Understanding Context with ContextViewer - Tool for Visualization and Initial Preprocessing of Mobile Sensors Data

Mobile context-aware systems are becoming more and more popular due to the rapid evolution of personal mobile devices. The variety of sensors that are available on such devices allow building intelligent applications that adapt automatically to user preferences and needs. Together with a growth of such self-adaptable systems, number of tools for collecting, visualising and modelling context were developed. However, there is still a need for tools and methods that will support building mobile context-aware systems at the very early stage of development. Such solutions should provide mechanisms for collecting, visualising and initial preprocessing of data to allow better understanding of processes, patterns and dynamics of mobile contextual data. In this paper we propose ContextViewer– a toolkit that aims at providing such mechanisms. It is a part of a methodology for building context-aware systems that besides ContextViewer includes also modelling methods and runtime environment for executing models.
