As experienced over 2020 and 2021 globally, accessible data acquisition is vital for reaching representative populations. While adult online data acquisition has a longstanding basis, child online data acquisition has been limited, especially if unsupervised. Implicit measures of attention, such as those gathered via eye-tracking, can bolster our understanding of the processes underpinning efficient and accurate responses, but they have been tied to the lab or expensive equipment. Additionally, both adult and child webcam-based eye-tracking methods currently available have been difficult to calibrate. This has required re-calibration after a small number of trials thus prolonging study paradigms in a way that is counter-productive for children.
Finally, working with children can pose some variable limitations regarding ethics applications when using images or virtual safeguarding. Consequently, we developed and piloted a methodology in which the child can have virtual in-time interaction with the researcher in addition to gaze-tracking of specific tasks, providing direct feedback on the child’s attention, and reaction time and accuracy measures. Here, we will discuss ethical barriers and how we overcame them within our institution, as well as the methodology for online behavioural and webcam eye-tracking measures, in addition to pilot data.
