Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
As a latest input device, the touch screen provides a simple, convenient and natural man-machine interaction mode for the terminal, gives a brand-new appearance to multimedia, and is a brand-new multimedia interaction device with great attraction.
As an important device and a man-machine interaction inlet in a terminal, the touch screen is mainly a device for realizing a capacitive touch screen technology based on a capacitance induction principle. The capacitive touch screen technology works by using current induction of a human body.
Generally, a capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are respectively coated with an Indium Tin Oxide (ITO), the outermost layer is a thin silica glass protective layer, the interlayer ITO coating serves as a working surface, four electrodes are led out from four corners, and the inner ITO serves as a shielding layer to ensure a good working environment. When a finger touches the metal layer, the finger and the surface of the touch screen form a coupling capacitor due to an electric field of a human body, and the capacitor is a direct conductor for high-frequency current, so that the finger sucks very small current from a contact point. The currents respectively flow out of the electrodes on the four corners of the touch screen, the currents flowing through the four electrodes are in proportion to the distance from the finger to the four corners, and the controller obtains the position of the touch point through accurate calculation of the four current proportions.
In use, the capacitive touch screen may be interfered by a strong light signal, for example, a fluorescent lamp or the like may exist in various scenes of manufacturing, selling and using the capacitive touch screen, and the terminal may be interfered by the strong light signal when being touched under the strong light. In the presence of interference, the touch information fed back by the capacitive touch screen may be distorted, creating a false alarm point condition, thereby affecting its accuracy and reliability.
In order to overcome the above defect, in the embodiment of the present application, the terminal may detect the illumination brightness corresponding to the current environment, and then set the report point threshold adapted to the current illumination brightness by using the preset illumination threshold, so that when the report point is processed by using the report point threshold, the occurrence of false report points is effectively reduced. That is to say, when illumination intensity is great, the terminal can be adaptability's improvement report threshold value, and then can overcome the interference of light signal to the touch-sensitive screen, has avoided the production of wrong report point, has improved the accuracy and the reliability of touch-sensitive screen, promotes the intelligence at terminal.
Specifically, in the embodiment of the application, the terminal determines whether the current illumination intensity reaches the preset illumination threshold, and if the current illumination intensity is greater than or equal to the preset illumination threshold, the terminal may set a higher report point threshold, so that the threshold for triggering report points is improved along with the improvement of the current illumination intensity, and therefore the problem of false report points of the touch screen caused by the interference of strong light signals is solved.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a touch screen point reporting method, where the touch screen point reporting method is applied in a terminal, and fig. 1 is a schematic view of an implementation flow of the touch screen point reporting method, as shown in fig. 1, in an embodiment of the present application, a method for a terminal to evaluate an image registration algorithm may include the following steps:
In the embodiment of the application, when the terminal detects the touch operation, the current illumination intensity and the current touch parameter corresponding to the touch parameter can be acquired and obtained first. The current illumination intensity is used for representing the light intensity in the environment where the terminal is located, and the current touch parameter is used for representing the specific information of the touch operation received by the terminal.
It should be noted that, in the embodiments of the present application, the terminal may be any device having communication and storage functions, for example: tablet computers, mobile phones, electronic readers, remote controllers, personal Computers (PCs), notebook computers, vehicle-mounted devices, network televisions, wearable devices, and the like.
It is understood that in the embodiment of the present application, the terminal may be configured with a touch screen, so that the current touch parameter may be detected using the touch screen. For example, the terminal may be configured with a capacitive touch screen, and when a finger touches the touch screen of the terminal to generate a touch operation, the terminal may detect a current corresponding to the touch operation through the capacitive touch screen, so as to determine a corresponding touch parameter.
Further, in the embodiment of the present application, the terminal may be further configured with a light sensor, so that the current illumination intensity may be detected by the light sensor.
Specifically, a photosensor is a sensor that converts an optical signal into an electrical signal using a photosensor, and its sensitive wavelength is in the vicinity of visible wavelengths, including infrared wavelengths and ultraviolet wavelengths. The optical sensor is not limited to detecting light, and can be used as a detecting element to form other sensors to detect a plurality of non-electric quantities, as long as the non-electric quantities are converted into changes of optical signals. The optical sensor mainly comprises a photosensitive element, and the photosensitive element is developed rapidly, has various varieties and is widely applied at present, such as a photosensitive resistor, a photosensitive diode, a phototriode, a silicon photocell and the like sold in the market. The light sensor can sense the ambient light condition and feed back the terminal, so that the terminal can automatically adjust the backlight brightness, and the power consumption of the product is reduced. For example, in the application of handheld devices such as mobile phones and notebook mobile devices, the power consumed by the display is up to 30% of the total power of the battery, and the working time of the battery can be prolonged to the maximum extent by adopting the ambient light sensor. On the other hand, the light sensor helps the terminal to provide a soft picture. When the ambient brightness is high, the terminal equipped with the light sensor can automatically adjust to high brightness. When the external environment is dark, the terminal can also be adjusted to low brightness.
