    Bridging private and shared interaction surfaces in co-located group settings
    (ACM, 2012) Scott, Stacey; McClelland, Phillip; Besacier, Guillaume
    This work-in-progress paper describes the design of an interaction technique that addresses user interaction challenges with digital object transfer between private and shared surfaces, particularly in co-located group settings. We propose a transfer technique for bridging tablets and digital tables that builds on existing interaction techniques, such as virtual embodiments and multi-display bridging techniques, to improve awareness of the transfer process both for the person performing the transfer and for their collaborators. The technique also minimizes effort involved in the transfer action, enabling people to focus on the activity at hand--or the ongoing conversation--rather than on the technologies being used.

    How People Partition Workspaces in Single Display Groupware
    (2003-10-27) Tse, Edward; Histon, Jonathan; Scott, Stacey; Greenberg, Saul
    Single Display Groupware (SDG) lets multiple people, each with their own input device, interact simultaneously on a single display. With two or more people potentially working in the same or nearby areas of the display, the actions of one could interfere with others, e.g., by raising menus and bringing tool palettes into areas where others are working. Interaction techniques could be used to mitigate the interference; however, other approaches might be more suitable if collaborators were to naturally partition their workspace into distinct areas when working on a particular task. To determine the realistic potential for interference, we investigated people performing a set of collaborative drawing exercises in a co-located setting, paying particular attention to the locations of their interactions in the shared workspace. We saw that spatial division occurred consistently and naturally accross all participants, rarely requiring any verbal negotiation. Particular divisions of the space varied, influenced by seating position and image semantics. These results have several implications for the design of SDG workspaces, including the consideration of peoples' seating positions at the display, the use of moveable Local Tools and in-context menus, and the use of dynamic transparency to mitigate interference.

    Investigating menu discoverability on a digital tabletop in a public setting
    (ACM, 2012) Seto, Mindy; Scott, Stacey; Hancock, Mark
    A common challenge to the design of digital tabletops for public settings is how to effectively invite and guide passersby--who often have no prior experience with such technology--to interact using unfamiliar interaction methods and interfaces. We characterize such enticement from the system interface as the system's discoverability. A particular challenge to modern surface interfaces is the discoverability of system functionality: does the system require gestures? are there system menus? if so, how are they invoked? This research focuses on the discoverability of system menus on digital tabletops designed for public settings. An observational study of menu invocation methods in a museum setting is reported. Study findings suggest that discernible and recognizable interface elements, such as buttons, supported by the use of animation, can effectively attract and guide the discovery of menus. Design recommendations for improving menu discoverability are also presented.

    Revisiting hovering: interaction guides for interactive surfaces
    (ACM, 2012) Cheung, Victor; Heydekorn, Jens; Scott, Stacey; Dachselt, Raimund
    Current touch-based interactive surfaces rely heavily on a trial-and-error approach for guiding users through the interaction process. In contrast, the legacy WIMP (Windows, Icons, Menus, Pointer) paradigm employs various methods to provide user assistance. A commonly used strategy is the use of mouse hovering. This research explores how this strategy can be adapted and expanded to user interaction with interactive surfaces to provide user assistance as well as to help address common surface interaction issues, such as precisions. Design dimensions and considerations are discussed, and potential hover interaction techniques are proposed. These techniques emphasize the use of animation to facilitate user engagement and improve the overall user experience.

    Storage Bins: Mobile Storage for Collaborative Tabletop Displays
    (2004-12-23) Scott, Stacey; Carpendale, Sheelagh; Habelski, Stefan
    Casual piling of paper-based media during traditional tabletop collaboration is an important practice that helps coordinate task and group interactions. Previous research has shown that the ability to move piles around on a table plays a critical role in accessing and sharing task resources. However existing casual storage techniques for digital workspaces only provide access to stored items at the periphery of the workspace, potentially compromising collaborative interactions at a digital tabletop display. To address this issue, we introduce storage bins, a mobile storage mechanism that enables access to stored items anywhere in the workspace. We also

    System Guidelines for Co-located, Collaborative Work on a Tabletop Display
    (2003-04-14) Scott, Stacey; Grant, Karen; Mandryk, Regan
    Collaborative interactions with many existing digital tabletop systems lack the fluidity of collaborating around a table using traditional media. This paper presents a critical analysis of the current state-of-the-art in digital tabletop systems research, targeted at discovering how user requirements for collaboration are currently being met and uncovering areas requiring development. By considering research on tabletop displays, collaboration, and communication, several design guidelines for effective co-located collaboration around a tabletop display emerged. These guidelines suggest that technology must support: (1) natural interpersonal interaction, (2) transitions between activities, (3) transitions between personal and group work, (4) transitions between tabletop collaboration and external work, (5) the use of physical objects, (6) accessing shared physical and digital objects, (7) flexible user arrangements, and (8) simultaneous user interactions. The critical analysis revealed several important directions for future research, including: standardization of methods to evaluate co-located collaboration; comparative studies to determine the impact of existing system configurations on collaboration: and creation of a taxonomy of collaborative tasks to help determine which tasks and activities are suitable for tabletop collaboration.
