Abstract
A portable computing device includes a three-dimensional (3D) touch screen and a core module. The 3D touch screen includes a two-dimensional (2D) touch screen section and a plurality of radio frequency (RF) radar modules. The core module is operable to determine whether the 3D touch screen is in a 3D mode or a 2D mode. When the 3D touch screen is in the 3D mode, the core module is further operable to receive one or more radar signals via one or more of the plurality of RF radar modules and interpret the one or more radar signals to produce a 3D input signal.
