Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

The terminology used in the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in this specification and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in the present invention to describe various information, such information should not be limited by these terms. These terms are only used to distinguish the same type of information from each other. For example, 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, without departing from the scope of the present invention. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determining."

Smart terminals with touch function can be used in scenarios that require touch function, such as conferences, teaching, and outdoor live broadcasts. In order to meet the needs of the scene, the touch control system of the smart terminal can realize fine touch response. In some scenarios, each time the touch position changes by one pixel, the touch system needs to report touch data with touch position data at least once, where the touch position data represents the touch position, and the touch position may also be called the touch position in some scenarios. or writing position. The difference between the touch positions reported in two adjacent times may correspond to one pixel, that is, the change in the touch positions reported in two adjacent times is less than or equal to one pixel unit. This shows that a pixel unit includes at least one touch unit, which represents the smallest unit that the touch system can distinguish. The smaller the smallest unit that can be distinguished, the higher the touch precision of the touch system, and the touch precision here can also be Called touch accuracy or writing finesse.

The designers of the solution of the present invention have found through repeated research that when the touch system is a capacitive, resistive, pressure-sensitive and other type of touch control system, the phenomenon that the cursor frequently vibrates during the fine touch is less likely to occur. When the touch system is an electromagnetic touch system, if the electromagnetic pen touches the screen, that is, when the pen is in a writing state, a fine touch response can improve the writing precision.

If the electromagnetic pen does not touch the screen and is suspended in a space within a certain range from the screen (this situation is referred to as a suspended state in the present invention), the cursor frequently shakes frequently during the process of finely responding to the touch. The certain range mentioned here is determined by the effective range that the electromagnetic board can sense the electromagnetic signal.

The designer of the solution of the present invention further studied and analyzed this phenomenon and found that when the electromagnetic pen is suspended in a space within a certain range from the screen, the electromagnetic board in the touch system can also sense the electromagnetic signal emitted by the electromagnetic pen and the change of the magnetic flux. The frequency of the sensed electromagnetic signal is different from the frequency of the electromagnetic signal emitted when the electromagnetic pen is in the writing state. In response, the operating system controls the display screen to display the cursor.

Although the display screen shows the cursor, in order to ensure the fine control in the writing state, even in the non-writing state, a pixel unit includes at least one touch unit, and the touch system needs to report at least once every pixel that the touch position changes. Touch Data. Subsequently, the operating system connected by the touch control system controls the cursor position to change following the change of the touch position.

The designer of the solution of the present invention further found that under the condition that the touch control system finely responds to the change of the touch position, if the electromagnetic pen is suspended in a space within a certain range from the screen, the uncontrollable shaking of the user's arm and the unintentional movement of the body will all be affected. It will cause the change of the position of the electromagnetic pen and the change of the touch position. The change of the touch position is likely to cause the touch system to frequently report the changed touch position, which is prone to the phenomenon that the cursor frequently jitters, and the frequent jitter of the cursor may cause unnecessary resource consumption. In view of this, the designer of the present invention proposes a method for processing touch data.

In the touch data processing method, by judging the current state of the electromagnetic pen, when the electromagnetic pen is in the writing state, the touch data of the electromagnetic pen can be determined according to the first working mode; when the electromagnetic pen is in the floating state, the touch data of the electromagnetic pen can be determined according to the second working mode. The mode determines the touch data of the electromagnetic pen, and the touch accuracy corresponding to the determined touch position is lower than the touch accuracy in the first working mode in the writing state, so that the change frequency of the cursor position can be reduced, thereby reducing the cursor position as much as possible. frequent jitter to avoid unnecessary resource consumption.

The following describes a system for implementing touch data processing according to an embodiment of the present invention with reference to the accompanying drawings:

Please refer to FIG. 1A . FIG. 1A is an architectural diagram of a touch data processing system 100 according to an exemplary embodiment of the present invention. The processing system 100 may include a touch control system 120 . The touch system 120 is connected to the electromagnetic touch screen and the host device 140 , and may include an electromagnetic touch sensor (such as the electromagnetic board 121 in FIG. 1A ) and a touch processor 122 . The host device 140 is equipped with an operating system 141 .

