1. A system, comprising:

  • an electronic device;

    a radar system, implemented at least partially in hardware, configured to;

    provide a radar field;

    sense reflections from an object in the radar field;

    analyze the reflections from the object in the radar field; and

    provide, based on the analysis of the reflections, radar data;

    one or more computer processors; and

    one or more computer-readable media having instructions stored thereon that, responsive to execution by the one or more computer processors, perform operations comprising;

    determining, based on a first subset of the radar data, a presence of the object within an awareness distance of the electronic device;

    responsive to determining the presence of the object within the awareness distance, providing a presence-based function of the electronic device;

    determining, while the object is within the awareness distance, a presence of another object within the awareness distance;

    responsive to determining the presence of the other object within the awareness distance, modifying the presence-based function of the electronic device;

    determining, based on a second subset of the radar data, that the object is outside the awareness distance of the electronic device; and

    responsive to determining that the object is outside the awareness distance, ceasing to provide the presence-based function.
