Abstract
A multi-modal sensing surface comprises two overlaid arrays: a capacitive sensing electrode array and an array of RF antennas. A first sensing module is coupled to the capacitive sensing electrode array and is configured to detect both an increase and a decrease of capacitance between electrodes in the array. A second sensing module is coupled to the array of RF antennas and is configured to selectively tune and detune one or more of the RF antennas in the array of RF antennas.
