| Abstract: | This research assessed whether a webcam-based eye tracker can measure mind-wandering. In the first part of the study, to test the feasibility of webcam-based eye tracking, an eye-tracking comparison study was conducted. 32 Participants pointed their gaze, while they were being monitored by a commercially available eye tracker and a webcam-based eye tracker. This part of the study revealed that the commercially available eye tracker was significantly more accurate than webcam-based eye tracking. Additionally, through the entire study, more gaze data was lost with the webcam-based eye tracker compared to the commercially available eye tracker. For the second part of the study, the goal was to capture the gaze behavior of participants. The participants performed a simple task, designed to provoke mind-wandering. Additionally, mind-wandering was measured using thought probes, which are short pop-up notifications that ask a participant about mind-wandering. This part of the study demonstrated that the commercially available eye tracker could capture differences in gaze behavior when participants’ minds wandered. Beyond this, the webcam-based eye tracker was able to capture differences in gaze behavior as well. Thus, this study showed that webcam-based eye tracking could be used to measure mind-wandering. However, data loss from this eye-tracking method was relatively high, which complicates the interpretation and implementation of webcambased eye-tracking. |
