Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
With the rapid development of scientific technology and the continuous improvement of living standard of people, in recent years, electronic devices using touch screens are widely used, and the electronic devices play more and more important roles in life of people and are applied to various complex scenes.
On one hand, the touch performance of the electronic equipment is required to be higher and higher by a user, and on the other hand, the touch design parameters preset when the electronic equipment leaves a factory are only matched with the preset use scene, and various other use scenes except the preset use scene cannot be perfectly matched. For example, when a mobile phone protection film is pasted on a screen of the electronic device, or when a protective sleeve is sleeved outside the electronic device, touch sensing signals collected by a touch screen of the electronic device are affected to a certain extent, so that the sensitivity of the touch screen is affected, the use experience of a user in a current use scene cannot be consistent with the use experience of the user in a terminal mode designated by the user, and the user experience is damaged.
In order to solve the above problem, embodiments of the present disclosure provide a technical solution, by acquiring a DIFF signal when a touch operation is accepted by a touch screen (i.e. a DIFF signal collected by the touch screen in a current usage scenario), wherein the DIFF signal is used to characterize the difference between the detection signal when the touch operation is accepted and the detection signal when the touch operation is not accepted by the touch screen, and adjusting the sensitivity of the touch screen according to the DIFF signal and a preset DIFF signal (namely the DIFF signal collected by the touch screen in the preset use scene), wherein the difference between the DIFF signal collected by the touch screen under the current use scene and the DIFF signal collected by the touch screen under the preset use scene can be determined according to the DIFF signal and the preset DIFF signal, according to the difference, the sensitivity of the touch screen can be further adjusted, so that the adjusted sensitivity of the touch screen is suitable for the current use scene, and the touch experience of the user using the touch screen is improved.
Embodiments of the present disclosure provide a touch screen control method applied to an electronic device equipped with a touch screen, which may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, and the like. As shown in fig. 1a, the method comprises the following steps 101 to 102:
in step 101, a DIFF signal is acquired when the touch screen accepts touch operation.
The DIFF signal is used for representing the difference between the detection signal when the touch operation is accepted and the detection signal when the touch operation is not accepted.
For example, the DIFF signal generated when the touch screen receives the touch operation may be understood as a DIFF signal acquired by the touch screen when the touch screen receives the touch operation in the current usage scenario.
Optionally, the touch screen may be a capacitive touch screen, and the detection signal may be a capacitance value. The capacitive touch screen comprises a transverse and longitudinal electrode array made of Indium Tin Oxide (ITO), and the transverse and longitudinal electrode array forms a plurality of test points which are uniformly distributed on the surface of the screen. Because self-capacitance can be generated between adjacent electrodes, the change of the self-capacitance value of each test point is collected in a self-capacitance scanning mode, and the detection of single-point touch can be realized. In addition, mutual capacitance can be generated between adjacent electrodes, so that the change of the mutual capacitance value of each test point is collected in a mutual capacitance scanning mode, and the multi-point touch detection can be realized.
Optionally, the detection signal when the touch operation is not received may be pre-stored in the electronic device where the touch screen is located, or may be acquired from another device or system. For example, the detection signal when the touch operation is not accepted may be stored in the electronic apparatus when the electronic apparatus is factory set.
Optionally, the DIFF signal when the touch screen accepts the touch operation is acquired, and the average value of the DIFF values is calculated by acquiring a plurality of DIFF values when the touch screen accepts the touch operation continuously for a plurality of times, and the average value is used as the DIFF signal. Since a finger usually touches a region when touching the touch screen, each DIFF value in the plurality of DIFF values can be understood as a DIFF value corresponding to a region. The DIFF value corresponding to a slice area may be determined by obtaining a DIFF value for each point in the area, and determining a maximum value among the DIFF values for each point in the area as the DIFF value corresponding to the slice area.
It should be noted that, before obtaining the DIFF signal when the touch screen receives the touch operation, the detection signal when the touch operation is not received may be calibrated, and through this calibration, when the external environment changes, the detection signal when the touch operation is not received may be automatically adjusted to adapt to the change of the environment, so as to prevent the false touch and the failure, and ensure the reliable and stable operation of the electronic device.
In step 102, the sensitivity of the touch screen is adjusted according to the DIFF signal and the preset DIFF signal.
