Hypermedia conversation recording to preserve informal artifacts in realtime collaboration

摘要

We present a hypermedia-based conversation recording method to preserve informal artifacts which are obtained in a realtime collaboration. Informal artifacts are not final goals but important results such as a process of a decision, an individual opinion, a rejected idea, or a nuance. Conversation in a realtime collaborative session is recorded linked with a participant's handwritten scripts so that the relevant portion of the conversation can be selectively played back in the subsequent individual session. A participant can preserve informal artifacts and structure the decision-making process by playing back the conversation after the collaboration. The important feature is that a participant can insert meaningful cues in any portion of the conversation without disturbing the current way of collaboration. Through the use of a prototype, we have found the effectiveness and the further improvement of this method.