In practical applications, the touch system 120 may be mounted on an electromagnetic touch screen, and the two may be referred to as touch devices. The host device 140 may refer to the host of a computer device or a part of the device used to implement touch response in the host. The electromagnetic touch screen may Refers to electromagnetic touch input devices independent of computer devices, and can also refer to electromagnetic touch input devices installed on various computer devices. The computer devices here can be laptop computers, smart phones, personal digital Assistants, media players, navigation devices, smart interactive tablets, e-mail devices, game consoles, tablet computers, smart locomotives, driverless cars, smart refrigerators, other smart home devices, or any combination of these devices combination.

The electromagnetic plate 121 included in the touch control system 120 is an electromagnetic touch sensor, and the sensed touch signal may include the change of the magnetic flux and the frequency of the electromagnetic signal. Among them, the transformation amount of the magnetic flux is related to the touch position, and the frequency of the electromagnetic signal can indicate whether the electromagnetic pen touches the screen, and the pressure exerted by the user on the electromagnetic pen.

When the user exerts different pressure on the electromagnetic pen (pen tip), the "pressure sensor" inside the electromagnetic pen feels different pressure, and the frequency of the electromagnetic signal sent out according to the sensed pressure is different. Correspondingly, the frequency of the electromagnetic signal sensed by the electromagnetic plate 121 will also be different.

The touch processor 122 is a touch processing chip of the touch system 120. The touch processing chip mentioned here may be a main control chip (also referred to as a main processing chip or a central processing unit) of the touch system 120, or a It may be an additional processing chip added to the touch control system 120, and the processing chip may be installed in the electromagnetic touch input device.

After receiving the touch signal sent by the electromagnetic board 121, the touch processor 122 may generate touch data corresponding to the touch signal, and the touch data may include touch position data corresponding to the magnetic flux change and pressure data corresponding to the frequency. The touch position data may include the X coordinate and the Y coordinate of the touch position; the pressure sensitivity data may include a pressure value, and the thickness of the line finally displayed on the screen will also be different depending on the pressure value.

In this embodiment of the present invention, in order to solve the problem of frequent cursor shaking, the touch processor 122 can preset different working modes corresponding to different states of the electromagnetic pen, wherein the writing state corresponds to the first working mode, and the floating state corresponds to the second working mode.

During the working process, the touch processor 122 can determine the current state of the electromagnetic pen. If it is in the writing state, the touch data of the electromagnetic pen is determined according to the first working mode; if it is in the floating state, it is determined according to the second working mode. touch data of the electromagnetic pen; the touch accuracy in the second working mode is lower than the touch accuracy in the first working mode. The first working mode and the second working mode mentioned here can be implemented in multiple ways, two of which are listed below:

In the first type, the first working mode corresponds to the first touch resolution, the second working mode corresponds to the second touch resolution, and the second touch resolution is lower than the first touch resolution. After receiving the tactile data, the touch processor 122 can determine the current state of the electromagnetic pen. If it is in the writing state, determine the touch position data of the electromagnetic pen according to the predetermined first touch resolution; if it is in the floating state, according to A second touch resolution lower than the first touch resolution determines touch position data of the electromagnetic pen.

After the touch position data is determined according to the corresponding working mode, the touch processor 122 generates touch data including the determined touch position data, and reports it to the operating system 141, which can be realized with high touch resolution when the electromagnetic pen is in the writing state. For fine writing, when the electromagnetic pen is in a predetermined floating state, the reported touch position change frequency is reduced with a low touch resolution, the change frequency of the cursor position is reduced, the frequent shaking of the cursor is minimized, and unnecessary resource consumption is avoided.

It should be noted that the first touch resolution and the second touch resolution are similar to the display resolution of the screen, and represent the number of touch units in the screen. The difference is: the value of the first touch resolution A value greater than the second touch resolution. In addition, the first touch resolution and second touch resolution mentioned here can be set according to the display resolution of the display screen (associated display screen) included in the screen, for example, the first touch resolution is higher than or equal to the associated display screen The resolution of the display screen of the second touch is lower than the resolution of the associated display screen.

