Electronic device for recognizing user's gesture

According to an embodiment disclosed in the present document, a gesture-based command execution method may comprise the operations of: acquiring a command from a user by using a sensor; in response to acquisition of the command, controlling an actuator so that the user can be included in a FoV of a camera module, and thus changing a capturing direction of the camera module; acquiring first gesture information on the user's moving gesture through the camera module at a first time point and a second time point; at the second time point, controlling the actuator so that the FoV can be changed, on the basis of a direction determined by the first gesture information; acquiring space information corresponding to the changed FoV through the camera module; controlling the actuator so that the user can be included in a FoV of the camera module, at a third time point after the second time point; acquiring second gesture information on the user's moving gesture through the camera module after the third time point; and when all the pieces of gesture information are acquired as an input, executing the command on the basis of a designated area determined by the acquired gesture information and the acquired space information.
