Designing Conversation-context Recommendation Display to Support Opportunistic Search in Meetings

Pierre Dillenbourg, Nan Li

In meetings, people sometimes come across information in the environment or in the conversation. This kind of ac- cidentally encountered information may be or not be rele- vant to the main meeting topic, but stirs people’s temporary interest and mediates g ...
