Abstract
A touchless interactive display system includes a display with a display area bounding the display. A reflective surface is located along an edge of the display. One optical sensor opposes and faces the reflective surface so that the optical sensor has a primary, non-reflected field of view and a secondary, reflected field of view that is reflected back from the reflective surface. The primary field of view covers a first portion of the display area that is less than the whole display area, and the reflected field of view covers a second portion of the display area, such that the first and second portions of the display area cover the entire display area. The optical sensor and a processor are operable to detect an object placed within at least one of its first and second fields of view without having the object touch the display.
