This paper reviews recent research on the perception of tangible pictures by sighted people and those who are blind or have extremely low vision. Raised-line pictures are useful for evaluating spatial cognition in congenitally blind people. The ease or difficulty of picture recognition is shown to vary with complexity, familiarity, and categorical information. Blind people are able to use pictorial displays effectively, but may benefit from instruction when complex depictions of three-dimensional objects involve foreshortening.
本文回顾了近期关于有视力者以及盲人或视力极低者对实体图片感知的研究。凸线图片对于评估先天性盲人的空间认知很有用。研究表明，图片识别的难易程度会因复杂性、熟悉程度和类别信息而有所不同。盲人能够有效地使用图片展示，但当三维物体的复杂描绘涉及透视缩短时，他们可能会从指导中受益。
