about this item
First published in 1991, this book is about applications and issues relating to the visual environment. The content pertains to the understanding of human behaviour in the environment by recording behaviour and actions or by direct interaction with people. The author examines research and planning methods that primarily stress the visual features of the physical environment. Traditionally, environmental research has relied on verbal descriptions and perceptions of the physical environment, virtually ignoring the visual component and the potential application of the social sciences for gathering this data. Various strategies that can expand the visual information base have been explored here: diagramming, photo-interviewing, photo-sorting, mapping, notation, simulation, videotaping, and CADD.
