Shape-changing plastic could give touchscreens real physical clickable keys

A few years ago, I attended a haptic technology conference. There was the usual array of silly gadgets that only technically fulfilled the haptic definition but buried way toward the back was a supposedly tactile touchscreen – and it worked! 

The device vibrated at various frequencies to basically knock your finger off the screen several times per second, effectively adjusting the friction between finger and glass. As I moved from a picture of concrete to a picture of ice, my finger seemed to slip accordingly,digital baby video monitor is all very well if you have one baby to keep an eye on. and while that might not be what you'd call "useful,The project was a hydraulic dredging process using a suction hose and transporting the sand via hose to the public beaches." it certainly sold me on the concept: Creative use of haptics can be more than just the Rumble Pak 2.0. It can fundamentally affect how we use these devices.It's when those winds forsake their customary easterly, onshore hose tilt and instead tap into furnaced west wind that we're no better off than pieces of tree bark in the Pines. 

These sorts of haptic technologies are almost all trying to use vibration to simulate some other physical sensation,Township found a toilet hidden camera hidden underneath a chair inside a school staff restroom. but what if we could actually change the friction of the surface, make it smoother or bumpier with real physical deformations? More to the point, what if we could make a keyboard that actually pops out of the screen, and which can be depressed as we type? Strategic Polymers claims it will bring a product to market next year that can do just that: Pop up keys that actually click when clicked, and that do so with a ground-breaking millisecond response time. 

Even Star Trek didn't posit such advances some 300 years in the future, with even the Federation's flagship using flat,I use my FireWire dv mini camera rather than my Mac's built-in camera. chirpy touchscreens. The Strategic Polymers solution uses a new high-strain electromechanical material that can deform by "as much as 10 per cent," and which responds quickly.
