Theme Article: Special Section on Human Centric AR&VR Display and Human Interface Technologies for Automobile Motorcycle Head-Up Display: Design of Presenting Navigation Information Kenichiro Ito The University of Tokyo Tetsuro Ogi Keio University Hidekazu Nishimura Keio University Abstract-Navigation systems for motorcyclists are gaining attention using state-of-the-art technologies. While it is expected to provide benefits to riders similar to the technologies used for automobiles, the effectiveness of motorcycle head-up and head-mounted displays is not yet well understood. Therefore, this paper presents a human-centered design approach using a prototype of a motorcycle head-up display and an immersive virtual reality simulator. For validation, the motorcycle head-up display was equipped on a commercial motorcycle and tests were conducted in the real-world environment. & MANY NAVIGATION SYSTEMS have been introduced for automobiles, though not for motorcycles. However, the demands of a navigation system dedicated to motorcycles are considered to be high, indicating lack of useful products on the market. Some motorcycle riders use smartphone applications for navigation, however, the riders have difficulties obtaining Digital Object Identifier 10.1109/MCE.2019.2923934 Date of current version 30 August 2019. 74 2162-2248 ß 2019 IEEE information while riding. Earlier studies indicate that motorcycle rider's move their viewpoints on the road surface more careful than automobile drivers as a slight obscurity on the road could make the motorcycle unstable.1 Recent studies propose concepts utilizing state-of-the-art technologies such as head-up display (HUD) to provide information near where the riders are considered to be looking. HUDs are effective for automobiles, though it is carefully controlled regarding distraction against the driver.2 Published by the IEEE Consumer Electronics Society IEEE Consumer Electronics Magazine
