Fig. 1 is a schematic view of an application scenario of a touch data processing method in an exemplary embodiment of the present application, in the application scenario of fig. 1, the touch data processing method in the present application is applied to an intelligent device 100, the intelligent device 100 is an integrated device that performs control and realizes human-computer interaction operation on a display panel through a touch technology, and in an embodiment, the intelligent device 100 may be an intelligent interaction tablet. In other application scenarios, the touch data processing method according to the embodiment of the present application may also be applied to other intelligent devices, such as a computer, a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), an e-book reader, a multimedia player, and the like.
An operating system is loaded in the main control chip of the smart device 100, the operating system may include windows, android and the like, and the operating system is used for the smart device, and a touch driver is run on the operating system and used for responding to a touch signal generated by the touch device.
The intelligent Device 100 is equipped with a touch Device, the touch Device is an HID Device for implementing Human-computer interaction, and the HID is an abbreviation of Human Interface Device and belongs to a Device for Human-computer interaction operation, however, the HID Device does not necessarily need to have a Human-computer Interface, and as long as the devices conforming to the HID category specification are all HID devices. The touch device installed on the smart device 100 may be a combination of an infrared touch frame and an electromagnetic screen, or a combination of an electromagnetic screen and a capacitive screen.
The Electromagnetic screen refers to an Electromagnetic touch screen that can implement accurate touch and original handwriting writing by using an Electromagnetic induction technology (Electromagnetic response), and can implement touch only by being matched with an Electromagnetic pen, and is used for identifying touch operations, such as click operations, writing operations and the like, of a user on the Electromagnetic screen by using the Electromagnetic pen 200 as shown in fig. 1.
As an embodiment, the infrared touch frame works on the principle that infrared geminate transistors are distributed around a display screen of an intelligent device, the infrared geminate transistors comprise infrared receiving tubes and infrared transmitting tubes, the infrared geminate transistors are arranged on the surface of the display screen in a one-to-one corresponding position relationship to form an optical network formed by infrared light, and the optical network forms a positioning system. When an object (for example, a finger 300 in fig. 1, or other articles such as a writing pen) enters the infrared light net to block infrared light emission and reception at a certain position, the intensity of infrared light received by the infrared receiving pair tubes in the horizontal and vertical directions at the point changes, and the device can know the coordinate position of the contact point blocking the infrared light in the whole infrared touch frame by knowing the change of the infrared receiving condition.
The capacitive screen works by utilizing the current induction of a human body. When a finger 300 or other conductive object in fig. 1 touches the surface of the capacitive screen, a coupling capacitor is formed between the user and the surface of the capacitive screen due to the electric field of the human body, and for high-frequency current, the capacitor is a direct conductor, so that the finger 300 draws a small current from the contact point, the current flows out from the electrodes on the four corners of the capacitive screen respectively, the current flowing through the four electrodes is proportional to the distances from the finger to the four corners, and the position of the touch point is obtained by accurately calculating the proportions of the four currents.
According to the working principle of the touch device, when a user uses the electromagnetic pen 200 to perform touch operation on the display panel of the smart device 100, if the touch device installed in the smart device 100 is a combination of the infrared touch frame and the electromagnetic screen, the electromagnetic screen and the infrared touch frame detect input of touch data according to the touch operation of the electromagnetic pen, respectively, and if the touch device installed in the smart device 100 is a combination of the electromagnetic screen and the capacitive screen, although the capacitive screen does not detect input of touch data according to the touch operation of the electromagnetic pen, when the user uses the electromagnetic pen 200 to perform touch operation, fingers or palms of the user may erroneously touch the surface of the capacitive screen, so that the capacitive screen also detects input of touch data.
