Augmented reality—right on your windscreen
Thanks to their ever-shrinking package size, dynamic GUI, and wider FOV, AR-HUDs are expected to gain traction with growing vehicle autonomy
Essentially a variant of the windscreen HUD, the AR-HUD supplements the exterior view of the traffic conditions in front of the vehicle with virtual information (augmentations) for the driver. Development of an AR-based HUD can be accredited to Pioneer Corporation, which in 2012 introduced a HUD navigation system that replaced the driver-side sun visor to visually overlay it with animations of conditions ahead. This version of the AR-HUD became arguably the first aftermarket system to use a direct-to-eye laser beam scanning method, also known as virtual retinal display (VRD). The core technology of this AR-HUD involved a miniature laser beam scanning display developed by MicroVision, Inc. With various driver-assistance features already a reality and full vehicle autonomy just around the corner, automotive user interface and experience is fundamentally changing. AR-based HUDs are bound to play a significant role in future cars owing to their ability to provide real-time safety-pertinent information like speed limit, lane departure warning and adaptive cruise control information to the drivers directly in their line of sight.
