1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundWebcam-based eye tracking offers a practical approach for monitoring reading behavior in classroom environments. Nascimento et al. demonstrated the feasibility of using the Webcam-based eye tracking to observe comic reading patterns among children and showed that it effectively captures fixation time and reading dynamics. Despite the data quality challenges, Webcam-based eye tracking provided an accuracy comparable to that of infrared-based systems.

objectiveTo evaluate the feasibility and accuracy of webcam-based eye tracking for monitoring comic books reading behavior in a real-world classroom setting.

methodsWe tested the feasibility of using the webcam-based eye tracking in a children's classroom experiment (n=22), observing reading patterns as students engaged with a comic strip. Qualitative quality control was implemented to exclude low-quality data. Fixation dwell time was measured to determine whether specific areas of the image received more attention. Additionally, a validation test was conducted (n=3) to assess the accuracy and precision of webcam-based eye tracking compared with an infrared-based eye-tracking system. The accuracy and precision were evaluated, with lower values indicating better performance.

resultsDuring the comic reading task, webcam-based eye tracking effectively captured fixation dwell time, showing that students read the left side significantly faster (2.916 words/s, SD=0.705) compared to the right side (1.962 words/s, SD=0.450, p≤0.001). The validation test showed that webcam-based eye tracking had an average accuracy of 11.581% and a precision of 3.058%, whereas the infrared-based system recorded an accuracy of 11.290% and a precision of 1.264%. Although webcam-based eye tracking demonstrated a slightly lower precision (bias=-1.794, 95%CI=-3.055 to -0.532), no significant difference was observed in accuracy between the two systems.

background■ Webcam-based eye tracking demonstrated feasibility for monitoring reading behavior in classrooms.

background■ Webcam-based eye tracking captured fixation times, showing differing reading speeds across comic sections.

background■ Webcam-based eye tracking showed accuracy comparable to infrared-based systems, despite lower precision.

background■ Limitations resulting in data loss underscore the need for methodological improvements.
