3Live Shop by B-Reel is exactly what its name implies, a live online shop that works as a complementary service for the customers of the telecom operator 3, where they can interact with a real salesperson. You could call it a video call with a twist. The twist being a customized multi-touch experience for the sales person.
Reality Touchscreen at the University of Groningen is a DIY project made using 6 cameras and 1000 infra red LEDs. It can detect over 100 simultaneous touches.
“The cameras, illuminators and projectors are all placed behind the screen. Due to the diffuse layer on the front side of the screen, the cameras cannot see clearly through the screen, however whenever someone touches the screen, enough of the infrared light is reflected back to see the tip of the finger. The difference is very small (on a scale of 0-255 the difference is only 2 or 3), but still big enough to be seen by the computers that analyse the images from the cameras.”
Continuing their multi-touch research, IDEO have been working on turning an off-the-shelf rear projection TV into a multi-touch display. This screen has the best width-to-depth ratio of any multitouch system (67″ diagonal viewing area and only 16″ deep).
It’s the first example of hacking a multi-touch system into an off-the-shelf television and the system they settled on uses very few additional components so could potentially be applied to any rear-projection set.
It has multiple touch enabled surfaces including four 42” HD dual touch screens, one 46” HD multitouch screen and a 108” multitouch table. The software is a mix of Windows 7, OS X and Linux but the table runs PyMT. The walls are digitally augmented whiteboards which capture anything written anywhere. This is a functioning meeting room as well as a research platform for novel UI and UX. The room will officially open it’s door in Jan 2010.
