The Guelph‐Waterloo‐McMaster interactive video‐link

The development and operation of the Guelph‐Waterloo‐McMaster interactive Video‐Link is described. The link was built to service primarily senior and graduate courses in chemistry and physics so particular attention has been paid to the transmission and legibility of graphic material and the layout of the classrooms. In addition the system has been designed to operate without technical attendance using microprocessor control to simplify the lecturer’s control functions.
