Factors Which Influence How a Person Perceives Objects Represented in a Two-dimensional Picture

The work referenced was a presentation at the Computers in the Curriculum project conference held on 7th-9th Nov 1983 at Avery Hill College, Eltham, London, as reported by Mark deWolf in the project newsletter in July 1984:

"The last speaker of the conference was Dr Steve Scrivener who is Head of Graphics at Leicester Polytechnic's Human-Computer Interface Research Unit. His talk proved to be very stimulating indeed, as he used slides of selected works of art to illustrate his points on the factors which influence how a person perceives objects represented in a two-dimensional picture. It was noted that many programmers already follow those principles of perceptual psychology which he outlined (continuation, illusions of depth, colour use, etc) but they do it instinctively in most cases, and it was generally agreed that having these principles made clear in this way would be extremely useful."
