Abstract
Our study deals with the development and evaluation of motorcycle simulator for understanding rider's control mechanism. For that purpose, we have been putting much effort for spherical screen visual system, since the effect to the rider's subject evaluation is shown in previous study. Adding to spherical screen, we made it clear that solid angle from rider's eyes should be wider enough to cover eyesight along the rider's range of head motion. To verify this, rider's subjective evaluations are analyzed by our proposal methodology. The quantitative results show usefulness for riding simulator design study.
