Abstract

Batting training practice aims at increasing the batting performance of baseball players. Traditional batting practice methods have been proven effective in increasing the players batting performance in real games. However, the feedback the player gets is limited to: the vibration of the bat, the sound of the impact and the ball trajectory. We propose a Virtual Reality-based (VR) baseball batting system that provides batters with instantaneous bat swing information as feedback. This information includes: exact bat-ball impact location and angle, replay for swing timing and speed. The ability to review this swing information immediately after each swing may help batters to quantitatively adjust their swing to improve batting performance. In order to evaluate its effectiveness, we compared the proposed method against a traditional batting training method, during a short period. Results of our preliminary experiments show that the VR-based group batting performance, after a 10-day practice period, was comparable to the traditional group. Further experiments and analysis are required to assess the efficiency of the proposed method.

Abstract

We studied highly realistic communication systems using a super multiview three-dimensional (3-D) video system. We propose the developed glasses-free 200-in. 3-D display using ∼200 high-definition (HD) projector units to reconstruct natural life-size 3-D moving objects, such as cars and humans. We also analyzed the optimal arrangement of the multiview camera system for the 3-D display. In the experiments, we developed a prototype super multiview 3-D camera system using compact HD video cameras with real-time convergence compensation circuits that correct the captured images via image processing optimized for the display. We also performed demonstration experiments using the developed 3-D display and camera system in a public area. As a result, we highlight several possibilities for actual applications of the glasses-free super multiview 3-D video system. [ABSTRACT FROM AUTHOR]
