A gesture control method for a wearable system, comprising: creating, by a wearable system, a gesture working region and a region of interest, wherein the gesture working region is defined according to user experience where during usage a user tends to make a gesture, the region of interest is a part of, or the entire of, a shooting area of a first camera, and the first camera is comprised in the wearable system and is fixed relative to the wearable system; obtaining, by the wearable system, a location parameter of the wearable system, the location parameter comprising a direction or an angle; adjusting, by the wearable system, the region of interest according to the location parameter by adjusting an angle of a reflexive mirror configured to reflect an image in the region of interest into the shooting area of the camera, and/or a shooting angle of the camera by using a rotary motor, so that the region of interest covers the gesture working region; collecting, by the wearable system, a gesture image within the gesture working region, wherein the gesture image comprises a static hand posture and/or a dynamic gesture motion; recognizing, by the wearable system, the gesture image to obtain a gesture instruction; and performing, by the wearable system, a corresponding operation according to the gesture instruction, wherein after the collecting, by the wearable system, a gesture image within the gesture working region, and before the recognizing, by the wearable system, the gesture image to obtain a gesture instruction, the method further comprises: re-adjusting, by the wearable system, the region of interest when the wearable system determines that there is no light spot in the gesture image, so that there is a light spot in a new gesture image collected by the wearable system, wherein the light spot is generated from laser light transmitted by a laser provided in the first camera of the wearable system. creating, by a wearable system, a gesture working region and a region of interest, wherein the gesture working region is defined according to user experience where during usage a user tends to make a gesture, the region of interest is a part of, or the entire of, a shooting area of a first camera, and the first camera is comprised in the wearable system and is fixed relative to the wearable system; obtaining, by the wearable system, a location parameter of the wearable system, the location parameter comprising a direction or an angle; adjusting, by the wearable system, the region of interest according to the location parameter by adjusting an angle of a reflexive mirror configured to reflect an image in the region of interest into the shooting area of the camera, and/or a shooting angle of the camera by using a rotary motor, so that the region of interest covers the gesture working region; collecting, by the wearable system, a gesture image within the gesture working region, wherein the gesture image comprises a static hand posture and/or a dynamic gesture motion; recognizing, by the wearable system, the gesture image to obtain a gesture instruction; and performing, by the wearable system, a corresponding operation according to the gesture instruction, wherein after the collecting, by the wearable system, a gesture image within the gesture working region, and before the recognizing, by the wearable system, the gesture image to obtain a gesture instruction, the method further comprises: re-adjusting, by the wearable system, the region of interest when the wearable system determines that there is no light spot in the gesture image, so that there is a light spot in a new gesture image collected by the wearable system, wherein the light spot is generated from laser light transmitted by a laser provided in the first camera of the wearable system.