Second, the touch resolutions corresponding to the first working mode and the second working mode are the same, and the touch position data can be generated according to the same predetermined touch resolution. However, after the touch position data is generated according to the predetermined touch resolution, in the first working mode, the generated touch position data is directly used as the current touch position data of the electromagnetic pen, and the touch data including the touch position data is determined as the touch position data of the electromagnetic pen. Touch Data.

In the second working mode, after the touch position data is generated, it is judged whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value; if it is greater, the generated touch position data is directly used as the current touch position data of the electromagnetic pen , determine that the touch data containing the touch position data is the touch data of the electromagnetic pen, if not greater than, discard the generated touch position data, determine that the touch data of the electromagnetic pen is empty, or determine that the touch data contains the previous touch The touch data of the position data is the touch data of the electromagnetic pen. Wherein, the predetermined distance value is greater than or equal to the distance value of adjacent touch units under the predetermined touch resolution.

Here, to determine whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value, the judgment can be made according to the currently generated touch position data and the previously generated touch position data, or according to the shooting time and the shooting time of the camera. The motion trajectory of the electromagnetic pen can be judged, and the judgment can also be made in other ways, which will not be repeated here.

The first working mode and the second working mode can be implemented in other ways in addition to the aforementioned two implementation modes, as long as the touch accuracy in the first working mode is higher than that in the second working mode, and the specific implementation mode will not be repeated here. .

Furthermore, in order to perform a touch response, after the touch data is generated by the touch processor 122, it can be directly sent to the operating system 141, which controls subsequent touch responses. In this way, through different working modes, it is possible to ensure fine writing in the writing state and at the same time reduce the frequency of changes of the cursor position in the floating state, thereby reducing the frequent shaking of the cursor as much as possible and avoiding unnecessary resource consumption

In addition, in order to further save resources or reduce cursor jitter, in each working mode, after the touch processor 122 generates touch data including the determined touch position data, it can determine the touch position data and pressure sensitivity generated twice adjacently. Whether the data are the same, if the two are the same, the reporting of the touch data can be abandoned this time, and if any one of the data is different, report to the operating system 141 again.

In some examples, the touch processor 122 is integrated on the touch motherboard of the touch system 120 , and when the touch data is manipulated to the operating system 141 , it can be transmitted through a data line between the touch motherboard and the host device 140 .

After the operating system 141 receives the touch data, it can send the received touch data to the touch driver contained therein, and the touch driver parses the touch data to trigger a response operation of the touch data.

In addition, in order to respond to the touch data, the touch driver may send the parsed touch data to the input subsystem (input_device) in the operating system 141 .

The input subsystem can be composed of a device driver layer, an input core layer and an event processing layer. The device driver layer can convert the underlying hardware input into a unified event form and report to the input core layer. The device registration and operation interface input by the driver layer notifies the event processing layer to process the event.

In some scenarios, while reducing the frequent shaking of the cursor as much as possible, the requirements for touch precision when writing with an electromagnetic pen are also very high. With the improvement of touch precision, the touch processor needs to process more and more signals. , the requirements for its signal processing capabilities are also getting higher and higher. In order to handle the signal processing capabilities of the touch processor, a high-performance processor needs to be used, and the high-performance processor is expensive and bulky, which will cause the cost of the touch device. increase and increase in size. In order to solve this problem at the same time, the designer of the present invention proposes another system that can realize the processing of touch data according to the embodiment of the present invention:

Please refer to FIG. 1B . FIG. 1B is an architectural diagram of a touch data processing system 200 according to another exemplary embodiment of the present invention. The processing system 200 may include a touch control system 220 . The touch system 220 is connected to the electromagnetic touch screen and the host device, and may include an electromagnetic touch sensor (such as the electromagnetic board 221 in FIG. 1B ), and the host device is equipped with an operating system 240 .

