Abstract
The concept of Augmented Prototyping combines Rapid Prototyping techniques to obtain 3D physical objects (e.g. Stereolithography, CNC milling), with Augmented Reality systems. In this article, a comparison is made between the performance of augmented and virtual prototyping. This is done by a design review experiment of a handheld voice recorder. Two prototypes were developed, 1).a screen prototype based on Macromedia Director, 2) an augmented version that employed a video projector to project the screen on a wooden mock-up. In total, 9 subjects participated. Although not statistically sound, this evaluation indicated that the Augmented Prototyping condition yields more feedback, involving aspects of both cognitive and physical ergonomics.
