Abstract Virtual reality systems have been developed over the last few years to provide real time, immersive, three dimensional rendering. There have been efforts to utilize virtual reality and other similar approaches for design (Jones, 1996); however, limited information has been placed in the open literature describing the development of systems used specifically for the design of complex products, like naval vessels. As added motivation, features have been widely accepted as a useful paradigm for design purposes, but experience with feature based design in a virtual reality environment has also been limited. With these issues in mind, this paper was written to describe an ongoing research project that focuses on the demonstration of feature based design in a virtual reality environment for submarine design. To support this development, progress to date using the GROTTO, a CAVE like system, at the Naval Research Laboratory is reported. A “spin-off” of the research to web based collaboration is reported, an outline of projected system architecture is provided, and conclusions are drawn regarding the development of the virtual system.

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.
