Abstract

Contradiction between convergence and accommodation of our eyes often causes eyestrain and sickness of the viewer in the conventional stereoscopic display systems. Though there exist several methods to solve this problem, they are expensive and are not expected to be commercially available in a near future. The authors propose a novel system that realizes electronic motion images without VR sickness, consisting of cylindrical lenses and electronic image displays with high frequency striped patterns. When we see images with high frequency patterns through cylindrical lenses, we perceive change of blur and focal depth in proportion to the inclination angle of high frequency stripes. Thus this system can control accommodation status of our eyes continuously with inexpensive devices. As for natural scenes, this system uses a filter that blurs high frequency components contained in the scenes except for those needed to lead desired accommodation of our eyes. Thus this system can also induce proper accommodation of our eyes for most natural scenes including various high frequency components.
