Description

Touch signal response method and device and storage medium

Technical Field

The present disclosure relates to the field of touch technologies, and in particular, to a touch signal response method, device and storage medium.

Background

In the prior art, a terminal is usually configured with a capacitive display screen, when a user finger approaches or touches the display screen, due to the action of an electric field of a human body, the user finger and the display screen form a coupling capacitor, so that a capacitance value of the display screen changes, and at this time, the terminal detects a touch signal on the display screen and determines whether to respond to the touch signal according to a capacitance difference value of the touch signal and a preset response threshold value.

Namely, when the capacitance difference value of the touch signal is greater than the response threshold value, the terminal responds to the touch signal, and therefore the user can control the display screen. And when the capacitance difference value of the touch signal is not greater than the response threshold value, the terminal ignores the touch signal.

If the terminal sets a large response threshold value, when the user wears the gloves to control the display screen, the capacitance difference value of the generated touch signal is small, the terminal may not respond to the touch signal, and the operation is inconvenient. If the terminal sets a smaller response threshold, when the user's finger does not touch the display screen but hovers above the display screen, a touch signal with a capacitance difference larger than the response threshold may be generated, which causes the terminal to respond to the touch signal, resulting in a malfunction. Therefore, it is desirable to provide a touch signal response method, which can avoid the misoperation and ensure that the user can still conveniently control the display screen while wearing gloves.

In the method provided by the embodiment of the disclosure, the Hover suppression function is used for indicating to respond according to a first response threshold, when the Hover suppression function is started, the touch signal on the display screen is detected, when it is determined that the capacitance difference value of the touch signal is not greater than the first response threshold and a movement event occurs after the touch signal continues for at least a first preset time period in the same screen area, it is determined that the user is operating the terminal while wearing gloves at the time, so that the Hover suppression function is turned off, and a response is performed according to a second response threshold, which is smaller than the first response threshold. The embodiment of the disclosure fully considers the operation habits of the user, that is, the fingers of the user generally pause for a period of time and then perform sliding operation when controlling the display screen, and the fingers of the user do not pause for a period of time and then perform sliding operation when hovering above the terminal, so that the condition that the user wears gloves and the condition that the fingers of the user hovers above the terminal are distinguished by detecting the touch signal generated by pausing for a period of time and then performing sliding operation, thereby avoiding misoperation and ensuring that the user can still conveniently control the display screen when wearing the gloves.

In one possible implementation, detecting a touch signal on a display screen includes:

In one possible implementation manner, the first preset time length is a product of a preset unit time length and a preset number of times, and the preset unit time length is a time length required for traversing all screen areas in the display screen in one detection period;

and when the capacitance difference value of the touch signal is determined to be not greater than the first response threshold value, a movement event occurs after at least a first preset time duration in the same screen area, and the number of the screen areas acted by the touch signal is not less than a preset number, closing the Hover suppression function.

Fig. 2 is a flowchart illustrating a touch signal response method according to an exemplary embodiment, which is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

in step 201, the Hover suppression function is turned on.

The terminal can be a mobile phone, a tablet computer and other devices. The terminal is configured with a capacitive Display screen, and the Display screen may adopt a TDDI (Touch and Display Driver Integration) in-cell (an embedded Touch panel), an Oncell (an embedded Touch panel), a Hybrid in-cell (another embedded Touch panel), a GFF (Glass-Film, an external-hanging Touch panel), a GG (Glass-Glass, another external-hanging Touch panel), and the like.

The terminal is preset with a reference capacitance value, and the reference capacitance value is the capacitance value of the display screen when no finger of a user is close to or touches the display screen. When a user finger is close to or touches the display screen, due to the action of a human body electric field, the user finger and the display screen form a coupling capacitor, so that the capacitance value of the display screen changes, at the moment, the terminal can obtain the difference between the larger capacitance value and the smaller capacitance value between the capacitance value of the display screen and the reference capacitance value to obtain a capacitance difference value, and at the moment, the terminal detects a touch signal on the display screen. Wherein the smaller the distance between the user's finger and the display screen, the larger the capacitance difference is generated.

The terminal may obtain the capacitance difference value through the detection node, or the terminal may obtain the capacitance difference value in other manners.

In one possible implementation manner, the terminal includes a detection node, a display screen, and a control unit, the detection node is disposed on the display screen, and the detection node is connected to the control unit. The detection node can obtain the current capacitance value of the display screen and send the capacitance value to the control unit, and the control unit obtains the difference between the larger capacitance value and the smaller capacitance value of the capacitance value and the reference capacitance value after receiving the capacitance value, so as to obtain the capacitance difference value.

