensing region is within the area range of 15 to 35, it is determined that the sensing region is invalid, for example, the sensing regions 41 and 47 may be determined to be invalid, whereas if the area of the sensing region is not within the area range of 15 to 35, it is determined that the sensing region is valid, for example, the sensing regions 42 to 46 are valid.
In the embodiment of the present invention, when the characteristic parameter is an area, the above-mentioned steps 304 to 305 actually provide a method for implementing the step 104 "determining the validity of the sensing region according to the characteristic parameter of the sensing region".
Example four
Based on the foregoing embodiments, an embodiment of the present invention provides an information processing method, which is applied to an electronic device. In particular, the electronic device in the present embodiment includes one touch unit. Specifically, the electronic device in this embodiment may be a smart phone, a personal computer, a notebook computer, a netbook computer (netbook), a tablet computer, a desktop computer, a smart television, and the like, which include the touch unit.
The functions implemented by the information processing method provided in this embodiment may be implemented by a processor in the electronic device calling a program code, and certainly, the program code may be stored in a computer storage medium.
Fig. 4-1 is a schematic flow chart of an implementation of a four-information processing method according to an embodiment of the present invention, as shown in fig. 4-1, the information processing method includes:
here, the operation body refers to a human body or an object that can be sensed by the touch unit, for example, in the case of a capacitive touch screen, the operation body may be a human body having a biological characteristic such as a palm, a wrist, a finger, a skin, and the like, and may also be a stylus that can be sensed by the capacitive touch screen.
Here, the raw data refers to data that is not processed by the touch chip, and may be data output through an analog-to-digital converter, for example.
here, the steps 401 to 403 correspond to the steps 101 to 103 in the first embodiment, respectively, and therefore, a person skilled in the art can understand the steps 401 to 403 with reference to the first embodiment, and details are not described herein for brevity.
here, the touch model is an integral structure formed by the sensing units when the operating body is in contact with the touch units, such as a hand shape (touch model) formed by the sensing units 41 to 47 shown in fig. 1 to 4, and in the process of specific application, the hand shape shown in fig. 1 to 4 is actually an ideal contact model, and actually, the contact model may have other types due to the problem of the operation habit of people, such as the c diagram of fig. 4 to 2; the contact model may also have only the parts of fig. 1-4, such as the a-and b-diagrams of fig. 4-2, where the dotted line part represents the non-contact, in other words, the dotted line part represents the non-sensing region.
Here, step 405, determining the validity of the sensing region from the first touch model, comprises: determining sensing regions in the first contact model that represent fingers to be valid, and determining sensing regions in the first touch model other than the sensing regions that represent fingers to be invalid.
In the embodiment, raw data (raw data) of the touch screen is taken first, instead of a single touch point signal; according to the individual geometric features of the original data and the relative position relationship (characteristic parameters) of the space, a certain user contact model is analyzed, extracted and formed, so that the difference between the false touch signal and the normal finger signal is identified and distinguished, and the false touch brought by the fact that the user touches the screen by an abnormal finger point during operation is rejected. It follows that the validity or invalidity of the sensing region is determined according to the overall structure (first touch model) formed by the sensing units, so that in the determination process, the sensing region representing the finger in the first touch model can be determined; the remaining sensing regions may be determined to be invalid. As can be seen from the above description, the technical solution provided by this embodiment is actually a determination method based on such integrity, and therefore, has higher accuracy.
In this embodiment of the present invention, step 404, establishing a first touch model according to the area of the sensing region and the position of the sensing region includes:
step 4041, acquiring an area and a position of a first sensing region, where the first sensing region is a sensing region with a largest area;
here, there are many methods for calculating the area of the sensing region, and it is preferable that the number of sensing nodes represents the area of the sensing region, and the sensing nodes can be understood as one pixel point and thus can be used to represent the area of the sensing region. When a plurality of sensing regions having equal areas exist, one sensing region may be acquired as a first sensing region according to a preset rule; a person skilled in the art may set a preset rule according to an actual situation, for example, obtain the positions of a plurality of sensing regions with equal areas, and use the sensing region located at the lower left or lower right as a first sensing region; the reason why the lower left or lower right sensing region is used as the first sensing region is that the lower left or lower right sensing region is generally a palm region connected to the thumb. Note that in step 4041, a sensing area is actually determined, which corresponds to the palm area connected to the thumb; only in step 4041 is the palm region connected to the thumb the sensing region with the largest area.
