    THE e-TABLE: EXPLORING COLLABORATIVE INTERACTION ON A HORIZONTAL DISPLAY
    (2002-12-18) Kruger, Russell; Carpendale, Sheelagh
    The e-Table is a table with an embedded LCD display. Research on the e-Table is novel; there remains a lack of published work on two-dimensional horizontal displays. As such, this research has involved investigating the design space of a table display; that is, the unique characteristics and potential utility of a table display. To this end, an observational study was carried out involving participants completing puzzles on a regular table, a table display and an upright display. An initial analysis of these sessions has been performed, and qualitative observations relating to distinctive qualities of a table display have been made.

    Exploring Orientation on a Table Display
    (2003-08-18) Kruger, Russell; Carpendale, Sheelagh
    With the recent move towards table displays, there has been an increasing interest in examining horizontal orientation. In order to effectively understand this issue, it is important to have a foundational understanding of orientation on physical tables as well as table dependent aspects of orientation. As an initial investigation into supporting rotation of digital objects on table displays, an examination of mobile controls was carried out. A test application consisting of a map with labels that could be freely rotated was implemented and examined, and from this a general framework for approaching orientation on table displays emerged.

    Fluid Orientation on a Tabletop Display: Integrating Rotation and Translation
    (2004-05-04) Kruger, Russell; Carpendale, Sheelagh; Tang, Tony; Scott, Stacy
    Previous research has shown that rotation and orientation of items plays three major roles during the course of tabletop collaboration: comprehension, coordination and communication. Based on these roles of orientation, we designed a novel tabletop rotation mechanism, Rotate N Translate (RNT), which provides integral control of rotation and translation using only a single touch-point for input. We present an empirical evaluation comparing RNT to the standard rotation mechanism that separated control of rotation and translation. Results of this study indicate RNT is more efficient than the separate mechanism and better supports the communicative and comprehensive roles of orientation, without sacrificing support for coordination.

    Fluid orientation on tabletop displays: supporting co-located collaboration
    (2004) Kruger, Russell; Carpendale, Sheelagh
    Tabletop displays represent one new technology intended to support face-to-face collaboration. An issue of particular importance for tabletop displays is orientation: since individuals may sit at different sides of the display, collaborators do not necessarily share a common view of the workspace. To investigate the role of orientation in tabletop collaboration, I present an observational study of collaboration over a traditional table. An analysis of this study reveals three major roles that orientation plays in tabletop collaboration: comprehension, coordination, and communication. Based on these roles of orientation, I present a fluid tabletop rotation technique, Rotate 'N Translate (RNT), that provides integral control of rotation and translation using a single touch-point for input. Lastly, I present an evaluation comparing RNT to the standard technique that separates control of rotation and translation. Results of this study indicate RNT better supports the communicative and comprehensive roles of orientation, without sacrificing support for coordination.
