Technical field

The present invention relates to data processing technologies, and in particular, to a method, device, device and storage medium for separating touch data.

Background technique

A general interactive intelligent terminal has a touch function, such as a smart whiteboard or a smart conference tablet used in a classroom. The hardware components used in such a terminal product are usually an infrared touch frame, an electromagnetic screen, and a capacitive screen. In order to support a more detailed writing experience, a combination of electromagnetic screen and capacitive screen, or a combination of an infrared touch frame and an electromagnetic screen is often used. Among them, the electromagnetic screen only supports the writing of the electromagnetic pen, while the capacitive screen and the infrared touch frame both support the hand touch, and the infrared touch frame also supports the touch of the non-transparent object.

Regardless of the combination method described above, when both the hand and the pen exist, the writing application receives two kinds of reported data, one type of pen touch data, one type of hand touch data, and the two types of data are for the same physical touch. The control points are generated, and because the electromagnetic screen and the capacitive screen (or the electromagnetic screen and the infrared touch frame) have different sensing precisions, the numerical deviation is caused, so that the writing is broken or not smooth.

In the prior art, different types of data are usually distributed in a time-sharing manner, and only one type of data exists at a time, which has high requirements on hardware design, and additional delay time is added for each type of data.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.

Embodiment 1

FIG. 1 is a flowchart of a method for separating touch data according to Embodiment 1 of the present invention. The present embodiment is applicable to a case where at least two kinds of touch data need to be separated, such as a touch screen or a touch panel, and the method can be implemented by the present invention. For example, a touch data separation device is provided, which can be implemented by software and/or hardware, and can be integrated into a terminal device with touch function, such as a smart whiteboard for classrooms, a smart conference tablet, etc. . Referring to FIG. 1a, the method may specifically include the following steps:

S110. Determine a type of touch data of the touch point at the current time. If the touch data is at least two different types, the touch data is filtered according to the current application mode.

Wherein, when the hand and the pen act on the touch component at the same time, the pen touch data and the hand touch data are simultaneously generated, and the current data type is first identified. Optionally, the touch component is usually an infrared touch frame, an electromagnetic screen, and a capacitive screen. In order to increase the detailed writing experience, a combination of an electromagnetic screen and a capacitive screen, or an infrared touch frame and an electromagnetic screen are generally used. The electromagnetic screen only supports the writing and touch click of the electromagnetic pen, that is, the pen touch data is generated by the electromagnetic screen, and the capacitive screen and the infrared touch frame both support the hand touch, that is, the hand touch data is generated by the capacitive screen or the infrared touch frame.

Infrared touch data is represented by IR, where IR is an abbreviation of Infrared Radiation, and electromagnetic pen touch data is represented by EMR, where EMR is an abbreviation of Electromagnetic Radiation. FIG. 1b shows a two-type touch data time-sharing distribution mechanism in the prior art. As shown in FIG. 1b, t represents time. In the prior art, different types of touch data are distributed by time sharing, that is, each time exists. One type of touch data does not require filtering, and each type of touch data has an additional delay time. For example, if there is purely infrared touch data, the transmission time occupied by the additional electromagnetic pen touch data is increased between adjacent two infrared touch data (although there is actually no electromagnetic pen writing). Figure 1c shows a two-type touch data concurrency and separation mechanism. As shown in Figure 1c, t represents time, 150 represents infrared touch data, and 160 represents electromagnetic pen touch data. The two types of touch data are completely independent.

Specifically, the type of the touch data of the touch point at the current time is recognized. If the touch data is at least two different types, for example, the hand touch data and the pen touch data exist at the same time, the touch data is filtered according to the current application mode. . Optionally, the current application mode includes a priority preemption mode and a non-preemptive preemption mode.

S120. Determine whether the touch data meets a preset touch protocol rule. If not, execute S130, and if yes, perform direct filtering.

The preset touch protocol conforms to the standard reporting protocol rule, and the standard reporting protocol rule provides a protocol that the complete data packet should follow, that is, the data packet corresponding to each type of time is constructed by referring to the protocol, and the data not constructed by referring to the protocol is constructed. The package is not a complete packet and cannot be responded properly. In this solution, the data packet refers to a data packet of the touch data, and determines whether the touch data meets the preset touch protocol rule. If not, the method S130 is performed; if yes, the touch data is directly filtered according to the current application mode. .

S130. Replenish the touch data according to the preset touch protocol rule.

Specifically, the touch data of the current time is analyzed according to the preset touch protocol rule, and it is determined whether the touch data meets a preset touch protocol rule, and the touch data that needs to be replenished at the next moment is determined according to the rule.

