Abstract

A human–machine-interaction (HMI) model is developed for the human operator (HO) performing five simultaneous tasks and characterized by a strategy function. Five levels of total machine-initiated baud rate Formula Not Shown are generated by the multi-attribute task battery (MATB) and five HO baud rates Formula Not Shown are then recorded. Total baud ratio Formula Not Shown is defined as the ratio of Formula Not Shown to Formula Not Shown . Results indicate that with increasing Formula Not Shown levels: (1) there is an overall increase in Formula Not Shown , and (2) there is an overall decrease in Formula Not Shown . These results are due to a decreasing HMI performance and divergence of the strategy function from a unity model paradigm.
