三次元錯視表面の動的構造変化とその知覚特性

抄録

when the adequate visual stimuli are suitably arranged partially along the surface boundary an opaque or transparent illusory surface canbe seen. Dynamical fusion and separation of illusory surface have been observed when the visual stimuli were canged continuously between two different conditions so that one illusory surface could be perceived in the first conditions and twe separated illusory surface could be perceived in the other condition. Geometrical arrangements for the fusion and the separation have been measured ; then hysteresis of the perception was recognized in the geometorical positions between the fusion and the separation of the surface. In addition, we observed these phenomena with a stationary illusory surface surrounding the dynamically changing illusory surface, then we found that the perception of the fusing and separating positions were chang.
