windshield HUD accounting for half and the combiner the other half. And Spoelder goes on to say that HUD technology is really on an upswing, with more development to come. Augmenting Reality But the big story—bigger than the non- trivial market that HUD represents—is that there is a large group of people within Continental—ranging from physicists to cultural anthropologists, from graphic designers to electronics experts—who are developing an Augmented Reality Heads-Up Display (AR-HUD). Speaking to this technology, Dr. Pablo Richter, who is with the Continental Interior Div., says, "The AR-HUD optical system enables the driver to see an augmented display of the status of driver assistance systems and the signifcance of this information in their direct feld of view." He adds, "As a new part of the human-machine interface, the current, pre-production AR-HUD is already closely connected with the environmental sensors of driver assistance systems, as well as GPS data, map material, and vehicle dynamics data." While it is at a pre-production stage right now—meaning that the trunk of the Kia K9 sedan is chock-full of processors and as we drive the car, Dr. Richter is in the back seat, monitoring how things are operating—plans call for the AR-HUD to be ready for serial production in 2017. The "augmented" part means, in efect, "additional." There is more information provided by this system than is the case of a conventional HUD. This information is supplemental. So for a conventional HUD, you might see your speed. With an AR-HUD, that doesn't go away. It is still there. But (1) it is positioned in virtual space in a diferent place and (2) it is joined by additional information. In the case of the Continental demonstration vehicle, the additional information relates to adaptive cruise control (ACC), route guidance from the navigation system, and lane departure warning (LDW). As regards the projection planes, the conventional HUD information is considered "near." That is, once the driver orients herself so that the HUD display is viewed in a centered way (i.e., a given driver will adjust the seat position and height for purposes of driving the vehicle; consequently, there needs to be an adjustment vis-à-vis where the information is projected on the screen, which can be accomplished through the use of a dial on the instrument panel). This is known as establishing an "eye box." The near p This is a heads-up display unit, which is inserted into the top of an instrument panel. This particular unit is produced by Continental for use in the new Mercedes C-Class. AD&P; > September 2014 > FEATURE > Continental: Heads Up > Gary S. Vasilash > gsv@autofeldguide.com 36