It should be noted that, in the embodiment of the present application, when the terminal acquires the current illumination intensity, the terminal may detect the ambient illumination after detecting the touch operation, so as to acquire the current illumination intensity; or, the light sensor may be used to perform real-time detection to obtain the real-time illumination intensity, and then the current real-time illumination intensity is used as the current illumination intensity after the touch operation is detected. Here, no specific limitation is imposed.
It can be understood that, in the embodiment of the present application, a touch screen configured in a terminal may perform detection of touch operation, and then transmit a correspondingly generated coupling capacitance to a processing system in the terminal, so that the terminal may obtain a corresponding touch parameter; on the other hand, the touch screen may also determine the touch parameter corresponding to the touch operation directly based on the coupling capacitance generated by the touch operation.
That is to say, in the embodiment of the application, when the terminal acquires the touch parameter corresponding to the touch operation, the terminal may receive the coupling capacitance acquired by the touch screen, and then determine the touch parameter corresponding to the touch operation based on the coupling capacitance; or directly receiving touch screen calculation and then determining touch parameters corresponding to touch operation based on the coupling flashlight. Here, no specific limitation is applied.
Further, in the embodiment of the present application, the current illumination intensity may be an illumination intensity in a current environment where the terminal is located. Wherein, the illumination intensity is a physical term used to indicate the intensity of illumination and the amount of illumination of the surface area of the object, and refers to the luminous flux of the received visible light per unit area. Abbreviated as illuminance, in Lux or lx.
It is understood that, in the embodiment of the present application, the current touch parameter may include a touch position and a touch point value corresponding to the touch operation. Specifically, in the present application, the touch position may be a coordinate point on the touch screen or a continuous line on the touch screen. That is, corresponding to a click operation or a press operation, the touch position is a click point or a press point on the touch screen; corresponding to the sliding operation, the touch position is a continuous straight line or a curve on the touch screen.
Further, in the embodiment of the present application, the reward point value is determined based on the capacitance data corresponding to the touch operation. Specifically, after a touch operation is received by a touch screen in the terminal, real-time capacitance data generated by the touch operation is detected and obtained, then difference calculation can be performed on the reference capacitance data and the real-time capacitance data to obtain difference data, and after capacitance standard conversion is performed on the difference data, a reporting value corresponding to the touch operation can be obtained.
102, setting a report point threshold value based on the current illumination intensity and a preset illumination threshold value; the preset illumination threshold is used for overcoming the interference of the optical signal to the touch screen.
In the embodiment of the application, when the touch operation is detected, after the current illumination intensity and the current touch parameter corresponding to the touch operation are obtained, the terminal can set the report point threshold by using the current illumination intensity and the preset illumination threshold.
It should be noted that, in the embodiment of the present application, the preset illumination threshold is used to determine the magnitude of the current illumination intensity, so that a reporting point threshold adapted to the current illumination intensity may be further set based on the current illumination intensity. Further, in the embodiment of the present application, the preset illumination threshold may overcome interference of a strong light signal to the touch screen.
It can be understood that, in the embodiment of the present application, the preset illumination threshold is a determined numerical value representing the illumination intensity, and the terminal may set the preset illumination threshold in advance. Illustratively, the terminal may set the preset illumination threshold to 100LUX.
Further, in the embodiment of the present application, when the terminal sets the report point threshold by using the preset illumination threshold, the report point threshold adapted to the current illumination intensity may be determined in multiple ways.
For example, in the present application, when determining the report point threshold, the terminal may compare the current illumination intensity with a preset illumination threshold to obtain a comparison result, and then set the report point threshold by using the comparison result. Specifically, if the comparison result is that the current illumination intensity is greater than or equal to the preset illumination threshold, the terminal may set the first threshold as the report point threshold; if the comparison result is that the current illumination intensity is smaller than the preset illumination threshold, the terminal may set the second threshold as the report point threshold.
