How to Convert any Laptop Into a Touchscreen (Updated 2017)
What is AirBar and How does it Work?
AirBar is a small plug-and-touch bar that attaches magnetically to the bottom of your laptop’s display.
When connected to your laptop via an available USB port, AirBar starts emitting a beam of invisible light across your screen that is used to track touchscreen movements and gestures.
The movements and gestures are then translated into corresponding inputs, making you able to use all the gestures including pinching, swiping, zooming, tapping and scrolling around with your hand, in the same way, like on a touchscreen PC.
