Remote Eye Tracker

A remote eye tracker is a camera-based system that measures where a person looks without requiring physical contact, making it useful for studying visual behavior in natural or laboratory settings. The device typically uses infrared illumination and image analysis to locate the pupil and corneal reflection, then estimates gaze direction, fixation, and eye movements relative to a display or scene. Researchers use remote eye tracking to investigate attention, visual scanning, reading, decision-making, and responses to environmental or digital stimuli. These measurements provide behavioral indicators of information processing and support applications in psychology, neuroscience, education, usability research, and human-computer interaction.

2017

We recently proposed a method that allows dichoptic visual stimulus presentation and binocular eye tracking simultaneously1. The key is the combination of an infrared eye tracker and the corresponding infrared-transparent mirrors. This manuscript provides an in depth protocol for initial setup and everyday operation.

Eye Tracking in Cognitive Experiments

0 Views •

2023

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better understand neural deficits in patients with cognitive impairments. In this video, we will first look at an...

Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.
