Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a method for controlling a touch screen of a mobile terminal according to an embodiment of the present invention, where the method may be performed by a touch screen control apparatus of the mobile terminal, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in the mobile terminal. As shown in fig. 1, the method includes:
step 101, detecting a multi-point touch event acting on a terminal touch screen.
The multi-point touch event is an event that a plurality of touch operations are simultaneously performed on the touch screen due to the simultaneous touch operations generated at different positions of the touch screen. For example, when the user holds the mobile terminal with the right hand, and performs a click operation on the touch screen with the finger of the right hand, the palm of the right hand touches an edge of the screen, and then a multi-touch event on the touch screen is detected. For another example, when the user holds the mobile terminal with both hands and performs a clicking operation on the touch screen with the fingers of the right hand, the palm of the left hand or the fingers of the left hand touch the left edge area of the screen carelessly, and then a multi-touch event on the touch screen is detected.
The terminal described in this embodiment includes, but is not limited to, a mobile phone, a tablet computer, and other devices integrated with a touch screen. The mobile terminal can be added with an edge false touch prevention setting option, and the edge false touch prevention function is automatically started by the system according to actual conditions or the user automatically starts the false touch prevention function according to personal requirements. For example, the system can detect the current posture of the mobile terminal, and automatically start the function of preventing false touch when the mobile terminal is in a vertical screen state; when the mobile terminal is in a horizontal screen state, the function of preventing false touch is not started. In this embodiment, it is assumed that the false touch prevention function of the terminal is already in an on state.
And 102, acquiring the contact area and the pressure value of each touch point corresponding to the multi-point touch event.
The contact area of the touch point in this embodiment includes a contact area value and a contour of the contact surface. For example, the shape of a finger, such as an ellipse of a certain size, may be regarded as the shape of a normal touch point, and a long bar shape or an irregular shape may be regarded as the shape of a false touch point.
The pressure value of the touch point can be an average pressure value or a maximum pressure value of the touch point in the whole touch operation process, and is preferably the maximum pressure value.
The touch screen adopted by the existing mobile terminal comprises a resistance type touch screen, a capacitance type touch screen, a piezoelectric type touch screen and the like, when a user touches the touch screen, the touch screen can detect touch information, and then the touch operation of the user is identified. Taking a capacitive touch screen as an example, the touch screen can sense the change of capacitance, when a user touches the touch screen, the touch screen senses the change of capacitance and recognizes touch information of each touch point, the touch information includes a contact area and a pressure value, and may also include information such as coordinates of the touch point and the number of touched fingers (the number of the touch points), and after recognizing the touch information, the touch information is reported to an upper layer through an input system, so that the terminal determines a wrong touch point according to the touch information of each touch point.
For example, the pressure value of the touch operation may be obtained through a pressure sensor integrated on the surface of the mobile terminal. Preferably, the touch screen of the mobile terminal in this embodiment is a pressure sensing screen, the pressure sensing screen is a novel touch screen of the mobile terminal, and a pressure sensor is integrated in the pressure sensing screen, so that the touch screen not only can accurately sense the touch position of a user, but also can identify the force magnitude when the user touches, that is, the pressure magnitude received when the touch screen is touched by the user can be detected, and the pressure magnitude is recorded as a pressure value corresponding to the touch operation. When the user's hand leaves the touch screen, the pressure value is 0.
And 103, determining a false touch point in each touch point according to the contact area and the pressure value of each touch point so as to control the touch screen not to respond to the touch operation of the false touch point.
Generally, the contact area corresponding to the normal touch operation of the user is not too large in a range, and the contact area corresponding to the false touch operation is often large, for example, the contact area between the false touch operation of the palm on the edge of the touch screen and the touch screen is large; the pressure value corresponding to the error touch operation of the user is often smaller due to the fact that the user accidentally touches the touch screen, and the pressure value corresponding to the normal touch operation is larger relative to the error touch operation. Therefore, in this step, determining the false touch point in each touch point according to the contact area and the pressure value of each touch point may specifically include: and if the contact area of the touch point is larger than the preset area threshold value and the pressure value is smaller than the preset pressure threshold value, determining that the touch point is a false touch point. The preset area threshold and the preset pressure threshold are preset and used for distinguishing whether the touch point is a normal touch point or a false touch point. The preset area threshold may specifically be a maximum contact area of the normal touch point, and the preset pressure threshold may specifically be a minimum pressure value of the normal touch point.
Specifically, the control of the touch screen not responding to the touch operation of the false touch point may be implemented by not reporting the touch information of the false touch point, or by reporting the touch information to an upper layer without processing the upper layer.
