The interactive workspaces project explores new possibilities for people working together in technology-rich spaces. The project focuses on augmenting a dedicated meeting space with large displays, wireless or multimodal devices, and seamless mobile appliance integration. The authors constructed several versions of their prototype interactive workspace, called the iRoom, created a software infrastructure for this environment, called iROS, and conducted experiments in human-computer interaction in the workspace. They also assisted outside groups in using their technology to construct application suites that address problems in their own domains, and they deployed our software in production environments.
