COLET: A Dataset for Cognitive WorkLoad Estimation Based on Eye-Tracking
13 Pages Posted: 21 Mar 2022
The cognitive workload is an important component in performance psychology, ergonomics, and human factors. Unfortunately, publicly available datasets are scarce, making it difficult to establish new approaches and comparative studies. In this work, COLET-COgnitive workLoad estimation based on Eye-Tracking dataset is presented. Forty-seven (47) individuals' eye movements were monitored as they solved puzzles involving visual search tasks of varying complexity and duration. The authors give an in-depth study of the participants' performance during the experiments while eye and gaze features were derived from low-level eye recorded metrics, and their relationships with the experiment tasks were investigated. The results from the classification of cognitive workload levels solely based on eye data, by employing and testing a set of machine learning algorithms are also provided. The dataset is available to the academic community.
