[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0056] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".
[0057] In recent years, the functions of terminal devices have become more and more abundant, and the performance of various functions has gradually improved. For example, the touch accuracy of the touch display screen of the terminal device is getting higher and higher. Users can not only input click operations, sliding operations, drag operations, etc. through touching the touch display screen, but also complete writing operations by touching the touch display screen, that is, writing text or drawing, etc., especially with accessories such as stylus pens. Complete writing operations. However, in the related art, the user's touch operation on the touch display screen is often highly random, and the response effect of the touch display screen to the touch operation needs to be improved. For example, when a user writes on the touch display screen, the writing effect displayed on the touch display screen may be quite different from the actual effect, such as poor pen tracking; when a user clicks on the touch display screen, the touch display screen recognizes it as writing, sliding, and other operations, thereby reducing the success rate of the click.
[0058] Based on this, in the first aspect, at least one embodiment of the present disclosure provides a touch control method, please refer to the attached Figure 1 , which shows the process of the method, including steps S101 to S103.
[0059] Among them, the method can be applied to a terminal device with a touch screen, which can be used for both display and touch, that is, the user can input instructions by performing touch operations on the touch screen, such as writing, clicking, etc. on the touch screen. The method aims to accurately respond to the user's touch operation, that is, when the user performs a touch operation on the touch screen, the writing effect is displayed on the touch screen, and when the user performs a click operation on the touch screen, the response interface of the click operation is displayed on the touch screen, for example, after the user clicks the icon of an APP, the touch screen displays the homepage of the APP.
[0060] In step S101, touch information collected by a touch display screen is acquired, wherein the touch information includes a touch position of a stylus on the touch display screen.
[0061] The touch screen is provided with a touch circuit, which includes pixel subcircuits distributed at different positions of the screen, and each pixel subcircuit is used to collect touch operations on the corresponding pixel of the screen, that is, the pixel subcircuit can distinguish whether the corresponding pixel is touched. For example, a capacitor is provided in the pixel subcircuit, and the capacitance of the capacitor in the pixel subcircuit is different when the corresponding pixel is touched and when it is not touched, so the pixel subcircuit can determine whether the corresponding pixel is touched by the capacitance of the capacitor.
[0062] The position determined by the touch display screen according to the capacitance value of the capacitor in each pixel sub-circuit in the touch circuit is the original reporting point position collected by the touch display screen. After one or more pixel sub-circuits of the touch display screen collect the touch operation on the corresponding pixel, the touch display screen will determine the pixel corresponding to the one or more pixel sub-circuits on the display screen as the original reporting point position, that is, the touched pixel identified by the pixel sub-circuit is used as the original reporting point position.
[0063] The stylus pen may be an active pen or a passive pen. The tip of the stylus pen is thin and delicate, and has a small deformation. Therefore, when the stylus pen touches the touch display screen, it is easy to cause the problem of not being able to distinguish between writing and clicking.
[0064] Exemplarily, this step can use the original reporting point position collected by the touch display screen as the touch information. Optionally, this step is performed by the upper layer of software (the upper layer of software can be an application layer), that is, the touch display screen reports the input event carrying the original reporting point position to the upper layer of software, and the upper layer of software can use the original reporting point position in the input event as the touch information.
[0065] Exemplarily, this step can process the original reporting point position collected by the touch display screen using the first processing parameter to obtain the touch information, wherein the first processing parameter can be a processing parameter in a writing scene, a processing parameter in a non-writing scene, or other processing parameters. Optionally, this step is performed by the upper layer of software, that is, the touch display screen can process the original reporting point position using the first processing parameter, and report the input event carrying the processing result (that is, the touch position obtained after processing) to the upper layer of software, and the upper layer of software can use the processing result in the input event as touch information.
[0066] In step S102, the touch information is displayed on the touch display screen according to processing parameters in a touch scene to which the display interface on the touch display screen belongs.
