This device called Airbar projects an invisible light field on the surface of any laptop display that makes it possible to “touch” the screen and interact with it.
The Airbar sensor uses Neonode’s zForce AIR™ technology which can be used for all sorts of cool stuff. The light field reacts to any kind of gestures like raising your hand. It works with anything lie using your fingers, gloves, brush.
You can plug and touch instantly by attaching the magnetic strip and plug in the USB port. Touch your laptop even if it’s not a touchscreen device and you can use any gestures from pinching, swiping, zooming and scrolling away.
