Abstract

Spatial Augmented Reality allows the appearance of physical objects to be transformed using projected light. Computer controlled light projection systems have become readily available and cost effective for both commercial and personal use. This chapter explores how large Spatial Augmented Reality systems can be applied to enhanced design mock-ups. Unlike traditional appearance altering techniques such as paints and inks, computer controlled projected light can change the color of a prototype at the touch of a button allowing many different appearances to be evaluated. We present the customized physical-virtual tools we have developed such as our hand held virtual spray painting tool that allows designers to create many customized appearances using only projected light. Finally, we also discuss design parameters of building dedicated projection environments including room layout, hardware selection and interaction considerations.
