Autodesk researchers develop 'magic finger' that reads gestures from any surface (video)
By combining a camera that detects surfaces with one that perceives motion, Canadian university researchers and Autodesk have made a sensor that reads finger gestures based on which part of your body you swipe. The first camera can detect pre-programmed materials like clothing, which would allow finger movements made across your pants or or shirt to activate commands that call specific people or compose an email, for instance. Autodesk sees this type of input as a possible compliment to smartphones or Google Glasses (which lack a useful input device), though it says the motion detection camera isn't accurate enough yet to replace a mouse. Anyway, if you wanted that kind of device for your digits, it already exists -- in spades.
Disney's REVEL could turn the whole world into a tactile touchscreen (video)
Disney Research think it can go one better on Tactile and Haptic touch displays by using electrical fields to add sensation to nearly anything you can touch. Using Reverse Electrovibration, REVEL works by strapping an electrostatic signal generator to your body, so when you come into contact with an object on the same electrical plane, that low-level field can be altered to create friction. It's hoped that the technology could revolutionize touchscreens, add a whole new level of feeling to augmented reality and help blind people feel their way around. There's a video after the break, but be warned, it's light on the sort of cartoony hijinks you'd normally expect from the House of Mouse.
Double-sided transparent touch display would make Battleship amazing
You've got to feel bad for the vendors at the Sign and Display Show 2008 that's going on in Tokyo right now for being totally overshadowed by IFA, but this nifty dual-sided transparent touch display from Teraokaseiko is definitely noteworthy, even if it just because it'll make future versions of Battleship and Connect 4 super fun. It's just a monochrome 256 x 120 EL-panel prototype for now, but it recognizes simple multitouch gestures like pinching, and there's definitely promise in the idea -- now if it could make it out of the Sign and Display Show and into the big leagues, we'd be all set.
