Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "first," "second," "third," and "fourth," etc. in the description and claims of the present application are used for distinguishing between different objects and not for describing a particular sequential order. The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a touch identification method and device, electronic equipment and a computer readable storage medium, which can improve the accuracy of the electronic equipment in identifying error touch operation, thereby reducing unnecessary touch response.
The technical scheme of the present application will be described in detail with reference to specific embodiments.
The touch recognition method disclosed by the embodiment of the application is introduced more clearly. Touch recognition logic in the related art will be described first.
Taking touch logic of a capacitive touch screen in the related art as an example, the capacitive touch screen technology works by using current induction of a human body. When a finger touches the capacitive touch screen, due to the existence of a human body electric field, a coupling capacitor is formed between the human body and the surface of the capacitive touch screen, and the finger draws a small current from a contact point, so that a capacitance signal is generated, and besides the finger, the capacitance signal is also generated when the parts such as cheeks and ears touch the capacitive touch screen, so that the capacitance value of a capacitive sensor in a touch area is changed. That is, under the condition that the user performs the touch operation, the capacitance value of the capacitive sensor of the touch area will change, and the capacitive touch screen can determine that the touch operation of the user is monitored under the condition that the touch area with the capacitance value different from other areas is monitored in the full screen.
In practice, it is found that when a user holds the electronic device, the finger can not be mistakenly touched to the touch screen, and in addition, when the user receives a phone call, the cheek or the ear and other parts are easy to mistakenly touch to the touch screen, so that the electronic device performs unnecessary response, the use experience of the user is affected, and the power consumption of the electronic device is increased.
In this regard, the embodiment of the application discloses a touch recognition method to solve the above technical problems. Alternatively, the method may be applied to various electronic devices including capacitive touch screens, for example, portable electronic devices such as mobile phones and tablet computers, wearable devices such as smart watches and smart bracelets, and the like, which are not limited herein. Wherein: under the condition that the electronic equipment detects a first touch operation aiming at the capacitive touch screen, acquiring capacitance value information corresponding to the first touch operation; further, if the capacitance value information corresponding to the first touch operation is determined to be smaller than the target threshold value, the electronic device can determine that the first touch operation is a light touch operation, namely, an operation with smaller touch force, and the probability that the light touch operation is a false touch operation is larger; in addition, in the embodiment of the application, the electronic device can determine the touch force of the first touch operation by determining whether the capacitance value information corresponding to the first touch operation is smaller than the target threshold value, so that the technical problem that the related technology cannot identify the same position, and whether the touch operation at the same angle is a light touch or a heavy pressure is solved, and the probability that the electronic device identifies the error touch operation with the light force is improved.
Based on this, the touch recognition method and device, the electronic device and the computer readable storage medium disclosed in the embodiments of the present application are described below.
Referring to fig. 1, fig. 1 is a flow chart of a touch recognition method according to an embodiment of the disclosure. Alternatively, the method may be applied to the electronic device described above, or other execution subject, which is not limited herein. Optionally, the method may comprise the steps of:
102. under the condition that the first touch operation aiming at the capacitive touch screen is detected, acquiring capacitance value information corresponding to the first touch operation.
In an embodiment of the application, the electronic device may include a capacitive touch screen. Alternatively, the capacitive touch screen may be a straight panel screen, a curved panel screen, or the like, which is not limited herein. Wherein the curved screen is a screen in which the edges of the screen are curved.
As described above, the electronic device may determine whether the first touch operation for the capacitive touch screen exists by monitoring the change condition of the capacitance values corresponding to the capacitive sensors included in the capacitive touch screen. Optionally, the capacitance value information corresponding to the first touch operation may be a capacitance value corresponding to a first capacitive sensor included in the touch area, where the touch area is an action area of the first touch operation in the capacitive touch screen. Alternatively, the electronic device may collect a capacitance value corresponding to the first capacitive sensor in the touch area corresponding to the first touch operation when the first touch operation is detected, and determine the capacitance value information corresponding to the first touch operation according to the capacitance value corresponding to the first capacitive sensor in the touch area.
Alternatively, the capacitance information may include one or more of a capacitance peak value, a capacitance valley value, and a capacitance average value, which are not limited herein. The capacitance peak value is the largest capacitance value in the capacitance values corresponding to the first capacitance sensors included in the touch area; the capacitance valley value is the minimum capacitance value in the capacitance values corresponding to the first capacitance sensors included in the touch area; the capacitance average value is an average value of capacitance values corresponding to the first capacitance sensors included in the touch area.
