The AirBar is a sensor that adds touch capability to a PC screen. The device simply plugs into a USB port and lays at the base of a computer screen running Windows 8 or Windows 10 and allows users to make Windows touch screen gestures like pinching, zooming, and scrolling.
The plug-and-play design does not require any additional software installation or setup, and because the sensor works with a light field, the touch feature works with any material, not just fingers or a stylus.