In practical applications, the touch system 220 can be mounted on an electromagnetic touch screen, and the two can be called touch devices. Electromagnetic touch input devices independent of computer equipment, and can also refer to electromagnetic touch input devices installed on various computer equipment, the computer equipment here can be laptop computers, smart phones, personal digital assistants , media players, navigation devices, smart interactive tablets, e-mail devices, game consoles, tablet computers, smart locomotives, driverless cars, smart refrigerators, other smart home devices, or a combination of any of these devices .

The technical content of this embodiment can refer to the embodiment involved in FIG. 1A , the difference is that after the electromagnetic plate 221 senses the touch signal, the touch system 220 does not need to convert the touch signal into a touch signal, but transmits the touch signal to the operating system 240 . tactile signal.

When the touch control system 220 transmits the tactile signal to the operating system 240, if the electromagnetic board 221 is a device with both control function and acquisition function, such as an electromagnetic touch sensor chip, the electromagnetic board 221 can directly transmit it to the operating system 240 through a predetermined interface. the tactile signal. The predetermined interface mentioned here can be a USB-bulk interface, an RS232 interface or a USB-hid interface (hid is the abbreviation of Human Interface Devices, that is, a human-machine interface device), etc. The USB-hid interface can be a general USB-hid interface , in addition, the predetermined interface may also be a signal transmission interface customized by the designer of the solution of the present invention or other equipment manufacturers.

In other examples, the touch system 220 may further include a touch processor 223. When the touch device 120 transmits a touch signal to the operating system, if the electromagnetic board 221 does not have a control function, the touch processor 223 can transmit the touch signal from the electromagnetic board 221 to the operating system. The tactile signal is read, and then the touch processing core 223 transmits the tactile signal to the transmission operating system 240 through the predetermined interface. The touch processing core 223 mentioned here may be the main control chip (also referred to as the main processing chip or the central processing unit) of the touch control system 220 , or may be an additional processing chip added to the touch control system 220 . It can be installed inside the touch device or outside the touch device.

After receiving the touch sensing signal, the operating system 240 may generate touch data corresponding to the touch sensing signal, wherein the touch data may include touch position data corresponding to the magnetic flux change amount and pressure sensing data corresponding to the frequency. The touch position data and the pressure-sensing data are as described above and will not be repeated here.

In this embodiment of the present invention, in order to solve the problem of frequent cursor shaking, the operating system 240 may preset different working modes corresponding to different states of the electromagnetic pen, wherein the writing state corresponds to the first working mode, and the floating state corresponds to the second working mode.

During the working process, the operating system 240 can determine the current state of the electromagnetic pen, and if it is in the writing state, determine the touch data of the electromagnetic pen according to the first working mode; if it is in the floating state, determine the state of the electromagnetic pen according to the second working mode. Touch data of the electromagnetic pen; the touch accuracy in the second working mode is lower than the touch accuracy in the first working mode. The first working mode and the second working mode mentioned here can be implemented in multiple ways, two of which are listed below:

In the first type, the first working mode corresponds to the first touch resolution, the second working mode corresponds to the second touch resolution, and the second touch resolution is lower than the first touch resolution. After the operating system 240 receives the touch data, it can determine the current state of the electromagnetic pen, and if it is in the writing state, determine the touch position data of the electromagnetic pen according to the predetermined first touch resolution; The second touch resolution of the first touch resolution determines touch position data of the electromagnetic pen. Wherein, the first touch resolution and the second touch resolution are the same as those in the foregoing embodiments, and details are not described herein again.

After determining the touch position data according to the corresponding working mode, the operating system 240 generates touch data including the touch position data.

In some scenarios, it is the signal processing code 241 that receives the tactile signal in the operating system 240, and the signal processing code 241 is a module in a logical sense, which is used to convert the received tactile signal into touch position data according to different working modes, and then Generate touch signals.

When converting tactile signals, the signal processing code 241, as a module in a logical sense, can be processed by the central processing unit (also called the main control chip or the main processing chip) of the host device where it is located, or by other processors other than the central processing unit. The processing chip is formed by reading corresponding computer program instructions in a readable medium such as a non-volatile memory into the memory to run. The processor of the host device or other processing chips other than the processor can read the program instructions stored in its memory, and in response, convert the touch signal into a touch signal.

