This idea believe it or not came to me in a dream! (boring dreams eh?)
I have ‘built’ a home made interactive, tilt / pressure sensitive screen. All I used was my normal Wacom tablet (Intuos 3) and the mini projector borrowed from uni. It is extremely simple and crude. I strapped the projector to my tripod with cello-tape and mounted it above my Wacom tablet which was on the floor. I used a dumb bell to counter the weight of the projector on the tripod.
Wacom have their own screen tablet with their Cintiq range, however these are very expensive. This is in essence a cheap version of that product without any dissecting of valuable equipment.
Although this is a fairly interesting solution, there is a slight lag between the tablet and the screen. The biggest draw back though is that because the surface of the tablet is so smooth to avoid damage to the pen, you get quite severe glare from the projector above, a problem which would not be an issue in Wacom’s own Cintiq tablet.
I have created a video of the setup and a demo of me using the tablet:
InteractiveScreenDemo_LoH264.mov (H264, 360 x 288px, 12mb)
The end of the video shows a short clip of my anaglyph animation running on the wacom screen. A possible idea for my final project would be some sort of an interactive anaglyph programme running on this set up.
I have found a similar project to this. Some nutta has built a Wacom tablet screen by taking apart a tablet and a LCD screen and combining them together. This would probably work much better than my version, however taking apart all that equipment can be risky and expensive, my way avoids any of that risk.