It is understood that in the embodiment of the present application, the greater the illumination intensity in the current environment in which the terminal is located, the greater the interference caused to the touch screen may be. That is, the higher the current illumination intensity is, the larger the corresponding set hit threshold value is. Thus, in the application, the second threshold may be smaller than the first threshold.
For example, in the present application, when the terminal determines the report point threshold, a ratio between the current illumination intensity and a preset illumination threshold may be calculated first, and then the report point threshold is determined by using the ratio and a reference report point. Specifically, the terminal may perform mathematical operation on a ratio between the current illumination intensity and the preset illumination threshold value and the reference report point, so as to calculate and obtain the report point threshold value.
Further, in the embodiment of the present application, when the terminal determines the report point threshold, the terminal may also pre-store the current illumination intensity input value in the calculation model, so as to obtain the report point threshold corresponding to the current illumination intensity.
That is to say, in the present application, the value of the report point threshold is determined based on the current illumination brightness, so that the terminal can perform report point processing based on the report point threshold to reduce the interference of the current illumination brightness as much as possible.
And 103, performing point reporting processing according to the current touch parameter and the point reporting threshold value.
In the embodiment of the application, after the terminal sets the report point threshold based on the current illumination intensity and the preset illumination threshold, the touch operation can be subjected to report point processing by using the current touch parameter and the report point threshold.
It should be noted that, in the embodiment of the present application, the reporting threshold is used to determine whether to perform reporting processing on the touch parameter corresponding to the touch operation. Specifically, each time a touch operation occurs, the terminal may obtain a capacitance difference value based on capacitance data generated by the touch operation and reference capacitance data, and then may determine whether to perform reporting processing by comparing a reporting threshold value with the capacitance difference value.
Further, in the embodiment of the present application, when the terminal compares the reporting threshold with the capacitance difference, the terminal may first perform capacitance standard switching on the capacitance difference to obtain a reporting value, and then compare the reporting threshold with the reporting value.
It can be understood that, in the embodiment of the present application, when performing report processing according to the current touch parameter and the report threshold, the terminal may compare the report value in the touch parameter with the report threshold to obtain a comparison result, so as to determine whether to perform report processing according to the comparison result.
Specifically, in the embodiment of the present application, after the terminal obtains the comparison result between the report value and the report threshold, if the comparison result is that the report value is greater than or equal to the report threshold, it may be considered that the touch operation is not an erroneous operation, and the terminal may perform reporting processing on the touch position; correspondingly, if the comparison result is that the report value is smaller than the report threshold, the touch operation can be regarded as the misoperation, and the terminal selects not to perform report processing.
It should be noted that, in the embodiment of the present application, the current touch parameter acquired by the terminal may further include specific information of the touch object, where the touch object may be a finger of a user, and accordingly, the specific information of the touch object may be fingerprint information, a touch area, and the like.
Further, in the embodiment of the present application, after the terminal obtains the comparison result between the report point value and the report point threshold, if the comparison result is that the report point value is greater than or equal to the report point threshold, it may be determined that the touch operation is not a false operation, and the terminal may also report the fingerprint information and the touch area at the same time.
It can be understood that, in the embodiment of the present application, the report threshold is determined by the terminal based on the current illumination intensity and the preset illumination threshold, and therefore, in the process of determining whether to report the touch operation by using the report threshold, the terminal can consider the interference factor of the current illumination intensity, so that the interference of the optical signal to the touch screen can be effectively avoided.
According to the touch screen point reporting method provided by the embodiment of the application, when touch operation is detected, a terminal acquires current illumination intensity and current touch parameters corresponding to the touch operation; setting a report point threshold value based on the current illumination intensity and a preset illumination threshold value; the preset illumination threshold is used for overcoming the interference of an optical signal on the touch screen; and performing point reporting processing according to the current touch parameter and the point reporting threshold value. Therefore, in the application, the terminal can detect the illumination brightness corresponding to the current environment, and then the preset illumination threshold value is used for setting the point reporting threshold value adaptive to the current illumination brightness, so that when the point reporting threshold value is used for point reporting processing, the occurrence of mistaken point reporting is effectively reduced. That is to say, when illumination intensity is great, the terminal can the improvement report threshold value of adaptability, and then can overcome the interference of light signal to the touch-sensitive screen, has avoided the production of wrong report point, has improved the accuracy and the reliability of touch-sensitive screen, promotes the intelligence at terminal.
