Psycho-Physiological Evaluation by Stereoscopic Display Systems in Artifacts

Abstract

In this study, a basic examination on psycho-physiological effects by display systems of stereoscopic 3D images 3D was carried out. Time-multiplexing and spatial-multiplexing systems were focused as major 3D display systems for consumer use. Characteristic artifacts of each system were extracted, and their psychophysiological effects were evaluated. Concretely, phantom array, pseudo parallax and flicker from time-multiplexing system, and binocular-rivalry, pseudo parallax and reduction of resolution from spatial-multiplexing system were defined as characteristic artifacts and represented by simple visual stimuli for experiments. From the results of the experiments, inductions of the artifacts were confirmed, and the psycho-physiological responses of the participants were changed by the intensity or combination of the artifacts. In addition, individual difference of the artifacts in the psycho-physiological effects and the interactions, and possibilities to reduce the effects by presentation methods were suggested.