When the electromagnetic pen is used for writing, a user generally only needs touch data detected by the electromagnetic screen, so that the touch data generated by an infrared touch frame or a capacitive screen attached to the electromagnetic pen is separated when the electromagnetic pen is used for touch operation. The existing touch data separation method generally sets a touch data priority mode, for example, sets an electromagnetic touch data priority mode, in which the smart device 100 receives inputs of two types of touch data generated by an infrared touch frame and an electromagnetic screen, or an electromagnetic screen and a capacitive screen from a touch device at the same time, and only responds to the touch data generated by the electromagnetic screen, but not responds to the touch data generated by the infrared touch frame or the capacitive screen.
As shown in fig. 2A, fig. 2A is a schematic diagram of a touch recognition area of a display screen of a smart device in an example, where the recognition area of an infrared touch frame is 3mm above the display panel, and the recognition area of an electromagnetic screen is 10mm above the display panel, and in an ideal situation, the electromagnetic screen recognizes an electromagnetic pen preferentially over the infrared touch frame.
As shown in fig. 2B, in practical applications, if the flatness of the display panel of the smart device is not good, the infrared touch frame may recognize the electromagnetic pen before the electromagnetic screen, and at this time, the infrared touch frame may generate touch data earlier than the electromagnetic screen.
In other applications, the speed of writing with the electromagnetic pen and the speed of uploading touch data by different touch devices may also cause the smart device 100 to respond to the touch data generated by the infrared touch frame or the capacitive screen due to the touch operation before receiving the touch data generated by the electromagnetic screen when the user uses the electromagnetic pen for touch operation.
As shown in fig. 3, fig. 3 is a schematic diagram illustrating a writing effect when the smart device 100 preferentially recognizes touch data generated by the infrared touch frame in a process of responding to a touch signal, in fig. 3, a user performs a writing operation using an electromagnetic pen to draw a line 400, and since the touch data generated by the infrared touch frame is preferentially recognized, before recognizing the touch data generated by the electromagnetic screen, a front end 410 of the line 400 is written in response to the touch data generated by the infrared touch frame, and in an actual application, colors or thicknesses of the front end 410 and other portions of the line 400 may not be the same, so that the current writing operation may be broken and writing may not be smooth.
In order to solve the technical problem, an embodiment of the present application provides a touch data processing method, which may be executed by a touch data processing unit provided by the intelligent device 100, where the touch data processing unit may be implemented in a software and/or hardware manner and may be integrated in a main control chip of the intelligent device 100, and the touch data processing unit is connected to a touch device through a signal input/output interface, receives and processes touch data generated by the touch device, and sends the processed data to an operating system of the intelligent device 100. As shown in fig. 4, in an exemplary embodiment, the touch data processing method includes the steps of:
step S401: first touch data generated by a first touch device is received, wherein the first touch data comprises a first touch position signal.
The first touch device is a capacitive screen or an infrared touch frame, and the first touch data is touch data generated by the infrared touch frame when a user performs touch operation through a finger, a writing pen or other objects, or touch data generated by the capacitive screen when the user performs touch operation through the finger or other conductive objects.
When the first touch device detects a touch operation of a user, the generated first touch data includes a touch position signal of the touch data in the first touch device, and generally, the touch position signal is a coordinate signal of each touch point.
Step S402: and caching the first touch data, and recording the caching progress.
The complete touch data generally includes an initial touch state, a touch moving or sliding state and a touch lifting state of a touch point, the initial touch state is a state when a touch signal is initially generated, and the touch point corresponding to the initial touch state is an initial touch point.
In an example, as shown in table 1 below, when the first touch device is an infrared touch frame, the infrared touch frame reports the generated touch data through a message shown in the following table. In table 1, a plurality of sets of touch Data are shown, for a first set of touch Data, Point1 Data is a starting touch Point of the touch Data, and Point Data is a last touch Point of the touch Data when a touch-up state is detected.
Figure GDA0003398899100000071
TABLE 1
In the embodiment of the application, after the first touch data is received from the first touch device, the first touch data is not directly sent to the operating system for response, but the first touch data is cached.
