According to one or more aspects, a gesture performed by a user may be detected. An identity of the user may be determined based on sensor input captured substantially contemporaneously with the detected gesture. Then, it may be determined, based on the identity of the user, that the detected gesture corresponds to at least one command of a plurality of commands. Subsequently, the at least one command may be executed. In some arrangements, the gesture may correspond to a first command when performed by a first user, and the same gesture may correspond to a second command different from the first command when performed by a second user different from the first user. ## Claims ### Claim 1 A method, comprising: detecting a first gesture performed by a first user;
