Abstract
Described herein are systems and techniques for projecting content, periodically or continuously, onto a rear surface of a display medium from behind. The rear projected image is presented on an opposing or front surface of the display medium to a human audience for viewing. Additionally, non-visible light (e.g., IR light) is passed through the display medium to an area in front of the medium. The non-visible light is used to detect human gestures. In this manner, the rear projection arrangement avoids viewer obstruction during projection, yet detects and recognizes gestures made by the viewer in front of the display medium. In one implementation, the display medium comprises a thin sheet of transparent plastic material with arrays of curved optical features to redirect light received on the rear surface out the front surface toward the human audience.
