Webcam-Based Online Eye-Tracking for Behavioral Research
Based on the understanding of the “eye-mind hypothesis,” neuroscientists have been utilizing eye-tracking software in their lab settings to collect data for various behavioral studies (more specifically, attention studies). But, with the rapidly changing state of scientific research there has been recent interest in bringing eye-tracking software to an online-based platform. Doing so would unlock new levels of participant accessibility while simultaneously improving data collection methods and programming capabilities of such software.

In their publication, Yang and Krajbich shared the results of their study where it was concluded this online-based eye-tracking software had promise for behavioral research. While there are still obstacles to be overcome (such as attrition and exclusion criteria), this project showed the flexibility in the programming of softwares like WebGazer. These results add evidence that eye-tracking through online webcams is a likely future feature for behavioral neuroscience.