Here, the reason why the sensing region having the largest area is used as the palm region connected to the thumb is that the palm portion area is generally larger than the area of the finger region, and after the palm is determined, the hand shape is substantially determined. Therefore, the determination may be started by picking the largest sensing region (hereinafter referred to as a master block) from among sensing regions having an area larger than a certain threshold T1.
Step 4042, determining the main axis direction of the first sensing region according to the area and position of the first sensing region;
here, step 4042 determines the primary axis direction of the first sensing region from the area and position of the first sensing region, including: and calculating a circumscribed rectangle of the first sensing region according to the area and the position of the first sensing region, and then determining the main axis direction of the first sensing region according to the circumscribed rectangle of the first sensing region.
In step 4042, the aspect ratio of the main block may also be considered; as shown in fig. 4-2, if the length and the width are close, it is considered that the model may be a palm front contact model, and a palm front contact hand type (abbreviated as type1) is formed by flatly placing the plane where the palm is located on the touch screen; if the aspect ratio is very different, the area of the main block and the area of the circumscribed rectangle are further considered. If the area of the block is small and the ratio of the area of the circumscribed rectangle to the actual area of the block is greater than the threshold T2, it can be considered that the palm-side portion of the palm contacts the screen (type 2), i.e. the plane where the palm is located is perpendicular to the touch screen; if the tile area is large and the ratio of the circumscribed rectangle area to the actual tile area is smaller than the threshold T3, it can be considered as a palm front touch screen and a lower half palm touch screen (type 3).
Step 4043, determining a palm region of the first touch model according to a main axis direction of the first sensing region;
step 4044, acquiring a second sensing region excluding the sensing regions constituting the palm region;
step 4045, determining a distance between a center of the second sensing region and a center of the palm region;
step 4046, determining a sensing area farthest from the palm area as a finger area;
step 4047, a first touch model is established according to the palm area and the finger area.
In the above-described steps 4042 to 4047, the stub 4042 is divided into three types of type1, type2, and type3 to describe how the first touch model is established.
1) For type1
After the main shaft direction of the main block is determined, searching whether other sensing areas exist in the range of two sides with the included angle of the main shaft direction being a threshold value T4, such as the sensing areas marked by the dotted lines in the above figures 1-4, so as to form a palm model together with the main block; in the extending direction of the main shaft direction of the main block, whether an independent small block (a contact area formed by fingers) exists or not is searched, and the independent small block and the main block form a complete first contact module (a hand model).
2) For type2
In the extension direction of the main shaft direction of the main block, searching the contact surface of a little finger (or other fingers in some cases) to jointly form a palm side model; it should be noted that, due to the physiological characteristics of human hands, the angle formed by the major axis direction of the finger point block and the major axis direction of the palm main block is limited. Finger points outside the constraint threshold are determined not to be part of the palm-formed model, and as shown in type2, if there is a contact point on its right side, i.e., on the back of the hand, it is not part of the palm-formed model.
3) For type3
the main block included in type3 is more specific, and the area of the main block itself is greatly different from the area of the rectangle surrounding the main block, and if it is further determined whether the main block is a block of the type3, it is also possible to consider calculating the concave-convex feature of the main block. After the type3 is determined, contact surfaces formed by finger points are searched on a vertical extension line of a main shaft of the hand model (namely the direction opposite to the concave surface), and the contact surfaces jointly form the hand model.
