The perception of curved surface depending on viewing distance
Hatsuho Aoshima, Shunji Sato (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) We investigated the perceptual difference of cylindrically curved surfaces of random-dot-stereograms (RDS) and real objects. The ‘real’ objects used in this study are transparent sheet filled with with random-dots, and the objects are illuminated by the back light emitted from a LED monitor. In experiments of this study, human subjects observed cylinders of five kinds of radii with three different viewing distances. Experimental results indicate that the perceptual difference of depth between RDSs and real objects depends on the viewing distance and the visual angle of objects. Moreover, we find a mathematically simple description of perceived surface, viewing distance and visual angle of objects. As an application of virtual reality, we propose a method computing horizontal difference of RDSs which could be perceived as the same surfaces of real objects.
