Abstract
A user identification based control system includes a time of flight ranging sensor configured to sense a distance to a person, where the time of flight ranging sensor is positioned so the sensed distance is a function of a height of the person. Processing circuitry is coupled to the time of flight ranging sensor and configured to identify the person based upon sensed distance and to generate control signals to control peripheral components based upon the identity of the person. The time of flight ranging sensor may also be used to sense speed of the person for identification purposes. In general, the time of flight ranging sensor is positioned a known height over a surface on which the person is present, such as in the doorway or on a ceiling of a room.
