[Kyle McDonald] had a Visioneer XP 100 portable scanner laying around, so he started trying to come up with alternative uses for it. In the video above, we can see a multitouch setup rigged together using Openframeworks in Ubuntu. As you can see in the video, there’s some considerable lag. That is due to the 250-500 ms of buffering built into the scanner. It does have nice resolution; 10k pixels wide at 60 fps, so it has to be useful for something (aside from scanning). Anyone got any ideas? He says if the field of view was wider, he’d use it on a river bed to watch fish.
