DLI-Phase 2: An Intelligent Authoring Tool for Non-Programmers Using the Informedia Video Library

摘要IIS-9817527迈尔斯，布拉德·卡内基梅隆大学，150,000-12,000美元。使用Informedia数字视频图书馆制作多媒体材料这是连续三年的奖项的第一年资助。该项目将创建一个全面的智能视频编辑器，将允许人们在没有特殊培训的情况下使用数字视频创作有趣的作品。特别是，该编辑器将支持视频的复杂交互行为以及覆盖在视频之上的额外图形绘制(称为合成图形)。例如，用户可以指定可以单击视频中的哪些对象来选择下一个视频剪辑，或者应该绘制一个箭头来显示对象将遵循的路径，或者指定视频是课程的一部分，观众对问题的回答决定下一步操作。还将有用于搜索和组织视频、视频编辑、演示行为、用更自然的编程语言编写脚本以及测试和调试代码的高级设施。创建的工具将在学龄儿童和成人中进行持续测试，以评估和改进各种功能。其目标是使使用数字图书馆中的视频材料和使用今天图书馆中的文本材料一样容易。

Abstract IIS-9817527 Myers, Brad Carnegie Mellon University$150,000 - 12 mos.Using the Informedia Digital Video Library to Author Multimedia Material This is the first year funding of a three year continuing award. This project will create a comprehensive Intelligent Video Editor that will allow people without special training to author interesting compositions using digital video. In particular, the editor will support sophisticated interactive behaviors for the videos and for extra graphical drawings (called synthetic graphics) layered on top of the videos. For example, users might specify which objects in the video can be clicked on to choose the next video clip, or that an arrow should be drawn that shows the path that an object will follow, or that the video is part of a lesson and a viewer's answer to a question determines the next action. There will also be high-level facilities for searching and organizing videos, video editing, demonstrating behaviors, writing scripts in a more natural programming language, and testing and debugging the code. The tools created will be continuously tested with school children and adults to evaluate and refine the various features. The goal is to make it as easy to use the video material found in a digital library as it is to use textual material found in today's libraries.
