An integrated logical context sensor for mobile web applications

Abstract

Context-aware computing continues to gain recognition, especially in mobile web computing. Determining accurate context information, in real-time, for implementing various adaptations in mobile web applications remains a challenge. Physically determined context information for use during adaptation has generally produced unsatisfactory results in mobile web applications. An alternative to acquiring context information is by the use of various software-based techniques that are referred to as logical context sensors. This paper discusses the implementation of an integrated logical context sensor that can determine context information in realtime for use in various mobile web adaptions.An international field study evaluation of the context sensor was conducted. Results indicate that the integrated logical context sensor successfully determined accurate context information in real-time. The logical context sensor discussed in this paper can be utilised by application developers to incorporate context-awareness in their applications.
