ICR Evening Lecture Series

Dr. William B. Cowan
Associate Professor of Computer Science & Psychology

Date: Monday, November 27, 1989
Time: 8:00 p.m.
Place: DC 1302

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 computer 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 BSc in physics from the University of Waterloo, then worked
at the National Research Council of Canada where he learned colour psycho-
physics 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.
