Touch Screens that Curve, Bend, and Even Touch Back• http://www.technologyreview.com, By Tom Simonite
One of the most striking ideas on show was PaperTab, an early prototype of a tablet computer flexible enough to roll up like a newspaper. PaperTab was created by the Human Media Lab at Queen’s University, Canada, with the assistance of Plastic Logic, a U.K. company that makes flexible display technology. In Las Vegas, Aneesh Tarun and Roel Vertegaal from Queen’s showed off the prototypes, which still require tethering to a power source.
The Waterloo duo combined an off-the-shelf touch-sensing sheet with a black and white display from Plastic Logic that was 0.3 millimeters thick to make PaperTab. They included sensors capable of detecting when a corner of the device was bent, so that the flexing gesture could be used to turn the pages of an e-book.
