Abstract

In this study, we examined effects of 3D cues (texture, contour and shading) on detection of a symmetry pattern in a 3D curved surface. In the experiment, we used dot patterns drawn on a front surface of a transparent cylinder and performed discrimination tasks between symmetry and random patterns. We manipulated the orientation of cylinder axes and symmetry axes. As a result, we obtained high performance regardless the orientation of cylinder axes and symmetry axes when the three 3D cues were given simultaneously or those orientations were matched. Furthermore, it was shown that shading was the most effective cue. This suggested that the detection mechanism of a symmetry pattern in 3D space involves percept of a global surface where the pattern is drawn.
