Designing a search system and interface may best be served (and executed) by scrutinizing usability studies.
We have developed an innovative search interface that allows non-expert users to move through large information spaces in a flexible manner without feeling lost. The design goal was to offer users a " browsing the shelves " experience seamlessly integrated with focused search. Key to achieving our goal is the explicit exposure of hierarchical faceted… (More)
One of the most pressing usability issues in the design of large web sites is that of the organization of search results. A previous study on a moderate-sized web site indicated that users understood and preferred dynamically organized faceted metadata over standard search. We are now examining how to scale this approach to very large collections, since it… (More)

The authors present a concept for an anti-tamper system that dynamically generates a cryptographic key derived from microelectromechanical systems (MEMS) arrays encapsulated within a protected system in a single package. The system provides protection in active and passive states with no battery backup.
