1 Vol.18 No.4, Evaluation of the Position to Present Information Using the Head-Up Display for Motorcycle Rider Kenichiro Ito 1, Yoshisuke Tateyama 1, Hidekazu Nishimura 1, and Tetsuro Ogi 1 Abstract This paper proposes a navigation system using head-up display technology for motorcycle. Indicated in earlier studies, motorcycle riders are acknowledged to perform characterful viewpoint movement while driving. Since currently provided navigation systems designed to attach a display to the handle bar does not take in consideration about this viewpoint movement, it is known that riders face difficulties to look at the attached display while driving. To solve this issue, we introduce the head-up display technology to be used as a display device for navigation system. To confirm the use of the head-up display, we developed a head-up display to evaluate the effective position to present information. For the evaluation environment, we used the immersive motorcycle simulator attached with the head-up display. Utilizing the simulator, we conducted an experiment to navigate the rider by presenting direction information like arrows in 9 different positions on the head-up display. We recorded the rider s viewpoint movement using the eye-mark recorder, and measured the duration of time spent looking at the presented information. The experimental results indicated showing navigation information on the lower right or lower left positions are effective when navigating the rider using the head-up display. Keywords : Head-up Display, Navigation System, Motorcycle, CAVE Simulator, Virtual Reality 1. [1] 1970 [2] [3] [1] 1 1 Graduate School of System Design and Management, Keio University 2.
