Large Interactive Displays (LIDs), such as tabletops or interactive walls, are promising innovations, which are increasingly used to support co-located collaboration. Yet the current evidence base on the impact of LID use on collaborative processes and outcomes, and associated influencing factors, is fragmented, particularly in comparison with other media. To address this gap, a systematic review was carried out in the databases Web of Science, Psych.Info, ACM, Elsevier, JSTOR and Springer and in the ACM CHI conference database. A corpus of 38 articles with experimental study designs met the eligibility criteria and was analyzed in-depth. With regard to collaboration processes, the findings suggest a relatively clear advantage of the use of LIDs over classic forms of collaboration, in particular over single-user environments (e.g. laptops). With attention to collaborative outcomes, positive effects of LIDs were identified for knowledge gains and social encounters, and mixed effects for task-related outcomes. The analysis further shows relevant influencing factors of LID, such as the separation of personal and joint work spaces and the deployment of horizontal instead of vertical displays. Conceptual and practice implications are discussed.

Agile methods emphasize highly interactive and close collaboration within teams and among stakeholders. Due to still missing adequate digital tools, agile teams use mostly physical artefacts like wallboards and story cards. In this paper, we present aWall, an agile team collaboration tool for large multi-touch wall systems. aWall was designed based on empirical user research using new interaction and visualization concepts to support and foster the highly collaborative and communicative agile work style. The application is based on web technology and can be used in both co-located and distributed setting. The implemented prototypes were validated with end-users in a user workshop. In the demo, users can experience the interaction and visualization concepts hands-on.