After the touch signal is converted into a touch signal, in order to facilitate subsequent identification and response of the touch signal by the operating system, in an example, the signal processing code 241 may transmit the touch signal to the touch device. When transmitting the touch signal here, it can also be transmitted through the above-mentioned predetermined interface.

In order to realize the touch response, the touch system 220 carried on the touch device may include memory and non-volatile memory, and the memory may store a code for encoding a touch signal, and the code includes executable program instructions. After receiving the signal, the touch processor 223 can read executable program instructions from the non-volatile memory to the memory to run, forming a module in a logical sense, and the module can be referred to as a signal encoding code. In response, the signal encoding code The received touch signal may be encoded according to a standard data encoding specification and then transmitted to the operating system 240 . The encoded touch signal is parsed by the touch driver 245 of the operating system 240 . Furthermore, the parsed touch signal can be transmitted to the input subsystem 243, and the input subsystem 243 can directly recognize it and generate a corresponding touch event. For the input subsystem 243, reference may be made to the foregoing embodiments, and details are not described herein again.

In another example, after the operating system 240 generates the touch signal, the embodiment of the present invention may not return the touch signal to the touch device, but transmit the touch signal to the input subsystem (input_device) in other ways to respond, such as a signal The processing code 241 generates a touch signal, and sends the touch signal to the virtual touch device. The virtual touch device encodes the received touch signal according to the data encoding specification supported by the input subsystem 243, and sends it to the input subsystem 243, while the input subsystem 243 encodes the received touch signal. 243 generates a corresponding touch event in response to the touch signal encoded by the virtual touch device.

Among them, the virtual touch device is a virtual device with touch device function simulated by software and running in the operating system 240. After starting to run, the data encoding of the signal transmitted to the input subsystem 243 can be reserved to the input subsystem 243. The specification, that is, the data encoding specification supported by the input subsystem 243, the data encoding specification may be a valid data encoding specification extracted from a standard data encoding specification, or may be a predetermined data encoding specification.

Second, the touch resolutions corresponding to the first working mode and the second working mode are the same, and the touch signals can both be generated at the same predetermined touch resolution. However, after the touch position data is generated according to the predetermined touch resolution, in the first working mode, the operating system 240 directly regards the generated touch position data as the current touch position data of the electromagnetic pen, and determines that the touch data including the touch position data is all the touch position data. touch data of the electromagnetic pen.

In the second working mode, after the operating system 240 generates the touch position data, it determines whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value; touch position data, determine that the touch data containing the touch position data is the touch data of the electromagnetic pen, if not greater than, discard the generated touch position data, and determine that the touch data of the electromagnetic pen is empty, or determine that the touch data contains The touch data of the previous touch position data is the touch data of the electromagnetic pen. Wherein, the predetermined distance value is greater than or equal to the distance value of adjacent touch units under the predetermined touch resolution.

Here, to determine whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value, the judgment can be made according to the currently generated touch position data and the previously generated touch position data, or according to the shooting time and the shooting time of the camera. The motion trajectory of the electromagnetic pen can be judged, and the judgment can also be made in other ways, which will not be repeated here.

In some scenarios, the operations of the operating system 240 in the first working mode and the second working mode may be performed by the signal processing code 241 . For details, refer to the foregoing embodiments, which will not be repeated here.

After the touch signal is generated, the operating system 240 may send the touch signal to the touch device or the virtual touch device. For the detailed process, please refer to the content involved in the foregoing embodiments, which will not be repeated here.

In addition to the aforementioned two implementation manners, the embodiments of the present invention may also be implemented in other manners in addition to the first working mode and the second working mode, as long as the touch accuracy in the first working mode is higher than that in the second working mode. Repeat.

It can be seen from the above implementation that the operating system 240 can convert the touch signal into a touch signal according to different working modes, and transmit it back to the touch device or virtual touch device for subsequent touch response, while avoiding the cursor shaking as much as possible, without touching the device. Converting the touch signal to the touch signal can reduce the performance requirements of the control chip, and then a low-performance chip can be used as the control chip in the touch device, so the cost and volume of the touch device can be reduced.

