Change Blindness Phenomena for Stereoscopic Projection Systems
In visual perception, change blindness describes the phenomenon that
persons viewing a visual scene may apparently fail to detect
significant changes in that scene. These phenomena have been observed
in both computer generated imagery and real-world scenes. Several
studies have demonstrated that change blindness effects occur
primarily during visual disruptions such as blinks or saccadic eye
movements. However, until now the influence of stereoscopic vision on
change blindness has not been studied thoroughly in the context of
visual perception research.
In this paper we introduce change blindness techniques for
stereoscopic projection systems, providing the ability to
substantially modify a virtual scene in a manner that is difficult for
observers to perceive. We evaluate techniques for passive and active
stereoscopic viewing and compare the results to those of monoscopic
viewing conditions. For stereoscopic viewing conditions, we find that
change blindness phenomena can be applied with a larger magnitude
as compared to monoscopic viewing of a scene.
We have also evaluated the potential of the presented techniques for
allowing abrupt, and yet significant, changes of a stereoscopically displayed
virtual reality environment.
