however, it remains unclear how such motion control interacts with WebGazer.js estimates of event detection and onset latency.
Great - maybe a sentence after this to highlight the importance of what the chin rest does for stabilization. "In laboratory-based eye-tracking, chin rests are routinely used to stabilize the head in a fixed position so that only the eyes move during the experiment."
in the version most relevant to the present study
maybe for clarity: "..the VWP paradigm used in this study will introduce phonemic competition." Then talk about the four pictures and trial types. Maybe also add in something about the specific effects expected to be observed in this paradigm (e.g., large cohort effect, smaller rhyme effect, no competition with unrelated items) as has been previously shown.
To address this, participants will complete the same VWP task using one of two webcam types:
just realized maybe get in earlier in the paper whether this is between subjects or within subjects design.
As noted above

This design allows us to isolate the causal effects of hardware and movement on data quality.
Since there are likely many factors that we won't control in this design that could affect outcome, I might stay away from the "causal" language here. Recommendation: "This design allows us to identify how hardware selection and participant stability impact data quality."
high- vs. standard-quality external cameras
maybe just clarify here - High quality option - is that an internal camera or external? Are they both external cameras and one is just poorer quality or is one the built-in camera?
and, crucially, whether future improvements can mitigate these issues.
clarify to: "and, crucially, whether future improvements in the set up of webcam eye-tracking can mitigate these issues."
standard webcamera
computer cameras
Together, these studies isolate the causal influence of hardware and movement on webcam eye-tracking data quality
Maybe a bit less committal: "Together, these studies identify the impact of hardware and movement on webcam eye-tracking data quality."
bringing webcam eye-tracking back into a controlled laboratory setting
maybe update this sentence: "The present registered report directly tests two factors that may introduce noise into webcam data: camera quality and head stabilization.
higher-quality webcams
maybe clarifying here - these would be external cameras correct? Not the built in camera that is typically used
Bringing Sexy (Webcam Eye-tracking) Back into the Lab: Stage 1 Registered Report
For clarity, I think we should simplify the title to reflect the study more clearly. What about something like "Improving Webcam Eye-Tracking: Impact of Hardware and Stabilization on Data Quality"
