8.5 Perception

Based on sensorimotor models, the present work showed how visual perception might emerge:

These experiments show that perception of space and shape can be explained by the sensorimotor approach. Instead of using a pure sensory representation, all is reduced to the simulation of motor commands and their sensory consequences.

In the mobile-robot study, depth perception was based on computing the time-to-contact; in the robot-arm study, depth perception was based on associating an arm posture. This difference implies that for unlike tasks different spatial representations exist, for example, a far field for locomotion and a near field for grasping (Mallot et al., 1992).