The cache processing refers to caching data, and the cache processing may be performed by a special processor, where the processor stores the data in a cache region of the processor, or the processor sends the data to a cache memory or a cache region of a memory to perform cache processing during processing, in a specific example, the first touch data is cached in such a manner that the first touch data is stored in the cache region of the processor from a start touch point of the first touch data, and since the sequence of reading the data by the processor is to read the cached data first and then the data in the memory, the subsequent processing of the first touch data can be performed more quickly.
After the caching process is started, recording the caching progress, wherein the caching progress reflects the progress degree of caching the first touch data in real time.
Step S403: and when the cache progress meets a preset trigger condition, detecting whether second touch data generated by a second touch device is received currently, wherein the second touch data comprises a second touch position signal.
According to the embodiment of the application, whether the preset triggering condition is met or not is judged according to the cache progress, the preset triggering condition is a triggering condition preset according to the cache progress, and when the cache progress reaches the preset value, the preset triggering condition can be triggered.
The second touch device is an electromagnetic screen, and the second touch data is touch data generated by the electromagnetic screen when a user performs touch operation through an electromagnetic pen.
When the second touch device detects a touch operation of a user, the generated second touch data includes a touch position signal of the touch data in the second touch device, and generally, the touch position signal is a coordinate signal of each touch point.
Step S404: and when the second touch data is received, determining whether the distance between the first touch position signal and the second touch position signal is smaller than a preset distance threshold value.
After receiving the first touch data, it is necessary to determine whether the first touch data is generated by writing with an electromagnetic pen that generates the second touch data, and if so, the initial touch points of the first touch data and the second touch data should coincide or have relatively close distances.
The distance between the first touch signal and the second touch signal may be calculated in various ways, and may have different expressions, for example, the distance may be a straight-line distance between the first touch position signal and the second touch position signal, or whether the distance is within a preset coordinate range of the first touch position signal, or whether the distance is within a preset coordinate range of the second touch position signal. Correspondingly, the preset distance threshold may be a specific straight-line threshold Δ d, or may be a coordinate threshold (Δ X, Δ Y). In a more preferred example, the distance between the first touch position signal and the second touch position signal is calculated by a distance between a position of a start touch point of the first touch position signal and a start touch point of the second touch position signal, or whether the start touch point of the second touch position signal is in a preset coordinate range of the start touch point of the first touch position signal, or whether the start touch point of the first touch position signal is in a preset coordinate range of the start touch point of the second touch position signal.
For example, if the initial touch point coordinate of the first touch data is (X)Ir down，YIrdown), the initial touch point coordinate of the second touch data is (X)EMR down，YEMRdown), if the coordinate is (X)Ir down，YIrdown) falls on (X)EMRdown±ΔX，YEMRdown ± Δ Y), it may be determined that a distance between the initial touch point of the first touch data and the initial touch point of the second touch data is smaller than a preset distance threshold, where Δ X and Δ Y are preset coordinate thresholds.
As shown in fig. 5, fig. 5 illustrates two cases where a distance between a start touch point of infrared touch data and a start touch point of electromagnetic touch data is smaller than a preset distance threshold, in fig. 5, a first start touch point is the start touch point of the infrared touch data, a second start touch point is the start touch point of the electromagnetic touch data, and in fig. 5, the start touch point of the infrared touch data and the start touch point of the electromagnetic touch data are smaller than the preset distance threshold, it may be determined that the first touch data and the second touch data are generated by touch operations of the same electromagnetic pen.
Step S405: when the distance between the first touch position signal and the second touch position signal is smaller than the preset distance threshold, discarding the first touch data, and transmitting the second touch data to an operating system, so that the operating system responds based on the second touch data.
Discarding the first touch data means not performing subsequent processing on the first touch data, that is, not sending the first touch data to the operating system of the smart device, so that the operating system of the smart device does not respond to the touch operation of the first touch data, but only responds to the touch operation of the second touch data.
When the distance between the first touch position signal and the second touch position signal is smaller than a preset distance threshold, it is indicated that the first touch data and the second touch data may be generated by touch operation of the same electromagnetic pen, and the first touch data is generated by mistaken touch of a finger in the process of operating the electromagnetic pen, and the first touch data is discarded.
