A quantitative model of the human–machine interaction and multi-task performance: A strategy function and the unity model paradigm

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 ( B IN ) are generated by the multi-attribute task battery (MATB) and five HO baud r...

Description
Summary: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 ( B IN ) are generated by the multi-attribute task battery (MATB) and five HO baud rates ( B O ) are then recorded. Total baud ratio ( B ¯ ) is defined as the ratio of B O to B IN . Results indicate that with increasing B IN levels: (1) there is an overall increase in B O , and (2) there is an overall decrease in B ¯ . These results are due to a decreasing HMI performance and divergence of the strategy function from a unity model paradigm.
