Nokia's Haptikos tactile feedback tech revealed in patent application
It's been a while since we've heard anything about Nokia's Haptikos tactile touch screen technology, but with the unearthing of some juicy patent details, we finally know what's going on here. Basically, the tech uses layers under the touchscreen to allow control of surface roughness and friction. The patent describes a "plurality of closely space voltage controllable protruberances" that can raise or lower based on where the user is touching the screen, resulting in what feels like resistance and tactile feedback. Filled with fluid, the protruberances increase fiction and help users feel like they're actually touching something rather than poking at a plane of glass. No word on any devices with the new haptic tech, but we wouldn't be surprised to see this show up in some of their new touchy-feely handsets in the near future.[Via Unwired View]Read - Patent Application (warning: PDF)
Nokia shows off Haptikos tactile touch screen technology
Apple's already shown its interest in tactile touch screens, but it looks like Nokia is a bit further along in its own touchy feely endeavor, with it now showing off a prototype of its so-called "Haptikos" system. According to Red Ferret, Nokia's system is also a good deal more advanced than some similar ones already on the market, with it actually allowing for a 0.1 mm movement in the screen itself. That, combined with a pair of sensor pads under the screen, supposedly allows it to "mimic exactly the sensation of pressing a real key," complete with a "clunky click and tactile snap." What's more, it seems that the technology isn't all that far off, with Nokia's upcoming S60 handset apparently first in line to get it.