In the embodiment of the application, after first touch data generated by a first touch device is received, caching the first touch data, after the caching progress meets a preset trigger condition, detecting whether second touch data is received, and when the second touch data is received and the distance between the second touch data and the first touch data is smaller than a preset distance threshold, discarding the first touch data, so that separation of two types of touch data generated simultaneously when a writing pen is used for touch operation is effectively realized, and situations of line breaking during writing, unsmooth writing and the like caused by error shielding of one type of touch data are avoided.
In addition, in one embodiment, when the distance between the first touch position signal and the second touch position signal is greater than or equal to the preset distance threshold, the first touch data and the second touch data are respectively transmitted to an operating system, so that the operating system respectively responds based on the first touch data and the second touch data.
In other words, in this case, the first touch data and the second touch data are not generated by touch operations of the same electromagnetic pen, the first touch data are not generated by erroneous touch during operation of the electromagnetic pen, and the first touch data and the second touch data are respectively transmitted to the operating system, so that simultaneous processing of the two touch data can be realized, and simultaneous responses of the smart device to the two touch data can be realized.
In another embodiment, if the second touch data is not received, the first touch data is transmitted to an operating system, so that the operating system responds based on the first touch data, and therefore the response of the infrared touch frame or the capacitive screen to other touch operations is realized during the non-electromagnetic pen touch operation.
In some examples, when the writing device is an electromagnetic pen, the second touch data further includes a touch pressure signal, and the operating system responds to the second touch data by: and the operating system displays writing handwriting on a display screen of the intelligent device according to the touch pressure signal and the second touch position signal, and determines the thickness of the writing handwriting according to the value of the touch pressure signal.
When the user writes and presses the pen point of the electromagnetic pen, the electromagnetic pen transmits the touch pressure signal to a second touch device, namely an electromagnetic screen, and the second touch device takes the touch pressure signal and a second touch position signal as contents in second touch data and sends the contents together to the touch data processing unit of the intelligent device for processing.
The response of the operating system of the intelligent device to the writing operation of the electromagnetic pen is usually according to the touch position of the electromagnetic pen, and the writing handwriting is correspondingly generated on the display panel of the intelligent device.
In some other examples, the first touch data further includes a touch point area value, and the operating system responds to the first touch data by:
and the operating system displays writing handwriting on a display screen of the intelligent device according to the touch point area value and the first touch position signal, and determines the thickness of the writing handwriting according to the size of the touch point area value.
The operating system responds based on the first touch data, and the response mode is determined based on a specific application scene, for example, when the application scene is a whiteboard, the response is to display writing handwriting according to the first touch data, and when the application scene is other, the response can be corresponding other touch operations, such as clicking, dragging, and an eraser function.
In this embodiment, the first touch device further detects an area of a touch point where a writing device (a finger, a writing pen, or other articles) contacts a display panel of the smart device, and the first touch device uses the area value of the touch point and the first touch position signal as contents in the first touch data, and sends the contents to the touch data processing unit of the smart device for processing, so that the thickness of the written handwriting can be determined according to the size of the touch pressure signal value in a writing scene, and the writing effect can be determined according to the requirements of a user.
Based on the data format of the first touch data, in an example, the first touch data is cached by sequentially storing the first touch data into a cache region from a start touch point of the first touch data, so that the caching progress can be determined more accurately.
After the preset trigger condition is met, the first touch data is transmitted to an operating system, where the method may be: and sequentially outputting the cached first touch data from the cache region, wherein the frequency of outputting the first touch data from the cache region is greater than the sampling frequency of the first touch device for the first touch data.
Since the first touch data may be continuously input from the first touch device to the touch data processing unit, the first touch data stored in the buffer needs to be quickly sent to the operating system for subsequent response to the fluency of the first touch data, and therefore, the frequency of the first touch data output from the buffer is greater than the sampling frequency of the first touch data. The sampling frequency of the first touch data is the frequency of reporting the first touch data by the first input device, for example, if the reporting frequency is 8ms to update one data, the output of the buffered first touch data from the buffer may be 6ms, 4ms, or 2 ms.
