MouseView.js offers a reliable, webcam-free alternative for online attention tracking in psychological research. This JavaScript tool mimics peripheral vision, providing valid data comparable to traditional eye tracking methods.

Area of Science:

  • Psychology
  • Human-Computer Interaction
  • Web-based Research

Background:

  • Online psychological research is expanding, necessitating tools for large-scale data collection.
  • Traditional eye tracking is difficult to implement online due to technical limitations.
  • Webcam-based eye tracking faces challenges with availability, image quality, and reflections.

Purpose of the Study:

  • To introduce MouseView.js as a viable alternative to eye tracking for web-based behavioral research.
  • To validate the reliability and accuracy of MouseView.js against established eye-tracking methods.
  • To provide an open-source tool for researchers to track attention in online studies.

Main Methods:

  • Developed MouseView.js, a JavaScript library that blurs the screen to simulate peripheral vision with a sharp focus aperture.
Keywords:
AttentionJavaScriptcyberpsychologyeye trackingonline experimentsopen-source

Related Experiment Videos

  • Validated MouseView.js through an online replication of a free viewing task and an in-lab comparison with eye tracking.
  • Collected data from 165 participants for the online replication and 50 participants for the in-lab comparison.

    • Main Results:

    • MouseView.js demonstrated reliability comparable to traditional eye gaze tracking.
    • The tool produced similar patterns of dwell time results as eye tracking.
    • Dwell time differences measured by MouseView.js and eye tracking showed high correlation and similar relationships with self-report measures.

    Conclusions:

    • MouseView.js is a reliable and valid tool for attention tracking in web-based psychological experiments.
    • The open-source JavaScript library can be integrated into existing research platforms like Gorilla and jsPsych.
    • MouseView.js offers a practical solution for researchers seeking to replace traditional eye tracking in online studies.
