Abstract: A device control method, apparatus, and system applicable to the field of smart home technologies. The method includes: recognizing a collected environmental image; determining at least one to-be-recognized region in the environmental image; monitoring a target body part movement in the to-be-recognized region; if it is monitored 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; or if it is monitored that the target body part movement in the target to-be-recognized region is a preset control movement, controlling a terminal device to perform a function operation corresponding to the control movement. The terminal device is controlled by using a target body part movement including two-stage movements.
