A method and system for automatically adjusting mobile phone controls through left and right hands

technical field

The invention relates to the technical field of information control, in particular to a method and system for automatically adjusting controls of a mobile phone through left and right hands.

Background technique

The touch screen brings great convenience to the user's operation, but there are differences in personal use methods. Some people like to hold the mobile phone with their left hand, and some people like to hold their mobile phone with their right hand. When using mobile phone controls (taking virtual buttons as an example), especially when a large-screen mobile phone is used for one-handed operation, we originally wanted to click the rightmost virtual button (such as the return button back), but in fact our fingers Belly has touched the leftmost virtual button (such as the menu button menu), and at this time, some operations that are not our intention will be performed. At this time, if the position of the virtual button can be automatically changed, then this problem can be solved very well .

At present, there are already some technical solutions that use the judgment of left and right hands, such as judging the angle of use of the mobile phone to identify the left and right hands, or installing some sensors on both sides of the mobile phone to judge the left and right hands. high. These solutions need to add new devices, and cannot directly judge and identify whether the current user is operating with the left hand or the right hand by counting the sliding track of the touch screen, so as to adjust the position of the virtual button.

Example

As shown in Figure 3, the present embodiment automatically adjusts the method for mobile phone controls through the left and right hands, including the following steps:

Step 1: Collect the data coordinates of the user's sliding operation on the touch screen;

The touch screen device can collect the coordinate data of the finger, for example, collect 2 coordinate point data, that is, the coordinate data of the start point and the end point of the slide, from (x_0, y_0) to (x_1, y_1).

Step 2: upload the two coordinate data of the sliding to the application layer, and the application layer calculates the slope of the sliding.

Usually, the coordinate system of the touch screen is the touch origin at the upper left of the picture, namely (0, 0) point, and the maximum resolution point of the touch screen at the lower right, namely (x_max, y_max) point, for left-handed operation, as shown in Figure 1 As shown, the slope k=(y_1-y_0)/(x_1-x_0), then if it is a left-handed operation, whether it is sliding to the left or sliding to the right, the slope of any point must be greater than 0, that is, it must be a positive number (For example, slide to the left, x becomes smaller, y becomes smaller, slide to the right, x becomes larger, y becomes larger); and for the right-handed operation, as shown in Figure 2, whether it is sliding to the left or going Swipe right, the slope of any point must be less than 0, and must be a negative number (for example, slide to the left, x becomes smaller, y becomes larger, slide to the right, x becomes larger, y becomes smaller).

Step 3: If the acquired slope is greater than 0, it means left-handed operation; if it is less than 0, it means right-handed operation; if it is close to 0 or infinite, it means that the user swipe the touch screen in a direction close to vertical or horizontal.

Step 4: Adjust the position of the control according to the left and right hands that have just been identified. For example, if it is recognized as a left-handed operation, then adjust the commonly used return key virtual button to the left of the screen. The virtual button is adjusted to the right side of the screen. If it is detected that it is close to vertical or sliding in the vertical screen direction, then no adjustment will be made.

All virtual buttons have their own location area coordinates. For example, the resolution of the touch screen is (100, 100), and the virtual buttons are often under the touch screen. The coordinate area occupied by the menu is (0,70) to (30,100) ), the area occupied by the home virtual button is (30,70) to (60,100), and the area occupied by the return is (60,70) to (90,100). Each virtual button is a square coordinate area. When a certain If the area is clicked, then judging the coordinate range of the area, it is known that the virtual button was pressed, and then the event of the virtual button is passed to the upper layer.

The method used to adjust the position of the virtual button is, for example, if we detect that the left-handed operation is currently performed, when the lower left corner is detected to be touched, the menu button event should have been reported, but we can report the return button event, and this is done Switching of virtual keys.

In order to better implement the present invention, before step 1, it also includes setting the interface mode switch. When the interface mode switch is set to on, step 1 is performed; when the interface mode switch is set to off, step 1 is not performed.

As shown in Figure 4, the present embodiment automatically adjusts the mobile phone control system by identifying left and right hands, including sequentially connected data acquisition modules, slope calculation modules, slope judgment modules and execution modules;

The data collection module is used to collect the coordinate data of the sliding operation performed by the user on the touch screen;

The slope calculation module calculates the slope of the trajectory through the data collected by the data acquisition module;

The slope judgment module is used to compare the slope calculated by the slope calculation module with 0. If it is greater than 0, it is judged to be a left-handed operation. If the slope is less than 0, it is judged to be a right-handed operation. If it is close to 0 or infinite, it means that the user Swipe the touch screen in a direction close to vertical or horizontal;

The execution module adjusts the position of the mobile phone control according to the judgment result obtained by the slope judgment module.

The execution module includes a virtual key setting module and a virtual key adjustment module, the virtual key setting module is used to determine which virtual key is pressed, and then the event of this virtual key is passed to the upper layer; the virtual key adjustment The module adjusts the position of the virtual button according to the data transmitted by the virtual button setting module.
