Locomotion and Manipulation (Gibson, 1979, Chapter 13)

Gibson turns his attention now to two major forms of behaviour, locomotion and manipulation, and discusses the optical basis for the control of these action. He considers the visual information available in these tasks, and how these can be used to control the behaviours, without appeal to a central controller (such as the brain). In this chapter Gibson proposes that these and other behaviour are all 'regular without being regulated' (pg. 215) and the question is, 'how can this be'? While he doesn't fully answer this question, he introduces the key optic flow features we will need for these two behaviours.
