a??SharedWella?? is a single display system that allows multiple users to interact with both private and public information in a face-to-face co-located setting. It is especially suited for strategic cooperative tasks which include both competitive and collaborative aspects. This type of collaboration, called strategic negotiations, requires users to perform three phases: identifying the right timing, using epistemic actions to draw attention, and evaluating the value of the negotiation. We conducted an observational study to investigate and evaluate deeper strategic negotiations on the SharedWell compared with other setups; a setup using notebooks and a real-world setup.
