- ItemMetadata onlyInteractive Surface Technology for a Mobile Command Centre(ACM, 2011) Cheung, Victor; Cheaib, Nader; Scott, Stacey D.In this paper, Contextual Inquiry is used to analyze the work inside a mobile command centre of a volunteer group, which provides specialized services and equipment to support events ranging from community-sponsored events to emergency incidents. The suitability and feasibility of utilizing interactive surface technology to support collaboration and coordination, using the mobile command centre as a hub for multiple agencies, are examined. Findings and lessons learned from this work can also inform the design of such technology for more general event organization and emergency response settings.
- ItemMetadata onlyInvestigating attraction and engagement of animation on large interactive walls in public settings(ACM, 2013) Cheung, Victor; Scott, Stacey D.Large interactive walls capable of delivering dynamic content to broad audiences are becoming increasingly common in public areas for information dissemination, advertising, and entertainment purposes. A major design challenge for these systems is to entice and engage passersby to interact with the system, and in a manner intended by the designers. To address this issue, we are examining the use of different types of animation at various stages of the interaction as someone approaches and begins interacting with the system. Using usage measures from museum studies, namely, attraction and engagement of an exhibit, we plan to assess the effectiveness of different types of animation in the context of an interactive notice board application in a university campus. We describe our design approach and plans for studying the animation design in a real-world public setting.
- ItemMetadata onlyRevisiting hovering: interaction guides for interactive surfaces(ACM, 2012) Cheung, Victor; Heydekorn, Jens; Scott, Stacey; Dachselt, RaimundCurrent 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.
