Using Annotated Task Models for Accessibility Evaluation
Evaluation of application accessibility is a challenging task that requires an intensive testing with potential application users. An alternative to user tests is the model based testing using simulations. The simulations provide important feedback about application accessibility particularly when it is hard to involve the target users in the tests which is often the case for users with disabilities. In this paper we propose a methodology of providing the quickly and easily necessary data for the simulations. In particular we show how to annotate task models using application walkthroughs logs that is data obtained by recording the application usage. We create annotated task models, which together with the user models are suitable for simulation of application usage by virtual users with various disabilities. We present tools for recording and processing of the application walkthrough logs and tools for the interactive task model annotation. Finally, we provide actual examples of task model annotation on three scenarios involving the Second Life metaverse.
