Abstract:
Usability evaluation is not fundamental only in the interactive application development process, but also at operation time. In this paper, we discuss how a task model could be used to detect any incompleteness due to poor requirements when designing an interactive application. The focus is on the comparison between user task and user activity to detect deviations in order to mend the task model. It is about detecting unexpected situations and validating the task model as it brings many benefits (e.g., it represents a user documentation; it is used for training operators, etc.). Indeed, it aims to ensure the stability and effectiveness of the system when context change of the environment system occurs.