In the embodiment of the present disclosure, the terminal provides a Hover suppression function, where the Hover suppression function is configured to instruct to respond according to a first response threshold, and according to whether the Hover suppression function is turned on or not, the terminal may include the following operation modes:

firstly, opening a Hover inhibition function:

and when the terminal detects that the capacitance difference value of the touch signal is greater than the first response threshold value, responding to the touch signal, thereby realizing the control of the user on the display screen. And when the capacitance difference value of the touch signal is not larger than the first response threshold value, neglecting the touch signal.

Wherein the first response threshold may be determined according to a minimum value of a capacitance difference generated when the user controls the display screen without wearing gloves.

Second, closing Hover inhibition function:

and when the terminal detects that the capacitance difference value of the touch signal is greater than the second response threshold value, responding to the touch signal, thereby realizing the control of the user on the display screen. And when the capacitance difference value of the touch signal is not larger than the second response threshold value, neglecting the touch signal.

The second response threshold value can be determined according to the minimum value of the capacitance difference value generated when the display screen is controlled under the condition that the user wears gloves, and the second response threshold value is smaller than the first response threshold value.

The difference between the two operation modes is that the adopted response thresholds are different, when the capacitance difference value of the touch signal is greater than the second response threshold and smaller than the first response threshold, the terminal responds to the touch signal under the condition that the Hover suppression function is turned off, and the terminal does not respond to the touch signal under the condition that the Hover suppression function is turned on.

Regarding the manner of responding to the touch signal, the terminal may obtain the display interface of the current display screen in advance, obtain the position of the touch signal when the touch signal is detected, and respond to the touch signal based on the display interface of the current display screen and the position of the touch signal. The position of the touch signal may be represented by coordinates of the touch signal in a coordinate system, and the coordinate system may be a coordinate system established by using the upper left corner or the upper right corner of the display screen and the like as an origin.

For example: when a user wants to start the application client A, the user touches the position of the application icon of the application client A in the display screen with a finger to generate a touch signal. When the terminal detects a touch signal, the position of the touch signal is obtained, the position of the touch signal is determined to be the position of an application icon of the application client A, the application client A is started, and the interface of the application client A is displayed.

In the embodiment of the disclosure, taking the condition of turning on the Hover suppression function as an example, the terminal may automatically turn on the Hover suppression function when the terminal is turned on, or the terminal provides a switch of the Hover suppression function, and a user may control turning on or off of the Hover suppression function through the switch, and then when the user turns on the switch, the terminal turns on the Hover suppression function, or the terminal may also turn on the Hover suppression function in other manners.

In step 202, each screen area in the display screen is traversed according to the distribution positions of the plurality of screen areas in the display screen, and the touch signal on the traversed screen area is detected.

In the embodiment of the disclosure, the display screen of the terminal includes a plurality of screen areas, and the screen areas are respectively distributed at different positions of the display screen. The terminal traverses each screen area in the display screen, acquires the capacitance difference value of the screen area when traversing to one screen area each time, and determines whether a touch signal is detected on the screen area according to the capacitance difference value.

Regarding the division manner of the multiple screen areas, in a possible implementation manner, multiple detection nodes are configured on the display screen, and the screen area where each detection node is located can be regarded as one screen area. For example: the detection nodes include 18 rows and 32 columns, and the number of the detection nodes is 18 × 32 — 576, and accordingly, the display screen of the terminal includes 576 screen regions.

Regarding the mode of traversing each screen region, the terminal may sequentially acquire the screen regions from left to right and from top to bottom according to the distribution positions of the screen regions, or sequentially acquire the screen regions from top to bottom and from left to right, or may also adopt other modes.

In a possible implementation manner, the terminal sets a preset threshold, and after the obtained capacitance difference value of each screen area, determines whether the screen area detects a touch signal according to the obtained capacitance difference value and the preset threshold. The method comprises the steps that after a terminal obtains a capacitance difference value, the obtained capacitance difference value is compared with a preset threshold value, when the capacitance difference value is larger than the preset threshold value, the terminal determines that a screen area corresponding to the capacitance difference value detects a touch signal, and when the capacitance difference value is not larger than the preset threshold value, the terminal determines that the screen area corresponding to the capacitance difference value does not detect the touch signal. The preset threshold value can be determined according to the minimum value of the capacitance difference value generated when a user controls the display screen under various conditions.

For example: as shown in fig. 3, when the preset threshold is 15 farads, the screen area with the capacitance difference larger than 15 farads is used as the screen area where the touch signal is detected.

By comparing the acquired capacitance difference value with a preset threshold value, the problem that the capacitance difference value of a screen area is changed due to dust in the air or other factors to cause misjudgment of the terminal is solved, and the accuracy of detecting a touch signal by the terminal is improved.

