The most load-bearing concern is the absence of pairwise statistical tests for the central comparative claim, which the reader also noted in the rationale ('absence of pairwise statistical tests') but did not frame as the primary weakest assumption; the reader's stated weakest assumption focuses on unvalidated metrics and potential bias. I agree that the custom metrics are unvalidated, but the more fundamental issue is that even with perfect measurement, the reported analysis does not establish the specific pairwise superiority of AVP over Quest 3. This is an addressable reporting/analysis gap rather than a fundamental flaw, so CONDITIONAL remains the right verdict. The proposed concrete test would settle whether the claim survives; if the pairwise tests are non-significant, the paper would need to soften its conclusion or be rejected. Since the reader already conditionally accepted, my recommendation is unchanged.","tokens_in":4204,"tokens_out":2156,"duration_ms":18950,"concrete_test":"Obtain the participant-level data and perform pairwise post-hoc comparisons (e.g., Bonferroni-corrected Wilcoxon signed-rank tests) between AVP and Quest 3, and between AVP and Varjo XR-3, on each of the six pass-through quality metrics (CLA, RES, CA, DP, ENV, DIS).

The reader is left with means for AVP only; Quest 3 and Varjo means are not tabulated. An omnibus ANOVA only rejects the global null that all conditions are equal; with three headsets, the significance could be driven entirely by Varjo being much worse, while AVP and Quest 3 may be statistically indistinguishable. The abstract's comparative claim requires a significant pairwise contrast AVP > Quest 3, and that contrast is never reported. This is a load-bearing gap: even if the custom metrics are valid, the data as presented do not support the specific 'outperformed the Meta Quest 3' assertion. The unvalidated custom metrics (Section 2) add a second-order concern about whether the ratings measure what they claim, but the missing pairwise inference is more immediate and directly testable.","agreement_with_reader":"partial"},"referee_report":{"model":"deepseek-v4-flash","summary":"This manuscript reports a within-subjects user study (N = 31) comparing the pass-through quality of three mixed-reality headsets — Apple Vision Pro, Meta Quest 3, and Varjo XR-3 — plus a no-headset baseline condition, during two real-world tasks: reading a text aloud and solving a puzzle. Participants rated each condition on the NASA-TLX workload questionnaire, the CSQ-VR cybersickness questionnaire, and six custom pass-through quality metrics (clarity, resolution, color accuracy, depth perception, environmental awareness, distortion). The authors report that the Apple Vision Pro recorded the lowest task load and cybersickness scores and the highest pass-through quality ratings on all six dimensions, and they conclude that the Vision Pro outperformed the Quest 3 and Varjo XR-3. The central empirical claim is therefore that the Vision Pro delivers measurably better pass-through quality and user comfort than the other two headsets, with implications for applications in education, healthcare, and manufacturing.","tokens_in":4390,"tokens_out":7284,"duration_ms":55994,"significance":"The question is timely: comparative, task-based pass-through quality data on three current commercial headsets, including the recently released Apple Vision Pro, are scarce, and a controlled within-subjects study with ecologically plausible tasks is a useful contribution to the XR evaluation literature. The authors deserve credit for a clean study design — randomized condition order, a roughly gender-balanced sample (18 male, 13 female), validated instruments for workload (NASA-TLX) and cybersickness (CSQ-VR), and a controlled laboratory protocol with per-participant headset cleaning. If the comparative claim survives proper pairwise testing, the paper would give practitioners an actionable ranking of the three devices for pass-through-dependent applications. However, the headline claim is currently not backed by the statistics actually reported, so the paper's significance depends on the authors completing the inferential analysis rather than on the data as presented.","major_comments":[{"comment":"The central claim of the abstract — that the Apple Vision Pro 'outperformed the Meta Quest 3 and Varjo XR-3, receiving the highest ratings for pass-through quality' — is not supported by the statistics reported. The Pass-Through Quality paragraph gives means for the Vision Pro only (clarity M = 5.39, resolution M = 5.55, environmental awareness M = 5.58) and then states that 'Repeated-measures ANOVA for pass-through dimensions revealed significant differences as well,' without F statistics, effect sizes, means or standard deviations for the Quest 3 and Varjo XR-3, or any post-hoc tests. An omnibus ANOVA only rejects the global null; with three headsets, the significance could be driven entirely by Varjo's low scores while the Vision Pro and Quest 3 are statistically indistinguishable. The abstract's specific 'outperformed the Meta Quest 3' assertion requires a significant pairwise contrast, which is never reported. The authors should report full descriptive statistics for all six metrics and all three devices, and add pairwise post-hoc comparisons with correction for multiple comparisons (or nonparametric equivalents, given the ordinal rating scale).","section":"§3, Pass-Through Quality paragraph"},{"comment":"The Discussion draws comparative conclusions about all three devices — for example, that the Quest 3 'demonstrated a balanced performance' and that the Varjo XR-3 imposes 'higher cognitive demands' — but the Task Load and Cybersickness paragraphs report only omnibus ANOVAs (F(3,90) = 28.12 and F(3,90) = 16.11) with no post-hoc tests. For the reading task, the Vision Pro and Quest 3 means are very close (M = 18.84, SD = 8.66 versus M = 19.26, SD = 8.17), so without pairwise tests the claim that the Vision Pro has 'the lowest task load' relative to the Quest 3 is not established.

However, the abstract's comparative claim is exactly what other researchers will cite, so the editor should insist on full inferential reporting for the pass-through metrics before acceptance. If pairwise tests reveal that the Vision Pro does not significantly differ from the Quest 3 on the pass-through dimensions, the abstract and discussion will need to be rewritten accordingly.

But the central comparative claim in the abstract is not backed by the reported statistics; no pairwise post-hoc tests are given, so we don't know if AVP actually beats Quest 3 or just beats Varjo.\n\nThe concrete comparative data for AVP vs Quest 3 vs Varjo XR-3 is new; the tasks are ecologically reasonable; standardized questionnaires (NASA TLX, CSQ-VR) are used properly; within-subjects randomization to control order effects is good practice. That's real value for practitioners choosing a device.\n\nThe main statistical omission: Section 3 reports only omnibus ANOVAs. For pass-through quality, they only say 'significant differences' with no F stats at all. With three headsets, an omnibus effect can be driven by one outlier pair. The abstract's claim requires AVP > Quest 3, and that contrast is never reported. This is not a minor omission; it's the load-bearing inference. Also, the baseline (no headset) condition is mentioned in Methods but never reported in Results, so we can't anchor the workload/cybersickness numbers. The custom pass-through quality items are unvalidated — no item wording, no reliability, no factor analysis — so we don't know what 'clarity' etc. measure. These are fixable: add pairwise contrasts with corrections, report baseline means and SDs, and provide the questionnaire items and at least Cronbach's alpha. None of these are fatal to the study's descriptive value.\n\nWho it's for: HCI/XR practitioners and researchers wanting a first comparative data point on AVP pass-through. It deserves serious peer review, but only conditionally — the authors need to supply the missing inference and validation.
