Abstract
Stereoscopic head mounted display (HMD) are now widely spread for ubiquitous virtual reality in the world. But visual functions for stereoscopic HMDs have not studied much yet. Especially, lens accommodation for stereoscopic HMDs have not measured yet, because the eye balls are very close to the HMDs. To investigate the effects of stereoscopic images on human vision, we measured lens accommodation in subjects as they watched 3-dimensional (3D) images on a head mounted display (HMD). Lens accommodation was measured for 40sec as subjects gazed at 3D images on HMDs. In this report we give the results of measurements of lens accommodation when subjects gazed at Power 3D^<TM>, Cross3D^<TM>, and Pseudo 3D with natural binocular vision. We carried out the experiments on lens accommodation to the stereoscopic vision on HMDs. Actual accommodation for stereoscopic view on HMDs were confirmed. Stereoscopic since HMDs should be promising device for ubiquitous virtual reality, further research including 3D image sickness would be expected.