Based on the foregoing embodiment, in another embodiment of the present application, fig. 2 is a first structural diagram of a method for reporting a touch screen, and as shown in fig. 2, a touch screen, an optical sensor, and a processing system may be disposed in a terminal.
It is understood that, in the embodiment of the present application, the touch screen may be an Integrated Circuit (IC) configured in the terminal for performing the receiving of the touch operation.
It should be noted that, in the embodiment of the present application, the light sensor may perform detection of the current illumination intensity. Specifically, when detecting the current illumination intensity, the light sensor may start to detect the illumination intensity of the current environment where the terminal is located after the touch screen receives the touch operation; or detecting in real time to obtain real-time illumination intensity, and then taking the current real-time illumination intensity as the current illumination intensity after receiving the touch operation; the illumination intensity can also be detected according to a preset period to obtain a plurality of continuous illumination intensities, and then the current illumination intensity is determined based on the plurality of continuous illumination intensities.
For example, in the embodiment of the present application, the terminal may preset a preset period for the light sensor to detect the illumination intensity, for example, the preset period may be 500ms or 200ms.
Further, in the embodiment of the present application, data interaction between the touch screen and the processing system is possible. Specifically, data transmission between the touch screen and the processing system may be performed through interfaces such as a data report Interface (INT), a Serial Peripheral Interface (SPI), or an I2S (Inter-IC Sound Bus). The SPI interface operates in a master-slave mode, which generally has a master device and one or more slave devices, and includes the following four signals: (1) MOSI-master data out, (2) MISO-master data in, (3) SCLK-clock signal, generated by master (4)/SS-slave enable signal, controlled by master. I2S is a bus standard established for audio data transmission between digital audio devices, I2S has 3 main signals: 1. the serial clock SCLK, also called a bit clock, corresponds to each bit of data of the digital audio, and SCLK has 1 pulse. 2. And a frame clock LRCK for switching data of the left and right channels. An LRCK of "1" indicates that data of the left channel is being transferred, and a value of "0" indicates that data of the right channel is being transferred. 3. Serial data SDATA is audio data represented by two's complement. Sometimes, in order to make the synchronization between the systems better, it is necessary to transmit a signal MCLK, which is called a master Clock, also called a system Clock (Sys Clock).
Further, in the embodiment of the application, when the touch screen receives a touch operation, the coupling capacitance corresponding to the touch operation may be detected and obtained, so as to obtain capacitance data.
It is understood that in the embodiment of the present application, after the touch screen detects and obtains the capacitance data, the touch screen may choose to directly transmit the capacitance data to a processing system in the terminal, and then the processing system performs the calculation of the current touch parameter based on the capacitance data. That is, in the present application, the method for acquiring the current touch parameter by the terminal may include the following steps:
step 201, receiving capacitance data sent by a touch screen.
Step 202, determining the current touch parameter according to the capacitance data.
It can be understood that, in the embodiment of the present application, after the touch screen detects and obtains the capacitance data, the touch screen may also directly determine the touch parameter corresponding to the touch operation based on the capacitance data generated by the touch operation. That is to say, in the present application, the method for the terminal to obtain the current touch parameter may further include the following steps:
and step 203, receiving the current touch parameter sent by the touch screen.
In summary, in the present application, when the terminal acquires the touch parameter corresponding to the touch operation, the terminal may first acquire capacitance data detected by the touch screen, and then perform data operation in the processing system to determine the corresponding touch parameter; touch parameters calculated and obtained by the touch screen based on the detected capacitance data can also be directly obtained.
Fig. 3 is a second structural diagram of a method for reporting a touch screen, and as shown in fig. 3, a register may be disposed in the touch screen in the terminal. Wherein the register may be used to store a breakpoint threshold.
It should be noted that, in the embodiment of the present application, when performing point reporting processing according to the current touch parameter and the point reporting threshold, the processor in the terminal may determine whether to report based on the point reporting threshold, or the touch screen in the terminal may directly determine whether to report.
Correspondingly, in an embodiment of the present application, fig. 4 is a schematic view illustrating an implementation flow of a touch screen point reporting method, as shown in fig. 4, if a touch screen in a terminal determines whether to perform reporting processing based on a point reporting threshold, the terminal may further include the following steps after setting the point reporting threshold based on the current illumination intensity and the preset illumination threshold, that is, after step 102, the terminal implements the touch screen point reporting method:
and step 104, acquiring an initial threshold corresponding to the touch screen.
