This paper investigates the effects of the length of previewed target trajectory, or preview time, on HC behavior in rate tracking tasks. To do so, a human-in-the-loop experiment was performed, consisting of a combined target-tracking and disturbance-rejection task. Between conditions the preview time was varied between 0, 0.1, 0.25 0.5 0.75 or 1 s, capturing the complete human control-behavioral adaptation from zero- to full-preview tasks, where the performance remains constant. The measurements were analyzed by fitting a HC model for preview tracking tasks to the data. Results show that optimal performance is attained when the displayed preview time is higher than 0.5 s. When the preview time increases, subjects exhibit more phase lead in their target response dynamics. They respond to a single point on the target ahead when the preview time is below 0.5 s and generally to two different points when more preview is displayed. As the model tightly fits to the measurement data, its validity is extended to different preview times Subject Target Trackingmanual controlPreviewParameter EstimationHuman Factors To reference this document use: http://resolver.tudelft.nl/uuid:f43b6a7b-77c8-493c-ba3d-6137d8e6d587 DOI https://doi.org/10.1016/j.ifacol.2016.10.470 Publisher Elsevier, Laxenburg, Austria Source IFAC-PapersOnLine: 13th IFAC Symposium on Analysis, Design, and Evaluation of Human-Machine Systems HMS 2016, 49 - 19 Event 13th IFAC Symposium on Analysis, Design, and Evaluation of Human-Machine Systems, 2016-08-30 → 2016-09-02, Kyoto, Japan Part of collection Institutional Repository Document type conference paper Rights © 2016 K. van der El, S.
