1. An electronic device comprising:
- a display;
a dielectric substrate disposed on the display;
a plurality of antennae including a plurality of transmit antennae disposed on a first side of the substrate disposed on the display and arranged and constructed to emit radio waves, and a plurality of receive antennae disposed in an array on a second side of the substrate disposed on the display to receive backscatter from the radio waves such that the transmit antennae and receive antennae are disposed on opposite surfaces of the dielectric substrate and the transmit antennae and receive antennae and the substrate are all disposed on the display;
a processor operably coupled to the plurality of antennae to utilize the received backscatter to;
detect voltage at each of the receive antennae disposed in the array on the display; and
based on which ones of the plurality of receive antennae disposed in the array at which voltage changes are detected, detect location of an object spaced from the display, size of the object, and shape of the object;
identify the object based on the size of the object and the shape of the object;
determine at least one attribute of a gesture including at least one of gesture speed, gesture shape, or gesture direction based on repeatedly detecting the location of the object;
identify the gesture based on the object identified and the at least one attribute of the gesture; and
identify a command associated with the gesture.