In the embodiment of the application, the touch screen in the terminal may first read the pre-stored initial threshold from the register. The initial threshold may be a previous reporting threshold corresponding to a previous touch operation.
And 105, if the report point threshold is different from the initial threshold, updating the initial threshold by using the report point threshold.
In the embodiment of the application, after the touch screen in the terminal obtains the initial threshold corresponding to the touch screen, the touch screen may compare the report point threshold with the initial threshold, and if the report point threshold is not the same as the initial threshold, the touch screen may replace the initial threshold with the report point threshold, that is, the report point threshold corresponding to the current touch parameter is used to update the previous report point threshold.
According to the touch screen point reporting method provided by the embodiment of the application, when touch operation is detected, a terminal acquires current illumination intensity and current touch parameters corresponding to the touch operation; setting a report point threshold value based on the current illumination intensity and a preset illumination threshold value; the preset illumination threshold is used for overcoming the interference of an optical signal on the touch screen; and performing point reporting processing according to the current touch parameter and the point reporting threshold value. Therefore, in the application, the terminal can detect the illumination brightness corresponding to the current environment, and then the preset illumination threshold value is used for setting the point reporting threshold value adaptive to the current illumination brightness, so that when the point reporting threshold value is used for point reporting processing, the occurrence of mistaken point reporting is effectively reduced. That is to say, when illumination intensity is great, the terminal can be adaptability's improvement report threshold value, and then can overcome the interference of light signal to the touch-sensitive screen, has avoided the production of wrong report point, has improved the accuracy and the reliability of touch-sensitive screen, promotes the intelligence at terminal.
Based on the foregoing embodiment, in another embodiment of the present application, fig. 5 is a first flowchart of a point reporting method, and as shown in fig. 5, the method for a terminal to report a point on a touch screen may include the following steps:
The terminal can preset a preset illumination threshold value, wherein the preset illumination threshold value is used for overcoming the interference of the optical signal to the touch screen.
Meanwhile, the terminal may also set a first threshold and a second threshold, where both the first threshold and the second threshold are used for determining the report point threshold. Specifically, the first threshold is greater than the second threshold.
It is understood that in the embodiments of the present application, the larger the hit threshold value is, the more difficult hit is to trigger, and the smaller the hit threshold value is, the more likely hit is to trigger.
For example, in the embodiment of the present application, the terminal may set the first threshold to 80 and the second threshold to 50.
And step 302, acquiring the current illumination intensity and the current touch parameter.
After receiving the touch operation, the terminal may first obtain the current illumination intensity and the touch parameter corresponding to the touch operation. The terminal can acquire the current illumination intensity through the configured optical sensor, and can determine the current touch parameter through the configured touch screen.
Specifically, the current touch parameter may include a touch position and a touch point value corresponding to the touch operation.
In step 303, is the current illumination intensity greater than a preset illumination threshold? If yes, go to step 304, otherwise go to step 305.
The terminal compares the current illumination intensity with a preset illumination threshold value to obtain a comparison result, and then sets a report threshold value according to the comparison result, so that the report threshold value adaptive to the current illumination intensity can be further set based on the current illumination intensity.
If the current illumination intensity is greater than the preset illumination threshold, the terminal needs to set a larger threshold to judge whether to perform reporting processing, and therefore, the first threshold is set as a reporting threshold.
If the current illumination intensity is not greater than the preset illumination threshold, the terminal may set a second threshold having a smaller value as the report point threshold.
After the terminal determines the report point threshold, the report point value in the current touch parameter can be compared with the report point threshold, so that whether report point processing is performed on the current touch parameter is judged according to the comparison result.
And step 307, reporting the touch position.
If the report point value in the touch parameter is greater than or equal to the report point threshold value, the report point can be triggered, and the touch position is reported.
And step 308, no point reporting processing is performed.
If the report point value in the touch parameter is smaller than the report point threshold value, the report point cannot be triggered, and the terminal does not perform report point processing.
In summary, in the present application, the terminal determines whether the illumination intensity reaches the preset light intensity threshold, and if so, sets the touch screen to adopt a larger second threshold; if the touch screen does not meet the preset threshold value, the touch screen is set to adopt a second report threshold value, so that the threshold value of triggering report points can be improved along with the improvement of the current illumination intensity, and the problem of false report points of the touch screen caused by the interference of strong light signals is solved.
Fig. 6 is a flowchart of a point reporting method, and as shown in fig. 6, the method for the terminal to report the point on the touch screen may include the following steps:
The terminal can preset a preset illumination threshold value, wherein the preset illumination threshold value is used for overcoming the interference of the optical signal to the touch screen.
