Abstract
Recently, as CAD systems have been spread, style design with digital mockups has been used. But the method using physical mockups is still used to evaluate products from ergonomic design. However, the conventional methods of the evaluation using a physical mockup of a product are inefficient in an upstream style design process, for it costs time and money. So, our research purpose is to develop a system for ergonomics design, which enables an ergonomics evaluation for a palmtop IT device without “real” subjects and physical mockups by integrating a digital hand with a product model and its task operation model.
