Abstract: Highlights•Proposed INSLR method improves gaze estimation in noisy real-world settings.•INSLR outperforms NSLR in denoising gaze signals from various datasets.•INSLR enhances oculomotor event classification accuracy.•Effectiveness in minimizing gaze prediction errors from low-precision devices.•Validates INSLR’s denoising quality and sensitivity to attention variations.
