Abstract: The social mirror visualizes the process of a meeting. Meeting participants can see their own social behavior and that of others in a visual representation. The provided insight in one’s social behaviour by the Social Mirror might lead to changes in the behaviour that result in higher performance and satisfaction.

System set-up

Each participant has their own user interface on a tablet pc. In the beginning of the meeting each participant draws his own avatar using an interface on their tablet-pc. These avatars are used to represent the participants visually on shared screens. The visualization on the shared table screen shows which avatar belongs to whom. The avatars are positioned in front of the associated participants. The Social Mirror is projected on the shared vertical screen. During the meeting the participants have their own local view of the Social Mirror on their Tablet-PC.

The size of the avatars in the Social Mirror show how much the participants have spoken during the meeting. Meeting participants that have relative large avatars have spoken more during the meeting. By using this information participants can make inferences about their own and others level of dominance, activity and contribution.

Interaction between participants

The visualization shows the degree of interaction between the participants. Each link between two avatars is created based on alternating turns in speaking. The assumption is that a person that speaks right after another person is often reacting on what the previous speaker said.


At set moments in the meeting, the meeting chairman interrupts the meeting and asks the participants to explicitly choose their agreement or disagereement with other participants on a color map. Each color on this color map indicates a different option that the meeting chairman puts forward. Participants can drag and drop their avatar to a position that represents his/her (dis)agreement, using the Social Mirror interface on his tablet-pc. During the meeting participants can show their agreement with an argument by moving their avatar toward or away from the avatar of the person making the argument.
