Abstract
A head-mounted display (HMD) system includes a head-mounted frame that encases a portable electronic device (PED) that includes a touch-less sensor, and the PED. The frame includes: a front slot to hold the PED and maintain contact with the PED's display face; an entry via dimensioned to prevent blockage of the sensor's field of view; and a light turning element positioned to redirect the sensor's field of view through an exit via in the frame and into open space outside of the frame. The PED includes: the sensor to detect a touch-less gesture; an image display to display image content on the PED's front display face; and processing circuitry configured to change modes from handheld mode to HMD operation mode based on a determination that the PED is encased by the frame and to select the image content based on input signals received from the sensor and the mode.
