The “MRC Eye-Tracking” software is an easy-to-use and very accurate software for the tracking of gaze directions and monitoring of pupil sizes. It is ideal for monitoring the fixation of subjects during fMRI sessions. “MRC Eye-Tracking” is available in different versions including hi-speed, monocular and bin­o­cu­lar configurations, and with flexible options for interfacing with third party software, your own software, and hardware triggers.

Features

  • Highest accuracy*
  • Live view and real-time data output
  • Different calibration screens
  • Visualisation of gaze points in control screen
  • TCP/IP socket for interfacing with Matlab, Presentations, E-Prime, etc.

  • * Typical accuracy for gaze detection is 0.4° (depends on focal length and distance from eye to calibration screen).

Camera/mirror mounts

Our camera/mirror mounts are available for many different head coils. On each mount, one or two cameras can be placed behind the semi-transparent mirror. The cameras can look through the mirror onto the eyes, whereas the subject cannot see the camera behind the mirror. Thus it is possible to present a stimulus via the mirror and perform eye-tracking.

We offer our camera/mirror mounts for different head coils. If your head coil is not listed in the selection of supported coils, please ask us. In many cases a solution is possible.