The following describes the processing process of the touch data in detail in conjunction with the accompanying drawings:

Please refer to FIG. 2A, which is a flowchart of a method for processing touch data according to an exemplary embodiment of the present invention, including the following steps S201-S203:

Step S201, determining the current state of the electromagnetic pen.

Step S202 , if it is in the writing state, determine the touch data of the electromagnetic pen according to the first working mode.

Step S203: If it is in the floating state, determine the touch data of the electromagnetic pen according to the second working mode; the touch accuracy in the second working mode is lower than the touch accuracy in the first working mode.

Wherein, when determining the current state of the electromagnetic pen, it can be judged according to the electromagnetic touch sensor in the touch system, such as the frequency of the electromagnetic signal received by the electromagnetic board. In one example, the state of the electromagnetic pen can be determined by the following operations:

Determine the current state of the electromagnetic pen according to the frequency of the electromagnetic signal sensed by the electromagnetic board;

If the frequency of the electromagnetic signal is within a predetermined writing frequency range, it is determined that the electromagnetic pen is currently in a writing state.

In some scenarios, if the frequency is within a predetermined suspension frequency range, it can be determined that the electromagnetic pen is currently in a predetermined suspension state. The writing frequency range and the levitation frequency range mentioned here are determined by the internal configuration of the electromagnetic pen, which varies with the configuration of the electromagnetic pen, and can be any frequency value, which is not limited in this embodiment of the present invention.

In another scenario, considering that when the user needs to write, the electromagnetic pen is also suspended in a space within a certain range from the screen before the user holds the electromagnetic pen in contact with the screen, and the frequency of the electromagnetic signal is within the predetermined suspension frequency range. However, the floating time is short, and the possibility of frequent cursor shaking is low. If in this short period of time, the state of the electromagnetic pen is determined as the predetermined floating state only according to the frequency of the electromagnetic signal received by the electromagnetic board, the short time Then, the state of the electromagnetic pen is determined as the writing state according to the frequency of the electromagnetic signal received by the electromagnetic board, which will cause multiple switching of the touch resolution and cause unnecessary waste of resources.

In view of the above situation, in this embodiment of the present invention, the state of the electromagnetic pen can be judged according to the frequency of the electromagnetic signal received by the electromagnetic board for a period of time within a predetermined suspension frequency range. If the duration is higher than or equal to the first time threshold, it is determined that the electromagnetic pen is currently in a levitating state. The first time threshold mentioned here can be predetermined according to actual scene requirements, such as predetermined as 30ms or other values.

In addition, if the frequency of the electromagnetic signal received by the electromagnetic board is within a predetermined writing frequency range, it can be determined that the electromagnetic pen is in a writing state. In addition, if the frequency of the electromagnetic signal lasts for a time within the levitation frequency range and is lower than the first time threshold, it may also be determined that the electromagnetic pen is currently in a writing state.

In other embodiments, in addition to judging the state of the electromagnetic pen according to the frequency of the electromagnetic signal received by the electromagnetic board, the state of the electromagnetic pen may also be judged according to pre-generated pressure-sensitive data. In addition, if the electromagnetic board itself has a certain judgment ability, the electromagnetic board can also judge the state of the electromagnetic pen according to the frequency sensed by itself, and then inform the execution body to make a judgment. The processor 122 or the operating system 240 shown in FIG. 1B.

In addition, the state of the electromagnetic pen can also be determined by using the image captured by the camera, and the specific implementation can be implemented in various ways, which are not limited in this embodiment of the present invention.

In practical applications, the writing frequency range and the levitation frequency range can be pre-configured corresponding to the electromagnetic pen associated with the touch system, and then pre-stored in the storage space of the touch system corresponding to the electromagnetic pen. In other scenarios, there may be more than two electromagnetic pens operating on the screen at the same time. For example, in a classroom interactive teaching scenario, there may be multiple students who need to answer questions through the same screen at the same time. Therefore, the embodiments of the present invention can also target different electromagnetic pens. , and configure the writing frequency range and suspension frequency range corresponding to different electromagnetic pens, so as to distinguish the states of different electromagnetic pens. It should be emphasized that the intersection of different writing frequency ranges pre-stored corresponding to different electromagnetic pens is empty, the intersection of different pre-stored suspension frequency ranges is also empty, and the intersection of any writing frequency range and any suspension frequency range is also empty. When the touch position data is determined, the touch position data of different electromagnetic pens are also determined respectively for different electromagnetic pens.

