In this paper, Seung Jun Kim and Anind K. Dey are developing an augmented reality windshield display that will aid in navigation and reduce distractions and cognitive load for the user. Many elderly drivers find it difficult to focus on the road and use a GPS device at the same time. This windshield would superimpose a map on the windshield that came down to meet the road. This would hopefully make it easier for the elderly to navigate in the car and to reduce the amount of required eye movement.
In their experiments, Kim and Dey created a driving simulation that gave the user a route to follow that included several turns, traffic signals, stop signs and pedestrians. The user would complete one route using a standard GPS device and then complete a different route using the AR display. The study was conducted with both elderly (>65) and younger (19-41) drivers. They also used a gaze tracker to track eye movement. In the experiment, the participants were far less likely to miss turns or violate traffic laws when using the AR simulation as opposed to the standard GPS. It was also discovered that there was far less eye movement and distraction.
I would love to have this kind of display in my car. I don't have GPS so when I am traveling somewhere new, I print out a map. This can be difficult because I don't always know my exact position on the map and trying to read the directions while driving. This would make navigation so much easier and safer. I would like to see this implemented in an actual car and see if in a similar study, the same results are found. However, like Kim says in the paper, this just cant be done very well yet.
