These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The disclosure provides a touch reporting method, which can be applied to a terminal, wherein the terminal is provided with a touch screen, the touch screen comprises a screen and a sensor array positioned below the screen, the sensor array comprises a large number of sensors arranged in an array, the sensors are used for detecting touch signals, and the sensors can be pressure sensors.
The touch reporting method provided by the disclosure can be specifically applied to a processor in a terminal, the touch screen can further comprise a touch screen chip, the touch screen chip is connected with the sensor array, the touch screen chip receives a touch signal detected and sent by a sensor in the sensor array, meanwhile, the touch screen chip is connected with the processor, and the touch screen chip sends the touch signal sent by the sensor to the processor, so that the processor executes corresponding operation based on the touch signal.
The terminal can be a mobile phone, a tablet, a wearable electronic device and the like with the structure and the functions.
Fig. 1 is a flowchart illustrating a touch reporting method according to an exemplary embodiment, where the touch reporting method illustrated in fig. 1 includes the following steps:
in step 101, touch signals detected by a plurality of sensors in a sensor array are acquired.
Based on the structure and performance of the touch screen, when touch operation exists on the touch screen, the sensor in the touch area detects a touch signal, when suspended matters exist on the touch screen, the sensor below the suspended matters can also detect the touch signal, and the sensor can also detect the touch signal in other scenes.
In application, the sensor sends the detected touch signal to the touch screen chip, and the touch screen chip can perform digital conversion on the touch signal to obtain a corresponding digital signal, and sends the digital signal to the processor. In this case, the touch signal acquired by the terminal in this step may be a digital signal obtained by digital conversion.
In step 102, a finger touch signal is selected from all the acquired touch signals.
Based on the structural characteristics of the finger, when the finger presses the touch screen, the pressure of the center area of the finger is higher, and the pressure of the edge area of the finger is lower, so that the signal intensity of the finger touch signal detected by the sensor in the center area of the finger is higher than that of the finger touch signal detected by the sensor in the edge area of the finger.
Based on the above characteristics of the finger touch signals generated by the finger pressing operation, the terminal can determine whether a plurality of touch signals which are detected by the plurality of sensors sequentially arranged from inside to outside and have gradually reduced signal intensity exist in all the touch signals, and if so, determine the touch signals detected by the plurality of sensors sequentially arranged from inside to outside as the finger touch signals. The signal intensity of the touch signal detected by the plurality of sensors may be in a gradient decreasing trend.
In practice, the terminal may select the touch signal with the signal intensity greater than the preset intensity from all the acquired touch signals, and then select the finger touch signal from the touch signals with the signal intensity greater than the preset intensity.
When the touch signal is a digital signal, the terminal may select a touch signal having a signal value greater than a preset value from all the acquired touch signals, and then select a finger touch signal from the touch signals having a signal value greater than the preset value.
In step 103, a target touch signal satisfying the target signal strength condition is selected from all the finger touch signals.
In one embodiment, the target signal strength condition defines a target strength threshold, and the terminal may determine the target strength threshold, and select a target touch signal with a signal strength greater than the target strength threshold from all finger touch signals. The target touch signal belongs to a finger touch signal.
The target intensity threshold may be preset, fixed, and obtained directly by the terminal during use, or the target intensity threshold may be variable and determined in real time by the terminal based on current usage information.
In one embodiment, the terminal may determine a current use state of the terminal based on the signal strength of all finger touch signals, and determine a target strength threshold based on terminal information of the terminal, wherein the terminal information includes: the current usage status of the terminal. The current usage state of the terminal is various, for example, a single-finger touch state, a multi-finger touch state, a holding state, and the like.
Under the condition that the touch screen is divided into a main screen and a side screen, when a finger presses on the main screen, as shown in fig. 2, the finger completely covers the sensor, and at this time, the number of touch signals with larger signal intensity is larger; when a finger is pressed on the side screen, as shown in fig. 3, the finger does not completely contact the screen, and the number of touch signals having a greater signal intensity is smaller.
Based on this, the terminal may determine, from among all the finger touch signals, the total number of finger touch signals whose signal strength is greater than the first preset value and finger touch signals whose signal strength is equal to the first preset value, and the number of finger touch signals whose signal strength is less than the first preset value, and determine the current use state based on the total number and the number.
For example, if the total number of the finger touch signals with the signal strength greater than or equal to the first preset value is small, and the number of the finger touch signals with the signal strength less than the first preset value is large, it is determined that the terminal is currently in the holding state.
The connection department of main screen and side screen is the arc structure, and the arc department screen is thicker, and the in-process loss of pressure of touch-control operation is more through screen transmission to sensor, leads to the signal intensity of the touch-control signal that the sensor detected less. When a user holds the terminal, namely the terminal is in a holding state, the finger center area covers the arc-shaped position of the screen, the finger edge area covers other screen areas, the signal intensity of the finger touch signal corresponding to the finger center area and detected by the sensor is small, and the signal intensity of the finger touch signal corresponding to the finger edge area and detected by the sensor is large.
Based on this, in one manner, the terminal may determine whether the signal intensity of the finger touch signal detected in the central area of the finger touch area is less than the signal intensity of the finger touch signal detected in the edge area of the finger touch area, among all the finger touch signals, and determine the current use state of the terminal based on the determination result.
