Alternative embodiment 2

Through the trajectory, an alternative embodiment of the present invention establishes a set of stereo matching trajectory directions. 13 is a schematic diagram of a trajectory detection matching process according to an alternative embodiment of the present invention, wherein the operation of the trajectory of the mobile phone includes a three-dimensional stereo direction including changes in the x, y, and z-axis directions, as shown in FIG. Changes to detect the gestures of the phone, the specific steps and principles are as follows:

Step S1301, FIG. 14 is a stereoscopic trajectory detection diagram according to an alternative embodiment of the present invention. As shown in FIG. 14, the present invention divides the space into three directions of x, y, and z. When the phone clicks on the input box and turns on the gesture input method, this is the startup gesture detection;

Step S1302, after the acceleration sensor detects the mobile phone speed specification value, the system determines that the user has started the gesture operation, and records the initial position of the mobile phone movement as the mobile center position of the mobile phone, that is, the x, y, and z axis intersections;

Step S1303: When the mobile phone moves, the location track of the mobile phone is collected every 0.1 seconds, and the movement track of the entire mobile phone when the user inputs is recorded;

Step S1304, when detecting that the mobile phone has not moved for more than 0.5 seconds, it is determined that the user's input is completed, and the mobile track recorded by the mobile phone is analyzed and matched;

In step S1305, the mobile phone samples at a frequency of 0.1 per second, and takes 2 seconds as a gesture action, that is, there are 20 sampling points. For example, the operation of the serial number of Table 1 is taken as an example, and the manual operation of the user includes the first right. Move + up 90 degrees; matching the phone track includes the following two steps:

1. Analyze the sampling points of the first 40% of the collected trajectories, and determine that the area with the most trajectory is the user's first moving trajectory. For operation No. 31 in Table 1, 40% of the points are collected, that is, the first 8 sampling points. When the track point is the most in the range of 30 degrees from the right axis of the x, it is determined that the user shifts to the right when the first operation is performed.

2. The second step is to determine the position of the last 20% of the trajectory of the mobile phone. Taking the No. 31 gesture as an example, 20% of the trajectory points are two. When detecting the last two points on the plane formed on the right side of x and above the z-axis, When the angle is less than 15 degrees, and the horizontal distance of the z-axis is about 5 cm, it is determined that the trajectory of the user's final movement falls on the upper right plane of x and z;

Step S1306, in conjunction with the two matching processes in step S1305, finally matching the gesture track.

Alternative embodiment three

Track point location area matching is set forth below, and Figures 15a-15b are exploded trajectory detection diagrams in accordance with an alternate embodiment of the present invention. Taking the x, y axis plane as an example, the gesture trajectory detection is divided into two steps:

The first step is to detect the area where the first 40% of the trajectory points fall. As shown in Figure 15a, the first step of the gesture has four kinds of trajectories, four kinds of trajectories: left, right, forward, and backward, as shown in Figure 15a. Taking the plan view of the x and y axes as an example, the area with the most track points in the range of 30 degrees in the x and y directions is considered to be the change of the corresponding direction track. For example, the 30 degree area on the right side of the x axis is the most track point. The area that can match the gesture-compliant operation includes gestures 26 to 32;

The second step of the test is to judge the last 20% of the track points falling into the area, which is introduced in the x and y planes of Figure 15b.

The track point falls at most into the area of the center circle of the x and y axes (directly 5cm). We believe that the gesture finally returns to the origin, and the gestures corresponding to the corresponding operation are 2, 9, 20, and 27. As shown in the above steps, the judgment gesture is 27 ;

The trajectory falls within 5cm of the x-axis and is not within the central circle. It is determined that the end user falls to the right of the x-axis. The matching gestures include numbers 6, 28, combined with the first detection, and the judgment is the 28th gesture;

When the trajectory falls into the x and y planes with an x and y axis distance of about 5 cm, we match the gestures including the 4, 25 gestures, combined with the first detection, and determine the 25th gesture.

Through the above detection means, the gesture trajectory of the user can be determined.
