Talking with pictures: exploring the possibilities of iconic communication
As multimedia computing becomes the order of the day, so there is a greater need to understand and to come to terms with the problems of visual presentation. This paper deals with iconic languages as a means of communicating ideas and concepts without words. Two example systems, developed respectively at the universities of Exeter and Brighton, are described. Both embody basic principles of the iconic communication which,, though not unique to learning technology, is forming an increasingly important part of user-interfaces, including those in the area computer-assisted learning.
