Interactive workspaces are increasingly physically distributed, highlighting the challenge of building interfaces that support group interaction with digital documents through multiple locations and devices. This paper presents the technical implementation and user interface of  ReticularSpaces . Based on the concepts and principles of Activity-Based Computing (ABC),  ReticularSpaces  implements a novel approach to smart space user interfaces, and supports task-based information management, mobility, and collaboration.
