Challenges and perspectives for True–3D in car navigation

Abstract

In the past years car navigation systems have significantly developed. Beside many important features to support drivers the advanced graphics is the most visible part. After starting with simple arrows and numbers, maps were displayed in order to provide hints for the spatial orientation of the driver. Later on, those maps were rendered perspectively in bird’s eye view and finally 3D data was integrated to generate more realistic views using city models and terrain models. However, one drawback of these 3D navigation systems is the use of monoscopic displays. Using these displays, the only way to mediate spatial depth has been to facilitate monoscopic depth cues. Whereas for desktop computers stereoscopic displays are used in order to allow a better depiction of 3D scenes, they were not used for mobile navigation systems yet. Since this application field has specific characteristics and requirements, this paper addresses the challenges and perspectives for the use of (auto–) stereoscopic displays in prospective car navigation systems.
