Augmented reality car windscreens

They will display phone calls and GPS information

Technology firm Harman is previewing its interative car windscreens at the Geneva Motor Show, which it claims will "transform the car into a mobile office - safely."

Harman's head up display system (HUD) shows the driver things like speed and distance to the car in front.

Incoming phone calls with the picture of the caller.

Weather conditions.

Arrows for navigation, directions and warnings of looming collisions.

This is a large amount of information being delivered into the driver's line of sight 

But Hans Roth, Harman's Director Technology Marketing, believes the information is delivered seamlessly enough that it won't be distracting nor dangerous.

With a wave of the hand, Mr Roth demonstrates how a driver could reject incoming information and silence phone calls should they feel the need.

HUD technology is already present in various luxury cars.

Mr Roth says Harman is working with car  makers to incorporate many of these new features into the next generation cars.
