Allow a minimum of 20 seconds for each slide or overhead to be up on the screen. They should not be crammed with detail. That's all you'll have time for. Because the configurations of equipment vary so much, there is absolutely no guarantee that your presentation will work with the particular LCD projector assigned to your meeting room. You may bring your own LCD and set it up at the break immediately before your talk is scheduled.
Experience shows that LCD to computer incompatibility can be a real problem.
We will try to have people around to help troubleshoot any difficulties that emerge during this dry run, but sessions themselves cannot be delayed in order to fix problems that arise therein. Please remember that session chairs cannot delay the schedule if an LCD fails or proves incompatible during a session. In planning your presentation, follow the tips given above for slides and overheads. We will have concurrent sessions Tuesday and Wednesday afternoon. A single overlong presentation will throw off the entire schedule and the option for people to jump between sessions.
