Requirements engineering for interactive systems remains a cumbersome task still under-supported by development processes. Indeed, in the field of HCI, currently 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 design, promote a design process based on the analysis of the actual use of a technology in order to design new technologies better supporting users’ tasks. However, these approaches do not provide any support for a) the definition of a set of requirements that have to be fulfilled by the system under design and b) as a consequence for assessing which of these requirements are embedded in the system and which ones have been discarded. This position paper proposes a notation and a tool for addressing precisely these two challenges. These elements are integrated within a more global approach aiming at providing notations and tools for supporting a rationalized design of interactive systems following a model-based approach.