It should be noted that, the step 202 is only described in a manner that the terminal detects the touch signal by traversing the plurality of screen areas, and in another embodiment, the terminal may detect the touch signal on the display screen in other manners.

It should be noted that, in the embodiment of the present disclosure, the step 202 is executed after the step 201 as an example, but in another embodiment, the step 202 may be executed at any time after the terminal turns on the Hover suppression function, and the step 202 may be executed one or more times, and only needs to be executed each time when the terminal turns on the Hover suppression function.

In step 203, the number of continuous touch times of each screen area is counted, where the number of continuous touch times of a screen area is the number of detection cycles of continuously detecting the same touch signal with the capacitance difference not greater than the first response threshold on the screen area, that is, the number of continuous touch times of the screen area is n if the same touch signal with the capacitance difference not greater than the first response threshold is detected on the same screen area in n consecutive detection cycles.

In the embodiment of the disclosure, in the process of controlling the display screen by the finger of the user, the touch signal is triggered on the display screen, and at this time, the terminal may receive a touch notification, where the touch notification includes a touch identifier, a touch area, and a touch event. The touch control identification corresponds to the touch control signal one to one, when the terminal detects the touch control signal for the first time, the touch control identification is configured for the touch control signal, and in the process that the touch control signal slides on the display screen, the touch control identification of the touch control signal is unchanged. The touch area is an action area of the touch signal on the display screen, the touch area can be represented by coordinates in the display screen, and for the same touch signal, the touch area changes correspondingly in the sliding process of the touch signal on the display screen. The touch event is an event of a touch signal, the touch event may include a click event, a movement event, and the like, the touch event may be represented by an event identifier, and different event identifiers represent different types of touch events.

For example, the touch identifier may be represented by a touch ID (identity), the touch event is represented by Status, and the touch notification received by the terminal is shown in table 1.

TABLE 1

Touch control identification	Moving events
		ID	Status＝2

Regarding the way the touch identifiers are represented by touch ID, in one possible implementation, the touch identifier of the finger controlling the first display screen can be represented by ID0, the touch identifier of the finger controlling the second display screen can be represented by ID1, and so on, or the touch identifiers can be represented by other ways.

In a possible implementation manner, the terminal may receive the touch notification reported by the display screen by calling an interface of the display screen, or the terminal may also receive the touch notification in another manner.

In the embodiment of the disclosure, after traversing each screen region of the display screen and acquiring the capacitance difference value of each screen region, the terminal continues to repeat the step to acquire the capacitance difference value of each screen region again, thereby realizing alternate detection of each screen region. Traversing all the screen areas in the display screen once can be called a detection period, and in each detection period, the capacitance difference value of each screen area is obtained to detect the touch signal on each screen area.

In the detection process, the continuous touch frequency of each screen area is counted. The number of continuous touch times of the screen area is the number of times that the same touch signal with the capacitance difference value not greater than the first response threshold value is detected in a plurality of continuous detection periods, that is, the number of detection periods that the same touch signal with the capacitance difference value not greater than the first response threshold value is continuously detected in the screen area.

When counting the continuous touch frequency of each screen area, the terminal detects that the capacitance difference value of the screen area is not larger than a first response threshold value in each detection period, obtains the touch identifier of the touch signal, and adds one to the continuous touch frequency when determining that the touch identifier is the same as the touch identifier obtained on the screen area in the last detection period, namely that the touch signal is the same as the previous touch signal. In the counting process, once the touch identification of the touch signal is detected to change once in the middle, or the capacitance difference value of the touch signal is greater than a first preset threshold value, the counted continuous touch times are cleared, and counting is performed again.

In step 204, when it is detected that the touch signal has a movement event on any screen area and the number of consecutive touches corresponding to the touch signal is not less than the preset number, the Hover suppression function is turned off, and a response is performed according to a second response threshold, where the second response threshold is less than the first response threshold.

Considering that when the user controls the display screen, the finger of the user generally stops for a period of time and then performs the sliding operation. Therefore, in order to determine that the finger of the user stops for a period of time, the terminal further sets a preset number of times, and when the number of times of continuous touch counted by the terminal is not less than the preset number of times, it indicates that the finger of the user stops for a period of time. The preset number of times may be determined according to a time for which the user's finger is stopped in a general case.

The movement event refers to that the touch positions of the same touch signal detected by the terminal twice continuously are different, and when the terminal detects that the touch signal has the movement event in any screen area and the continuous touch frequency corresponding to the touch signal is not less than the preset frequency, the movement event indicates that the user controls the display screen while wearing gloves.

