    CHANGE AWARENESS IN SOFTWARE ENGINEERING USING TWO DIMENSIONAL GRAPHICAL DESIGN AND DEVELOPMENT TOOLS
    (2000-10-19) Tam, James; McCaffrey, Lorin; Maurer, Frank; Greenberg, Saul
    In this paper, we discuss several display mechanisms for representing changes in the UML (Unified Modeling Language) class diagrams: animated replays, storyboards, iconic representations and a documentation method. These display mechanisms were implemented in a prototype UML editor. We present the results of an empirical interface refinement study that was conducted to determine the strengths and weaknesses of the four change display mechanisms. The results show some preference for the symbolic presentation of changes, specifically that most study participants liked the documentation method best. Qualitative result summaries are given for documentation and the other mechanisms.

    A Framework for Asynchronous Change Awareness in Collaboratively-Constructed Documents
    (2004-03-29) Tam, James; Greenberg, Saul
    Change awareness is the ability of individuals to track the asynchronous changes made to a collaborative document or surface by other participants over time. We develop a framework that articulates what change awareness in-formation is critical if people are to track and maintain change awareness. Information elements include: knowing who changed the artifact, what those changes involve, where changes occur, when changes were made, how things have changed, and why people made the changes. The framework also accounts for people�s need to view these changes from different perspectives: an artifact-based view, a person-based view, and a workspace-based view.

    GROUPLAB AT SKIGRAPH
    (2000-03-21) Boyle, Michael; Kaasten, Shaun; Rounding, Michael; Tam, James; Zanella, Ana; Greenberg, Saul; Carpendale, Sheelagh; Maurer, Frank
    The Western Computer Graphics Symposium, nicknamed 'SkiGraph', is an annual professional meeting comprising mostly graphics researchers and their graduate students from Western Canada. In 2000, several Western Canadian researchers in Human Computer Interaction: Saul Greenberg (U.Calgary), Carl Gutwin (U. Saskatchewan), Kori Inkpen (Simon Fraser) and Sheelagh Carpendale (U. Calgary) agreed to use Skigraph as a way to get themselves and their graduate students together, where students would present papers describing their research. Because it was important for all graduate students to share their ideas, the papers written could range from identification of research areas and tentative proposals of research problems all the way to detailed results from mature work. This research report collects five research papers by students at Grouplab to SkiGraph (Grouplab is the laboratory for human computer interaction research at the University of Calgary). The papers are listed below. In all cases, the students are the first author followed by faculty members who have supervised or contributed to the work in one way or another. Individual papers may be cited directly by including the following information.
