The Display Makes a Difference: A Mobile Eye Tracking Study on the Perception of Art Before and After a Museum's Rearrangement.

There is increasing awareness that the perception of art is affected by the way it is presented. In 2018, the Austrian Gallery Belvedere redisplayed its permanent collection. Our multidisciplinary team seized this opportunity to investigate the viewing behavior of specific artworks both before and after the museum's rearrangement.

The impact of slippage on the data quality of head-worn eye trackers.

Mobile head-worn eye trackers allow researchers to record eye-movement data as participants freely move around and interact with their surroundings. However, participant behavior may cause the eye tracker to slip on the participant's head, potentially strongly affecting data quality. To investigate how this eye-tracker slippage affects data quality, we designed experiments in which participants mimic behaviors that can cause a mobile eye tracker to move.

Non-intrusive practitioner pupil detection for unmodified microscope oculars.

Modern microsurgery is a long and complex task requiring the surgeon to handle multiple microscope controls while performing the surgery. Eye tracking provides an additional means of interaction for the surgeon that could be used to alleviate this situation, diminishing surgeon fatigue and surgery time, thus decreasing risks of infection and human error. In this paper, we introduce a novel algorithm for pupil detection tailored for eye images acquired through an unmodified microscope ocular.
