Abstract.As systems continue to grow in scale and complexity, human machine interactions and the human machine interface (HMI) become a crucial consideration in overall system design. In complex systems, humans are often part of the complex system as opposed to being just users of the system. The human mental model, work instructions, and procedures are key attributes that a system architect needs to analyze to ensure the success of the overall human-machine system. Model Based System Engineering (MBSE) techniques potentially offer new ways for system architects and engineers to conceptualize and analyze HMI requirements and use the findings to specify its design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
