Chris O’Shea of Pixelsumo sent me a note letting me know he has been collecting info on mutli-touch screens as well and has a wealth of links to check out. The most impressive of which is the Perceptive Pixel screen. Check out the video to see it in action. We’ve previously covered O’Shea’s Sonicforms project.
I also recalled hearing about some big multitouch screens at CES this year, but google is not helping me. I did find a mention of a large screen from Sharp that was shown at IFA 2006. Watch this clip at about 1:37 for a short view. I can’t find any more details on it, so if someone knows more, I’d love to hear it.
And some tech details:
Accenture’s patent-pending touch sensing system has the ability to distinguish between touches from multiple simultaneous users. Additionally high-resolution cameras are leveraged to provide touch capabilities for simultaneous usage. The screen consists of a series of nine rear-projection DLP screens fastened together to display cohesive images at a clarity of 2100 x 1200 pixels/resolution. The network is managed and updated from a remote location to allow for content to be adjusted regularly.