Meanwhile, the terminal can also set a reference report point, wherein the reference report point can be used for determining a report point threshold value. Specifically, the reference report point may represent an average size of the historical report points, and may also represent a report point value corresponding to a condition of moderate ambient light intensity.
It is understood that in the embodiments of the present application, the larger the hit threshold value is, the more difficult hit is to trigger, and the smaller the hit threshold value is, the more likely hit is to trigger. For example, in the embodiment of the present application, the terminal may set the reference report point to 60.
And step 402, acquiring the current illumination intensity and the current touch parameter.
After receiving the touch operation, the terminal may first obtain the current illumination intensity and the touch parameter corresponding to the touch operation. The terminal can acquire the current illumination intensity through the configured optical sensor, and can determine the current touch parameter through the configured touch screen.
Specifically, the current touch parameter may include a touch position and a touch point value corresponding to the touch operation.
And 403, calculating a ratio value of the current illumination intensity to a preset illumination threshold value.
The terminal carries out proportional operation on the current illumination intensity and the preset illumination threshold value to obtain a proportional value between the current illumination intensity and the preset illumination threshold value, and then the setting of the point reporting threshold value can be carried out according to the proportional value, so that the point reporting threshold value adaptive to the current illumination intensity can be further set based on the current illumination intensity.
If the proportion value is less than 1, the terminal can determine that the current ambient brightness does not generate large interference on the touch screen, and therefore the reference report point can be directly set as the report point threshold value.
If the proportional value is greater than or equal to 1, the terminal may consider that the current ambient brightness may cause great interference to the touch screen, and therefore may perform multiplication on the proportional value and the reference report point, and set the product of the two as the report point threshold.
Step 405 is the hit threshold and the initial threshold the same? If yes, go to step 406, otherwise go to step 407.
If the terminal judges whether the touch screen is used for reporting the point, after the point threshold is determined, the touch screen may read an initial threshold from the register, where the initial threshold may be a previous point threshold corresponding to a previous touch operation.
The touch screen may then compare the hit threshold with the initial threshold to determine whether the two are the same.
If the report point threshold value is different from the initial threshold value, the touch screen can replace the initial threshold value with the report point threshold value, namely, the report point threshold value corresponding to the current touch parameter is used for updating the previous report point threshold value.
If the reporting point threshold is the same as the initial threshold, no update process is required.
Step 408 is the hit value greater than or equal to the initial threshold? If yes, go to step 409, otherwise go to step 4010.
And the terminal determines a reporting threshold, updates the initial threshold by using the reporting threshold, and then compares the reporting value in the current touch parameter with the initial threshold so as to judge whether to report the current touch parameter according to the comparison result.
And step 409, reporting the touch position.
If the report value in the touch parameter is greater than or equal to the initial threshold value, the report value can be triggered to report the touch position.
And step 4010, no reporting point processing is performed.
If the report value in the touch parameter is smaller than the initial threshold value, the report cannot be triggered, and the terminal does not perform report processing.
In summary, according to the point reporting method for the touch screen provided by the application, the terminal determines whether the current illumination intensity reaches the preset illumination threshold, and if the current illumination intensity is greater than or equal to the preset illumination threshold, the terminal can set a higher point reporting threshold, so that the threshold for triggering point reporting can be increased along with the increase of the current illumination intensity, and therefore the problem of point false reporting caused by interference of a strong light signal on the touch screen is solved.
According to the touch screen point reporting method provided by the embodiment of the application, when touch operation is detected, a terminal acquires current illumination intensity and current touch parameters corresponding to the touch operation; setting a report point threshold value based on the current illumination intensity and a preset illumination threshold value; the preset illumination threshold is used for overcoming the interference of an optical signal on the touch screen; and performing point reporting processing according to the current touch parameter and the point reporting threshold value. Therefore, in the application, the terminal can detect the illumination brightness corresponding to the current environment, and then the preset illumination threshold value is used for setting the point reporting threshold value adaptive to the current illumination brightness, so that when the point reporting threshold value is used for point reporting processing, the occurrence of mistaken point reporting is effectively reduced. That is to say, when illumination intensity is great, the terminal can be adaptability's improvement report threshold value, and then can overcome the interference of light signal to the touch-sensitive screen, has avoided the production of wrong report point, has improved the accuracy and the reliability of touch-sensitive screen, promotes the intelligence at terminal.