After the model is built, which contact points are generated by normal operation and which contact points are mistakenly touched can be judged according to the model. For example, after the palm model is created, the palm contact area and the fingertip contact points are covered by the palm, and even if the palm is not completely contacted with the touch screen, the contact surface generated between the fingertip contact points in the palm contact area is marked as the mistaken touch because the contact surface is generated by the mistaken touch rather than the normal operation contact point. And small-area contact points outside the palm contact area and the fingertip contact area can be regarded as normal contact points.
In the embodiment of the invention, when the palm area connected with the thumb is determined, the sensing areas of the fingers can be matched, so that the sensing area corresponding to the palm area is determined; for example, when the difference between the areas of the 4 sensing regions is within a predetermined range and the distance between two adjacent sensing regions in the 4 sensing regions is within a predetermined threshold range, in other words, the areas of the 4 sensing regions are almost equal or the distances between the adjacent sensing regions are almost equal, as shown in fig. 1-4, the areas of the sensing regions 42 to 45 are all 4, that is, the areas of the sensing regions 42 to 45 are almost equal and the distances between the 4 sensing regions are almost equal, it can be determined that the sensing regions 42 to 45 are 4 fingers, then it can be determined that the sensing region 46 corresponds to a thumb, and it can be determined that the sensing region 41 and the sensing region 47 correspond to a palm, so as to establish the first touch model.
In the embodiment of the present invention, the raw data at least includes a value and a position of each sensing node on the touch detection unit; correspondingly, in step 402, the processing raw data of the touch event to obtain a sensing area includes: step 4020, performing connected domain scanning on the original data of the touch event according to the type of the value of the sensing node to obtain the sensing area.
Here, the above-mentioned step 4020 corresponds to the step 202 in the second embodiment, and therefore, those skilled in the art can understand the above-mentioned step 4020 by referring to the second embodiment, and for brevity, will not be described again here.
In this embodiment of the present invention, step 405, the determining the validity of the sensing area according to the first touch model includes:
step 4051, determining whether the area of the sensing region in the first touch model meets a preset condition, and obtaining a first determination result;
step 4052, determining the validity of the sensing region according to the first determination result.
Here, the steps 4051 to 4052 correspond to the steps 304 to 305 in the third embodiment, respectively, so that those skilled in the art can refer to the third embodiment to understand the steps 4051 to 4052, and the description is omitted here for brevity.

Fig. 5-1 is a schematic flow chart of an implementation of a five-information processing method according to an embodiment of the present invention, and as shown in fig. 5-1, the information processing method includes:
here, the steps 501 to 504 correspond to the steps 101 to 104 in the first embodiment, respectively, and therefore, a person skilled in the art can understand the steps 501 to 504 with reference to the first embodiment, and details are not repeated herein for brevity.
here, the second condition refers to the condition related to the first time interval, and the second condition may be a time threshold or a time range.
Here, step 507, based on the second determination result, determines an input object, including: when the second judgment result shows that the first time interval meets a preset second condition, inputting an input object corresponding to a next touch event as an effective input object, and judging a previous touch event as invalid; and when the second judgment result shows that the first time interval does not meet a preset second condition, judging that the two adjacent touch events are invalid.
The technical scheme provided by the embodiment of the invention can be used in the following scenes, when a user uses the virtual keyboard, the user wants to obtain the same effect as the mechanical keyboard, and actually the user taps the virtual keyboard according to the habit of using the mechanical keyboard, specifically, the user generally puts hands on the keyboard between the taps of the keyboard, as shown in fig. 5-2, at this time, the user does not really want to tap a character, but habitually puts the hands on the keyboard, and prepares for the next tapping; for example, a user intended to tap a string of characters "dasr", the input process for the user would typically be such that:
when the user starts to tap, the user puts the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters a, s, d and f respectively, then the user lifts the left hand and falls the middle finger to input the character d, then lifts the left hand and falls the little finger to input the character a, then the user lifts the left hand and falls the ring finger to input the character s, then the user lifts the left hand and falls the index finger to input the character r, and therefore the input of the string of characters "dasr" is completed.
