The same research group responsible for the Android e-ink prototype have returned with a scalable multitouch system, offering the accuracy of the iPhone on a potential scale more akin to Microsoft's Surface. Moto Labs' multitouch display uses capacitive touch, via a grid of tiny wires that recognize points of contact from any number of fingers.

The grid system has already been used in single-touch displays, but not multitouch. According to Moto Labs, the benefit is in scalability: right now their prototype is a 19-inch display, but the system could be applied to a 50-inch panel. The ITO multitouch system used by the iPhone and iPod touch is limited to roughly sub-8-inch panels.
Moto Labs also believe it's a more affordable setup than rival systems, and there's an obvious size benefit: with no need for cameras or projectors, as used by the Microsoft Surface, their multitouch display can be as thin as a standard LCD panel. In fact, the biggest problem right now is manufacture, with Moto Labs' team producing the system "by hand in our lab".
