Personally supported dynamic random dot stereogram by measuring binocular parallax

Abstract

We present a novel approach to the use of gaze tracking as a means of supporting the experience of a Random Dot Stereogram (RDS). RDS is a method for producing an apparently noisy image that actually contains a stereoscopic scene, which becomes visible under a certain parallax of the eyes [1]. Although adjustment of eye convergence is required for RDS, many people have difficulty in making this adjustment. We implement a system by which most can stably experience stereoscopic images from RDSs. We confirmed that the times users took to find stereoscopic scenes in dynamic RDSs (d-RDS) were significantly decreased compared with presenting d-RDSs with fixed parallax. We also demonstrate this system as a means of secure information display when users input a password.
