Audi is already planning the next development in head-up display technology – the “high-fidelity head-up display”. This makes it possible to seemingly position the displays in the real environment. A navigation arrow, for instance, is no longer perceived as being at a fixed distance over the front lid; it is now directly at the junction that it is indicating. The arrow increases in size as the car approaches the junction. It remains over the junction, appearing to come nearer to the driver.
The new technology, which has already reached prototype stage at Audi, brings many tangible advantages. The display always lies ideally in the field of view and the eyes can always remain focused on long-range objects. The driver registers information even quicker and is distracted less.
Considerable technical work has gone into the high-fidelity head-up display. An on-board camera scans the surroundings in front of the vehicle. Ultra-high-performance software compares the images with the predictive route data in the navigation system and converts them into a matrix in which it embeds the displays. This technology is currently still at the prototype stage, but Audi expects it to reach maturity in a few years’ time.
