摘要

 本研究試圖發展出一種互動式的電腦輔助運動教學法,來校正使用者的姿勢,以模擬教師般在學生旁邊親自指導,以達到及時指導的目的。

本系統是以消費性之USB攝影機作為取像的裝置,經由電腦及一套具有計時與紀錄功能的程式所組成的系統來執行。使用者身上須穿著特製的衣物,此衣物的形式為在肢體上以不同鮮豔的顏色作為區隔,以利程式的判斷。藉由攝影機的取像,將人體的肢體作分析,包括肢體顏色比例的分析、肢體角度的分析等,以分析後的數值作為比對的資料。本系統以太極拳作為學習之內容,數據化分析其動作姿態,同時達到推廣太極拳之目的。

ABSTRACT

 The purpose of this study is to develop an interactive method for the software of athletic training, which can correct the gesture of user to simulate a teaching system.

This system uses commercial USB cameras as the device of capturing, and consists of the computer and the program, which provide time counting and recording. The user must wear special clothes for recognizing. The color on the clothes will distinguish the body limb from the background. By the capturing of camera, the program then could analysis limb motion. The analysis includes the proportion of colored limb and the angle of limb. We take these values as the data of matching. Therefore, the system acquires the status of the user, and records the learning progress of the user, comparing with the past learning records such as his/her disadvantages. As a result, this system promotes the interest of learning effectively, and reaches the purpose of quick learning. We adopt Taichi as the content of this learning system, datalizing the motions and postures, in order to spread Taichi at the same time.
