The purpose of this study was to analyze visual tracking strategy during hitting in baseball batters. Eighteen subjects recruited from baseball team of Shin Hsin University. The iView Head-mounted Eye tracking Device was used to measure visual tracking strategy. Each subject wore it and looked at pitching movement that projected on the screen. Video Studio 10 was used to film the process. The viewing sites were defined as pitchers’ forearm, upper arm, head, body, lower extremity, and not-on-body. The results showed that batters looked at entire pitching movement during wind-up phase. Batters mainly viewed on pitcher’s lower extremity during lift-leg phase. There were significantly differences among forearm and other viewing sites during maximum stride phase. Forearm was a main viewing site during ball release phase. Therefore, baseball players have a certain visual tracking strategy. This proper strategy can help to discriminate pitch well and increase hitting performance.
