Abstract
In this paper we propose a navigation system for motorcycle, using head-up display technology. By using a laser projector technology, we constructed a head-up display system provided by high contrast and brightness. The contrast and brightness provides high visibility to the driver capable to look and understand while driving during day or night. The usage of this system was confirmed by an experiment conducted using the prototype of head-up display system in the immersive CAVE environment, operated from a full-scale scooter type motorcycle simulator. The subject drove the motorcycle simulator in a virtual test course made based on a real town in Japan. We used an eye mark recorder to measure the subject's viewpoint. From the experiment, we conclude the head-up display navigation system is capable to provide navigation information without distracting the driver's viewpoint.t Experiment results indicated that showing information on the lower right or lower left positions are effective compared to other positions.
