摘要： 根据人类视觉运动中小孔问题(Aperture Problem)的观点,如果通过小孔观察一个运动的光栅,那么人类视觉系统能够检测的唯一运动只有光栅的法向运动分量。本文设计了一系列不同形状的窗口,研究窗口内视觉系统的局域运动知觉。研究结果表明,窗口内视觉系统的局域运动知觉,包括主观运动方向和速度大小,取决于窗口的形状及光栅的朝向。传统的小孔问题的观点显然是片面的。

Abstract: According to the Aperture Problem in human motion perception,when a moving grating is viewed by the subject through a small ap-erture, the only motion that could be perceived by the human visual sys-tem is the motion component orthogonal to the bars of the grating. In this paper we designed a family of windows with diffrent shapesto deal with human local motion perception. The results reveal that hu-man local motion perception, including sujective motion direction andspeed, depends on the shapes of the windows and some constraints onorientations of the grating. It is quite evident that the viewpoint of thetraditional Aperture Problem is one-sided.
