Cowan Associate Professor of Computer Science and Psychology Colour adds greatly to the richness of all aspects of visual experience. At the same time it is surprisingly difficult to use effectively, whether its purpose is aesthetic or informational. The increasing use of colour on computer displays makes it imperative that techniques for using colour, long known to designers and artists, be embodied in graphical algorithms for use by the computer industry. To do so it is necessary to study the interaction of the human visual system with the display properties of computer output media. This lecture provides an introduction to human processing of information displayed using colour, with an emphasis on those aspects that are important for graphical computer interfaces and some of the novel problems that arise when the display surface is shared by the output of several application programs. William Cowan has been an associate professor of computer science and psychology since 1988 and is director of the Computer Graphics Laboratory. He obtained a a BSc in physics from the University of Waterloo and a PhD in statistical physics from McGill University, then worked at the National Research Council of Canada where he learned colour psychophysics from the late Gunter Wyszecki. His research interests encompass many aspects of the transfer of information from a computer to its human user, particularly those in which information density is great and where temporal and multi-processing (by human or computer) factors are important. Everyone is welcome to attend the ICR evening lecture series. Each lecture addresses an area of current research at the University of Waterloo related to the use of computers. The series is designed for a broad audience, including non-specialists interested in gaining more insight into recent advancements in the field of computing and the potential impact those advancements have on everyday life. Coffee and cookies will be served after the lecture. Guest parking is available in the University's ``B'' Parking Lot (entrance off Phillip Street).