[0067] Among them, the touch scene includes a writing scene and a non-writing scene. The writing scene refers to a scene in which a user writes, draws, etc. on a touch display screen with a stylus, and the non-writing scene refers to a scene in which a user inputs clicks and other operations on the touch display screen with a stylus. Exemplarily, before executing this step, the method can also determine the touch scene to which the display interface on the touch display screen belongs in the following manner: in response to the application to which the display interface belongs being a writing application, and / or the display interface containing a handwriting input hot zone of an input method, determining that the touch scene to which the display interface belongs is a writing scene; in response to the application to which the display interface belongs being a non-writing application, and the display interface not containing a handwriting input hot zone of an input method, determining that the touch scene to which the display interface belongs is a non-writing scene.
[0068] For example, the processor of the terminal device can control the display interface on the touch screen, so the processor is aware of the content of the display interface of the touch screen, that is, it can determine the application to which the display interface belongs, and whether the display interface contains the handwriting input hotspot of the input method. For example, the terminal device is pre-configured with an application whitelist, and the applications in the whitelist are writing applications. Therefore, after determining the application to which the display interface belongs, it can be further determined whether the application to which the display interface belongs is in the above whitelist. If so, it is determined that the application to which the display interface belongs is a writing application, and if not, it is determined that the application to which the display interface belongs is a non-writing application.
[0069] The processing parameters are used to make the display effect of the touch information meet the requirements of the touch scene, and the processing parameters include anti-shake parameters (such as jitter) and / or filtering parameters. It can be understood that the smaller the anti-shake parameters and filtering parameters are, the better the pen-following performance of the display effect is, and the larger the anti-shake parameters and filtering parameters are, the worse the pen-following performance of the display effect is, but the click success rate is higher.
[0070] The anti-shake parameter may also be referred to as a point stability parameter, which is used to characterize the minimum touch distance for updating the display position in the display effect, and the touch distance includes the distance between adjacent touch positions; in other words, the display position in the display effect is updated only when the distance between the first touch point and the second touch point on the touch display screen is greater than the anti-shake parameter, and the display position in the display effect is not updated if the distance between the first touch point and the second touch point is less than or equal to the anti-shake parameter, that is, after determining the first display position according to the first touch point, if the distance between the adjacent second touch point and the first touch point is less than or equal to the anti-shake parameter, the display position continues to be determined as the first display position, thereby reducing the jitter of the display position, and if the distance between the adjacent second touch point and the first touch point is greater than the anti-shake parameter, the display position is re-determined.
[0071] The filtering parameter is used to characterize the distance between the display position and the touch position in the display effect. The filtering parameter may be an alpha filtering parameter, a Kalman filtering parameter, etc. Taking the alpha filtering parameter as an example, the filtering process is shown in the following formula:
[0072] alpha=abs(current_x-last_x) / const_alpha
[0073] Where alpha is the distance between the current frame position before filtering and the previous frame position after filtering, current_x is the current frame position before filtering, last_x is the current frame position after filtering, and const_alpha is the filtering parameter.
[0074] It can be seen from the above formula that the larger the filtering parameter, the larger the distance between the positions before and after filtering, the worse the chirality, but the trajectory will be smoother due to filtering.
[0075] In a possible embodiment, when the touch information is the original reporting point position collected by the touch display screen, this step can display the touch information on the touch display screen in a writing scenario according to the processing parameters in the writing scenario, for example, the touch information is processed using the processing parameters in the writing scenario and then displayed on the touch display screen; in a non-writing scenario, the touch information is displayed on the touch display screen according to the processing parameters in the non-writing scenario, for example, the touch information is processed using the processing parameters in the non-writing scenario and then displayed on the touch display screen.
[0076] In this embodiment, corresponding processing parameters are used to process touch information in writing scenarios and non-writing scenarios respectively, so that the display effect of touch information can meet the requirements of the scenarios in both scenarios. For example, if the writing scenario requires the display effect to have strong pen-following performance, then this method can improve the pen-following performance of the display effect in the writing scenario. For another example, if the non-writing scenario requires the display effect to have a high click success rate, then this method can improve the display effect to have a high click success rate in the non-writing scenario.