Referring to fig. 2, fig. 2 is a schematic diagram of capacitance values of a capacitive touch screen according to an embodiment of the disclosure. Alternatively, the capacitive touch screen may include a transmit channel and a receive channel. Wherein, the capacitance value of the transmitting channel and the receiving channel to the ground is self-capacitance data value 100, and the data value corresponding to the transmitting channel and the receiving channel is mutual capacitance data value 110. Alternatively, self-contained data values 100 may include a Transmit (TX) self-contained data value 1001 and a Receive (RX) self-contained data value 1002, without limitation.
Optionally, the capacitance values collected by the capacitive touch screen may include a mutual capacitance data value 110, a Transmission (TX) self-capacitance data value 1001, a Reception (RX) self-capacitance data value 1002, and the like, which are not limited herein. The mutual capacitance data value 110 is generally used to determine whether a touch operation (e.g., a pressing operation or a lifting operation) is performed on the capacitive touch screen, and the self-capacitance data value 100 is generally used to perform other auxiliary function determination, such as proximity sensing function determination, etc., which is not limited herein.
As an optional embodiment, the electronic device may obtain a capacitance value currently corresponding to each capacitive sensor included in the capacitive touch screen; the electronic device may search the touch area in the capacitive touch screen according to the capacitance value corresponding to each capacitive sensor, where the touch area may be an area where the capacitance value corresponding to the first capacitive sensor is greater than the capacitance value threshold, and is not limited herein. The capacitance value threshold may be set by a developer based on a number of development experiences, and typical values may include 100, 150, or 200, etc., without limitation. Further, if the touch area is searched, the electronic device may determine that the first touch operation for the capacitive touch screen is detected.
For example, in connection with fig. 2, assume that the capacitance threshold is 100. As described above, the mutual capacitance data value 110 is generally used to determine whether there is a touch operation for the capacitive touch screen, and for this electronic device, the capacitive sensor with the mutual capacitance data value 110 greater than 100 can be searched for in the mutual capacitance data value 110 corresponding to the capacitive touch screen, and the area where the capacitive sensor with the mutual capacitance data value 110 greater than 100 is located is determined as the touch area 120. Since the embodiments of the present application discuss the case of a touch capacitive touch screen, the capacitance value corresponding to the capacitive sensor mentioned in the embodiments of the present application generally refers to the mutual capacitance data value 110; of course, in other possible explanations, the capacitance value of the capacitive sensor may also include the self-contained data value 100, which is not limited herein.
By implementing the method, the electronic equipment can quickly determine the touch area in the capacitive touch screen in a threshold screening mode, the implementation is simple and quick, and the implementation efficiency is improved.
104. If the capacitance value information is smaller than the target threshold value, determining that the first touch operation is the error touch operation, and not responding to the first touch operation.
Because the amounts of current respectively taken away by the finger pressing the capacitive touch screen heavily and the finger touching the capacitive touch screen lightly are different, the sizes of the generated capacitance signals are different, and finally the capacitance values after the change of the capacitance sensors are also different. In general, the capacitance value after the change of the capacitance sensor in the light touch is smaller than the capacitance value after the change of the capacitance sensor in the heavy pressure.
Fig. 3 is a schematic diagram of capacitance values of another capacitive touch screen according to an embodiment of the present application, for example, with reference to fig. 2 and 3. Wherein fig. 2 is a schematic diagram of capacitance values in the case of a touch, it can be seen that in the case of a touch: the peak value of mutual capacitance data value 110 is "358", the peak value of Reception (RX) self-capacitance data value 1002 is "605", and the peak value of Transmission (TX) self-capacitance data value 1001 is "662". Fig. 3 is a schematic diagram of capacitance values in the case of a heavy voltage, in which: the peak value of mutual capacitance data value 110 is "869", the peak value of Receive (RX) self-capacitance data value 1002 is "1142", and the peak value of Transmit (TX) self-capacitance data value 1001 is "1166". The capacitance value of the changed capacitive sensor is smaller than that of the changed capacitive sensor when the capacitive sensor is pressed heavily.
As described above, since the capacitance values corresponding to the capacitive sensors are different in the touch operation and the heavy-pressure operation, in this embodiment of the present application, a target threshold may be set for determining whether the first touch operation for the capacitive touch screen is the touch operation or the heavy-pressure operation.
Alternatively, the target threshold may be a capacitance value according to a change of the capacitance sensor when the touch is tapped, and a capacitance value according to a change of the capacitance sensor when the touch is pressed. Alternatively, the target threshold may be greater than the capacitance value of the capacitive sensor after a touch, and/or less than the capacitance value of the capacitive sensor after a heavy pressure, which is not limited herein. For example, in fig. 2 and 3, the target threshold may be greater than the peak "358" of the mutual capacitance data value 110 in the case of a light touch, and less than the peak "869" of the mutual capacitance data value 110 in the case of a heavy pressure, such as "350", "400", or "500", etc., without limitation.
