Collaborative Tangible Interface (CoTI) for Complex Decision Support Systems.

In this paper, we present CoTI, a Collaborative Tangible Interface to support decision making in complex systems. We start by describing the system architecture and the tangible interaction interface with an overview of design considerations for information architecture, navigation layers on multi-touch surfaces, and interaction modalities. A case study showcasing the CoTI in the context of urban planning is presented and design implications for city planning and co-located collaborative decision making is discussed.
