    Artifact awareness through screen sharing for distributed groups
    (2008-06-16T22:25:36Z) Greenberg, Saul; Tee, Kimberly; Gutwin, Carl
    When co-located, people can see the artifacts that others are working on, which in turn enables casual interactions. To help distributed groups maintain mutual awareness of people’s electronic work artifacts, we designed and implemented an awareness tool that leverages screen sharing methods. People see portions of others' screens in miniature, can selectively raise larger views of a screen to get more detail, and can engage in remote pointing. People balance awareness with privacy by using several privacyprotection strategies built into the system. An evaluation with two groups using this system shows that people use it to: maintain awareness of what others are doing, project a certain image of themselves, monitor progress, coordinate joint tasks, determine others’ availability, and engage in serendipitous conversation and collaboration. While privacy was not a large concern for these groups, a theoretical analysis suggests that privacy risks may differ for other user communities.

    Artifacts as Instant Messenger Buddies
    (2008) Greenberg, Saul; Stehr, Nathan; Tee, Kimberly
    Artifact awareness is one person’s up to the moment knowledge of the artifacts that other group members are working with. Such awareness contributes to the overall information necessary for fluid group coordination and interaction. Yet current systems treat artifact awareness quite differently from the interpersonal awareness of group members using the artifact. Our approach differs. We exploit commercial Instant Messengers (IMs) for artifact awareness, where we treat an artifact – such as a document – as a 1st class buddy. As a person uses the artifact, changes are triggered in the artifact’s online, idle and offline state. Further information about artifact events is published to the IM’s ‘display name’ or ‘personal message’ field. Important artifact activities – such as major version updates – are delivered as chat messages. Others can engage in a chat ‘dialog’ with the artifact that includes directives to receive and transmit artifact versions. The group’s conversation around that artifact is also recorded as part of the chat history.

    Providing Artifact Awareness to a Distributed Group through Screen Sharing
    (2006-03-27) Tee, Kimberly; Greenberg, Saul; Gutwin, Carl
    Despite the availability of awareness servers and casual interaction systems, distributed groups still cannot maintain artifact awareness the easy awareness of the documents, objects, and tools that other people are using that is a natural part of co-located work environments. To address this deficiency, we designed an awareness tool that uses screen sharing to provide information about other people s artifacts. People see others screens in miniature at the edge of their display, can selectively raise a larger view of that screen to get more detail, and can engage in remote pointing if desired. Initial experiences show that people use our tool for several purposes: to maintain awareness of what others are doing, to project a certain image of themselves, to monitor progress and coordinate joint tasks, to help determine when another person can be interrupted, and to engage in serendipitous conversation and collaboration. People have also been able to balance awareness with privacy, by using the privacy protection strategies built into our system: restricting what parts of the screen others can see, specifying update frequency, hiding image detail, and getting feedback of when screenshots are taken.
