Area of Science:

  • Human-Computer Interaction
  • Educational Technology
  • Cognitive Science

Background:

  • Webcam-based eye tracking offers a practical method for observing reading behavior in educational settings.
  • Previous studies show feasibility in capturing reading dynamics, though data quality can be a challenge.
  • Accuracy can be comparable to infrared-based systems, despite potential limitations.

Purpose of the Study:

  • To assess the feasibility and accuracy of webcam-based eye tracking for monitoring comic book reading in a classroom.
  • To compare the performance of webcam-based eye tracking with infrared-based systems.

Main Methods:

  • A classroom experiment with 22 children reading a comic strip using webcam-based eye tracking.
  • Qualitative quality control to manage data loss.
  • Validation test with 3 participants comparing webcam and infrared systems for accuracy and precision.

Main Results:

  • Webcam eye tracking captured fixation dwell times, revealing faster reading on the left side of comics.
  • Webcam system accuracy was 11.581% (precision 3.058%), compared to infrared at 11.290% (precision 1.264%).
  • No significant difference in accuracy was found, though webcam precision was lower.

Conclusions:

  • Webcam-based eye tracking is a viable tool for studying reading behavior in classrooms.
  • Methodological enhancements are necessary to address data quality and precision limitations.
  • This technology provides insights into reading dynamics comparable to traditional methods.