The touch data is reissued according to the touch data that needs to be reissued to ensure the integrity of the touch data under the preset touch protocol rule, and provides guarantee for the transmission and response of the touch data.

Based on the above embodiment, the method for separating touch data further includes: acquiring a touch state of each touch point.

Wherein, the touch state of each point on the touch screen is related to the operation of the user, and when the touch data is detected, the touch state of each touch point is acquired. For each touch point, the touch state at the current time is different, resulting in different touch data, and then determining the touch data that needs to be reissued at the next moment according to the preset touch protocol rule may also be different.

Embodiment 2

FIG. 2 is a flowchart of a method for separating touch data according to Embodiment 2 of the present invention. On the basis of the foregoing embodiment, this embodiment optimizes “filtering touch data according to a current application mode”. Referring to FIG. 2, the method may specifically include the following steps:

S210: Determine a type of the touch data of the touch point at the current time. If the touch data is at least two different types, if the current application mode is the priority preemption mode, and the current touch data is detected as the first touch data, Whether the data type of the second touch data generated in the first preset time is the same as the data type of the first touch data, and if not, filtering the second touch data.

The following is an example in which the type of the touch data is two different types. When the current application mode is the priority preemption mode, when the current touch data is detected as the first touch data, the first generated time is determined. Whether the data type of the two touch data is the same as the data type of the first touch data. If they are different, the second touch data is filtered. If they are the same, the determination is continued. It should be noted that when the data types of the touch data are different, the data content of the touch data is different, and the second touch data and the first touch data include two cases, the types of the touch data are different, and the content of the touch data is different. In the present solution, comparing the data type of the second touch data with the data type of the first touch data, that is, when the data type of the second touch data is different from the data type of the first touch data, the second touch The data is filtered.

The data type of the first touch data includes a pen touch data type or a hand touch data type, and the data type of the second touch data includes a pen touch data type or a hand touch data type, and the priority touch mode preferentially responds to the current touch data.

In a specific example, the first touch data includes pen touch data or hand touch data, and the second touch data includes pen touch data or hand touch data, when the first touch data is pen touch data, and is at a first preset time When the second touch data generated in the hand is the hand touch data, the opponent touch data is filtered. The first preset time may be the duration of the touch data, that is, the touch status mark time, and the specific marking method will be described in detail later.

The specific application scenario may be that, for example, the electromagnetic pen first performs a touch operation, and when the current touch data is detected as the electromagnetic pen touch data, the subsequent hand touch data is filtered; for example, the hand first performs a touch operation, and the current touch data is detected as When the hand touches the data, the subsequent electromagnetic pen touch data is filtered. Optionally, when the original operation mode is stopped, the subsequent operation mode can rob the priority. The scenario may be that the currently detected touch data is pen touch data, and the detected data is exceeded after the first preset time. When the data is touched by the hand, the hand touch operation grabs the priority, that is, the pen touch operation has stopped.

Exemplarily, the following describes the marking and filtering of touch data in the priority preemption mode. For a clear description, the touch data is first defined. The touch data generated by the electromagnetic pen touch operation is defined as P touch data, and the touch data generated by the hand touch operation is defined as H touch data, wherein the P touch data and the H touch data conform to the standard universal touch protocol.

(1) If the current P touch data is generated, the mark currently has an electromagnetic pen in use. If only the electromagnetic pen is currently marked for use, the recording electromagnetic pen is the priority preemptor, and no touch data filtering is performed; if the hand has been marked for use, it is further determined that if the hand is the marked priority preemptor, then The P touch data is filtered; if the electromagnetic pen has been marked as a priority preemptor, the H touch data is filtered; in other cases, no touch data is filtered.

(2) If the current H touch data is generated, the mark is currently used by the hand touch. If only the hand is currently marked for use, the record hand is the priority preemptor and no touch data filtering is performed; if the currently existing electromagnetic pen is marked for use, it is further determined that if the electromagnetic pen has been marked as a priority preemptor, then Filter touch data; if the hand has been marked as a priority preemptor, the P touch data is filtered; in other cases, no packets are filtered.

(3) Other conditions do not filter any package

S220. Determine whether the touch data meets a preset touch protocol rule. If not, execute S230, and if yes, perform direct filtering.

S230: Re-issue the touch data according to the preset touch protocol rule.

In the embodiment of the present invention, when the current application mode is the priority preemption mode, if the current application mode is the priority preemption mode, and the current touch data is detected as the first touch data, determining the first generated time in the first preset time. Whether the data type of the two touch data is the same as the data type of the first touch data, and if not, filtering the second touch data. The filtering of data in the priority preemption mode is implemented.

