We describe a new concept of human visual perception manipulation using illumination projection. The idea is to alternate material appearance of an object using projector camera feedback and a manipulation technique of an image-based material appearance. Unlike the simple display technique, our approach can manipulate human material perception for any object using the appearance control technique in real time without scene modeling. The experimental results show the ability of manipulating both human translucent perception and gloss perception. [ABSTRACT FROM PUBLISHER]
