在棒球比賽中，臨場戰術的執行相當重要，勝敗的關鍵除了取決於平日的動作訓練以外，球員對戰術的觀念是否正確，也深深影響著戰術執行的成功與否。藉由資訊科技的協助，本文提出一個應用於棒球場上戰術演練之動畫編輯系統，並探討其設計思維與實作後之成果。 此系統能夠針對棒球比賽中，過去發生或可能使用到的棒球戰術進行編輯儲存，並以動畫方式顯示棒球與場上球員的移動軌跡，同時展現在特定時間下，相關球場物件的相對空間位置及時間關係。期望透過此種案例編輯與動畫播放的方式，來增進球員的學習效率與溝通速度。編輯完成的戰術案例，也能以檔案形式儲存起來，方便後續的重覆觀看、複製分享及再度編輯創新。

The successful and timely execution of a baseball strategy in is very important in baseball games. The key point for this successful execution of a player not only depends on the daily practice routine but also depend heavily on the correct concepts of the player. In this article, we discussed the concept for baseball tactic training and the implement of an editable animation demonstration system with the help of modern technology. Baseball strategies, whether currently used or selected from the past, can be easily created, collected, reedited and stored in this system. It can also provide the moving trajectories of the ball and players in the field, and can display the relationship between spatial position and time interval by a computer assisted animation way. We hope that, by using this system, coaches and players can get a better training results and increase communication efficiency. The strategy cases, after the editing processes, can be stored as digital files permanently, reviewed repetitively, shared with others and reedited easily.
