Meet AirBar: a smart sensor that brings touch to your new or existing PC. It projects an invisible light field over your screen, allowing you to interact with apps no matter what type of glove you are wearing. You can pinch, swipe, zoom, and scroll on devices that don’t have a touchscreen display.
AirBar is a plug & touch device. It does not drain your battery either. You can order it for 15.6″ laptops for under $50.
