Fast, Accurate, Reliable Eye Tracking

The EyeLink® 1000 Plus Core System

The EyeLink 1000 Plus Core system consists of a High-Speed Camera (up to 2000 Hz binocular tracking included standard with every camera) that is specially constructed for eye tracking and a Host PC that is dedicated to processing the camera data. The unparalleled technical specifications that our systems achieve stem from the Core's capabilities.

The EyeLink 1000 Plus includes:

  • low spatial and temporal noise
  • high sampling rates:
    • up to 2000 Hz binocular tracking with the head stabilized,
    • low noise 2000 Hz monocular head stabilized tracking
    • or up to 1000 Hz binocular tracking with the head free-to-move
  • dual-use functionality as remote eye tracker or head-supported system
  • usable seamlessly in the lab or in MEG/MRI environments
  • low latency and low variability in sample availability for gaze-contingent paradigms
  • multiple mounts for specialized eye-tracking for infants, patients in hospital beds, desktop tracking, reading, reaching, pointing, NHP tracking and more...
  • focal imaging technology for a wide camera field of view and easier setup

Depending on the mount used with the camera, and the camera upgrades purchased, the core system can be used as either a high-speed, high-precision, eye tracking system with the head stabilized OR as a remote eye tracker with the head free-to-move.

No other eye tracker in the world has this level of versatility!
