Eye-tracking refers to a collection of technologies for sensing where a person is looking (termed “point of regard”). Eye-tracking is a popular measure in its own regard in research on reading, visual attention, marketing / advertising and psychiatric disorders such as schizophrenia. We offer several types of eye-tracking solutions brought to you by SR Research Ltd and Cambridge Research Systems Ltd., including high frame rate systems up to 2000 frames/second, remote systems that do not require head fixation, high-precision systems for use inside the fMRI scanner and affordable systems for simple fixation monitoring in behavioral and ERP applications.
We provide integration assistance with the EEG systems we sell. If you are buying an eye-tracker for stand-alone use, let us know your application so we can help you settle on the best fit. If you intend to use the eye-tracker with a system you already own that we sell or support, let us know the serial number of the unit. If you want the eye-tracker to be provided as part of a complete laboratory configuration, knowing some details about your application will let us guide you to the most convenient and cost-effective solution.
Other Ocular Monitoring Methods Not Considered Eye-Tracking
Note that there are other ways of measuring eye movements that do not provide enough information to determine point of regard, but those are listed elsewhere in the site. For example, electrooculogram (EOG) can be measured with any DC bioamplifier, and it is often used to detect large movements away from a fixation point, but it is not generally considered suitable for determining point-of-regard. Similarly, the Jazz Vigilance Monitor for use with ActiveTwo monitors ocular motility within the head/socket but due to viscoelasticity, the signal is not suitable for determining point-of-regard. Jazz provides a very high frame rate and high sensitivity, which make it useful for microsaccade detection.
