Product details:

It is a groundbreaking piece of technology that emits an invisible light field that covers your PC display. Just mount the discrete device right underneath your display and plug in the USB port. When the light field is interrupted by your fingers, pencils, brushstrokes or virtually anything the computer interprets this as interactive input. This means that with AirBar if you have a PC running Windows 8 or Windows 10 or Chromebook, you can turn your non-touch PC into a fully functioning touch enabled PC. AirBar projects an invisible light field on the surface of your display that makes it possible to "touch" the screen and to interact with Windows 8 and 10 gestures.
