TY - CONF AB - <p>Because heart rate lacks diagnosticity, an autonomic space approach for the assessment of mental workload has been proposed. In addition to increasing the capability to identify differences between tasks, the autonomic space approach can be used to make better inferences about the psychological processes involved. In this paper, the approach and its application to a simulated driving task are discussed, as well as suggestions for future research and its development.</p> AU - John K Lenneman, Vaughan W Backs DA - 2003/7// DO - 10.17077/drivingassessment.1106 IS - 2003 VL - 2 PB - University of Iowa PY - 2003 TI - The Evolution of Autonomic Space as a Method of Mental Workload Assessment for Driving T2 - Driving Assessment Conference UR - https://pubs.lib.uiowa.edu/driving/article/id/28123/ ER -
