• Abstract:
  In this study, subjects in a driving simulator followed a lead vehicle that continuously changed speed ; while they also performed a secondary task on a touch-screen monitor that could be located at various ; positions within the simulator. Subjects were instructed to give priority to the following task. Driving ; performance in the following task was affected by whether or not the secondary task was required, but ; was not affected by the location of the monitor. However, consistent with the instructions about priority ; of tasks, time to complete the secondary task was strongly influenced by monitor position. Farther ; locations required more time, especially for shorter subjects. Analysis of the number and timing of ; glances away from the road suggested that subjects coped with the more difficult monitor positions ; primarily by making more glances to the monitor, while the average duration of individual glances was ; not much affected. These results suggest that the subjects’ partial success in coping with the secondary ; task was possible because the secondary task could be broken down into partially independent subtasks. ; This study was part of a modeling effort designed to better understand the combined visual and motor ; demands of secondary tasks, and how they are affected by the design of controls and displays. Various ; ways in which this study should be extended to support that modeling effort are reviewed.
