The New York Times reports today [http://bits.blogs.nytimes.com/2012/05/16/in-tv-race-microsoft-has-lead-forrester-says] that television is emerging as a crucial strategic platform, "every bit as intense as... mobile." Apple, Google, and Microsoft (and others? Amazon? Facebook?) will vie for dominance.
I argue that making all involved surfaces -- the large TV, the smaller phone and tablet -- interactive, with multi-touch, will become essential ground for television as platform. As the platforms fully open for development, with App stores, things will get interesting.
ZeroTouch is the highest performance, most cost effective way to make the TV surface interactive. When production of the technology is scaled, costs should run in the hundreds of dollars for very large screens. The ACM CHI Austin ZeroTouch demo showed how responsive ZeroTouch sensing is, at television scale.
