Invited talk: A model and simulation for user-centric automation devices and systems

Summary form only given. This talk will present an environment and an executable model that support simulation of user-centric automation devices and systems (UCADS), human users and user-device interactions. The underlying UCADS combines workflow and GOMS model elements. The combination makes it possible to leverage GOMS interface evaluation techniques in experimentation with deviceuser interactions and assessment of actions and behavior of different human user(s) under different operating conditions, while applying workflow technologies to specify device operations and user-device interactions formally in a coherent, easy-to-understand way. The model and UCADS simulation environment enable experimentation with and the evaluation of device prototypes and their interactions with diverse, multiple users, for the purpose of identifying design and implementation flaws in a new device (or system) and assessing the degree to which the device is usable and safe.
