DIVER: Distributed Collaborative Analysis of Video Records in the Human Sciences

该合同支持基于web的应用程序的设计和原型开发，用于人文科学领域视频记录的协同分析。这个应用程序，DIVER（数字交互式视频探索和反思），解决了合作实验室的关键需求。人文科学中的功能，其中公共工具和人类交互数据集的共享语料库可用于研究理论和实践问题。拟议的努力将利用NSF-MRI奖（NSF-0216334）进行相关工作，并利用2002年11月下旬nsf资助的创新学习技术中心（CILT）数字视频查询研讨会。CILT研讨会将向NSF项目研究人员、研究生和教师研究人员介绍该工具，并使他们参与DIVER的进一步设计和开发。对于旨在帮助构建和服务用户社区的应用程序来说，这些反馈是至关重要的。DIVER应用程序将由一个保存视频数据分析的服务器组成，包括视频源和一系列在时间和空间上裁剪的注释选择。观看DIVER分析的观众将能够使用与原始分析中的特定场景相关联的线程讨论进行回应，并且他们可以根据自己的回应返回到基本视频剪辑中创建自己的选择。需要解决几个实质性的技术问题，其中主要是在web浏览器环境中对多媒体记录的操作，以及复杂的注释多媒体文档的存储、索引和检索。

This award supports the design and prototype development of a Web-based application for collaborative analysis of video records in the human sciences. This application, DIVER (Digital Interactive Video Exploration and Reflection), addresses a critical need for .collaboratory. functions in the human sciences, where common tools and a shared corpus of human interaction datasets can be used for investigating questions of theory and practice. The proposed effort will leverage an NSF-MRI Award (NSF-0216334) for related work and capitalize on an NSF-funded Center for Innovative Learning Technologies (CILT) workshop on Digital Video Inquiry in late November 2002. The CILT workshop will enable the introduction of the tool to a community of NSF project researchers, graduate students, and teacher-researchers, and to engage them in the further design and development of DIVER. This feedback is crucial for an application that is intended to help constitute and serve a community of users. The DIVER application will consist of a server holding analyses of video data, consisting of video sources and a series of annotated selections cropped in both time and space. Viewers of a DIVER analysis will be able to respond using threaded discussions attached to particular scenes from the original analysis, and they can return to the base video clip to create their own selections as their responses warrant. Several substantial technical issues, primary among them the manipulation of multimedia records in a web browser environment, and the storage, indexing, and retrieval of complex annotated multimedia documents need to be resolved.
