Evaluating layout discrimination capabilities of continuous and discrete automultiscopic displays

Abstract

[Abstract]: Continuous automultiscopic displays represent a promising technology, able to drive users into really involving and compelling experiences. In this paper, we report on perceptual experiments carried out to evaluate the depth discrimination capabilities of this technology with respect to two-view (stereo) and discrete multi-view designs. The evaluation employed a large scale multi-projector 3D display offering continuous horizontal parallax in a room size workspace. Two tests were considered in the context of depth oblivious rendering technique: a layout discrimination task, and a path tracing task. Our results confirm that continuous multiview technology is able to elicit depth cues more efficiently with respect to standard stereo system, providing clear advantages in typical analysis tasks like network structures understanding. Furthermore, our results indicate that depth perception capabilities are closely related to the number of views provided by multiview systems
