BirdView™ Navigation flies

Coming up in several new models, Nissan will introduce a navigation system based on a bird's eye view of the maps. Traditional navigation systems direct the driver through planer maps. Plane maps require switching from wide, zoomed-out to detailed, zoomed-in versions of the mapping area, potentially distracting the driver's view of the road.
"Our results showed that to make a safe navigation system we needed to develop a system that would do both of these functions simultaneously, so we came up with the BirdView idea," recalls Hiroshi Tsuda, director of Intelligent Transportation Systems at Nissan.
BirdView™ places the driver's viewpoint at an altitude of 350M and 1 km behind the vehicle. This view creates a trapezoidal shape of 500M at the bottom of the screen, 7 km at the top of the screen, and a spanning view of 7 km. The driver can see simultaneously a detailed view of the intersection at the lower part of the screen for guidance on what turn to make, while the upper portion of the screen displays a zoomed-out view so the driver can anticipate the distance of the next intersection.
