verbal conversation clock
30 October 2007
a real-time data visualization projected on a physical table that aims to augment the developing verbal dialog by displaying a representation of conversation to all people present. the visual graph on the table demonstrates turn-taking, domination, interruption & activity throughout a conversation.
the Conversation Clock uses tick marks along concentric rings. just like a clock, each ring contains a single minute of tick marks. the inner rings represent earlier times in the history of the conversation. each mark is colored according to the microphone from which input was received & sized to indicate the amplitude of the associated waveform. as a result, phenomena like activity & turn-taking become easy to observe, such as people not speaking versus dominating the conversation, or aspects such as interruption, silences, and argument also make visual impressions on the table.
