AirBar

AirBar projects an invisible light field on the surface of your display that makes it possible to "touch" the screen and interact with Windows® 8 and 10 gestures. This is all thanks to Neonode's zForce AIR™ technology, which can be used for all sorts of cool stuff. The reason you can use anything to touch is that the light field reacts to any disturbance. AirBar, created by Neonode, is a small bar that magnetically attaches to a bottom of a laptop screen, plugs into a USB port, and then emits an invisible beam of light to track movement and convert the standard screen into a touchscreen. Unlike traditional touch screensthough, Airbar works with fingers, brushes, gloves, and even chopsticks. When you’re done and need to pack everything up, you just need to unplug the device and slide it off your laptop. Enjoy the pure joy of finally pinching, swiping, zooming and scrolling on your PC without a touchscreen. You can even do it with gloves.
