交談式影碟教學系統發展的目的，在於發展可供設計教學課體的編輯系 統，本研究係嘗試以致學系統發展的規劃，來瞭解交談式教學系統研製的過程， 並逐步去實踐交談式教學系統的設計和實作。 文分四個部份:首先評論交談式影碟教學系統，其次談論其影像系統的畫面重疊 技巧，第三部份研究交談式影碟教學發展系統暨學習系統之差異性，第四部份則 探討其設計原則。 研究的重點在於發展中文的教學和學習系統為主，所以在其後續的研究，自然以 實際的整個系統運作和實體發展規劃為主要的思考重心。

　　　　　 This study strated from 1986, the original purpose of thestudy was to develop a multi-media instructional computercontrol system. Thus, video tape recorder, slides, audio taperecorder were all applied as tools for instruction. Owing to theweakness of poor timing in tape rewinding and cumulated errorcounting. Learners feel frustrated soon after several hours ofstudy, especially to those subjects need frequent changes fromone to another. In order to escalate learner's attention andmake study a natural easy way, this study concentrate on theinteractive video based instructional system. Followingobjectives related to the system development will be disscussedin this paper: 1. To discuss interactive video based instructional system. 2. To discuss image overlap techniques. 3. To discuss interactive video based instructional developing system and learning system. 4.Todiscuss principles of interactive instructional video based sysem.
