Abstract: We propose a virtual remote control interface called the “Everywhere Switch” as an alternative to multiple remote controllers for many computerized home appliances. The interface consists of a group of virtual touch buttons projected near the user from a projector affixed to a pan-tilt mount just below the living-room ceiling. Methods to implement our system, including methods to search for a place to project the virtual touch buttons, to extract finger and shadow regions on the virtual button area and determine their ratio, and to detect touch operations, are described. We evaluated the precisions of the foreground extraction (finger or its shadow) and the segmentation of the finger and its shadow under three different brightness conditions (dim, semi-bright, and bright). The foreground extraction showed an F value of more than 0.97, and the finger/shadow segmentation showed an F value of about 0.8 in all tested brightness conditions.
