1. A computer-implemented method comprising:

  • providing, through a radar-based gesture-recognition system, a radar field;

    sensing, through the radar-based gesture-recognition system, one or more initial interactions by an actor in the radar field, the actor being one of a particular human finger, hand, or arm;

    determining, based on the one or more initial interactions in the radar field, an identifying factor, the identifying factor including a height, weight, skeletal structure, facial shape, or hair of the actor;

    associating the identifying factor with an identity, the identity identifying the actor; and

    storing the identity of the actor with the identifying factor for the actor, the identifying factor enabling identification of an unknown actor through comparison of a second identifying factor with the identifying factor, the second identifying factor sensed by the radar-based gesture-recognition system or another radar-based gesture-recognition system, the identifying factor and the second identifying factor being equivalent features of the actor and the unknown actor.
