This paper introduces a text-based chat system designed to support conversations anchored to specific locations of shared images and reports our experience in operating it at a technical conference. Our system is unique in that it focuses on supporting communications scattered around among multiple images, while other systems for anchored conversations are designed for deeper discussions within a single document. Our system was used in a technical conference as a space for anchored conversations over presentation slides and we observed that audiences actively participated in discussions during the presentation. The detailed chat log was also useful for both audiences and presenters.