For example, the preset DIFF signal may be understood as a DIFF signal acquired by the touch screen in a preset usage scene. The preset DIFF signal may be pre-stored in the electronic device where the touch screen is located, or may be obtained from other devices or systems. For example, the preset DIFF signal may be stored in the electronic device when the electronic device is factory set.
Optionally, the sensitivity of the touch screen is adjusted according to the DIFF signal and the preset DIFF signal, and the sensitivity can be adjusted according to the difference
And acquiring a signal ratio K, and adjusting the sensitivity of the touch screen according to the signal ratio K, wherein M is a DIFF signal, N is a preset DIFF signal, and the signal ratio K is inversely related to the sensitivity of the touch screen.
The sensitivity of the touch screen is adjusted according to the DIFF signal and the preset DIFF signal, and the signal difference L can be obtained according to L-M-N, and the sensitivity of the touch screen is adjusted according to L, wherein when M is larger than N, the signal difference L is in negative correlation with the sensitivity of the touch screen, and when M is smaller than N, the signal difference L is in positive correlation with the sensitivity of the touch screen.
According to the DIFF signal and the preset DIFF signal, the sensitivity of the touch screen is adjusted, and optionally, the method comprises the following steps: and acquiring a touch sensing signal adjustment value according to the DIFF signal and a preset DIFF signal, wherein the touch sensing signal adjustment value is used for being added with the sampling touch sensing signal so as to acquire a point reporting touch sensing signal for reporting points.
The point reporting refers to reporting touch information when a touch operation occurs on the touch screen, so that the electronic device makes corresponding feedback for the touch operation, and sampling the touch sensing signal is information indicating the touch operation collected by the touch screen when the touch screen receives the touch operation (which can also be understood as a detection signal when the touch screen receives the touch operation). The touch sensing signal of the touch point is used for indicating information of touch operation on the touch screen, and the electronic device can execute a touch instruction corresponding to the touch operation according to the touch sensing signal of the touch point. For example, the touch sensing signal may include a number of touches, a touch position, a touch pressure, and the like, where the touch position refers to a position where a trigger operation occurs, and the touch pressure refers to a pressure detected by the touch screen when the touch operation occurs.
For example, the report point threshold (report point threshold default) preset by the terminal is: a is 200, and the value of the preset DIFF signal is: and B is 600. Assume that the mean of the 100 frames of DIFF values (the value of the DIFF signal) continuously acquired at the current calibration is: d is 400, the touch sensing signal adjustment value F can be calculated by the following formula: f ═ a (B-D)/B ═ 200/3.
Optionally, the touch sensing signal adjustment value is added to the sampled touch sensing signal to obtain a touch sensing signal for reporting a point, and the size of the touch sensing signal for reporting a point obtained by the electronic device can be adjusted, so that the sensitivity of the touch screen is adjusted. For example, when the electronic device executes a corresponding operation according to the touch sensing signal, the electronic device may execute a touch instruction corresponding to the touch operation only when the touch sensing signal is greater than a certain threshold, and therefore, when the touch sensing signal adjustment value is a positive value, the absolute value of the touch sensing signal adjustment value is larger, and the sensitivity of the touch screen is higher. When the touch sensing signal adjustment value is a negative value, the larger the absolute value of the touch sensing signal adjustment value is, the lower the sensitivity of the touch screen is.
Optionally, the sensitivity of the touch screen is adjusted according to the DIFF signal and the preset DIFF signal, or a touch sensing signal reporting threshold is obtained according to the DIFF signal and the preset DIFF signal, and the touch sensing signal reporting threshold is used for screening the sampled touch sensing signals, so that a signal with a signal value greater than or equal to the touch sensing signal reporting threshold is determined in the sampled touch sensing signals as a reporting touch sensing signal for reporting points. It should be noted that, the touch sensing signal reporting threshold is obtained according to the DIFF signal and the preset DIFF signal, the touch sensing signal reporting threshold may be directly generated according to the DIFF signal and the preset DIFF signal, or the preset touch sensing signal reporting threshold may be adjusted according to the DIFF signal and the preset DIFF signal, so as to obtain the touch sensing signal reporting threshold.
