ABSTRACT
As the concept of context-awareness is becoming more popular the demand for improved quality of context-aware systems increases too. Due to the inherent challenges posed by context-awareness, it is harder to predict what the behavior of the systems and their context will be once provided to the end-user than is the case for non-context-aware systems. A domain where such upfront knowledge is highly important is that of well-being. In this paper, we introduce a method to model the well-being domain and to predict the effects the system will have on its context when implemented. This analysis can be performed at design time. Using these predictions, the design can be fine-tuned to increase the chance that systems will have the desired effect. The method has been tested using three existing well-being applications. For these applications, domain models were created in the Dynamic Well-being Domain Model language. This language allows for causal reasoning over the application domain. The models created were used to perform the analysis and behavior prediction. The analysis results were compared to existing application end-user evaluation studies. Results showed that our analysis could accurately predict success and possible problems in the focus of the systems, although certain limitation regarding the predictions should be kept into consideration.

Mentions: When working on the development of software systems, we are concerned with structural aspects, that is, which components can be recognized and how are they related, and behavioral aspects, that is, how will the system react to situations. In the well-being domain, we can recognize similar constructs. To capture both structural and behavioral aspects of the well-being domain, we have created a Domain Specific Language (DSL). Capturing both these context aspects is not possible with current general purpose modeling languages. This DSL was inspired by the Causal Loop Diagram (CLD) notation introduced by Sterman [24]. Where CLDs only provide for notations regarding variables and causal relations between them, we have added properties required to deal with context-awareness and well-being system development. Figure 2 depicts the structure of DWDMs using a small example. This example illustrates the effects of physical activity on cardiovascular fitness and on the resting heart rate.
