Abstract
Computers support more and more daily activities for common
users, and users increasingly take their activities to different locations.
Rather than being bound to a specific device, users may like to take full
advantage of the computer systems accessible to them, much like they take
advantage of the furniture in each physical space. However, user attention takes a heavy toll
when scaling the use of computers to tasks that are constantly interrupted
and resumed, and that span many locations and long periods. In this report we describe an
infrastructure that provides users with easy access to their tasks as a
logical unit, across multiple devices, and over time spans of years. The infrastructure handles platform and
application heterogeneity, as well as dynamic adaptation to resource
variations. We validate that the
infrastructure’s overhead is small compared to normal application
startup, and that the approach scales.
