Claim 9:
10. A terminal device, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the terminal device to perform following operations:
recognizing a collected environmental image;
determining at least one to-be-recognized region in the environmental image, wherein the to-be-recognized region comprises a specified body part used to control a terminal device, wherein the environmental image comprises images of a plurality of users, and determining at least one to-be-recognized region in the environmental image comprises:
for each of the plurality of users in the environmental image, generating a focus region corresponding to the respective user based on an overlapping region between a face region of the respective user and a body region of the respective user;

monitoring a target body part movement in the to-be-recognized region, wherein the target body part movement is a movement triggered by the specified body part; and
performing at least one of the following:
in response to determining that the target body part movement is consistent with a preset activation movement, tracking and monitoring a target body part movement in a target to-be-recognized region, wherein the target to-be-recognized region is a to-be-recognized region in which a target body part movement consistent with the activation movement is located; or
in response to determining that the target body part movement in the target to-be-recognized region is a preset control movement, controlling the terminal device to perform a function operation corresponding to the control movement.
