If you’ve ever wanted to turn your laptop screen into a touch screen, your prayers have been answered. The Neonode AirBar turns any laptop into a touchscreen ($49). AirBar projects an invisible light field on the surface of your display allowing you to touch the screen and interact with Windows 8 or 10 gestures. This kind of tech is perfect for designers, teachers, and pretty much anyone who gives presentations. AirBar is available for pre-order at the moment. They say that a PC version is coming soon, and if you have a Mac, you’re out luck. There’s limited functionality for OS X, but no official support.