In other alternative embodiments, the target threshold may be greater than the capacitance value of the capacitive sensor after a tap, less than the capacitance value of the capacitive sensor after a tap, and more closely approach the capacitance value of the capacitive sensor after a tap, so that the tap operation may be more accurately identified.
In yet other alternative embodiments, the target threshold may also be set by a developer based on a number of development experiences, not limited herein.
Based on the above, the electronic device may determine that the first touch operation is a light touch operation, that is, an operation with smaller touch force, when it is determined that the capacitance value information corresponding to the first touch operation is smaller than the target threshold. It can be understood that the normal touch operation of the user is the heavy pressure operation, and the high probability of the light touch operation is the unintentional error touch operation, so that the electronic device can determine that the first touch operation is the error touch operation and does not respond to the first touch operation, thereby reducing unnecessary touch response and reducing the power consumption of the electronic device.
By implementing the method disclosed in each embodiment, the electronic device may acquire the capacitance value information corresponding to the first touch operation when detecting the first touch operation for the capacitive touch screen; further, if the capacitance value information corresponding to the first touch operation is determined to be smaller than the target threshold value, the electronic device can determine that the first touch operation is a light touch operation, namely, an operation with smaller touch force, and the probability that the light touch operation is a false touch operation is larger; in addition, in the embodiment of the application, the electronic device can determine the touch force of the first touch operation by determining whether the capacitance value information corresponding to the first touch operation is smaller than the target threshold value, so that the technical problem that the related technology cannot identify the same position, and whether the touch operation at the same angle is a light touch or a heavy pressure is solved, and the probability that the electronic device identifies the error touch operation with the light force is improved.
Referring to fig. 4, fig. 4 is a flow chart of another touch recognition method according to an embodiment of the disclosure. Alternatively, the method may be applied to the electronic device described above, or other execution subject, which is not limited herein. Optionally, the method may comprise the steps of:
402. under the condition that the first touch operation aiming at the capacitive touch screen is detected, acquiring capacitance value information corresponding to the first touch operation.
404. And determining a target area corresponding to the first touch operation in the capacitive touch screen, and configuring a target threshold according to the target area.
Alternatively, the capacitive touch screen may be divided into a plurality of areas, and the dividing method may be determined by a developer or a user, which is not limited herein. Referring to fig. 5, fig. 5 is a schematic view illustrating area division of a capacitive touch screen according to an embodiment of the disclosure. In an alternative embodiment, the capacitive touch screen 500 may be divided into an edge region 510 and a non-edge region 520, wherein the edge region 510 may be a region near an edge of the capacitive touch screen, and the non-edge region 520 may be a region other than the edge region 510, which is not limited herein. Alternatively, the area of the edge region 510 and the non-edge region 520 may be larger than determined by a developer or a user, and is not limited herein.
Alternatively, in the case where the capacitive touch screen 500 is a curved screen, the edge region 510 may include a curved region of the curved screen, and/or an edge region of a straight plate portion of the curved screen, which is not limited herein. It should be noted that fig. 5 is only an alternative division manner, and should not be limited to the embodiment of the present application.
Alternatively, the electronic device may obtain a first coordinate corresponding to the touch area of the first touch operation in the capacitive touch screen, and determine, according to the first coordinate, a target area on which the first touch operation acts in the capacitive touch screen. Optionally, if the first coordinate falls within a first coordinate range corresponding to the edge region, the target region may be determined to be the edge region; if the first coordinate falls within a second coordinate range corresponding to the non-edge region, the target region can be determined to be the non-edge region.
The first coordinate range corresponding to the edge area and the second coordinate range corresponding to the non-edge area may be determined by a developer or a user, which is not limited herein.
Under the condition that the user normally uses the electronic equipment, different parts are adopted to touch different areas of the capacitive touch screen. For example, a finger tip is typically used to touch a non-edge area, which may be touched by the abdomen of the finger while holding the electronic device. The touch force of the fingertip is generally larger than that of the finger belly, and if the same target threshold is adopted for different areas, misjudgment is easy to occur. For example, since the touch force of the finger belly is small, the correspondingly set target threshold is small, and the small target threshold is suitable for the false touch operation of the screening edge area, but the fingertip touch for the non-edge area may be too small due to the small target threshold, so that the false touch operation of the fingertip with small partial force cannot be identified as the false touch operation, namely the false judgment occurs.
