Technologies for detecting touch events on, or hover events above, a surface of an electronic device using radar units instead of integrated capacitive touch sensing technologies, are described. An electronic device includes a display located along a first plane. The electronic further includes a first radar unit coupled to the display. The first radar unit is oriented and comprises a first field-of-view (FoV) along a portion of the first plane. The electronic device further includes a processor coupled to the first radar unit. From the first radar unit, the processor receives first data that indicates a first object detection corresponding to a first location. The processor further determines, using the first data, a touch event associated with the display.
