A new large-format multi-touch technology launched today by DISPLAX, a developer of interactive technologies, will transform any non-conductive flat or curved surface into a multitouch screen. The DISPLAX Multitouch Technology, believed to be the first of its kind, has been developed based on a transparent thinner-than-paper polymer film. When applied to glass, plastic or wood, the surface becomes interactive.
It can be applied to flat or curved, opaque as well as transparent surfaces up to three metres across the diagonal. It is hyper sensitive, allowing users to interact with an enabled surface not just by touching it but, for the first time, by blowing on it, opening up new possibilities for future applications. Currently, the technology can detect up to 16 fingers on a 50-inch screen. The number of fingers detected is expected to increase as development progresses.
Based on patent-pending projected capacitive technology, DISPLAX Multitouch Technology uses a controller that works by processing multiple input signals it receives from a grid of nanowires embedded in the film attached to the enabled surface. Each time a finger is placed on the screen or a user blows on the surface, a small electrical disturbance is caused. The micro-processor controller analyses this data and decodes the location of each input on that grid to track the finger and air-flow movements. The DISPLAX Multitouch technology controller combined with a projected capacitive nanowired film is a lightweight and highly scalable solution, ranging from seven inches (18 centimetres) to three metres across the diagonal thus opening up a wide range of commercial applications suitable for indoor or outdoor displays.
The DISPLAX Multitouch Technology will begin shipping in July 2010. The prices will be very competitive and depend on size.
Toronto Nuit Blanche was a blast. For those of you who don’t know:
This year the local Toronto Artist and Ryerson Image Arts Student, Mike Lawrie and I have entered a Independent project — Multitorch — under the Ryerson University/Faculty of Communications And Design’s Lightup the Night. The project involves a 23’x13′ (26′ diagonal) projection weighing in at 4096×2048 pixels driven by a multitouch engine. Up to 10 Infrared LED torches are handed out to the audience and the system will allow them to interact with the projection in front of them. As far as we know this is the largest (and highest resolution) multitouch screen deployed to date. The project uses CCV (Community Core Vision) tool for tracking, OSC (Open Sound Control) for communication and a 4500 line custom java visual engine. Here is a short 5:00 minute Timelapse video.

Yep you heard right….freaking lasers…..yummy. These guys have managed to turn a rear-projection TV into a multitouch surface using IR lasers. Absolutely fantastic as it (using lasers) makes the whole design a lot simpler and gets rid of the the tracking problems associated with regular IR LED based tables and ambient IR light. Although the original laser idea comes from arbi.trario.us gang, stuffing everything inside a 16″ deep tv is a nice touch :-).
Below is a good rundown of the pros and cons of this setup vs. FTIR:
Their blog page outlines everything…..and I mean everything.