As shown in Figure 2B, the electromagnetic pen A and the electromagnetic B are in contact with the display screen surface of the touch device respectively and are in the writing state. The electromagnetic board can receive the frequencies of the electromagnetic signals sent by the two electromagnetic pens respectively, and then report them to the touch device in the touch device. The touch control board is equipped with a touch control system, which is reported to the main chip in the host device when necessary, and the main chip is equipped with an operating system.

As shown in Figure 2C, the electromagnetic pen A and the electromagnetic B are suspended somewhere above the display screen surface of the touch device, and are in a predetermined floating state. The electromagnetic board can receive the frequencies of the electromagnetic signals sent by the two electromagnetic pens respectively, and then report To the touch motherboard in the touch device, the touch motherboard is equipped with a touch system, which is reported to the main chip in the host device when necessary, and the main chip is equipped with an operating system.

As described in the foregoing embodiments, in addition to determining the state of the electromagnetic pen according to the frequency of the electromagnetic signal sensed by the electromagnetic board, the state of the electromagnetic pen may also be determined in other ways, which are not limited in this embodiment of the present invention.

After the current state of the electromagnetic pen is determined, the touch data of the electromagnetic pen can be determined according to the corresponding working mode. If it is in the writing state, the touch data of the electromagnetic pen is determined according to the first working mode; if it is in the floating state, the touch data of the electromagnetic pen is determined according to the second working mode; the touch accuracy in the second working mode is lower than touch accuracy in the first working mode. The first working mode and the second working mode mentioned here can be implemented in multiple ways, two of which are listed below:

In the first type, the first working mode corresponds to the first touch resolution, the second working mode corresponds to the second touch resolution, and the second touch resolution is lower than the first touch resolution. Steps S201 and S202 can be implemented in the following ways:

generating touch position data in the touch data according to a predetermined first touch resolution;

Touch position data in the touch data is generated according to a second touch resolution lower than the first touch resolution.

It should be noted that the first touch resolution and the second touch resolution are similar to the display resolution of the screen, and represent the number of touch units in the screen. The difference is: the value of the first touch resolution A value greater than the second touch resolution. The first touch resolution and second touch resolution mentioned here can be set according to the display resolution of the display screen (associated display screen) included in the screen, for example, the first touch resolution is higher than or equal to the associated display screen The resolution of the second touch screen is lower than the resolution of the associated display screen.

The touch unit corresponding to the first touch resolution or the second touch resolution may be determined by the display resolution of the screen and the first touch resolution or the second touch resolution, for example: the display resolution of the screen is 3840×2160, the The first touch resolution is equal to the display resolution, which is 3840×2160, and the second touch resolution is smaller than the display resolution, which is 1920×1080. The touch unit corresponding to the first touch resolution is one pixel, and the touch unit corresponding to the second touch resolution is 4 pixels. In other examples, the first touch resolution and the second touch resolution may also be set to other values according to scene requirements, such as setting the first touch resolution to 2K or 4K, etc., which will not be repeated here.

Regarding the above-mentioned first touch resolution and second touch resolution, when specifically determining the touch position data, if the electromagnetic pen is currently in the writing state, first determine the position point that causes the magnetic flux change according to the magnetic flux change sensed by the electromagnetic board. The distance between the position point and the previously determined position point is less than or equal to the touch unit corresponding to the first touch resolution, then it is determined that the coordinates of the current position point are consistent with the coordinates of the previously determined position point, and the previous one can be used. The coordinates of the determined position point represent the current touch position data; if it is larger than the touch unit corresponding to the first touch resolution, the coordinates of the current position point can be used to represent the current touch position data.

