S10. Establish a coordinate system of the touch area of the terminal, where the lower left is the touch coordinate origin A ₀ (0, 0), and the upper right is the touch coordinate maximum point A _max (x _max , y _max ); the terminal touch The area includes a normal area, a special area on the left side, and a special area on the right side.

In this step, a coordinate system of the touch area of the terminal is established, and the touch area of the terminal is located in the first quadrant. The coordinate data of all touch points on the touch area is made 0 or a positive number. The first quadrant refers to a coordinate system in which the X and Y values of the coordinates are greater than zero.

The terminal has a narrow border or no border. When the user holds the terminal, the finger or the palm is easily in contact with the touch area of the terminal.

As shown in FIG. 4, the touch area of the terminal includes a left special area Z1, a right special area Z2, and a common area Z3 between the left special area and the right special area. The zone Z1 and the right special zone Z2 are both arranged in a rectangular shape.

Two input devices are virtualized on the terminal, one input device is assigned to the normal zone Z3, and one input device is assigned to the left special zone Z1 and the right special zone Z2.

In specific implementation, when the touch screen driver of the terminal is initialized, two input devices (input), such as input device 0 (input0) and input device 1 (input1), are registered through the input_register_device() instruction. And an input device is allocated for each partition by the input_allocate_device() instruction, for example, the common area corresponds to the input device 0, the left special area and the right special area correspond to the input device 1.

After registering the two input devices, the upper layer identifies whether the current user touch area is a normal area or a special area according to the naming of the input device reported by the driver layer, and the upper layer has different processing manners.

The upper layer of the embodiment of the present invention generally refers to a framework layer, an application layer, and the like. In a system of a terminal, a customized system such as android or IOS usually includes an underlying layer (physical layer, a driving layer) and an upper layer (a framework layer, an application layer). The direction of the signal flow is: the physical layer (touch panel) receives the touch operation of the user, the physical press changes to the electrical signal TP, and the TP is transmitted to the driving layer, and the driving layer analyzes the pressed position to obtain the position point. The specific coordinates, duration, pressure and other parameters are uploaded to the framework layer. The communication between the framework layer and the driver layer can be realized through the corresponding interface. The framework layer receives the input device of the driver layer and parses the input. The device, thereby selecting to respond or not responding to the input device, and passing the valid input up to which specific application to satisfy the application layer to perform different application operations according to different events.

S20. Collect coordinate data of a touch point of the user on the touch area of the terminal.

In this step, when a touch point is detected on the touch area of the terminal, and the touch time reaches a preset time threshold, the coordinate data of the touch point is collected, and the coordinate data may include only the x coordinate value, and the coordinate The data can also include both x-coordinate values and y-coordinate values.

In this step, the collected user has multiple touch points on the touch area of the terminal, such as, in general, When the terminal is held by one hand, the finger or the palm has four touch points on the touch area of the terminal.

After receiving the reported event in the framework layer (the reported event includes the input device and the parameters of the touch point, etc.), firstly, according to the naming of the input device, which region is identified, the driver layer (kernel) identification in the above step In the special partition touch, the input device reported to the framework layer on the driver layer is input1, instead of using input0 to report, that is, the framework layer does not need to determine which partition the current touch point is in, nor the size of the partition. And the position, the judgment operation is completed on the driving layer, and the driving layer not only reports which input device is specifically, but also reports various parameters of the touch point to the frame layer, such as pressing time, position coordinates, pressure size, etc. Wait.

It should be noted that after receiving the reported event, the framework layer reports to the application layer through a single-channel to multi-channel mechanism. Specifically, the channel is first registered, the reported event is transmitted through the channel, and the event is listened to by the listener, and the event is transmitted to the corresponding application module through different channels to generate different application operations, where the application The module includes common applications such as camera and contacts; it generates different application operations. For example, in the camera application, when the user clicks in a special zone, it will produce different operations such as focusing, shooting, and adjusting camera parameters. It should be noted that before the report event is delivered to the listener, it is a single channel. After the listener listens, the reported event is multi-channel, and multiple channels exist at the same time. The advantage is that it can be transmitted to different application modules at the same time, and different application modules are generated. Different response operations.

Optionally, the specific implementation of the foregoing steps is: using an object-oriented manner, defining a category and an implementation manner of the common partition and the special partition, and after determining that the special partition is used, converting the coordinates of the touch points of different resolutions by using the EventHub function. For the coordinates of the LCD, define a single-channel function (such as serverchannel and clientchannel, etc.). The function of this function is to pass the event to the event manager (TouchEventManager) through the channel after receiving the reported event, and listen through the listener. The event is transmitted to multiple response application modules simultaneously or one by one through multiple channels, or can be transmitted only to one of the application modules, and application modules such as camera, gallery, etc., and different application modules generate corresponding operations. Certainly, the specific implementation of the foregoing steps may also be implemented in other manners, which is not limited by the embodiment of the present invention.

S30. If the coordinate data of the touch point satisfies: 0<x<W1, it is determined that the touch point is located in a special area on the left side; if the coordinate data of the touch point satisfies: W-W2<x<W, the touch point is determined. Located in the special area on the right side; where x represents the X-axis coordinate data in the coordinate data, W1 represents the width of the special area Z1 on the left side, W2 represents the width of the special area Z2 on the right side, and W represents the touch area of the terminal. width.

In this step, the coordinate data of the touched point collected in step S20 is compared with W1, W-W2, and W to determine that the touched point belongs to any one of the left special area, the right special area, and the normal area. The left special area and the right special area are both rectangular, and the X-axis coordinate data in the coordinate data of the touch point is directly determined, and the area to which the touch point belongs can be determined. The width W1 of the special area on the left side may be the same as the width W2 of the special area on the right side, that is, the left special area and the right special area are symmetrically distributed on the terminal touch area.

According to the embodiment of the present invention, the coordinate data of the touch point on the touch area of the terminal is collected, and the coordinate data of the touch point and the W1, W-W2, and W are determined, and the touch point can be accurately determined.
