Their security often cannot be fully automated for them, yet they generally lack both the motivation and technical knowledge to make informed security decisions on their own. To help users with this dilemma, we present a novel security user interface called Sesame. Sesame uses a concrete, spatial extension of the desktop

To help address this, we created WindowScape, a zooming window manager that uses implicit grouping to help users sort windows according to task. WindowScape was intended to provide a more flexible and intuitive grouping model than prior systems. We report on the design process leading up to the system, and alternative designs

Could tagging be sufficiently generic and lightweight to support diverse ways of working and, perhaps, support new and efficient practices for managing applications and accessing documents? We investigate these issues by implementing the TAGtivity system that enables users to tag resources in the context of their ongoing work. We deployed TAGtivity and studied users' tagging practices in their actual work places over a three week period. Our analysis of interviews and logs reveals that affordances of the TAGtivity system supported users in a variety of information and activity management tasks. These include new practices for managing emerging activities and ephemeral information and accessing documents across application data silos.

Most computer-based active reading support seeks to replicate the affordances of paper, but paper has limitations, being in many ways inflexible. In this paper we introduce LiquidText, a computer-based active reading system that takes a fundamentally different approach, offering a flexible, fluid document representation built on multitouch input, with a range of interaction techniques designed to facilitate the activities of active reading. We report here on our design for LiquidText, its interactions and gesture vocabulary, and our design process, including formative user evaluations which helped shape the final system.
