Gesture control method for wearable system and wearable system

A gesture control method for a wearable system, the method comprising:

• creating, by a wearable system, a gesture working region and a region of interest, wherein the region of interest is within a shooting area of a first camera, and the first camera is comprised in the wearable system;
• obtaining, by the wearable system, a location parameter of the wearable system;
• adjusting, by the wearable system, the region of interest according to the location parameter, so that the region of interest overlaps with the gesture working region, wherein adjusting the region of interest comprises:
• obtaining, by the wearable system by using the location parameter, a tilting angle when the wearable system tilts upward or downward, wherein the tilting angle is used to indicate an upward deviation angle or a downward deviation angle of the wearable system;
• calculating, by the wearable system according to the tilting angle, a second adjustment angle of the first camera by using a second relation, wherein the second relation is determined by the wearable system according to a first coordinate system, a second coordinate system, and a third coordinate system;
• and
• adjusting, by the wearable system according to the second adjustment angle, the first camera so as to adjust the region of interest.

A wearable system comprising:

• a first camera, a sensor, a processor, and a bus, wherein the first camera and the sensor are coupled to the processor through the bus;
• a memory storing a program to be executed in the processor, the program comprising instructions to create a gesture working region and a region of interest, wherein the region of interest is within a shooting area of the first camera;
• wherein the sensor is configured to obtain a location parameter of the wearable system and provide to the processor;
• wherein the instructions cause the processor to
• calculate, based on the location parameter, a first adjustment angle by using a first relation, wherein the first relation is determined by the wearable system according to a first coordinate system, a second coordinate system, and a third coordinate system, the first coordinate system is created by the wearable system according to the gesture working region, the second coordinate system is created by the wearable system according to the region of interest, and the third coordinate system is created by the wearable system according to the wearable system itself,
• adjust the region of interest according to the location parameter by adjusting the camera according to the first adjustment angle, so that the region of interest overlaps with the gesture working region;
• wherein the first camera collects a gesture image within the gesture working region, wherein the gesture image comprises a static hand posture and/or a dynamic gesture motion;
• and
• wherein the instructions cause the processor to recognize the gesture image collected by the first camera, to obtain a gesture instruction, and perform a corresponding operation according to the gesture instruction.