Optionally, the electronic device may configure a corresponding value for the target threshold according to the target area corresponding to the first touch operation in the capacitive touch screen, so as to improve accuracy of the electronic device in identifying the error touch operation, thereby reducing unnecessary touch response.
As an optional implementation manner, the electronic device may configure the target threshold to be a first value in a case where the target area is determined to be an edge area; optionally, the electronic device may configure the target threshold to be a second value when determining that the target area is a non-edge area, where the second value may be greater than the first value.
As described above, the touch force for the non-edge area is generally larger, so that the force for the false touch operation for the non-edge area is also larger, so that by implementing the method, the electronic device can set the value of the target threshold higher under the condition that the first touch operation is determined to act on the non-edge area, so that some false touch operations for the non-edge area cannot be identified, thereby improving the accuracy of the electronic device in identifying the false touch operation and reducing unnecessary touch response.
When a user actually touches a capacitive touch screen, in some usage scenarios, a situation that multiple touch operations are detected simultaneously may occur. The electronic equipment can determine the current use scene according to the detected one or more touch operations, and further configure a target threshold matched with the use scene.
Optionally, in the case that the first touch operation acts on the edge area of the capacitive touch screen, if the second touch operation is detected in the non-edge area of the capacitive touch screen, the electronic device may determine that the user is currently using the fingertip normally in the case of touching the capacitive touch screen.
It can be understood that, under the condition that the user normally uses the fingertip to touch the capacitive touch screen, the touch operation force of the fingertip on the edge area is also larger, so that the target threshold value can be increased for the electronic device, and the first touch operation with larger touch force than usual is also determined as the error touch operation, so that the accuracy of the electronic device for identifying the error touch operation can be improved. The increased target threshold value may be smaller than a capacitance value corresponding to normal fingertip touch, so as to avoid determining the normal fingertip touch as a false touch operation.
Further, the electronic device may determine whether the capacitance value information corresponding to the first touch operation is smaller than the increased target threshold; optionally, if the capacitance value information corresponding to the first touch operation is smaller than the increased target threshold, the electronic device may determine the first touch operation as a false touch operation.
By implementing the method, under the condition that the touch operation is detected by the electronic equipment in the edge area and the non-edge area at the same time, the situation that the user normally uses the fingertip to touch the capacitive touch screen is determined, and then the target threshold value can be increased by the electronic equipment, so that the first touch operation with larger touch force than usual is also determined to be the error touch operation, and the accuracy of the electronic equipment for identifying the error touch operation can be improved.
As an optional implementation manner, in the case that the first touch operation is determined to be a false touch operation, the electronic device may restore the target threshold value after the increase to the value before the increase after waiting for the first time period. In another optional embodiment, in the case that the electronic device determines that the first touch operation is a false touch operation, if the second touch operation is not detected within the second period of time, the target threshold after the increase may be restored to the value before the increase.
After waiting for the first time period or when the second touch operation is not detected in the non-edge area of the capacitive touch screen within the second time period, the high probability can determine that the user is not using the fingertip touch capacitive touch screen normally at the moment, and the electronic device can restore the increased target threshold value to the value before the increase, so that the electronic device is prevented from determining the normal touch operation with smaller individual force as the error touch operation, and the accuracy of the electronic device in identifying the error touch operation is improved.
406. If the capacitance value information is smaller than the target threshold value, determining that the first touch operation is the error touch operation, and not responding to the first touch operation.
In the practical application process, the first touch operation of which some capacitance value information is smaller than the target threshold value may be caused by short touch of clothes or a user, and the touch operation is not a complete touch operation, so that the short touch operation can be directly eliminated.
Alternatively, if it is determined that the capacitance value information corresponding to the first touch operation is smaller than the target threshold, the electronic device may further determine whether the target frame number of the capacitance value information which is detected to be smaller than the target threshold is greater than or equal to the frame number threshold; if so, determining the first touch operation as the error touch operation. The target frame number may represent a duration of the first touch operation, and the greater the target frame number, the longer the duration of the first touch operation, and vice versa, the shorter the target frame number.

Referring to fig. 6, fig. 6 is a flow chart of another touch recognition method according to an embodiment of the disclosure. Alternatively, the method may be applied to the electronic device described above, or other execution subject, which is not limited herein. Optionally, the method may comprise the steps of:
602. under the condition that the first touch operation aiming at the capacitive touch screen is detected, acquiring capacitance value information corresponding to the first touch operation.
604. And acquiring a current target display mode of the capacitive touch screen, and configuring a target threshold according to the target display mode.
