Towards the user confidence in sensor-rich interactive application environment

The recent advances in sensor-rich, ambient computing environmets have led to a situation in which ordinary users may express negative reactions when they feel that their behaviour is being monitored and analysed by technological systems which they do not understand. Cooking guide is an example application that is heavily depended on dynamic context information and adapts its behavior according to the context data. The VisuMonitor approach, described in this study, supports the users of Cooking Guide by providing visualization views that show the proceeding of cooking processes and also explains the functionality and behavior of the system during different cooking activities, thus improving user awareness, technology acceptance and user education. VisuMonitor utilizes semantic technologies in the modeling of workflows, which facilitates data integration and enables more efficient work progress monitoring and visualization. ACM Classification