In a possible implementation manner, the terminal acquires the touch identifier and the touch position of the touch signal when traversing each screen area in the display screen and detecting the touch signal, and also acquires the touch identifier and the touch position of the touch signal when traversing each screen area of the display screen next time and detecting the touch signal again, where the touch signals with the same touch identifier are the same touch signal, and if the touch identifiers of two times are the same, the terminal determines whether the touch signal has moved based on the touch positions acquired twice.

For example: when the terminal periodically obtains the capacitance difference value of each screen area to detect the touch signal on each screen area, in a detection period, when the terminal detects the touch signal, the terminal obtains the touch identifier of the touch signal as ID1 and the touch position as (x, y), when in the next detection period, the terminal traverses each area of the display screen again and detects the touch signal again, the terminal obtains the touch identifier of the touch signal detected again as ID1 and the touch position as (m, n), and the touch position changes, then the terminal determines that the touch signal is detected to generate a movement event.

The terminal closes the Hover suppression function when determining that the user controls the display screen under the condition of wearing gloves, and responds according to the second response threshold, and because the second response threshold is smaller than the first response threshold, and the capacitance difference of the generated touch signal is larger than the second response threshold when the user controls the display screen under the condition of wearing gloves, the terminal can respond to the touch signal, and the sensitivity of the display screen is increased.

It should be noted that, in the above-mentioned steps 203-204, it is only described how the terminal determines that the user controls the terminal while wearing the glove when the number of continuous touches corresponding to the touch signal is not less than the preset number. The time length required for traversing all screen areas in the display screen is called preset unit time length, the product of the preset unit time length and the preset times is first preset time length, and through the statistical mode, when the continuous touch times of the screen areas reach the preset times, the duration time length of the touch signals acting in the screen areas reaches the first preset time length.

In another embodiment, it may also be determined in other manners whether the user controls the display screen while wearing gloves, and it is only necessary to ensure that the Hover suppression function is turned off when the terminal determines that the capacitance difference of the touch signal is not greater than the first response threshold and a movement event occurs after the touch signal continues for at least a first preset time period in the same screen area.

In one possible implementation manner, when it is determined that the capacitance difference of the touch signal is not greater than the first response threshold, a movement event occurs after the same screen area lasts for at least a first preset time period, and the number of the screen areas acted by the touch signal is not less than a preset number, the Hover suppression function is turned off.

The number of the screen areas acted by the touch signal refers to the total number of the adjacent screen areas, the preset number can be determined according to the number of the screen areas included in the contact area between the finger of the user and the display screen when the finger touches the display screen under normal conditions, and the preset number can be 7 or 9, or can also be other numerical values meeting the conditions.

When the terminal traverses each screen area in the display screen, the terminal may detect a touch signal generated by dust or other factors, and respond to the touch signal when detecting that a movement event occurs in the touch signal in the next detection period, thereby causing misoperation. The screen area acted by the touch signal generated by the dust or other factors is usually smaller than the preset number, so that the method provided by the embodiment of the disclosure can ignore the touch signal generated by the dust or other factors by setting the preset number, ensure that the touch signal is generated by the touch operation of the user finger on the display screen, and avoid generating misoperation.

In another possible implementation manner, when it is determined that the capacitance difference of the touch signal is not greater than the first response threshold, a movement event occurs after the touch signal is continuously moved in the same screen area for at least a first preset time period, and the movement distance of the touch signal is not less than a preset distance, the Hover suppression function is turned off.

In the embodiment of the disclosure, the terminal may obtain the moving distance of the touch signal, and compare the moving distance with the preset distance, when the moving distance does not reach the preset distance, it is determined that no moving event occurs, and when the moving distance reaches the preset distance, it is determined that the moving event occurs, thereby avoiding a situation that the terminal responds to the touch signal due to the fact that the touch signal moves for a certain distance because of the sliding of the user's hand.

The moving distance of the touch signal is not less than the preset distance and comprises at least one of the following items: the moving distance of the touch signal in the transverse direction is not less than a first preset distance; the moving distance of the touch signal in the longitudinal direction is not less than a second preset distance.

It should be noted that the terminal configures the display screen, and may also run a firmware program of the display screen, and the touch signal response method is executed by the firmware program, where the firmware program may be a firmware program, or may also be another program.

Fig. 4 is a schematic diagram illustrating an operational flow according to an exemplary embodiment, as shown in fig. 4, the operational flow including:

the method comprises the steps that under the condition that the Hover suppression function is started, the terminal firstly detects whether a touch signal exists in a screen area, if yes, the terminal detects whether the touch signal continues to exist in the same screen area for at least a first preset time length and then generates a mobile event, if the conditions are met, the Hover suppression function is closed, and if the conditions are not met, the terminal continues to start the Hover suppression function.
