Prototype Apparatus: A Document Camera
Was sitting in my ITB272 lecture on Friday night (around 8PM - the time of week when one's mind tends to wander), and my eyes were drawn to the [rarely used] document camera on the lecturer's desk.
On closer observation at the rear outputs, I noticed not only VGA and RCA, but also a USB output - in theory, making its connection to a PC nearly identical to a web-cam.
Not only that, but the camera is already mounted such that it provides the perfect viewing angle, and lighting is provided either side to eliminate any unnecessary contrasts in the image.
If I could only convince someone on the QUT A/V team to let me have a play with one and the Director Xtra, we'd have a winner.
When it comes to moving the 'Lego man' around under the camera, I'd probably just tape together three or more transparencies and blu-tac him on to the transparency - allowing him to be manipulated without any hands getting under the camera.
It's a tantalising possibility.

Hi Gordon,
I was just reading about the Legoman and the transperancies, I thought we were using a magnet of some description?No rush on replying if at all, I was just curious and I wanted to stay in the loop :)
Magnets would be viable only on thin, opaque surfaces (a thin tabletop, for example).
When the Lego man sits on the surface of the document camera, there's nowhere for a magnet *beneath* the plate to go (as opposed to underneath the Lego man but above the plate).