Embodiment 3

FIG. 3 is a flowchart of a method for separating touch data according to Embodiment 3 of the present invention. On the basis of the foregoing embodiment, the present embodiment optimizes “filtering touch data according to a current application mode”. Referring to FIG. 3, the method may specifically include the following steps:

S310. Determine a type of the touch data of the touch point at the current time. If the touch data is at least two different types, if the current application mode is the first non-preemptive preemption mode, the first touch data and the second touch data are detected. The second touch data is filtered when the current application mode is the second non-preemptive preemption mode, and when the first touch data and the second touch data are detected to exist at the same time, the first touch data is filtered.

Specifically, the second non-preemptive preemption mode is to filter the second touch data when the first touch data and the second touch data exist simultaneously; the second non-preemptive preemption mode is The first touch data is filtered when the first touch data and the second touch data are simultaneously present.

In a specific example, when the first touch data is pen touch data, the second touch data is hand touch data, the hand touch data is filtered in the first non-preemptive preemption mode, and the pen is filtered in the second non-preemptive preemption mode. Touch the data.

Exemplarily, the following describes the marking and filtering of touch data in the non-preemptive preemptive mode. For the sake of clear description, the definitions of the P touch data and the H touch data are still described above, and the current non-preemptive preemption mode is used as the filtering H touch data as an example.

(1) If the current P touch data is generated, the mark currently has an electromagnetic pen in use. If only the electromagnetic pen is currently in use, no touch data packets are filtered; if there is currently a hand in use, the H touch data is filtered; in other cases, no touch data is filtered.

(2) If the current H touch data is generated, the mark is currently in use. If only the hand is currently in use, no touch data is filtered; if the current electromagnetic pen is currently in use, the H touch data is filtered; in other cases, no touch data is filtered.

S320. Determine whether the touch data meets a preset touch protocol rule. If not, execute S330. If yes, perform direct filtering.

S330. Replenish the touch data according to the preset touch protocol rule.

In the embodiment of the present invention, when the current application mode is the non-preemptive preemption mode, where the non-preemptive preemption mode includes the first non-preemptive preemption mode and the second non-preemptive preemption mode, the filtering is performed in the first non-preemptive preemption mode. The second touch data filters the first touch data in the second non-preemptive preemption mode. Filtering of touch data in non-preemptive preemption mode is implemented.

Embodiment 4

FIG. 4a is a flowchart of a method for separating touch data according to Embodiment 4 of the present invention. On the basis of the foregoing embodiment, this embodiment re-sends the touch data according to the preset touch protocol rule. "Optimized." Referring to FIG. 4a, the method may specifically include the following steps:

S410. Acquire a touch state of each touch point.

Optionally, the touch state of the touch point includes: a touch state, a touch lift state, and a touch pending state information.

Among them, the key to data re-issue is to track and count each touch point. Generally, the touch status of each touch point can be represented as a set {ID, STATUS}, where STATUS ∈ {DOWN, UP, MOVE}, ID is Is short for IDENTIFY, uniquely identifies a touch point; STATUS indicates the status of each touch point. The DOWM is a touch state, that is, a pressed state, for example, a user's finger presses the first touch point of the touch device; UP is a touch lift state, for example, the user's finger leaves the first touch point of the touch device; MOVE is a touch The pending state, that is, the moving and/or sliding state, for example, the user's finger moves from the first touch point of the touch device to the second touch point. Wherein, the touch state is that the hand or the electromagnetic pen touches or presses on the touch point, the touch lift state is the hand or the electromagnetic pen leaves the touch point, and the touch pending state is the hand or the electromagnetic pen moves and/or slides from a touch point to The transition state of another touch point.

Optionally, the touch up state is: when the touch data is detected, the mark touch data is being used, determining whether the touch data can be detected after the second preset time, and if yes, continuing to determine the first Whether the touch data can be detected after the preset time, until the touch data cannot be detected, marking the state as a touch-up state; wherein the second preset time is greater than generating the touch data cycle.

Wherein, when the touch data is detected, the touch data is being used, and whether the touch data can be detected after the second preset time is determined. Optionally, the second preset time may be a timing period, and the specific period value may be According to the type of touch data and user habits, there is no limit here. The state is marked as a touch-up state until the touch data cannot be detected. It should be noted that the carrier of the touch data is in the touch device, and the touch data is being used, that is, the touch device is being used. A specific example may be that the user's finger presses the touch screen of the touch device.

