| Abstract(in English) | Illusory two-dimensional displays can be made in which a ball can be seen as either floating or crawling in a box,depending on the motion or position of its cast shadow. In this research, we assumed a light source not only over the ball, but also under the ball, in front of the ball, and on its left and right side. Thus cast shadows were created not only on the floor, but also on the ceiling, the inner wall, and the right and left wall of a box. This way, we could investigate how we connect the ball with its cast shadow when the shadow is moved in various places. We also investigated how the perception of the ball chaged when fixating on a fixation point or when tracking the motion of the ball or its cast shadow. We found that as the distance between the ball and its cast shadow became longer, the connection between them became weaker. Especially when the cast shadow was on the ceiling, the ball and its cast shadow mostly could not be connected. |
