Audio-visual arrangements

A data projector, a slide projector and an overhead projector will be available in the lecture theatre. The standard length for contributed papers is 15 minutes plus five minutes for discussion. A distribution box will be available to allow up to four lap-tops to be connected to the data projector before the session begins.

Nevertheless, if you are using Powerpoint, please prepare a lecture of 13 minutes or less, in order to allow for the time needed to change between lap-tops and to restart software etc.

Poster Session

The poster session will be held on Saturday afternoon, 14.00 - 17.00 on the first floor of the University Centre. The Centre is reached from Peterhouse by walking a few paces towards the river down Little St. Mary's lane; the Centre is on your right. Tea will be served in the poster session at 16.00.

Boards will be available for mounting posters from 13.00. Posters should be mounted with velcro, which will be supplied. The dimensions of poster boards are 2 x 2 metres. The boards will be numbered and these correspond to the numbers of the abstracts in this book.

Trade Exhibitors

Exhibitors at the meeting will include: Cambridge Research Systems (Visual stimulus generators), D. G. Colour (colour tests and materials), Micron Techniques (spectroradiometric instruments), and Oculus (HMC anomaloscope). The exhibitors will be found in the coffee area.
