Perceptual completion at the blind spot
I am conducting psychophysical study in order to reveal spatio-temporal properties and mechanism of perceptual completion at the blind spot. Especially, I have examined anisotropy of perceptual completion at the blind spot.
Visual spatial localization.
Currently I am examining the role of visual attention and saccade in spatial localization. Moreoever, I am interested in the way intact humans combine information from intrinsic (egocentric) and extrinsic (exocentric, allocentric, or landmark-based) coordinate systems to locate an object in space.
Monocular region (Unpaired features in one eye's view), Occlusion, Phantom stereopsis
Phantom stereopsis is an interesting depth perception experienced despite having no disparity cue. Monocular region generated by occlusion is one of the most important depth cues in phantom stereopsis. My current interest focuses on examining whether both phantom stereopsis and disparity-based stereopsis are subserved by common mechanism.
Rapid visual processing for perceptual transparency and stereopsis
My research interest is rapid visual processing that underlies depth perception. Specifically, I am studying perceptual transparency and stereopsis using visual-search and segregation tasks for human adult observers.
Velocity perception, Pursuit eye movement, Interaction between visual and motor system
Currently I have examined links between eye movements and visual perception. Specifically, I focused on effects of smooth pursuit eye movement on velocity perception. Results in my studies showed that anisotropy of velocity perception exsists during pursuit eye movement.
