Head-up display for motorcycle navigation

In this paper, we describe a navigation system for motorcycle using the technology of head-up display. While there are various navigation system products for automobiles, motorcyclist has issues in using currently provided navigation system. It is known from previous researches that motorcycle rider moves their viewpoint in a characterful way while driving, which makes it difficult for the rider to look at small liquid crystal displays. To solve this issue, we propose a navigation system utilizing the technology of head-up display. While considering the motorcycle rider's viewpoint behavior, we constructed a head-up display to conduct experiments and observe the effects by presenting information on the head-up display. Regarding safety, experiments were conducted inside an immersive projection environment using a motorcycle simulator. The results of experiments clarified the preferable display position and the amount of information to present on the head-up display.