According to the embodiment of the application, the processed data is processed quickly, so that delay of a subsequent operating system responding to the first touch data is avoided.
In one example, the cache progress includes a cache time and/or a cache data amount, and the preset trigger condition includes:
whether the caching time reaches a first threshold value and/or whether the caching data amount reaches a second threshold value.
When the first touch data is generated in a scene where a user quickly clicks and lifts, if the first touch data is infrared touch data and the reporting frequency of the infrared touch data is, for example, 8ms to update one piece of data, the cache progress may be cache time, and the preset trigger condition may be to determine whether the cache time reaches a first threshold, specifically, the next step of determining whether the second touch data input by the second touch device is currently received may be performed by starting timing with a timer when the first touch data is stored in the cache region, and meeting the preset trigger condition when the timing time reaches the first threshold, for example, 50 ms. In some examples, the timer restarts timing each time a new start touch point of the first touch data is received.
In another example, if the first touch data is generated in another scenario with a large data volume, such as writing, the caching progress may be the cached data volume, and the preset trigger condition may be to determine whether the cached data volume reaches a second threshold. The specific implementation may be that the first touch data is stored in the buffer area, the counter starts to count, and when the amount of the buffered data reaches a second threshold, for example, 6 data, a preset trigger condition is met, and a next operation of determining whether the second touch data input by the second touch device is currently received is performed. In some examples, the counter restarts counting each time a starting touch point of new first touch data is received.
In other examples, in the determination process, the two cache schedules may also be determined simultaneously, and the relationship in the determination process may be "or", that is, any cache schedule satisfies the preset trigger condition, or "and", that is, when both cache schedules satisfy the preset trigger condition, the preset trigger condition is satisfied.
In the embodiment of the application, different caching schedules are set to meet different triggering conditions, and the separation of hand touch signals and pen touch signals in different application scenes is achieved.
In one example, determining whether the distance between the first touch position signal and the second touch position signal is less than a preset distance threshold comprises: and determining whether the distance between the initial touch point of the first touch position signal and the initial touch point of the second touch position signal is smaller than a preset distance threshold value, so that whether the first touch data is adjacent to the second touch data can be more accurately judged.
In the scenario shown in fig. 6, the touch device installed in the smart device 600 is a combination of an infrared touch frame and an electromagnetic screen, in the scenario shown in fig. 7, the touch device installed in the smart device 600 is a combination of a capacitive screen and an electromagnetic screen, and in fig. 6 and 7, the application program run by the smart device 600 is a writing application program, that is, a way in which an operating system of the smart device 600 responds to touch data generated by the infrared touch frame or the capacitive screen, is to display handwriting on the display panel.
In fig. 6, a user a and a user B perform touch operations at different portions of a display panel of the smart device 600 at the same time, where the user a performs writing operations using an electromagnetic pen, and the user B performs writing operations using hands.
As shown in fig. 8, for the scenario in fig. 6, the touch data processing unit in the embodiment of the present application performs the following operations for the touch data generated by writing by the user a:
step S801: receiving first infrared touch data a1 generated by the infrared touch frame, wherein the first infrared touch data a1 comprises a first infrared touch position signal and a first touch point area value.
The first infrared touch data a1 is touch data generated by the infrared touch frame in response to a writing operation of a user a, and in fig. 6, the first infrared touch data a1, the second infrared touch data b1 and the electromagnetic touch data a2 are schematic positions of touch data generated by a touch device in a display panel.
Step S802: and starting from the initial touch point a11, performing caching processing on the first infrared touch data a1, and recording the caching progress.
Step S803: when the caching progress meets the preset triggering condition, for example, the cached data amount reaches 8, which are a11 to a18, respectively, whether the electromagnetic touch data a2 generated by the electromagnetic screen is received is detected, wherein the electromagnetic touch data a2 includes an electromagnetic touch position signal and a touch pressure signal.
