Abstract
Our ultimate goal is development of sports training equipments in which visual and force feedbacks are effectively utilized for general sports training. For this purpose, it is important to investigate how humans improve their motion basing on visual and/or force information. In this research, we experimentally investigate how visual and / or force information should be displayed for training persons in order to improve their motion performance. In this experiment, a mechanical system with one degree of freedom is used to display appropriate force signals and a projector provides training persons with visual information. From the experimental results, several important issues in the future research have been made clear.
