Outline of Final Research Achievements

We measured eye movements and accommodation of the crystalline lens during gazing at an occlusion region. We analyzed a relationship between these signals, and proposed a model of visual information processing. Feasibility of image controlling in displaying 3D image was examined. We developed a system which displayed the different focus image according to gaze points. Using an optical see-through HMD, we measured eye movements and refractive index of the lens changing a gaze target between a real object and an image on HMD. Changing displaying positions of an image was also examined. Using a real object, we measured eye movements and refractive index simultaneously, and designed a model of gaze positions, vergence, and accommodation. Under a condition of a set of colors which are perceived as equiluminance instead of non-equiluminance patterns, we experimented on the perception of an occlusion. We obtained results which suggested this condition is similar to non-equiluminance case.
