Experimental evaluation of an augmented reality visualization for directing a car driver's attention

With recent advances of head-up display technology in cars, augmented reality becomes interesting in supporting the driving task to guide a driver's attention. We have set up an experiment to compare two different approaches to inform the driver about dangerous situations around the car. One approach used AR to visualize the source of danger in the driver's frame of reference while the other one presented information in an egocentric frame of reference. Both approaches were evaluated in user tests.
