Abstract

This study aimed to identify real-life experts working for a
port authority and lay people (students) who played The Sustainable
Port, a serious game aiming to simulate the dynamics occurring in a
port area. To achieve this goal, we analyzed eye gaze data collected non
invasively using low-grade webcams from 28 participants working for the
port authority of the Port of Rotterdam and 66 students. Such data were
used for a classification task implemented using a MiniRocket classifier,
an algorithm used for time-series classification. The classifier reached an
F1 score of 0.75 (SD = 0.07), a PR AUC of 0.73 (SD = 0.14), and an ROC
AUCof0.75 (SD = 0.15) providing evidence that it is possible to identify
real-life experts about maritime port management using data that can
be obtained from a webcam. We speculate that the gaze direction used
to train the MiniRocket may contain relevant information about the
cognitive processes and decisions occurring throughout the gameplay.
We suggest that the methods here presented not only can be used to
detect experts playing simulations, such as serious games, but also to
identify experts tackling screen-presented tasks.
