In 1979, James Gibson completed his third and final book “The Ecological Approach to Visual Perception”. That book can be seen as the synthesis of the many radical ideas he proposed over the previous 30 years – the concept of information and its sufficiency, the necessary link between perception and action, the need to see perception in relation to an animal's particular ecological niche and the meanings (affordances) offered by the visual world. One of the fundamental concepts that lies beyond all of Gibson's thinking is that of optic flow: the constantly changing patterns of light that reach our eyes and the information it provides. My purpose in writing this paper has been to evaluate the legacy of Gibson's conceptual ideas and to consider how his ideas have influenced and changed the way we study perception.

1979 年，詹姆斯·吉布森完成了他的第三本书，也是最后一本书《视觉感知的生态方法》。这本书可以被看作是他在过去 30 年里提出的许多激进思想的综合——信息的概念及其充分性、感知和行动之间的必要联系、需要看到感知与动物特定的生态位的关系。以及视觉世界提供的意义（可供性）。超越吉布森所有思想的基本概念之一是光流：到达我们眼睛的光的不断变化的模式及其提供的信息。我撰写本文的目的是评估吉布森概念思想的遗产，并考虑他的思想如何影响和改变我们研究感知的方式。
