We advocate a new approach to meeting video retrieval based on the use of memory cues. First we present a new survey involving 519 people in which we investigate the types of items people use to review meeting contents (e.g., minutes, video, etc.). Then we present a novel memory study involving 15 subjects in which we investigate what people remember about past meetings (e.g., seating position, etc). Based on these studies and related research we propose a novel framework for meeting video retrieval based on memory cues. Our proposed system graphically represents important memory retrieval cues such as room layout, participant's faces and sitting positions, etc.. Queries are formulated dynamically: as the user graphically manipulates the cues, the query results are shown. Our system (1) helps users easily express the cues they recall about a particular meeting, and (2) helps users remember new cues for meeting video retrieval. Finally, we present our approach to automatic indexing of meeting videos, present experiments, and discuss research issues in automatic indexing for retrieval using memory cues.
