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 created on top of the principles of Reflect Table, a meeting support and analysis system centered on individuals’ participation and interactions.