In the process of inputting, when the user starts to tap, the user puts the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters 'a, s, d and f' respectively, and the user does not really want to tap the characters 'a, s, d and f' but is a habit based on a mechanical keyboard; then in the related art, such a habit based on a mechanical keyboard (placing the little finger, ring finger, middle finger and index finger of the left hand on the characters "a, s, d and f", respectively) causes the electronic device to recognize the characters "a, s, d and f", thereby inputting the characters "a, s, d and f", in other words, the user does not want to input the characters "a, s, d and f", i.e., the input of the characters "a, s, d and f" is a wrong operation. By adopting the technical scheme provided by the embodiment of the invention, the situation can be well avoided, because when a user puts the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters a, s, d and f respectively, the characters are not considered as a touch event, when the user lifts the hand to input the character d, the electronic equipment obtains a time interval (a first time interval), then judges whether the first time interval meets a preset second condition or not, and when the second condition is met, the touch event (when the user lifts the hand to input the character d) is taken as an effective touch event, so that the character d is input.

Fig. 6 is a schematic flow chart of an implementation of a sixth information processing method according to an embodiment of the present invention, and as shown in fig. 6, the information processing method includes:
601, acquiring original data of a touch event, wherein the touch event is a touch operation of an operating body on a touch detection unit;
here, the steps 601 to 604 correspond to the steps 101 to 104 in the first embodiment, respectively, and therefore, a person skilled in the art can understand the steps 601 to 604 with reference to the first embodiment, and details are not described herein for brevity.
here, the third condition refers to a condition regarding duration, and the third condition may be a time threshold or a time range.
Here, step 607, based on the third determination result, of determining an input object, includes: when the third judgment result shows that the duration time meets a preset third condition, inputting an input object corresponding to the touch event as an effective input object; and when the third judgment result shows that the duration time does not meet the preset third condition, inputting the input object corresponding to the touch event as an invalid input object.
The technical scheme provided by the embodiment of the invention can be used in the following scenes, when a user uses the virtual keyboard, the user wants to obtain the same effect as the mechanical keyboard, and actually the user taps the virtual keyboard according to the habit of using the mechanical keyboard, specifically, the user generally puts hands on the keyboard between the taps of the keyboard, as shown in fig. 5-2, at this time, the user does not really want to tap a character, but habitually puts the hands on the keyboard, and prepares for the next tapping; for example, a user intended to tap a string of characters "dasr", the input process for the user would typically be such that:
when the user starts to tap, the user puts the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters a, s, d and f respectively, then the user lifts the left hand and falls the middle finger to input the character d, then lifts the left hand and falls the little finger to input the character a, then the user lifts the left hand and falls the ring finger to input the character s, then the user lifts the left hand and falls the index finger to input the character r, and therefore the input of the string of characters "dasr" is completed.
In the process of inputting, when the user starts to tap, the user puts the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters 'a, s, d and f' respectively, and the user does not really want to tap the characters 'a, s, d and f' but is a habit based on a mechanical keyboard; then in the related art, such a habit based on a mechanical keyboard (placing the little finger, ring finger, middle finger and index finger of the left hand on the characters "a, s, d and f", respectively) causes the electronic device to recognize the characters "a, s, d and f", thereby inputting the characters "a, s, d and f", in other words, the user does not want to input the characters "a, s, d and f", i.e., the input of the characters "a, s, d and f" is a wrong operation. By adopting the technical scheme provided by the embodiment of the invention, the situation can be well avoided because when the user places the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters a, s, d and f respectively, the user does not consider the touch events to be an effective touch event, the electronic equipment needs to judge the duration of the touch event, because the user places the fingers on the characters, the duration of the placement is far longer than the duration of the touch events corresponding to the user when the user normally taps the characters (d, a, s and r), therefore, as long as the third condition is set reasonably, the user places the little finger, the ring finger, the middle finger and the index finger of the left hand on the characters a, s, d and f respectively to judge the touch events to be ineffective, and the following operations, such as the user lifts the left hand and drops the lower middle finger to input the character d, a valid touch event is determined. Therefore, by adopting the technical scheme provided by the embodiment of the invention, the misoperation of the user can be well avoided.
