UK-based Engage Production has just stacked 24 MultiTaction Cell displays in the new "Executive Brand Suite" of an un-named City of London client to create the world's largest multi-touch interactive wall. Measuring some 9.9 x 3 m (32.48 x 9.84 ft), including the base, the monster installation's separate screens function as one huge touch display, capable of tracking and registering an unlimited number of simultaneous touch points.

The 55-inch MultiTaction Cell displays that make up the multi-touch interactive wall are manufactured by Finland's MultiTouch Ltd, creators of the Twitter Wall that impressed at CES 2011. This latest gigantic wall of touch forms part of a fully integrated and unique communications facility developed to showcase consumer changes resulting from advances in technology.

As you can see in the following demonstration video, all of the display cell modules used in the creation work as one to register and track an unlimited number of user hands, real world objects, optical markers, and IR pens at a gesture tracking rate of 200 frames per second. Users can also interact wirelessly with the installation using tablets.

In related news, MultiTouch Ltd has also announced the development of a new ultra thin bezel (UTB) MultiTaction Cell display. The bezel at the bottom and left of the new 55-inch unit is just 1.9 mm, and the right and top is 3.8 mm, a significant reduction on the stackable cells used for the monster wall in London (16 mm for the bottom and sides, 17 mm at the top).

The company says that the dramatic size reduction has been made possible by its patented optical imaging technology Computer Vision Through Screen, which integrates touch sensors into the LCD backlight modules. The system boasts the same fast tracking and unlimited simultaneous touch point capabilities as existing Cells, and is also network-enabled.

The new UTB Cell will be made available from the end of this month, with details of pricing available on request. In the meantime, here's a video showing six stacked UTB Cells in action.
