Spatial augmented reality for product appearance design evaluation

Augmented reality based on projection, called "Spatial Augmented Reality (SAR)", is a new technology that can produce inversive contents by overlapping virtuality and real-world environment. It has been paid attention as the next generation digital contents in media art and human computer interaction (HCI). In this paper, we present a new methodology to evaluate the product appearance design more intuitively by means of SAR technique. The proposed method first projects the high-quality rendered image considering the optical property of materials onto the mockup of a product. We also conduct a projector-camera calibration to compensate a color distortion according to a projector, a projection surl'ace and environment lighting. The design evaluation methodology we propose offers more flexible and intuitive evaluation environment to a designer and user (evaluator) than previous methods that are performed via a digital display. At the end of this research, we have conducted a case study for designing and evaluating appearance design of an automobile. (C) 2015 Society of CAD/CAM Engineers. Production and hosting by Elsevier.