In this embodiment of the present application, the current target display mode of the capacitive touch screen may include a vertical screen display mode or a horizontal screen display mode, which is not limited herein. Since the gesture of the user holding the electronic device and the usage scenario are different in different display modes, the magnitude of the force of the erroneous touch operation may also be different in different display modes.
Optionally, the electronic device may configure a corresponding target threshold according to the current target display mode of the capacitive touch screen, so as to improve accuracy of the electronic device in identifying the error touch operation, thereby reducing unnecessary touch response.
As an optional implementation manner, the electronic device may acquire current acceleration information of the electronic device; and the current target display mode of the capacitive touch screen can be determined according to the historical display mode corresponding to the capacitive touch screen at the last moment and the current acceleration information.
Referring to fig. 7, fig. 7 is a schematic diagram of an X-axis direction and a Y-axis direction of an electronic device according to an embodiment of the disclosure. Alternatively, the acceleration information may include at least an acceleration of the electronic device 700 in the X-axis direction, and/or an acceleration of the electronic device 700 in the Y-axis direction. As shown in fig. 7, the X-axis direction may be a horizontal direction of the electronic device, and the Y-axis direction may be a vertical direction of the electronic device, which is not limited herein.
In other alternative embodiments, the acceleration information may further include acceleration in a Z-axis direction, which may be a direction perpendicular to the capacitive touch screen, which is not limited herein.
Further optionally, the electronic device may determine, when a history display mode corresponding to the moment on the capacitive touch screen is the first display mode, whether an acceleration of the electronic device in the target axis direction included in the acceleration information is within an acceleration threshold interval; if yes, determining that the current target display mode of the capacitive touch screen is a second display mode; if not, determining the current target display mode of the capacitive touch screen as a first display mode.
Wherein, under the condition that the first display mode is a vertical screen display mode, the target axis is an X axis, and the second display mode is a horizontal screen display mode; and under the condition that the first display mode is a horizontal screen display mode, the target axis is a Z axis, and the second display mode is the vertical screen display mode. Alternatively, the acceleration threshold interval may be matched with the target axis, that is, different target axes correspond to different acceleration threshold intervals, and the specific value may be set by a developer according to a large amount of development experience, which is not limited herein. Alternatively, in the case where the first display mode is the portrait display mode, the target axis is the X axis, and in the case where the second display mode is the landscape display mode, the acceleration threshold interval may include-8 to-9.8, or 8 to 9.8, which is not limited herein.
In an optional embodiment, if it is determined that the acceleration of the electronic device in the target axis direction included in the acceleration information is within the acceleration threshold interval, the electronic device may further determine whether a target duration for which the acceleration of the electronic device in the target axis direction is within the acceleration threshold interval is greater than a duration threshold.
And if the acceleration of the electronic equipment in the target axis direction is in the continuous target duration in the acceleration threshold interval and is larger than the duration threshold, the display mode of the capacitive touch screen can be ensured to be indeed switched, and the current target display mode of the capacitive touch screen can be ensured to be the second display mode.
If the acceleration of the electronic device in the target axis direction is in the continuous target duration in the acceleration threshold interval and is smaller than or equal to the duration threshold, it can be determined that the display mode of the capacitive touch screen is not switched, and it can be determined that the current target display mode of the capacitive touch screen is still the first display mode.
For example, in the case that the history display mode corresponding to the previous moment on the capacitive touch screen is the vertical screen display mode, if the acceleration of the electronic device in the X-axis direction is within the acceleration threshold interval and the duration target time length is greater than the duration threshold, it may be determined that the current target display mode of the capacitive touch screen is the horizontal screen display mode; if the acceleration of the electronic equipment in the X-axis direction is in the acceleration threshold interval, but the continuous target duration is smaller than or equal to the duration threshold, the current display mode of the capacitive touch screen can be determined to be still a vertical screen display mode; in addition, if the acceleration of the electronic device in the X-axis direction is not within the acceleration threshold interval, it can be determined that the current display mode of the capacitive touch screen is still the vertical screen display mode.
In the case that the first display mode is a horizontal screen display mode, the target axis is a Z axis, and the second display mode is the vertical screen display mode, the judgment logic is similar to that described above, and will not be described here again.

For example, in the case of a capacitive touch screen in a horizontal screen display mode, generally, an electronic device is running an entertainment game function, in the process, the probability of a user making a touch operation is small, a smaller target threshold value can be adopted for the touch operation, and false touch operation is prevented from being frequently identified, so that touch sensitivity in the entertainment game process can be improved.
Further optionally, the electronic device may determine whether the electronic device is running an entertainment game function when determining that the target display mode is a landscape display mode, and if so, configure the target threshold to be a fourth value; if not, the target threshold is configured to be a third value.
