    processing one or more of the images to extract biometric features of the hand;

    authenticating the hand based on the extracted biometric features;

    determining a dominant user from among the users based at least on one or more biometric features extracted of the users;

    processing the sequence of the images as a hand gesture;

    determining a command indicated by the hand gesture;
