That is my overriding memory of London, not just from Monday morning but from whenever a WG Chair first encountered the projectors. The problem, commonly, was one of aspect ratios, of the projector and laptop having different views of what the representation should be. Somewhere, I have a note of how long - 5 to 10 minutes - each of the sessions was late in starting. As a presenter myself, I was taught to rehearse and rehearse until it all went off pat, and that included all the technology. Yet WG Chairs would turn up at 09:00, e.g., and expect to have the 'Note Well' on display by 09:01:-( Tom Petch > Having done the usability thing back in the day, it is instructive to ask a > UNIX/Windows/Mac sysadmin how easy they find a task they do every 3-4 > months or so and then videotape them performing said task and then play > the video back to them. >