[0077] In some possible examples of this embodiment, the scene division accuracy may be low. For example, when the display interface is the interface of a writing application, the touch scene is a writing scene, and the interface has a writing hot zone (the writing hot zone is an area in the display interface belonging to the writing scene, which is used to collect writing operations) and a non-writing hot zone (the non-writing hot zone is an area in the display interface belonging to the writing scene that is not used for writing operations; generally, in a writing scene with a writing hot zone, the non-writing hot zone is an area in the display interface outside the writing hot zone). The user may perform writing operations in the writing hot zone or click operations in the non-writing hot zone. Therefore, if the writing scene is used in this scene, If the touch information is processed and displayed using the processing parameters under the writing scene, click operations in non-writing hot zones will be responded to as sliding operations, resulting in an inaccurate response effect. For another example, when the display interface includes a handwriting input hot zone of an input method, the touch scene is a writing scene, and the interface has a writing hot zone (that is, this example can be a handwriting input hot zone) and a non-writing hot zone. The user may perform writing operations in the writing hot zone or click operations in the non-writing hot zone. Therefore, if the touch information is processed and displayed using the processing parameters under the writing scene in this scene, click operations in non-writing hot zones will be responded to as sliding operations, resulting in an inaccurate response effect.
[0078] Exemplarily, based on the above-mentioned problem in this embodiment, this step can display the touch information in the writing scenario in the following manner: in the writing scenario, in response to the touch position being located in the writing hot zone of the display interface, the touch information is displayed on the touch display screen according to the processing parameters in the writing scenario, for example, the touch information is processed using the processing parameters in the writing scenario and then displayed on the touch display screen; in the writing scenario, in response to the touch position being located in the non-writing hot zone of the display interface, the touch information is displayed on the touch display screen according to the processing parameters in the non-writing scenario, for example, the touch information is processed using the processing parameters in the non-writing scenario and then displayed on the touch display screen.
[0079] It is understandable that in the above example, the writing application and the input method program can configure the position of the writing hot zone and the non-writing hot zone of each interface in the terminal device, so that the terminal device can determine whether the touch position is within the writing hot zone. In addition, the terminal device can also send the touch position to the writing application and the input method program, so that the writing application and the input method program determine whether the touch position is within the writing hot zone, and return the determination result to the terminal device.
[0080] In another possible embodiment, when the touch information is the result of processing the original reporting point position using a first processing parameter, and the first processing parameter is a processing parameter under a writing scene, this step can be in response to the touch scene to which the display interface belongs being a writing scene, and the touch information is displayed on the touch display screen; or, in response to the touch scene to which the display interface belongs being a non-writing scene, the touch information is processed using a second processing parameter and then displayed on the touch display screen, wherein the display effect of the touch information processed using the second processing parameter is the same as the display effect of the original reporting point position processed using the processing parameter under the non-writing scene.
[0081] The first processing parameter may include an anti-shake parameter and a filtering parameter; and the second processing parameter includes an anti-shake parameter.
[0082] Exemplarily, after the original reporting point positions are processed using the anti-shake parameters in the first processing parameters, 100 original reporting point positions can be made into 80 touch positions. This is because if the distance between adjacent original reporting point positions is within the anti-shake parameters (for example, 10bp), one touch position will be formed; after the touch positions in the touch information are processed using the anti-shake parameters in the second processing parameters, 80 touch positions can be made into 70 display positions. This is because if the distance between adjacent touch positions is within the anti-shake parameters (5bp), one display position will be formed.
[0083] In this embodiment, the touch display screen can pre-process the original reporting point position using the processing parameters under the writing scenario, and report the processing results as touch information to the upper layer of the software, so that the upper layer of the software can directly display the touch information in the writing scenario, and use the second processing parameters to process the touch information in the non-writing scenario before displaying it. This can reduce the workload of the upper layer of the software and improve the efficiency of the touch response.
[0084] In another possible embodiment, when the touch information is a result obtained by processing the original reporting point position using a first processing parameter, and the first processing parameter is a processing parameter in a writing scene or a non-writing scene, this step can correct the first processing parameter according to the processing parameter in the touch scene to which the display interface belongs, and display the touch information on the touch display screen.
[0085] The display of touch information mentioned in this embodiment refers to directly displaying the touch information on the touch display screen.
