Check out this awesome gadget that will turn ANY computer monitor into a touch screen panel. 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. How does this happen? Well, 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.
