Swedish company has brought to you a new device, AirBar, that would bring the touch technology to virtually any computer from your non-touch laptops to notebooks. AirBar is a small plug-and-touch bar that attaches magnetically magnetically to the bottom of your machine’s display. It starts emitting a beam of invisible light across your screen that is used to track touchscreen movements and gestures. It works well with any device running Windows 8 or Windows 10 or even with a Chromebook, but it still needs to have proper OS X support.
