Eye-tracking

EyeLink 1000 desktop mount

The EyeLink 1000 supports both monocular (sampling rate of up to 2000 Hz) and binocular (sampling rate of up to 1000 Hz) recording. The desktop mount means that no electronics are placed near the participants head. For high sample rate recordings (> 500 Hz) it is recommended to use the chin-rest.

The visual stimulus delivery package Experiment Builder is available to use with the EyeLink 1000, in addition to Data Viewer for data analysis. The eye tracker can also work with other stimulus presentation packages such as Presentation and PsychoPy (both Python based). 

The Lab has two different lenses for the eye tracking camera:

  • 60mm
  • 50mm

Usually situated in Lab 2A.

Tobii T60XL

The Tobii T60XL eye tracker provides an unobtrusive way of recording gaze data. Cameras are integrated in to the 24 inch widescreen monitor, enabling data to be collected in a naturalistic manner.

Tobii Studio, the intuitive stimulus presentation package, is installed on one computer in Lab 2. The Lab has one site recording license for Tobii Studio, and three non-recording licenses. Therefore it is possible to setup your study outside of the Lab environment. Furthermore, data analyses can be conducted outside the Lab. 

The eye tracker has a sampling rate of 60 Hz, and is apt for large stimuli displays.

Usually situated in Lab 2B.  

Eye-tracking in VR

With HTC Vive Bionocular Add-on from Pupil Labs you enable eye tracking in the participants' virtual reality experience. The eye tracking add-on is connected to an open-source software. Eye videos are transferred to your host via USB 2.0. 

  • Tracking frequency 120 Hz
  • Gaze Accuracy ~1.0deg
  • Gaze Precision ~0.08deg
  • Camera Latency 5.7 mm.
  • Processing Latency 3-4 ms on i5 CPU
  • Resolution 640x480
