一個支援三維電子故事書的描述語言及其播放系統之設計與製作

Abstract

由於製作一部多媒體的三維電子故事書所需的人力眾多，包括腳本撰寫人 員、美工人員、程式設計人員．．．等等。所以，開發一部多媒體的三維 電子故事書時，進度很難控制，軟體的品質更難掌握，因此，發展一套輔 助軟體工具來協助開發多媒體的電子故事書是非常必要的。 我們的目標是設計一個三維電子故事書的發展環境，發展一個可以支援三 維電子故事書的描述語言及播放系統，來協助發展電子故事書這類的多媒 體的軟體產品。 我們的描述語言在製作動畫效果、語音同步的控制、使用者的互動交談能 力以及三維物件得使用、立體動畫上，都有提供的功能。因此，只要利用 描述語言來撰寫故事書的腳本，就能產生具有互動交談式功能的三維電子 故事書的軟體產品。整個系統是根據軟體再利用的觀念，物件導向的技術 來設計的。我們也利用此描述語言，實作一個簡單的實例來展示其可行性 ，以及所具有的能力。 To create a 3D multimedia electronic story book, it takes lots of efforts and requires the use of a variety of specialists, including script writers, animation designers, and programmers. Generally, it is difficult to control the progress and the quality of the software product of a 3D electronic story book. Hence, it is necessary to develop a case tool to ease the tasks of design and implement a 3D electronic story book. Our objective is to provide tools for supporting the development of a 3D electronic story book. In this research, we focus on the design a script language for describing 3D electronic story book scenario and the design of a playback system for the presentation 3D electronic story book. The proposed script language supports features such as producing the effect of animation, synchronizing text and voice, interacting with users, and providing 3D objects for animation. The overall design for these features is based on the idea of software reuse and object-oriented implementation technique. Based on the script language, an example of 3D electronic story book is designed and implemented to demonstrate its applicability and the features supported in this tool.