And if the signal intensity of the finger touch signal detected in the central area of the finger touch area is smaller than the signal intensity of the finger touch signal detected in the edge area of the finger touch area, determining that the terminal is currently in a holding state.
When the signal intensity of the finger touch signal detected in the central area is very small, the entire finger touch area in the touch signal diagram is a hollow area, which may be a circular area, a triangular area, or the like, and the shape of the hollow area is determined based on the actual touch condition. And if the terminal determines that the whole finger touch area is a hollow area, determining that the terminal is currently in a holding state.
In another mode, the terminal may determine whether a finger touch area corresponding to a finger touch signal of which the signal intensity is smaller than a second preset value among all the finger touch signals is located in a finger touch total area corresponding to a finger touch signal of which the signal intensity is larger than the second preset value and a finger touch signal of which the signal intensity is equal to the second preset value, and determine the current use state based on a determination result.
And if the terminal determines that the finger touch area corresponding to the finger touch signal of which the signal intensity is smaller than the second preset value is located in the finger touch total area corresponding to the finger touch signal of which the signal intensity is larger than the second preset value and the finger touch signal of which the signal intensity is equal to the second preset value in all the finger touch signals, determining that the terminal is currently in the holding state.
When the second preset value is very small, the whole finger touch area in the touch signal diagram is a hollow area. And if the terminal determines that the whole finger touch area is a hollow area, determining that the terminal is currently in a holding state.
The terminal may pre-establish a correspondence between the usage states of the plurality of groups of terminals and the intensity threshold, and in application, the terminal may determine the target intensity threshold corresponding to the current usage state of the terminal by searching the pre-established correspondence.
For example, a corresponding relationship between a handheld state and an intensity threshold a, a corresponding relationship between a non-handheld state and an intensity threshold b, a corresponding relationship between a single-finger touch state and an intensity threshold c, and a corresponding relationship between a three-finger touch state and an intensity threshold d are pre-established, where the intensity threshold c may be greater than the intensity threshold d.
On the basis of the above embodiment, the terminal information may further include: the hardware performance of the touch screen and the operation of the terminal for determining the target intensity threshold value based on the terminal information can be realized by the following modes: firstly, determining the hardware performance of the touch screen; second, a target intensity threshold corresponding to the current usage state and hardware performance of the terminal is determined.
The touch screen comprises a plurality of TX lines and a plurality of RX lines, the TX lines and the RX lines are arranged in a crossed mode to form a plurality of rectangular sensors, and the distance between one TX line and one adjacent RX line is called pitch.
Based on the above structure of the touch screen, the hardware performance of the touch screen may include at least one of: the number of rectangular sensors (e.g., 16 × 36 or 18 × 36), the size of each rectangular sensor (e.g., 6.5 × 4.6), the number of lines per pitch (single or double lines), the number of channels simultaneously scanned by a Mux (data selector) module in a touch screen chip, etc.
The terminal can pre-establish the corresponding relation among the use state, the hardware performance and the strength threshold value of a plurality of groups of terminals, and in application, the terminal can determine the strength threshold value corresponding to the current use state and the hardware performance of the terminal by searching the pre-established corresponding relation, and determine the corresponding strength threshold value as the target strength threshold value.
In one embodiment, the terminal may pre-establish a corresponding relationship between the charging state and the first intensity threshold, and a corresponding relationship between the non-charging state and the second intensity threshold, and in the application process, after determining that the terminal is currently in the charging state, the terminal determines the first intensity threshold corresponding to the charging state based on the pre-established corresponding relationship, and takes the first intensity threshold as the target intensity threshold.
In step 104, it is determined whether to report the coordinates of the touch points based on the number of the target touch signals and the number of the finger touch signals.
In one embodiment, the terminal may calculate a ratio of the number of the target touch signals to the number of the finger touch signals, determine whether the ratio is greater than or equal to a preset ratio, determine to report the coordinates of the touch points if the ratio is greater than or equal to the preset ratio, and determine not to report the coordinates of the touch points if the ratio is less than the preset ratio. The magnitude of the preset ratio can be set according to experience and needs.
The ratio of the number of target touch signals to the number of finger touch signals can be understood as: the ratio of the finger touch area corresponding to the finger touch signal with a larger signal intensity to the total finger touch area may be referred to as the coverage of the strong signal.
In an embodiment, when the touch screen is divided into a main screen and a side screen, the terminal may only perform touch reporting on the side screen, or only perform touch reporting on the main screen, or perform touch reporting on the main screen and the side screen by using the touch reporting method provided by the present disclosure.
In a scenario where the terminal only performs touch reporting on the side screen by using the touch reporting method provided by the present disclosure, step 102 may be implemented in the following manner: firstly, selecting a touch signal detected by a sensor in a side screen from all acquired touch signals; and secondly, selecting a finger touch signal from the touch signals detected by the sensor in the side screen. In this case, step 104 may be implemented by: and determining whether to report the coordinates of the touch points on the side screen or not based on the number of the target touch signals and the number of the finger touch signals.
According to the method, after the terminal acquires the touch signals detected by the sensors in the sensor array, the finger touch signals are selected from all the acquired touch signals, the target touch signals meeting the target signal strength condition are selected from all the finger touch signals, and whether the touch point coordinates are reported or not is determined based on the number of the target touch signals and the number of the finger touch signals, so that a novel touch reporting method is provided, and the touch performance of the terminal is improved.
