Microsoft "Microsoft and Perceptive Pixel Inc. (PPI) today announced that they have entered into a definitive agreement under which Microsoft will acquire PPI, a recognized leader in research, development and production of large-scale, multi-touch display solutions." Yes, Jeff Han is now a Microsoft employee. This demo still amazes me - from 2006. Before the iPhone. Before Android. Before the iPad. Remember that the next time you wind up in a discussion about who supposedly invented what.

RE[3]: I built one too!

Member since:

I've already discussed the issue of noise in another reply, so I'll just explain what makes capacitive touchscreens so unreliable as compared to all other touchscreen techs : their sensitivity to water. If your screen becomes humid for any reason (rain, sweat, freshly washed hands...), the device will start become unresponsive or register false positives in a matter of minutes. Since when do we build mobile devices that can't stand a few drops of one of the most widespread chemicals of planet Earth ?

And there is a reason why the tech is so expensive and sensitive to external perturbations too : it requires ridiculously complex hardware by its very nature. As if resistive touchscreens and their need for fine-tuned mechanical properties weren't complicated enough, the best which hardware engineers could come up with as a successor was a fine mesh of transparent electrodes stuck in the tiny space between a LCD and a protective plate, following the tiny capacitance difference induced by the presence or absence of a human finger milimeters away while shielding itself from its direct electromagnetic environment somehow ? Honestly, if they just wanted to come up with something bizarre enough that it would create tons of jobs in R&D and stimulate the economy, they could have stated the goal right away...
