With increasing size of Head-Up Displays and sensor technology Augmented Reality gains the potential to be used in automotive environments. Head-Up Displays provide a third dimension for information presentation. The increased dimensionality and the fact that the display space contains the outside environment which is essential for safe driving generates new opportunities for information presentation but also new issues. This paper collects the common principles for information presentation in the Head-Up Display and classifies these in according dimensions. Pair-wise combinations of the classes are used to illustrate examples for presentation concepts. Awareness about the different concepts and their underlying principles enables avoiding potential cross-relationships between multiple dimensions and thus enables unique attributing of effects in user studies.