The electronic device may record the number of point reporting times for one time when a signal value of a certain sampled touch sensing signal in the plurality of sampled touch sensing signals is greater than or equal to a touch sensing signal point reporting threshold, determine a touch operation corresponding to the sampled touch sensing signal, and control the electronic device to execute a touch instruction corresponding to the touch operation. As the smaller the touch sensing signal hit threshold is, the smaller the touch operation capable of triggering the touch instruction is, for example, a smaller pressing pressure is applied to the touch screen, so that the response of the electronic device to the touch operation can be awakened. The smaller the touch sensing signal reporting threshold value is, the higher the sensitivity of the touch screen is, and on the contrary, the larger the touch sensing signal reporting threshold value is, the lower the sensitivity of the touch screen is.
For example, the report point threshold (report point threshold default) preset by the terminal is: a is 200, and the value of the preset DIFF signal is: b is 600, and the trigger adjustment threshold is: and C is 50. Assume that the mean of the 100 frames of DIFF values (the value of the DIFF signal) continuously acquired at the current calibration is: if D is 400, the adjusted preset touch sensing signal reporting threshold E may be calculated by the following formula: and if the absolute value of the (B-D) is larger than C, the adjusted preset touch sensing signal hit threshold value E is equal to a (1- (B-D)/B) 400/3.
The embodiment of the disclosure provides a technical solution, in which a DIFF signal (i.e., a DIFF signal collected by a touch screen in a current usage scenario) when the touch screen accepts a touch operation is obtained, where the DIFF signal is used to represent a difference between a detection signal when the touch screen accepts the touch operation and a detection signal when the touch screen does not accept the touch operation, a sensitivity of the touch screen is adjusted according to the DIFF signal and a preset DIFF signal (i.e., a DIFF signal collected by the touch screen in the preset usage scenario), where a difference between the DIFF signal collected by the touch screen in the current usage scenario and the DIFF signal collected by the touch screen in the preset usage scenario can be determined according to the DIFF signal and the preset DIFF signal, and according to the difference, the sensitivity of the touch screen can be further adjusted to adapt to the current usage scenario, so as to ensure that a feeling of a user using the touch screen in the current usage scenario is consistent with a feeling of the user using the touch screen in the preset usage scenario, thereby improving the user experience.
In one embodiment, as shown in fig. 1b, in step 101, acquiring a DIFF signal when the touch screen receives a touch operation, may be implemented by step 1011:
in step 1011, when the touch screen continuously receives touch operations for multiple times, a DIFF signal corresponding to each touch operation is acquired.
Before step 102, the method further comprises step 103:
in step 103, the fluctuation condition of the DIFF signal corresponding to the continuous multi-touch operation is calculated, and the fluctuation condition is determined to meet the preset fluctuation condition.
Illustratively, calculating the fluctuation condition of the DIFF signal corresponding to the continuous multiple touch operations, and determining that the fluctuation condition satisfies the preset fluctuation condition, may be implemented by: determining the DIFF signal peak value of the DIFF signal in the touched area corresponding to each touch operation according to the DIFF signal corresponding to each touch operation, acquiring the mean square error of the DIFF signal peak values corresponding to continuous multiple touch operations and/or the average value of the DIFF signal peak values corresponding to continuous multiple touch operations, and determining that the fluctuation condition meets the preset fluctuation condition when the mean square error and/or the average value meets the threshold condition.
Wherein, the average value of the DIFF signal peak values corresponding to the continuous multiple touch operations can reflect the fluctuation amplitude of the DIFF signal corresponding to the continuous multiple touch operations, the mean square error of the DIFF signal peak values corresponding to the continuous multiple touch operations can reflect the discrete degree of the fluctuation amplitude of the DIFF signal corresponding to the continuous multiple touch operations, when the mean square error and/or the average value satisfy the threshold condition (for example, the mean square error belongs to the preset mean square error value interval, and the average value belongs to the preset average value interval), it can be considered that the fluctuation condition of the DIFF signal corresponding to the multiple touch operations is normal, the DIFF signal corresponding to the multi-touch operation is disturbed, or has a smaller probability of generating an error, therefore, the sensitivity of the touch screen can be further adjusted according to the collected DIFF signals and the preset DIFF signals, so that the accuracy of sensitivity adjustment is improved, and the user experience is improved.
