Sizing it up – Measuring pupil size with head-mounted eye trackers

In order to allow for the right amount of light to enter our eyes, our pupils need to constantly change their size. External light conditions, however, are not the only influence. Our current physiological and psychological condition also has an effect. When we are tired, our pupils tend to shrink. When we are intensely focused […]

Seeing through – An evaluation of Pupil Invisible glasses

Since a couple of months, Pupil Labs is selling its new Pupil Invisible glasses. Being a lead R&D engineer at Pupil Labs, I am super excited about seeing our novel head-mounted eye tracker in the hands of a growing number of users, both in academia and industry. Employing an AI-powered approach to gaze estimation, Pupil […]

Refraction reloaded – Simplifying eye model fitting and refraction modeling

I am happy to announce, that recently my latest computer vision paper was published at ETRA 2019, a major conference in the field of eye tracking. In this collaborative work which was performed at Pupil Labs with Moritz Kassner and Andreas Bulling, we extend on our recent results with respect to eye model fitting and […]

Refraction – Bending over backwards to fit an eye

Recently, together with Moritz Kassner and Andreas Bulling, I have published a paper at Pupil Labs, the company I currently work for. In this work, we present a novel method for fitting a 3D eye model to a set of eye images obtained by a near eye camera. Such cameras, which produce close-up images of […]
