Abstract : The goal of this project is to examine the consequences of observer motion for visual function. The research has focussed on two issues: One issue is how a grossly time-varying retinal input (because of eye, head, and body notion) results in the perception of a continuous and directionally stable visual world. A second issue concerns how the information in successive views is related, and the nature of the visual information retained from previous views. Understanding these processes is important for a wide variety of visuo-motor tasks. Progress has been made on the following projects: (1) The role of the visual scene and eye position signals in visual stability. (2) The role of attention in integrating across saccades. (3) Reference frames for spatial memory. (4) Hand-eye coordination during complex tasks. (5) Detectability of changes during saccades. (6) Short term visual memory of complex scenes.