Step S804: when the electromagnetic touch data a2 is received, it is determined whether a distance between the position of the start touch point a11 and the position of the start touch point a21 of the electromagnetic touch data is less than a preset distance threshold.
As shown in fig. 6, since the first infrared touch data a1 and the electromagnetic touch data a2 are generated according to the writing operation of the user a, the position between the start touch point a11 of the first infrared touch data and the start touch point a21 of the electromagnetic touch data is close to be less than the preset distance threshold.
For example, if the coordinates of the start touch point of the first infrared touch data are (a11, a12) and the coordinates of the start touch point a2 of the electromagnetic touch data are (a21, a22), it may be determined whether the distance between the two coordinates is less than the preset distance threshold.
Step S805: when the distance between the initial touch point position a11 and the initial touch point position a21 of the electromagnetic touch data is smaller than the preset distance threshold, discarding the first infrared touch data a1, and transmitting the electromagnetic touch data to an operating system, so that the operating system displays writing on a display screen of the intelligent device, and determining the thickness of the writing according to the size of the touch pressure signal value.
As shown in fig. 9, the touch data processing unit in the embodiment of the present application performs the following operations on touch data generated by writing by the user B:
step S901: receiving second infrared touch data b1 generated by the infrared touch frame, wherein the second infrared touch data b1 comprises a second infrared touch position signal and a second touch point area value.
Wherein the second infrared touch data B1 is touch data generated by the infrared touch box responding to the writing operation of the user B.
Step S902: b11, starting from the initial touch point, performing buffer processing on the second infrared touch data b1, and recording the buffer progress.
Step S903: when the caching progress meets the preset triggering condition, detecting whether electromagnetic touch data a2 generated by the electromagnetic screen is received, wherein the electromagnetic touch data a2 comprises an electromagnetic touch position signal and a touch pressure signal.
Step S904: when the electromagnetic touch data a2 is received, it is determined whether the distance between the position of the start touch point b11 and the position of the start touch point a21 of the electromagnetic touch signal is less than a preset distance threshold.
As shown in fig. 6, since the second infrared touch data B1 and the electromagnetic touch data a2 are generated according to writing operations of the user B and the user a, respectively, a distance between the position of the start touch point B11 of the second infrared touch data and the position of the start touch point a21 of the electromagnetic touch data is far greater than the preset distance threshold.
Step S905: when the distance between the position of the initial touch point B11 and the position of the initial touch point a21 of the electromagnetic touch signal is larger than the preset distance threshold, the second infrared touch data B1 and the electromagnetic touch data a2 are respectively transmitted to an operating system, so that the operating system respectively displays writing scripts of a user A and a user B on a display screen of the intelligent device, the thickness of the writing script of the user A is determined according to the value of the touch pressure signal, and the thickness of the writing script of the user B is determined according to the value of the area of the second touch point.
Regarding the scenario in fig. 7, the touch data generated by the touch data processing unit in the embodiment of the present application for writing by the user a and the touch data generated by writing by the user B are substantially the same as the above-mentioned flows in fig. 8 and fig. 9, and the main difference is that the touch data generated by the capacitive screen in response to the writing by the user a is generated by touching the capacitive screen by mistake by a finger or a palm of the user a, and the position of the touch data is larger than the position of the touch data generated by the electromagnetic screen in response to the writing operation by the user a, so in the scenario in fig. 7, the preset distance threshold needs to be larger than the distance between the palm of the user and the pen tip of the electromagnetic pen.
According to the touch data processing method, when the electromagnetic pen is used for writing on the condition that the touch device of the user A is the combination of the infrared touch frame and the electromagnetic screen or the combination of the capacitive screen and the electromagnetic screen, touch data generated by the infrared touch frame or the capacitive screen responding to the writing and touch data generated by the electromagnetic screen responding to the writing are effectively separated, so that the writing of the user A cannot be broken, unsmooth and the like, meanwhile, the common response of the intelligent device to touch operations of the user A and the user B is realized, and the writing handwriting of the user B of the user A is displayed on the display panel at the same time.
