A part of the Sametime user interface that allows users to be aware of the online presence, or lack of online presence, of other people. An awareness component may be in its own window or frame, or inline with text or graphics; it may be just a sound that is audible when the user does a mouseover. Currently, there are three awareness components in Sametime: Who is Online, Who is Here, and active names. See also active name, Who Is Here, Who Is Online.