According to the control method of the mobile terminal touch screen, the mistaken touch point in the multiple touch points corresponding to the multi-point touch event is determined according to the contact area and the pressure value of the touch point, so that the touch screen is controlled not to respond to the touch operation of the mistaken touch point, and the mistaken touch prevention of the mobile terminal touch screen is realized. In addition, because the mistaken touch points are determined according to the contact areas and the pressure values of the touch points, the accuracy of the determination mode of the mistaken touch points is higher, and the mistaken touch can be prevented on the touch screen of the terminal more efficiently and accurately.
Fig. 2 is a flowchart illustrating another method for controlling a touch screen of a mobile terminal according to an embodiment of the present invention. As can be seen from the foregoing embodiments, in general, a touch point with a contact area larger than a preset area threshold among a plurality of touch points of a multi-touch event is determined as a touch error point. However, when the contact areas of the plurality of touch points are all small, there is a possibility that a touch error occurs. Therefore, the present embodiment is optimized based on the above embodiment, and "determining the false touch point in each touch point according to the contact area and the pressure value of each touch point" is optimized as follows: determining that the contact area of each touch point is smaller than a set area value, and taking each touch point as a current touch point; comparing the pressure value of the current touch point with a preset pressure threshold value; and if the pressure value is smaller than a preset pressure threshold value, determining the current touch point as a false touch point. The method provided by the embodiment is suitable for the situation of processing the false touch operation when the contact area of each touch point in the multi-point touch event is smaller than the set area value.
Correspondingly, as shown in fig. 2, the method provided by the present embodiment includes:
step 201, detecting a multi-point touch event acting on a terminal touch screen.
Step 202, obtaining a contact area and a pressure value of each touch point corresponding to the multi-point touch event.
And 203, determining that the contact area of each touch point is smaller than a set area value, and taking each touch point as a current touch point.
Wherein, the set area value can be the same as a preset area threshold value.
And step 204, judging whether the pressure value of the current touch point is smaller than a preset pressure threshold value, if so, executing step 205, otherwise, executing step 206.
When the contact area of each touch point in the multi-point touch event is smaller (smaller than a set area value), whether the pressure value of the touch point is smaller than a preset pressure threshold value or not is further judged, and then the mistaken touch point in the multi-point touch event is identified.
And step 205, determining the current touch point as a false touch point, and controlling the touch screen not to respond to the touch operation of the false touch point.
And step 206, determining the current touch point as a normal touch point, and controlling the touch screen to respond to the touch operation of the normal touch point.
According to the method provided by the embodiment, when the contact area of each touch point in the multi-point touch event is determined to be smaller than the set area value, the touch point of which the pressure value is smaller than the preset pressure threshold value is determined to be the wrong touch point, and the touch screen is controlled not to respond to the touch operation of the wrong touch point, so that the problem that whether the wrong touch point exists cannot be judged when the contact area of each touch point is smaller than the preset area threshold value due to the fact that the touch point of which the contact area in the multi-point touch event is larger than the preset area threshold value is used as the wrong touch point for preventing wrong touch in the prior art is solved, the method enables the range of application of the wrong touch prevention function of the terminal to be wider, and enables the terminal to effectively prevent wrong touch.
On the basis of the foregoing embodiment, the comparing the pressure value of the current touch point with a preset pressure threshold includes: determining a preset pressure threshold corresponding to the current touch point according to the touch type of the current touch point; and comparing the pressure value of the current touch point with the preset pressure threshold value. Wherein the touch type comprises single click, double click, sliding or long press.
It can be understood that the touch pressures corresponding to different types of touch operations are different, and generally, the pressure values of the sliding, clicking, double clicking and long-pressing touch operations sequentially rise, so that when an error touch point is determined according to the pressure value of the touch point, the touch type of the touch point can be used as a basis for determining the error touch point. The preset pressure threshold corresponding to each touch type can be preset, when the contact area of the current touch point is smaller than a set area value, the preset pressure threshold corresponding to the current touch point is determined according to the touch type of the current touch point, and if the pressure value of the current touch point is smaller than the preset pressure threshold, the current touch point is determined to be a wrong touch point.
On the basis of the above embodiment, after determining that the contact areas of the touch points are all smaller than the set area value and taking the touch points as the current touch points, the method further includes: and if the pressure value of the current touch point is greater than or equal to a preset pressure threshold value, determining the current touch point as a normal touch point, and controlling the touch screen to respond to the touch operation of the normal touch point.
On the basis of the above embodiment, after determining that the contact areas of the respective touch points are all smaller than the set area value, the method further includes: and determining the touch point with the maximum pressure value in all the touch points as a normal touch point, and controlling the touch screen to respond to the touch operation of the normal touch point.
