As shown in fig. 4, the operation body performs various input operations on the input interface, and projected light forming the input interface hits the operation body and reflects light outward, in this embodiment, return light after the projected light meets the operation body is acquired.
Step 102: based on the return light, at least a partial gesture contour of the operation body is obtained.
As shown in fig. 4, after the return light is obtained, in the present embodiment, the direction and distance at which the return light meets the operation body may be determined based on the time and angle at which the return light is obtained, so as to obtain at least a partial gesture contour of the operation body.

Or, in this embodiment, when determining whether the at least part of the gesture outline satisfies the preset operation condition, the following method may be implemented:

Furthermore, in this embodiment, when the operation gesture of the operation body is recognized, the at least part of the gesture outline may be compared with a plurality of preset gesture outlines one by one, such as an outline of a palm, an outline of a single-finger operation, an outline of a double-finger operation, and the like, so as to obtain a similarity value between each gesture outline and the at least part of the gesture outlines of the operation body, and finally, the operation gesture corresponding to the gesture outline with the highest similarity value is used as the operation gesture of the operation body. Then, the embodiment determines whether the operation gesture of the operation body meets a preset operation condition, and if the operation gesture is consistent with a preset target gesture, executes an operation instruction on the content corresponding to the at least part of the gesture outline on the input interface.
In an implementation manner, when an operation instruction is executed on content corresponding to at least part of a gesture outline on an input interface in this embodiment, it is necessary to first determine the content corresponding to the at least part of the gesture outline locked on the input interface, and then execute the operation instruction on the content, specifically, in this embodiment, the operation instruction may be executed in the following manner:
firstly, determining a target position of the at least part of gesture outline which is blocked on the input interface, as shown in fig. 7, the target position X on the input interface is blocked by the at least part of gesture outline a, and then executing an operation instruction on content which is correspondingly displayed at the target position on the input interface, such as deleting content such as characters or lines and the like in the part of content;