If the electromagnetic pen is currently in a predetermined floating state, first, according to the magnetic flux change sensed by the electromagnetic board, the position point that causes the magnetic flux change, if the distance between the position point and the previously determined position point is less than or equal to the second touch resolution If the touch unit corresponding to the rate is selected, then it is determined that the coordinates of the current location point are consistent with the coordinates of the previously determined location point, and the coordinates of the previously determined location point can be used to represent the current touch location data. After the touch location data is determined Generate touch data and report it; or, give up generating the current touch position data or touch data, or give up reporting the generated touch data.

If it is larger than the touch unit corresponding to the second touch resolution, the current touch position data can be represented by the coordinates of the current position point, and the touch data is generated and reported after the touch position data is determined.

In addition, in the first implementation manner, the method for processing touch data can be applied to a touch control system or an operating system and executed by different execution subjects. In one example, the method of the present invention is applied to a touch control system mounted on a touch device, and further The following steps can be included:

The touch signal is sent to the touch device or to a virtual touch device for a touch response.

In some scenarios, specific reference may be made to the embodiment involved in FIG. 1B , which will not be repeated here.

Second, the touch resolutions corresponding to the first working mode and the second working mode are the same, and the touch position data can be generated according to the same predetermined touch resolution. The predetermined touch resolutions mentioned here may all be the aforementioned first touch resolutions, or touch resolutions of other values, which will not be repeated here.

However, after the touch position data is generated according to the predetermined touch resolution, in the first working mode, the generated touch position data is directly used as the current touch position data of the electromagnetic pen, and the touch data including the touch position data is determined as the touch position data of the electromagnetic pen. Touch Data.

In the second working mode, after the touch position data is generated, it is judged whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value; if it is greater, the generated touch position data is directly used as the current touch position data of the electromagnetic pen , determine that the touch data containing the touch position data is the touch data of the electromagnetic pen, if not greater than, discard the generated touch position data, determine that the touch data of the electromagnetic pen is empty, or determine that the touch data contains the previous touch The touch data of the position data is the touch data of the electromagnetic pen. Wherein, the predetermined distance value is greater than or equal to the distance value of adjacent touch units under the predetermined touch resolution.

In an example, after step S201, the method of the present invention further includes the following steps:

According to a predetermined touch resolution, the touch position data of the electromagnetic pen is generated. For details, reference may be made to the content involved in the foregoing embodiments, which will not be repeated here.

If it is greater than, determining that the touch data including the touch position data is the touch data of the electromagnetic pen;

If it is not greater than the value, the touch position data is discarded, the touch data of the electromagnetic pen is determined to be empty, or the touch data including the previous touch position data is determined to be the touch data of the electromagnetic pen.

Wherein, to determine whether the distance between the current position of the electromagnetic pen and its previous position is greater than a predetermined distance value, the judgment can be made according to the currently generated touch position data and the previously generated touch position data, or it can be judged according to the shooting time of the camera and the The motion trajectory of the photographed electromagnetic pen can also be judged by other means, which will not be repeated here.

In addition, in the second implementation manner, the method for processing touch data can be applied to a touch control system or an operating system and executed by different execution subjects. The following steps can be included:

Send the touch data of the electromagnetic pen to the operating system for touch response.

In some scenarios, specific reference may be made to the embodiment involved in FIG. 1A , which will not be repeated here.

In another example, the method of the present invention is applied to an operating system, and may further include the following steps:

In other embodiments, the first working mode and the second working mode can be implemented in other ways besides the aforementioned two implementations, as long as the touch accuracy in the first working mode is higher than that in the second working mode. The method will not be repeated here.

It can be seen from the above embodiment that the present invention can determine the touch data of the electromagnetic pen according to the first working mode when the electromagnetic pen is in the writing state by judging the current state of the electromagnetic pen; when the electromagnetic pen is in the floating state, according to the second operation mode. The working mode determines the touch data of the electromagnetic pen, and the touch accuracy corresponding to the determined touch position is lower than the touch accuracy in the first working mode in the writing state, so that the frequency of changes in the cursor position can be reduced, thereby reducing the cursor position as much as possible. frequent jitter to avoid unnecessary resource consumption.
