We are exploring the use of visual imagery which simultaneously provid
es the content and control of web-based interactive services, We descr
ibe four unconventional web-based services we have implemented for: me
ssaging, a bulletin board, broadcast messages, and browsing through a
set of hyperlinked objects. We implement each service using a real-wor
ld metaphor which serves as the basis for the visual presentation as w
ell as the service itself; thus form and function are tightly coupled.
The use of universal imagery eliminates the need for wordy explanatio
ns and hence increases accessibility to an international audience. Dur
ing the course of development, we devised techniques to enhance the sh
ared experiences of the visitors to our sites, including automatically
generated 2D animations, These approaches can be applied to a variety
of web-sites and are also described. (C) 1997 Published by Elsevier S
