An input screen is carried by the housing and comprises a plurality of spaced transceivers positioned at the input screen and connected to the processor and each configured to transmit a millimeter wave RF signal and receive reflected signals from an object positioned close to the input screen. The processor is configured to determine the location of the object relative to the input screen based on the reflected signals received at each transceiver.
