The pith
PicoEyes predicts 3D eye parameters, axes, segmentation and depth maps from monocular or binocular inputs in a single end-to-end network.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
PicoEyes jointly estimates 3D eye parameters and depth maps from monocular or binocular near-eye images in an end-to-end network, enabling simultaneous gaze prediction, calibration handling, forecasting, and reconstruction on a new large-scale multi-view dataset that covers diverse device postures and session types.
What carries the argument
End-to-end network that predicts 3D eye parameters together with eye-region segmentation, optical axis, visual axis, and depth maps from either single or stereo inputs.
Load-bearing premise
The new multi-view dataset and joint parameter-depth training will generalize to real-world MR device variations and broader user eye diversity beyond the recorded sessions.
What would settle it
Performance degradation on a fresh test set collected with different MR hardware, wider user demographics, or uncontrolled lighting that was not represented in the original dataset.

read the original abstract
We present PicoEyes, a unified gaze estimation framework that directly predicts all key attributes of gaze, including 3D eye parameters, eye-region segmentation, optical axis, visual axis, and depth maps, from either monocular or binocular inputs. The framework simultaneously addresses calibration, gaze forecasting, and varying device postures, while also supporting 3D eye reconstruction via joint estimation of eye parameters and depth maps in an end-to-end manner. In addition, we introduce a large-scale multi-view near-eye dataset containing comprehensive 2D and 3D annotations under diverse conditions, including train, test, rewear-test, and calibration sessions. Extensive experiments demonstrate that PicoEyes achieves state-ofthe-art performance, consistently outperforming both academic and industrial gaze tracking methods across nocalibration, calibration, rewear-after-calibration, and forecasting settings. This work establishes a practical, end-toend paradigm for robust and generalizable gaze estimation in mixed reality (MR) applications.

Referee Report
Summary. The paper presents PicoEyes, a unified gaze estimation framework for mixed reality that predicts 3D eye parameters, eye-region segmentation, optical axis, visual axis, and depth maps from monocular or binocular inputs. It simultaneously addresses calibration, gaze forecasting, and varying device postures via end-to-end joint estimation of eye parameters and depth maps. The authors introduce a large-scale multi-view near-eye dataset with 2D/3D annotations across train, test, rewear-test, and calibration sessions, and report state-of-the-art performance outperforming academic and industrial methods in no-calibration, calibration, rewear-after-calibration, and forecasting settings.
Significance. If the results hold, the work could advance practical MR gaze tracking by unifying multiple tasks into a single end-to-end model and releasing a new dataset that supports evaluation under diverse conditions including rewear and forecasting. The joint 3D-parameter and depth-map estimation is a technical strength that may enable better 3D eye reconstruction.
major comments (3)
- [Experiments] Experiments section: The SOTA claims across no-calibration, calibration, rewear-after-calibration, and forecasting settings rest entirely on internal dataset partitions; the absence of any cross-dataset evaluation on independent near-eye hardware (different cameras, lighting, or demographics) or public gaze benchmarks leaves the generalization step—the key condition for real-world MR applicability—unverified and load-bearing for the central claim.
- [§4] §4 (method) and training details: Loss weighting, hyperparameter choices, and exact data-split procedures are unspecified, preventing assessment of whether the reported outperformance is robust or sensitive to implementation details; this directly affects reproducibility of the unified framework results.
- [Results tables] Results tables: No error bars, standard deviations, or statistical significance tests accompany the performance comparisons, weakening the assertion of 'consistent outperformance' across the four settings.
minor comments (2)
- [Abstract] Abstract: Typo 'state-ofthe-art' should read 'state-of-the-art'.
- [§3] Notation: Clarify how monocular versus binocular inputs are routed through the shared backbone and whether depth-map prediction is active in both modes.

Referee: [Experiments] Experiments section: The SOTA claims across no-calibration, calibration, rewear-after-calibration, and forecasting settings rest entirely on internal dataset partitions; the absence of any cross-dataset evaluation on independent near-eye hardware (different cameras, lighting, or demographics) or public gaze benchmarks leaves the generalization step—the key condition for real-world MR applicability—unverified and load-bearing for the central claim.
Authors: We acknowledge that external cross-dataset validation on independent hardware would provide additional evidence of generalization. However, no existing public near-eye datasets offer the required multi-view 3D annotations, eye parameters, depth maps, and session diversity (rewear, forecasting) to enable direct apples-to-apples comparison with our unified framework. Our dataset was explicitly designed with rewear-test and forecasting partitions to capture real-world variability in device posture and temporal drift. We have added a new Limitations and Future Work subsection discussing this point and outlining plans for cross-hardware evaluation once suitable datasets become available. revision: partial

Referee: [§4] §4 (method) and training details: Loss weighting, hyperparameter choices, and exact data-split procedures are unspecified, preventing assessment of whether the reported outperformance is robust or sensitive to implementation details; this directly affects reproducibility of the unified framework results.
Authors: We agree that these details are essential for reproducibility. We have revised §4 to include: (i) explicit loss weighting coefficients for each task (segmentation, depth estimation, optical/visual axis regression, and eye parameter prediction), (ii) all training hyperparameters (learning rate schedule, batch size, optimizer settings, and number of epochs), and (iii) precise data-split methodology, including participant-level partitioning to prevent identity leakage across train/test/rewear-test/calibration sessions. revision: yes
-
Referee: [Results tables] Results tables: No error bars, standard deviations, or statistical significance tests accompany the performance comparisons, weakening the assertion of 'consistent outperformance' across the four settings.
Authors: We have updated all quantitative tables to report mean values accompanied by standard deviations computed over five independent training runs with different random seeds. We have also added paired t-test results with p-values comparing PicoEyes against each baseline in every setting, confirming statistical significance of the observed improvements. revision: yes
Circularity Check
No significant circularity in derivation or evaluation chain
full rationale
The paper presents a new framework and dataset for gaze estimation, with performance reported on explicitly held-out splits (test, rewear-test, calibration, forecasting) that are described as independent of the training objective. No equations, parameter fits, or derivations are shown that reduce reported metrics to quantities defined by construction from the same inputs. No self-citation load-bearing steps, uniqueness theorems, or ansatz smuggling appear in the provided text. The central claims rest on empirical results from the introduced multi-view dataset rather than tautological redefinitions, making the derivation self-contained against external benchmarks.
