Customizing Mobile Applications

摘要

The dynamics of mobile systems require applications to intelligently adapt to changes in system configurations and to their environment. The authors describe a workplace in which users interact with a number of stationary and mobile systems through the course of a day. The relationship between systems and devices is constantly changing due to user mobility. They present a facility for mobile application customization called 'dynamic environment variables.' The facility allows flexible sharing of customization contexts, supports short interactions with long term services, and provides efficient notification of environment changes to applications. A sample application built in PARC's mobile computing environment and initial performance evaluations are described. (Copyright (c) Copyright 1993 Xerox Corporation.)
