Digital mirrors are expected to feature in next generation cars. Ongoing technological developments in on-board cameras, sensors and sensor-fusing algorithms means that future drivers could be provided with novel visualisations that are not limited to traditional reflective mirror views. Comparing a traditional, egocentric, rear-view side mirror with novel, exocentric top and side views (all presented on a ‘digital mirror’ display inside a stationary vehicle), the study exposed 25 participants to 36 passing pedestrian scenarios to explore their ability to accurately locate the pedestrian, with the ultimate aim of reduce potential ‘dooring’ accidents. Overall, relative depth judgement was significantly more accurate when using the exocentric top view compared to the egocentric and side views. The top view also attracted the highest confidence and lowest ratings of workload. The study demonstrates clear benefits associated with enhanced, exocentric visualisations presented on internal digital mirrors to assist drivers in hazard detection and localisation.
