Context-aware notification for mobile police officers

Abstract

To minimize unwanted interruption and information overload during surveillance, mobile police officers need to be supported by a mobile, contextaware notification system. This system adapts message presentation to message priority and context of use. A prototype is designed and evaluated in a simulated surveillance task, requiring users to attend to videos while handling messages on a mobile device. Adaptive notification led to better performance and less intrusive messages than non-adaptive notification, especially in high workload situations. Subjective judgments showed a positive user experience with the adaptive notification system. These empirical findings are used to improve the design of mobile notification support systems for police officers. © Springer-Verlag Berlin Heidelberg 2007.
