Effective designs rarely emerge from good structural design or aesthetics alone. It is more often the result of the end product's overall design integrity. Added to this, design is inherently an interdisciplinary collaborative activity. With this in mind, today's tools are not powerful enough to design complex physical environments, such as command control centers or hospital operating theaters. In this demo a process for designing small appliances using spatial augmented reality is presented. The goal of this demo is to show how using a SAR environment can improve the design process.
