1. A smart device associated with a radar field, the smart device comprising:

  • a non-line-of-sight gesture-recognition system configured to;

    provide the radar field, the radar field including a direct radar field and a reflected radar field, the reflected radar field provided in one or more volumes in a room to which direct line-of-sight from the non-line-of-sight gesture-recognition system is not available;

    sense radar reflections from an interaction that is within the reflected radar field, the radar reflections sensed by receiving the radar reflections from a surface of the room and at an antenna of the non-line-of-sight gesture-recognition system;

    recognize, based on the radar reflections from the interaction that is within the reflected radar field, a gesture; and

    determine that the gesture is associated with a non-line-of-sight smart device; and

    a transceiver or network interface configured to pass the gesture from the smart device associated with the radar field to the non-line-of-sight smart device in a format usable by the non-line-of-site smart device to recognize the gesture and effective to enable the gesture to control the non-line-of-sight smart device or establish communication with the non-line-of-sight smart device.