Next, the marking method of the opponent's use state is described. It is assumed that the period of the touch data generated by the hand touch is T _h . Figure 4b shows a hand touch status marking method, as shown in Figure 4b, t represents time and 460 represents H touch data. The time at which the first hand touch generates the touch data is T _hs , the start timer period is T _h-up , and T _h <T _{h-up is} satisfied. When the H touch data is generated, the mark hand touch is used, and the timer is reset. After re-clocking, the cycle is still T _h-up . When the timer overflows, the marker hand touch is raised. Specifically, at point A, the hand touch data is generated, the marker hand touch is used, the timing is started, and the timing period is T _h-up . At the time point B, it is detected that there is still hand touch data generated, and then the timing is re-timed. If there is still hand touch data generated at the time of the cycle, the retiming is continued. As indicated by point C, until the timing cycle is reached, the detected hand touch data is no longer generated. As indicated by point D, the hand touch usage flag is canceled.

Similarly, the marking method of the state of use of the electromagnetic pen is similar, and a brief description will be given below. It is assumed that the period of the touch data generated by the electromagnetic pen touch is T _p . Figure 4c shows a hand touch status marking method, as shown in Figure 4c, t represents time and 470 represents P touch data. The moment when the first electromagnetic pen touch generates touch data is T _ps , the start timer period is T _p-up , and T _p <T _{p-up is} satisfied. When the P touch data is generated, the mark electromagnetic pen touch is in use, and the timing is reset. Reclocked, the cycle is still T _h-up . When the timer overflows, the marker stylus touch has been raised. Specifically, at point E, the electromagnetic pen touch data is generated, the marking electromagnetic pen touch is used, the timing is started, the timing period is T _h-up , and at the time of point F, when the pen touch data is detected, the timing is re-timed and timed. If there is still electromagnetic pen touch data generated at the timing cycle, continue to re-timing, as indicated by G point, until the timing cycle is reached, the electromagnetic pen touch data is no longer generated, as shown by point I, the electromagnetic is canceled. The pen touch uses a marker.

In a specific example, in the priority preemption mode, the pen and the hand should be in a state of fair competition, and T _p-up =T _{h-up can be taken} ; in the non-preemptive preemption mode, the pen is in absolute priority. When you need to meet T _p-up >T _h-up .

S420: Determine a type of touch data of the touch point at the current time. If the touch data is at least two different types, the touch data is filtered according to the current application mode.

S430. Determine whether the touch data meets a preset touch protocol rule. If not, execute S440. If yes, perform direct filtering.

S440. For each touch point, if the last touch state of the touch point is a touch state or a touch pending state, the touch corresponding to the touch lift state of the touch point is reissued according to the preset touch protocol rule. Data information.

For example, if a touch point is a touch state or a touch pending state, that is, MOVE or DOWN, the touch lift state corresponding to the touch point is reissued according to the report protocol. Touching the data information, that is, replenishing the touch data corresponding to the UP event; if the previous state of the point is the touch state, that is, the UP state, the data is not re-issued and directly filtered. Optionally, the touch data corresponding to each type of event is constructed by referring to the reporting protocol.

Next, the concept of data reissue is explained. When the electromagnetic pen and the hand act on the touch component at the same time, wherein the touch component is an infrared touch frame, an electromagnetic screen or a capacitive screen, the generated touch data and the reported touch data are Very frequent (generally in milliseconds). Therefore, simply starting to filter out the touch data generated by the hand touch at a certain moment, so that the data reported to the system is not completely following the touch protocol, then there may be a problem of missing the reported touch event (such as a touch up event). Causes the system to touch abnormally. Therefore, it is necessary to track and count the state generated by each touch point, and at the time of preparing to filter the data, the touch data that needs to be replenished at the next moment is decided. Replenishing the touch data according to the touch data that needs to be reissued.

In the embodiment of the present invention, the touch state of each touch point is tracked and the touch state is determined. If the last touch state of the touch point is a touch state or a touch pending state, the touch point is reissued. Touch the touch data information corresponding to the raised state. The replacement of the touch data is realized, and the integrity of the touch data transmission is ensured.

Based on the above technical solutions, the solution is described in conjunction with a specific application scenario. Taking the combination of the infrared touch frame and the electromagnetic screen as an example, when the electromagnetic pen is written on the electromagnetic screen, the electromagnetic touch data and the infrared touch data are generated concurrently, and after the processing of the solution, if the non-priority preemption mode is used, the setting can be set. Filtering the data of the infrared touch avoids the interference of the infrared data on the electromagnetic writing, and in the writing process of the electromagnetic pen, the hand can be smoothly written on the screen, and the interference of the clothing or other people can be avoided. In the same way, adding a electromagnetic screen combination to the capacitive screen can also set the filter hand touch data to avoid the accidental touch of the hand and affect the writing of the electromagnetic pen. Optionally, in some game situations, the priority preemption mode can be turned on, and whoever writes/clicks on the touch can grab the writing sovereignty.
