Abstract
Although current online chat environments provide new
opportunities for communication, they are quite constrained in
their ability to convey many important pieces of social
information, ranging from the number of participants in a
conversation to the subtle nuances of expression that enrich face
to face speech. In this paper we present Chat Circles, an abstract
graphical interface for synchronous conversa-tion. Here, presence
and activity are made manifest by changes in color and form,
proximity-based filtering intuitively breaks large groups into
conversational clusters, and the archives of a conversation are
made visible through an integrated history interface. Our goal in
this work is to create a richer environment for online
discussions.
