| System
Configuration |
|
The EyeLink 1000 is available in two base configurations,
a head supported system
for use with human participants and a non-human
primate system for use in head fixed primate research applications.

| EyeLink Host PC | ||||
| • | Houses high speed frame grabber for 1000 Hz image acquisition | • | Optional Analog card with break out board | |
| • | Houses high speed Ethernet card for real-time eye data access | • | Response box or game pad connected by USB port. | |
| • | 5 meter Camera Link cable to EyeLink-1000 camera. Cable Extension options available upon request. | • | Runs the EyeLink 1000 host application software in a real-time operating environment | |
| • | 7 meter Ethernet cable to Display PC | • | See Host PC hardware specifications | |

| EyeLink Host Application | ||||
| • |
Performs eye position extraction from frame grabber image frames |
• | Display has real-time feedback of eye data during set-up and recording, freeing display computer's monitor for calibration target and stimulus presentation . Real-time data output through Ethernet or analog card. 2 millisecond sample latency | |
| • | Integrates all needed eye tracking functionality, including participant set-up, calibration, data parsing into eye events and saving of data to disk. | |||

|
||||
| EyeLink Display Computer | ||||
| • |
Software developer's kits for Windows, MS-DOS and Macintosh include the EyeLink API (application programming interface), documentation and sample source code in C for a number of experimental paradigms. |
• | Applications can configure and control the EyeLink tracker, and have access to real-time data including gaze position, response box button presses, and keyboard. | |
| • | C or Python libraries available | |||
| • | Runs optional SR Research Experiment Builder and EyeLink Data Viewer applications -Applications need only support display generation and control of the experiment sequence, and should rely on the tracker for creating the data file and reading the response box. This makes millisecond-accurate display timing possible, even under Windows. | |||

1000 Non-Human Primate System The EyeLink 1000 Non-Human Primate configuration consists of a subset of the EyeLink Head Supported System. The systems 1000 Hz sampling rate, pupil only or pupil-CR tracking modes, low noise, and low, constant, data latency make the EyeLink 1000 an ideal choice for non-human primate researchers. |
Digital data access and eye tracker control is available via the C or Python libraries which utilize an Ethernet interface. Analog data output is also available with the optional analog output card. Simultaneous pupil only and pupil-CR eye position is possible. |

| EyeLink Host Application | ||||
| • |
Performs eye position extraction from frame grabber images. |
• | Real-time data output through Ethernet or analog. 2 millisecond sample latency . When using the analog output option, analog offset and gain can be controlled on-line during recording. | |
| • | Integrates all needed eye tracking
functionality, including participant set-up, calibration (optional),
data parsing into eye events and writing of data to hard disk. |
• | Configurable analog channel output also allows selecting up to 8 channels of data output, for example allowing simultaneous access to pupil and pupil-CR data streams. Alternatively, if the system's built in calibration is used, simultaneous calibrated and uncalibrated data can be accessed. | |
