Windows 8 Hits the Really Big Screen (Video)

Microsoft showed Windows 8 running on lots of different hardware at its event in Barcelona, but the clear showstopper was seeing it in action on an 82-inch touchscreen.

The technology is from Jeff Han’s Perceptive Pixel. Han is a pioneer in multitouch and is the guy behind the screen you see all the time on CNN.

After the Windows 8 event, AllThingsD got to get up close and personal with the giant screen. Here’s the screen in action, in a video interview with Microsoft VP Mike Angiulo:

Update: Han points out that, in addition to its size, Perceptive Pixel’s technology has other benefits. First, it uses the same kind of technology as that in phones, meaning the device is much more responsive than the typical computer touch screen. Also, it can support dozens of touch points at once, unlike most technologies that can process a few fingers at most. Finally, like some laptops using technology from N-Trig, it works with pen and touch.

“Our Walls are the only large-scale touch displays that works via the same type of sensing technology (projected capacitive) as that which is used ubiquitously in phones and slates,” Han said in an e-mail interview.
