Only a few weeks after attendees at the annual developer conference of Finland's MultiTouch Ltd got a first look at the company's latest MultiTaction monster, it's gone up for pre-order. Currently a working prototype, the new 84-inch unit is claimed to be the world's first fully integrated, 4K resolution interactive display.

MultiTouch Ltd expects to start producing the new MT840UHD model in mid 2014, and says that it will have the same fast response times as the current 42-, 46-, and 55-inch MultiTaction Cell Displays. A single 84-inch 4K multi-touch module can be set up as a table, or as a movable interactive vertical display courtesy of the included wheeled floor mount. Multiple units can also be stacked to create huge multi-touch walls.

The final production specs are still to be confirmed, but dimensions of 75.2 x 43.3 x 7.9 in (191 x 110 x 20 cm) and a module weight of 287 lb (130 kg) have been tentatively released. The Quad HD MultiTaction display could include a touch surface fronted by 5 mm of tempered glass, a system of 72 cameras, HDMI or DVI 4K input ports, and benefit from 500-nit brightness. It's unlikely to sport an ultra-thin-bezel design, but will feature the company's Computer Vision Through Screen technology, which is capable of tracking unlimited simultaneous touch points from hands, pens, special markers and real-life objects.

Custom interactive applications can be created using MultiTouch's all-new Cornerstone 2 SDK, which is reported to perform 50 percent better than previous versions of the software.
