A group mirror for conversations
Reflect is an interactive meeting table that monitors the conversation taking place around it via a thee-microphone beamforming array, and uses a matrix of 8×16 multi-color LEDs to display information in different forms. We studied two versions of the table. The first shows the amount of speech of each participant, and our studies showed that, under certain conditions, participants become more balanced in terms of how much they speak when their participation levels are displayed on the surface of the table. This is beneficial for certain situations where balance in participation is necessary for good collaboration to take place, such as situations of collaborative learning where all learners need to participate more or less equally to improve learning gains for the group.
