The 2000 Hz Binocular High Speed Camera Upgrade allows the EyeLink 1000 Plus camera to sample eye movements at up to 2000 Hz binocularly or in a 2000 Hz low noise monocular mode. With the Remote Camera Upgrade, the same camera can sample at up to 1000 Hz binocular with head free-to-move tracking.
The 2000 Hz upgrade provides the fastest possible eye position access, and is therefore ideal when the system is being used for gaze-contingent display manipulations.
The following figure shows a 1000 Hz binocular recording of X, Y eye traces in a sinusoidal smooth pursuit task.
Beginning in the Spring of 2017, the 2000 Hz Bincoular High Speed Camera Uprade comes standard with every EyeLink 1000 Plus and EyeLink Portable Duo.
Existing owners of the EyeLink 1000 Plus can upgrade for a nominal fee - please write email@example.com for details.
