New user interface challenges are arising because people need to explore and perform many diverse tasks involving large quantities of abstract information. Visualizing information is one approach to these challenges. But visualization must involve much more than just enabling people to "see" information. People must also manipulate it to focus on what is(More)
Visage is a prototype user interface environment for exploring and analyzing information. It represents an approach to coordinating multiple visualizations, analysis and presentation tools in data-intensive domains. Visage is based on an Information-centric approach to user interface design which strives to eliminate impediments to direct user access to(More)

This paper describes a pervasive, scalable, and extensible design for distributed information objects. The system is designed so that all information has persistent identity, independently of the devices used to store and transmit information. The system relies on the notion of a u-form, which is a bundle of attribute-value pairs indexed by a universal(More)
The Visage prototype responds to data-intensive work environments where users, exploring and analyzing data, struggle to make useful multiple applications with disparate visualizations of potentially related information. Visage seeks to coordinate the exploration, analyses, and visualizations of information regardless of their source or type. This(More)
Advances in location aware computing and the convergence of geographic and textual information systems will require a comprehensive, extensible, information rich framework called the Information Commons Gazetteer, that can be freely disseminated to small devices in a modular fashion. This paper describes the infrastructure and datasets used to create such a(More)
Shared mutable information objects called u-forms provide an attractive foundation on which to build collaborative systems. As we scale up such systems from small fully-connected workgroups to large, highly distributed, and partially disconnected groups, we have found that peer-to-peer technology and optimistic replication strategies provide a(More)
Civium is a global public information commons that aspires to unite the world's basic factual information in a radically distributed peer-to-peer network, based on a structure entirely different from the Web's. It is a seamless fabric of hard facts-accessed via a novel mapping interface known as the Civium Geobrowser-embroidered with constantly expanding(More)
