| Research Abstract |
In this research, we measured visual function and visually evoked cortical potential (VEP) and estimated for psychological scaling.
The results were as follows. 1.Measurement of visual function The accommodation response and the pupillary response varied from observation of a real object or a plane picture. The accommodation response depended on disparity, and the pupillary response compensated for one.
2.Measurement of visually evoked cortical potential (VEP) The peak appeared on the neighborhood of 190msec and 270msec after that stimulus were received. The correlation was observed between appearance of the peak of 190msec and recognition of binocular double images.
3.Psychological scaling "Stereoscopic Factor" and "Realistic Factor" were extracted. These valuation depended on degree and combination of parameter of stereopsis.
