The EyeLink 1000 is a head supported eye tracking system offering 1000 Hz pupil - CR eye tracking. The system has been designed for computer based eye tracking research, offering excellent accuracy and the ideal specification set for gaze and saccade contingent research.
SR Research EyeLink 1000 and (right) Desktop Optics Option
EyeLink® 1000 is a video based eye tracking device that offers a 1 kHz sampling rate with excellent gaze accuracy and spatial resolution, surpassing any other video based eye tracker available today. EyeLink® 1000 is ideally suited for a wide range of computer based eye tracking research, including reading, visual search, and oculomotor studies.
EyeLink® 1000 is provided with a standard Mirrored Optics configuration that uses an infrared mirror to optimize eye tracking range. An optional mirror-less Desktop Optics configuration is also available which can be used with any chin rest and provides a totally unobstructed field of view. The EyeLink CL camera can be easily mounted in either optics configuration depending on which best suits the experimenter’s needs.
EyeLink® 1000’s unique Focal Imaging technology provides extremely high resolution eye data without the result of a limited camera field of view, allowing eye position to be tracked even when the head moves +/- 25 mm horizontally or vertically. Robust eye tracking in conditions of moderate head movement allows for a less restrictive head restraint or the use of only a forehead rest, ideal for studies where verbal responses are required.
An EyeLink® Eye Tracker, coupled with the SR Research Experiment Builder and EyeLink Data Viewer software, offer researchers the most complete, powerful, and easiest to use, eye tracking package on the market.
System Configuration
This diagram illustrates a typical EyeLink-1000 system configuration. A Host computer houses a high speed frame grabber and Ethernet card. The frame grabber is connected to the EyeLink CL 1000 Hz camera via a Camera Link cable. The Ethernet card is used to connect the Host computer to a Display computer which runs the experimental paradigm for the participant.
Software
The following software components are included wth the base EyeLink 1000 system.
