What do you do when you have a thousand video clips? How can we design applications and architectures to support the repurposing of video and audio information? What models of human-computer interaction will help us in constructing environments for working and playing with content-annotated media? To approach these and other questions we will focus on three principal subject areas: models of human-computer interaction and their effects on the types of artifacts we design; enabling technologies for current and future new media applications; and a detailed discussion of a research prototype for annotating, retrieving, and repurposing digital video. In discussing different models of human-computer interaction, we will examine old and new concepts of communication and their corresponding 'closed' and 'open' multimedia architectures. In investigating open multimedia architectures, we have focused on the design of 'reusable' media. Media Streams, the research prototype we will discuss, takes a departure from traditional 'clip-based' representations of video content inherited from single-use applications and utilizes a 'stream-based' representation in order to support the repurposing of annotated temporal media. In addressing the challenges of describing, visualizing, and manipulating video information, we combine automatic and human-assisted annotation of media content, use multiple views of video data at different spatial and temporal granularities, wrestle with issues of consensus and idiosyncrasy in shared representations, and have developed a visual language of cascading, compound, and animated icons for describing the complex structure of video and audio. |
