Task analysis can be considered as a fundamental component of user centered design methods as it provides a unique way of analyzing in a systematic way users' roles and activities. A widely used way of storing the information gathered during that phase in a structured and exhaustive way is to build task models which are then amenable to verification of(More)
Along tasks analysis and modeling history it has been demonstrated by experience that task modeling activities become cumbersome when performed on large, real-life systems. However, one of the main goals of task models is to provide designers with a structured and complete description of the users tasks especially when these user tasks are numerous and/or(More)
Operation of safety critical systems requires qualified operators that have detailed knowledge about the system they are using and how it should be used. Instructional Design and Technology intends to analyze, design, implement, evaluate, maintain and manage training programs. Among the many methods and processes that are currently in use, the first one to(More)
A BST R A C T Requirements engineering for interactive systems remains a cumbersome task still under-supported by notations, development processes and tools. Indeed, in the field of HCI, the most common practice is to perform user testing to assess the compatibility between the designed system and its intended user. Other approaches such as scenario-based(More)
Designing systems in such a way that as much functions as possible are automated has been the driving direction of research and engineering both in aviation and in computer science for many years. In the 80’s many studies (e.g. [1] and [8] related to the notion of mode confusion) have demonstrated that fully automated systems are out of the grasp of current(More)
The work presented in this paper is based on a synergistic approach [1] integrating models of operators' tasks (described using the HAMSTERS notation) with models of the interactive system (described using the ICO notation) they are using. This synergistic approach makes it possible to bring together two usually independent (but complementary)(More)
While a significant effort is being undertaken by the HumanComputer Interaction community in order to extend current knowledge about how users interact with computing devices and how to design and evaluate new interaction techniques, very little has been done to improve the reliability of software offering such interaction techniques. However, malfunctions(More)
