Abstract:
The usage of smart devices in combination with the extensive deployment of sensors enables the development of systems that can recognize their environment and act accordingly. These so-called context-aware systems allow the automation of the user interactions by providing the desired functionality based on an understanding of the users' current context. During the development of such systems, the context-related system properties, the contextual functionalities, as well as the underlying contexts must be defined. UML models are a valuable tool for such tasks. In this publication, the previous research regarding the graphical representation of context-aware systems is analysed. It is shown that the modelling of contextual behaviour is still not addressed sufficiently. To counter this issue, contextual design templates are introduced. These templates allow the visualization of different system properties by combining the UML standard notation with a newly introduced notation for statin
g contexts. Further, a profile for the modelling of contexts and related system functionalities is presented.
