A Comparison of Cooperative and Competitive Visualizations
Decades of research suggest that cooperation leads to greater productivity than competition. However, most of the existing group mirror visualizations achieve an increase in productivity and better self-regulation by enabling a direct comparison of performance within the group. We present a study that investigates the influence of different types of visualizations on collaboration. The visualizations present the group’s performance either in a more cooperative or more competitive way. Results indicate that groups that see a combination of individual and group performance(mixed condition) are more productive, more satisfied with their results and participate in a more balanced way.

Supporting the Disney Method II
The Disney method is a collaborative creativity technique that uses three roles - dreamer, realist and critic - to facilitate the consideration of differ-ent perspectives on a topic. Especially for novices it is important to obtain guid-ance in applying this method. One way is providing groups with a trained mod-erator. However, feedback about the group’s behavior might interrupt the flow of the idea finding process. We built and evaluated a system that provides am-bient feedback to a group about the distribution of their statements among the three roles. Our preliminary field study indicates that groups supported by the system contribute more and roles are used in a more balanced way while the visualization does not disrupt the group work.

Supporting the Disney Method I
We developed an interactive system supporting groups using the Disney Method. Each group member is provided with a tablet to enter ideas and choose the role in which a contribution is made, represented by different colors. We conducted a user study with eight groups and compared two versions: a baseline without additional support and a version with an additional feedback mechanism providing functional feedback about the distribution of the roles. Our main contributions are: (1) a system using feedback to support the Disney method and (2) results indicating that functional feedback can help modest group members to engage more in the group process.

Supporting Debates with a Group Mirror
We investigate a novel real-time feedback system that enables a subtle and unobtrusive interaction between learners and trainers in the context of debates. Novices to structured debates practiced in debate clubs need to learn fundamental rhetorical skills. The argumentation follows a well-defined structure: claim, explanation and example. Learners receive feedback about their rhetorical performance in the end of debates which complicates the immediate adaptation. We introduce a real-time feedback system enabling an unobtrusive teacher-student dialog. Teachers virtually communicate their assessment about the presented performance using a smart phone; students adapt the structure of their debate according to the visual feedback that is presented on a tablet.

Groupgarden
We present Groupgarden, a metaphorical group mirror providing feedback about individual as well as group performance. We conducted two user studies. We could validate the effectivity of Groupgarden in a preliminary study that compared brainstorming sessions supported by Groupgarden with sessions without additional support. In a second study, we examined the influence of the location of the feedback, wall vs. table, on group behavior. Our results indicate that the location does not influence efficiency of brainstorming, while each location has different benefits.
