A Case Study on Quantifying the Workload of Working Machine Operators by Means of Psychophysiological Measurements
(English)Manuscript (preprint) (Other academic)
In this study of eighteen wheel loader operators, test-driving a machine in three different traction force settings, we examine if a workload index derived from psychophysiological measurements of heart rate, finger temperature, skin conductance, respiration rate and end-tidal CO2-concentration in exhaled air can be used to assess operator workload in sufficient detail to use it as a complement to traditional subjective evaluations, and also to use such measurements in a workload-adaptive operator assistance system in a longer perspective.
