Neonode's AirBar uses beams of light to turn any laptop into a touchscreen laptop

Neonode's Air Bar is the latest PC accessory that wants to make traditional laptops all touchy-freely.

Ever since Microsoft so heartily embraced finger-friendliness with Windows 8, accessory makers have been striving to figure out a compelling way to add touch capabilities to non-touchscreen displays, be it in the form of fancy styli paired with infrared receivers, gesture control scheme like Leap Motion, or touch-sensitive overlays that you plop on your laptop’s display. But sadly, every single solution has been either lacking in functionality or just plain overpriced.

Enter Neonode’s Air Bar—potentially.

The AirBar’s a slim sensor that magnetically latches onto the bottom of your Chromebook or Windows laptop’s display and connects via USB. Once it’s hooked up—Neonode says it’s plug and play, with no extra drivers necessary—the device casts a beam of light across your screen, and you can poke, pinch, zoom, swipe and scroll around with your hand the way you would on a touchscreen PC.

Since the AirBar’s powered by light, rather than touch, you can use it to interact with your laptop in ways that traditional touchscreens don’t allow, such as with a glove or even chopsticks
