Sam Hutton

About Sam Hutton

Sam Hutton studied Experimental Psychology at the University of Sussex, and liked it so much he stayed there to do a PhD. His first encounter with an eye tracker was during his post-doctoral fellowship at Imperial College, London. He was based in the Neuro-opthalmology unit at Charing Cross Hospital for 6 years, and whilst there learned to use an ancient infrared eye tracking system to measure basic oculomotor function (prosaccades / antisaccades / smooth pursuit etc) in patients with neuropsychiatric and neurological disorders. He was hooked, and has been actively involved in eye tracking research in one way or another ever since. When not writing blogs (e.g. most of the time...) he works with the rest of the SR Research Support Team on a range of projects, taking a particular interest in issues involving eye tracking in clinical settings (for example eye tracking nystagmus / neurological disorders) and pupillometry. He can also be found teaching eye tracking workshops on a range of topics, and generally trying to make sure that people don't make the same mistakes he did. He loves to eye track animals, and has so far managed to record gaze from mice, cats, dogs and a duck...

Eye Tracking Terminology

Eye Tracking Terminology – Eye Movements

July 2, 2020

Eye tracking research can sometimes feel like a bit of a terminological minefield, particularly if you are new to the topic. In this blog (the first of a series) I outline some of the key terms that refer to eye movements themselves. Future blogs will address the terminology around eye tracking data

Eye Tracking Publications We have recently finished updating our database of EyeLink publications - there were more than 900 papers published in 2019 alone, and the database now contains well over 8000 publications in total. Each publication is checked individually to ensure that it contains data

Visual Angle Calculation

Visual Angle

December 2, 2019

The concept of visual angle is critical to many aspects of eye tracking research, but it is one of those things that people are somehow just expected to understand. This blog is my attempt to explain visual angle in the way I wish someone had explained it to me, e.g. with the bare minimum of math...

Eye Tracking for Pupillometry

Eye Tracking for Pupillometry

June 3, 2019

Researchers are increasingly using eye trackers to explore changes in pupil size (pupillometry) in order to reveal insights into cognitive processes. EyeLink eye trackers are capable of detecting changes in pupil size of just 0.1% of the pupil diameter, and their high sampling rates allow pupilliary

What is eye tracking?

What is eye tracking?

July 13, 2018

What is eye tracking? Put simply, eye tracking is the process of measuring eye movements. A typical goal for eye tracking research is to establish where people look (i.e., their “point of regard” or “gaze"). To this end, scientists usually use a video-based eye tracker, such as the EyeLink 1000
