Outline of Final Research Achievements

We psychophysically analyzed human material perception. We found how gloss perception is affected by image properties of illumination, color relationships between highlight and body, spatial relationships between highlight and surface shading, and the time course of infant development. We found image cues to translucency, and a new aftereffect wherein adaptation alters the material, shape and category of objects. We found critical information about liquid material perception lies in image motion vector fields, as well as in dynamic image deformation fields. We have developed a hyperspectral two-dimensional display, and a projection mapping technique that makes a static objects appear dynamic. We found counterintuitive effects of object and hand colors on object temperature judgments, and a computational principle of integration of audio-visual material information.
