Providing location fixed route guidance implies that these aids have to be displayed by providing depth cues. This means they have to be displayed with a three-dimensional sensation of distance, so that the driver has an understanding of the aids position within the three-dimensional world. Additionally to enable the driver to anticipate which kind of maneuver he has to accomplish, it is essential that the navigation information is perceptible in great distance. Furthermore, in order to reduce the driver’s workload in comparison to common navigation systems route guidance information must be designed as natural and intuitive as possible.
Due to this issues the development of conformal indication postulates special requirements to the display device as well as to the design of the navigational aids.
Perceptibility in distance: With respect to the second mentioned issue there is a need that a wide range of possible indication distances can be covered. But the perceptibility of objects in distance is related to the spatial resolution of the display, which means displaying navigational aids at a great distance is limited to some extent.
Perception of depth: In terms of providing depth perception for location fixed arrows, some allusions can be provided by the design and rendering of the navigational aids. Which means supporting depth perception can be improved by cues which are inde- pendent of the display device.
Perceptibility in distance: Design constraints concerning the improvement of percepti- bility of the given information are crucial and unfortunately at the same time elusive aspects of research. Up to now no research has been done to identify or define impor- tant aspects to enhance the perceptibility. Considerations which visualization scheme does achieve the highest perceptibility in distance can only be done in an intuitive way and have to be proofed.
Intuitiveness: Providing intuitiveness of the provided information is complex issue, especially in the context of conformal indication, where no standards are set. Navi- gational aids must be designed efficient, easy to learn and satisfying to achieve the desired goal that concepts becomes easily understandable.

Title: | Presentation Concepts for Conformal Navigation Systems |
Abstract: | Integrated into the car, Head-up Displays (HUD) enable information presentation in the driver's windshield. This display combined with Augmented Reality enables extension of the street scenery with conformal (location-fixed) navigation aids. Navigational arrows then appear to be aligned onto the street and seemingly integrated into the real environment. The presentation of route guidance information generates new challenges for investigation. The main reason for the application of HUDs lies in reduced glance times. The focal plane of HUDs therefore must reach large distances so that the human eye does not have to adjust to another focal depth when viewing from the street scenery onto the HUD. To achieve the desired focal length, but to keep the opportunity of information presentation in near distance, a conformal HUD has been built placing the focal plane in a distance of about 13 meters in front of the driver. The virtual projection screen became blown up to cover a wide field of view. This approach lead to a large relative size of screen pixels. This setup impairs the distance at which AR information can be displayed. A navigational arrow for instance will have to less pixels to be perceivable in large distances. The development of an application for preliminary studies to identify distance limitations for different conformal visualization schemes therefore is scope of this thesis. Different design concepts for AR navigation aids will be evaluted in terms of their perception in large distances |
