MacBook Air: A touching story

In January 2017, optical-sensors specialist Neonode revealed that it updated its AirBar device to function with Apple’s MacBook Air notebook computer, which will allow for touch-screen and gesture-based operation.

All of Neonode’s AirBar devices connect magnetically to the bottom of a notebook computer’s display. They don’t require software installation or additional configuration, according to the company. An invisible “light field” senses touch on the display from fingers, gloves and a paintbrush, Neonode says.

As of press time, Neonode expected that the AirBar for MacBook Air would go on sale in early March 2017 for $99 at
