| Outline of Final Research Achievements |
Recently, ubiquitous display environments have been very popular. Therefore, we needed to research on human vision from the new aspects. Psychological experiments results suggest that (1) degradation in human discrimination sensitivity in High Dynamic Range (HDR) environments exists and our unique proposal demonstrates that the global tone mapping technique is quite effective for HDR-SDR (Standard Dynamic Range) conversion, (2) both chromatic perception of dichromatic observers and that of trichromatic ones have continuous distribution in color structure perception, (3a) new illusion, named “curved-surface-aftereffect (CS-AE)”, was found when viewing curved displays, (3b) subjects with a rigid perception of CS-AE can integrate visual and gravity sensory systems well, and (3c) therefore we should be very careful in applying cutting edge technologies to visual interfaces.
