Zusammenfassung
Task models are a very powerful artefact describing users’ goals and users’ activities and contain numerous information extremely useful for designing usable interactive applications. Indeed, task models is one of the very few means for ensuring effectiveness of the application i. e. that the application allows users to reach their goals and perform their tasks. This paper presents a tool-supported framework for exploiting task models throughout the development process and even when the interactive application is deployed and used. To this end, we introduce a framework for connecting task models to an existing, executable, interactive application. The main contribution of the paper lies in the definition of a systematic correspondence between the user interface elements of the interactive application and the low level tasks in the task model. Depending on the fact that the code of the application is available or not, the fact that the application has been prepared at programming time for such integration or not, we propose different alternatives to perform such correspondence (in a toolsupported way). This task-application integration allows the exploitation of task models at run time bringing in the benefits listed above to any interactive application. The approach, the tools and the integration are presented on a case study of a Flight Control Unit (FCU) used in aircraft cockpits. This paper extends the article entitled ‘A Generic Tool-Supported Framework for Coupling Task Models and Interactive Applications’ which have been presented at the 7 ACM SIGCHI Symposium on Engineering Interactive Computing Systems (EICS 2015). In this expanded version, the detailed description of the correspondence between annotations in the program of the interactive application and interactive tasks in the task models has been added. The complete version of the case study has also been integrated so that the application of each step of the proposed validation process is presented.
