“…We propose the use of ChordiAction, a collaborative user interface toolkit that can be used in various situations for co-located large-scale MT screens. According to Elliott and Hearst [3], larger multi-touch screens need novel interaction techniques in order for the users to interact in larger work-areas. Wall-sized larger displays can be used up close by several users at a time, they offer high resolution for working up close, and they provide sufficient space for varied collaboration styles [28].…”

Co-located collaboration on large vertical screens has become technically feasible, but users are faced with increased effort, or have to wear intrusive personal identifiers. Previous research on co-located collaboration has assumed that all users perform exactly the same task (e.g., moving and resizing photos), or that they negotiate individual actions in turns. However, there is limited user interface software that supports simultaneous performance of individual actions during shared tasks (Fig. 1a). As a remedy, we have introduced multi-touch chords (Fig. 1b) and personal action windows (Fig. 1c) for co-located collaboration on a large multi-touch vertical display. Instead of selecting an item in a fixed menu by reaching for it, users work simultaneously on shared tasks by means of personal action windows, which are triggered by multi-touch chords performed anywhere on the display. In order to evaluate the proposed technique with users, we introduced an experimental task, which stands for the group dynamics that emerge during shared tasks on a large display. A grounded theory analysis of users’ behaviour provided insights into established co-located collaboration topics, such as conflict resolution strategies and space negotiation. The main contribution of this work is the design and implementation of a novel seamless identification and interaction technique that supports diverse multi-touch interactions by multiple users: multi-touch chord interaction along with personal action windows.

“…affect coordination and awareness in tabletop tasks and proved that the choice of interaction technique does indeed matter, affecting coordination, performance and preference measures. Elliott and Hearst [3] proposed a touchsensitive interface should be used as a more appropriate interaction technique for larger interaction surfaces.…”

“…The working on large size displays also presents ergonomic issues such as reachability for users to desired artifact or contents. It forces users to stand-up for reaching up the artifacts to interact with [114]. The appropriate space for the user's feet under the table is very important in a sitting position.…”

With new computer technologies portable devices are rapidly approaching the dimensions and characteristics of traditional pen and paper-based tools. Text and graphic documents are now commonly viewed using small tablet computers. We conducted a study with small groups of participants to better understand how paper-based text and graphics are used by small collaborative groups as compared to how these groups make use of documents presented on a digital tablet with digital styluses. Our results indicate that digital tools, as compared to paper tools, can affect the levels of verbal communication and participant gaze engagement with other group members. Additionally, we observed how participants spatially arranged paper-based and digital tools during collaborative group activities, how often they switched from digital to paper, and how they still prefer paper overall.
