Information Highlighting by Color Dependent Depth Perception with Chromo-Stereoscopy

by Bernd Wallisch, Wolfgang Meyer, Armin Kanitsar, Eduard Gröller

Project Duration: 2002 - 2003

Abstract

Due to characteristics of the human visual system different colors induce different depth perception. This optical phenomenon is called chromo-stereoscopy and has already been used for 3D data to enhance a third spatial dimension. We propose to use chromo-stereoscopy for 2D abstract data. Color coding introduces a depth cue which encodes relevance with chromo-stereoscopy. The focus information literally “stands out” as compared to the context information. We applied this technique to two-dimensional graphs and multi-layer representations and present related software prototypes.

Applications

NOTE: Special glasses are necessary to see the chromo-stereoscopic effect, e.g. ChromaDepth glasses from Chromatek, which can be purchased at American Paper Optics.