[0086] Exemplarily, the first processing parameter may be corrected in the following manner: the first processing parameter is corrected to the processing parameter under the touch scene to which the display interface belongs. That is, in response to the touch scene to which the display interface belongs being a writing scene, and the first processing parameter is the processing parameter under the writing scene, the first processing parameter is maintained as the processing parameter under the writing scene; in response to the touch scene to which the display interface belongs being a writing scene, and the first processing parameter is the processing parameter under the non-writing scene, the first processing parameter is updated to the processing parameter under the writing scene; in response to the touch scene to which the display interface belongs being a non-writing scene, and the first processing parameter is the processing parameter under the non-writing scene, the first processing parameter is maintained as the processing parameter under the non-writing scene; in response to the touch scene to which the display interface belongs being a non-writing scene, and the first processing parameter is the processing parameter under the writing scene, the first processing parameter is updated to the processing parameter under the non-writing scene.
[0087] In this embodiment, the touch display screen can pre-process the original reporting point position using the current first processing parameter, and report the processing result as touch information to the upper layer of the software, so that the upper layer of the software can directly display the touch information; in addition, the upper layer of the software can also verify whether the first processing parameter is consistent with the current touch scene, and correct it if it is inconsistent, so that the touch information of the next frame can be consistent with the touch scene. This is because the touch scenes of the display interface corresponding to multiple consecutive frames of touch information are often consistent. Therefore, the corrected first processing parameter can make the display effect of the touch information meet the requirements of the touch scene.
[0088] Based on the problem of low scene division accuracy described in the first embodiment above (the problem will not be repeated here), this embodiment can correct the first processing parameter in the writing scene in the following manner: in the writing scene, in response to the touch position being located in the writing hot zone of the display interface, the first processing parameter is corrected to the processing parameter in the writing scene; in the writing scene, in response to the touch position being located in the non-writing hot zone of the display interface, the first processing parameter is corrected to the processing parameter in the non-writing scene.
[0089] It is understandable that in the above example, the writing application and the input method program can configure the position of the writing hot zone and the non-writing hot zone of each interface in the terminal device, so that the terminal device can determine whether the touch position is within the writing hot zone. In addition, the terminal device can also send the touch position to the writing application and the input method program, so that the writing application and the input method program determine whether the touch position is within the writing hot zone, and return the determination result to the terminal device.
[0090] Please refer to the attached Figure 2, which shows a flow chart of a touch control method obtained by combining the above multiple embodiments, including the following steps:
[0091] Step S201: the touch screen collects the original reported point position of the touch pen on the screen.
[0092] Step S202: the touch screen uses jitter1 and filter parameter 1 (ie, the first processing parameter in this example: the processing parameter in the writing scene) to process the original reporting point position.
[0093] Step S203: reporting input event 1 to the upper software layer (in this example, the upper software layer may be an application layer), wherein input event 1 carries the touch information obtained by processing the original reported point position.
[0094] Step S204: the upper software layer determines the touch scene of input event 1.
[0095] Step S205: directly respond to input event 1, thereby improving the writing effect.
[0096] Step S206: The upper layer of the software performs secondary processing on input event 1 using jitter2 (ie, the second processing parameter in this example), thereby improving the click success rate.
[0097] In this embodiment, the handwriting input hot zone of the writing application and input method directly responds to the motion trajectory of the input event 1 with excellent pen tracking performance, with rich pen stroke details; and in some click and focus pen operation scenarios, the input events that have undergone secondary anti-shake processing can give users a better operating experience.
[0098] Please refer to the attached Figure 3 , which shows a flow chart of a touch control method obtained by combining the above multiple embodiments, including the following steps:
[0099] Step S301: the touch screen collects the original reported point position of the touch pen on the screen.
[0100] Step S302: the touch screen uses jitter1 and filter parameter 1 (ie, the first processing parameter in this example: the processing parameter in the writing scene or the non-writing scene) to process the original reporting point position.
[0101] Step S303: reporting input event 1 to the upper layer of the software, wherein input event 1 carries the touch position obtained by processing the original reported point position.
[0102] Step S304: the upper software layer determines the touch scene of input event 1.
[0103] Step S305: Determine whether the touch position is in the writing hot zone.
[0104] Step S306: directly respond to input event 1 and calibrate the first processing parameter to a processing parameter in a writing scene, so that the writing effect can be improved in the next frame of touch information.
