In this paper we present the motivation, design, development, and initial evaluation of a time awareness technology for meetings. As part of improving meetings effectiveness using technology, we focus on the meeting time management, and the method relies on presenting real-time notifications of the progression of the meeting phases to the participants. We then evaluate the utility of the technology, and its impact on the people and their behavior in the meeting, concluding that such a support sy...

In co-located meetings, participants create and share content to establish a common understanding. In this paper, we present a collaborative environment that enables group members to create and share content simultaneously by providing them with different kinds of individual input devices and a shared workspace. We also report on an exploratory study to investigate the influence of the input device used on the shared knowledge produced by the group. The results suggest that driven by the afforda...

We present the results of group dynamics and their effect on success in problem solving/decision making meetings. We use a novel multiple input environment for collaboration and data collection, and a hidden profile task given to groups, whose goals are to find the correct solution. We observe that groups elect 0, 1 or 2 leaders, and the best results are obtained by the groups with a single leader. Prior acquaintance (familiarity), does not show any effect on the success or on the group strategi...

We present a longitudinal study on the participation regulation effects in the presence of a speech aware interactive table. This study focuses on training meetings of groups of top level managers, whose compositions do not change, in a corporate organization. We show that an effect of balancing participation develops over time. We also report other emerging group-specific features such as interaction patterns and signatures, leadership effects, and behavioral changes between meetings. Finally w...

In this paper, we describe the efforts in taking advantage of the latest IT developments, (especially of the development of mobile computing devices such as tablets or phones) to create a comprehensive architecture for face-to-face meetings support and groups evolution analysis. The main purpose of the architecture is to mitigate frequent meetings problems by providing state-of-the-art technological support to groups or teams. This paper introduces ReflectWorld, the distributed architecture crea...

In co-located meetings, content creation is often distributed among the group members and sharing requires transfer of content artifacts, which impedes collaboration. In this paper, we present the design of a collaborative environment to support this activity in meetings for small groups. The system consists of a shared wall-mounted workspace where users can interact using either mouse and keyboard or digital pen and paper. We also present a user study comparing the two input configurations and ...
