Tangible interfaces for remote collaboration and communication

Current systems for real-time distributed CSCW are largely rooted in traditional GUI-based groupware and voice/video conferencing methodologies. In these approaches, interactions are limited to visual and auditory media, and shared environments are confined to the digital world. This paper presents a new approach to enhance remote collaboration and communication, based on the idea of Tangible Interfaces, which places a greater emphasis on touch and physicality. The approach is grounded in a concept called Synchronized Distributed Physical Objects, which employs telemanipulation technology to create the illusion that distant users are interacting with shared physical objects. We describe two applications of this approach: PSyBench, a physical shared workspace, and inTouch, a device for haptic interpersonal communication.
