My research focuses on developing calibration-free gaze-tracking technology. Traditional eye-trackers require user calibration and lose accuracy with head movement. This research aims to create uncalibrated, accurate gaze-tracking that allows for freedom of movement. The core innovation is a novel interpolation-based Gaze-to-Object Mapping (GTOM) method, which provides uncalibrated, accurate tracking with user mobility. This method uses mathematical models of the eye and its physical properties to generate synthetic calibrations, enabling accurate tracking without the need for user-specific calibration.

Application areas include gaze tracking in dynamic public spaces where user calibration would be impractical.

I hold a PhD in computational geometry, with a focus on levels of detail for animated polygonal models. My research addressed the challenges of simplifying complex animated models while preserving their visual fidelity.
