Remote collaboration has many benefits; however, due to the geographical distribution of learners, many misunderstandings can occur during interaction. For example, learners may miss the context of the discussion or do not hear parts of it, leading to inefficient discussions. In this paper, we propose an "Enriched Cyberspace" approach for dependable web based computer supported collaborative learning (CSCL) to overcome these problems. The system based on the approach assesses the situations of remote users through fusing information of multiple biological sensors and the related general contexts to enrich the cyberspace. A formative scenario evaluation demonstrates the feasibility and usefulness of the approach for developing effective web-based CSCL systems.
