Proximity detection for touch input devices

An electronic device comprising:

• a housing;
• a processor;
• a non-transitory computer-readable memory device in electronic communication with the processor;
• a capacitive touch-sensing interface disposed within the housing, the capacitive touch-sensing interface having a perimeter, the perimeter having a length and a width, the capacitive touch-sensing interface being in electronic communication with the processor;
• and
• a plurality of capacitive object sensors, each of the plurality of capacitive object sensors being disposed within the housing, in electronic communication with the processor, and disposed laterally external to at least one of:
• the length of the perimeter of the capacitive touch-sensing interface;
• and
• the width of the perimeter of the capacitive touch-sensing interface.

An electronic device comprising:

• a housing comprising a housing external perimeter;
• a touch screen interface disposed within the housing and comprising one or more trace layers;
• and
• a first capacitive object sensor positioned laterally adjacent a perimeter edge of the one or more trace layers and located within the housing external perimeter, the first capacitive object sensor comprising:
• a first conductor positioned on a first side of an insulator layer;
• and
• a second conductor positioned on a second side of the insulator layer.
