Processes of Visual Perception and the Implications for Optimisation of Displays

摘要

This report has been written after several seminars within RSRE had highlighted a number of disturbing facts. Firstly, there is very little dialogue between the designers of displays and the vision researchers. Secondly, although a great deal of information exists on the performance of the eye, it is often obscure and the practical implications are not clear. Thirdly, for a display engineer who is not necessarily interested in the fine detail if the visual mechanisms, sources of practical data covering the whole subject of human vision are scarce. A brief description of the physical properties of the eye is given together with an account of the various methods of measuring observer performance. The diagrams are provided as a means of indicating general trends with a minimum of descriptive narrative. A broad bibliography is included so that those interested in specific topics can follow them up. (Author)
