RECOLED: A group-aware collaborative text editor for capturing document history

This paper presents a usability analysis of RECOLED, a shared document editor which supports recording of audio communication in remote collaborative writing sessions, and transparent monitoring of interactions, such as editing, gesturing and scrolling. The editor has been designed so that the collaboration results in the production of a multimedia document history which enriches the final product of the writing activity and can serve as a basis for post-meeting information retrieval. A discussion is presented on how post-meeting processing can highlight the usefulness of such histories in terms of tracking information that would be normally lost in usual collaborative editing settings

Supporting Remote Collaboration through Structured Activity Logging

This paper describes an integrated architecture for online collaborative multimedia (audio and text) meetings which supports the recording of participants' audio exchanges, automatic metadata generation and logging of users editing interaction and also information derived from the use of group awareness widgets (gesturing) for post-meeting processing and access. We propose a formal model for timestamping generation and manipulation of textual artefacts. Post-meeting processing of the interaction information highlight the usefulness of such histories in terms of tracking information that would be normally lost in usual collaborative editing settings. The potential applications of such automatic interaction history generation range from group interaction quantitative analysis, cooperation modelling, and multimedia meeting mining
