【Eye tracking specifications】
1. Technique: Video-based pupil- and corneal reflection eye tracking with dark and bright pupil illumination modes. Two cameras capture stereo images of both eyes for robust accurate measurement of eye gaze and eye position in 3D space, as well as pupil diameter.
2. Mode：Human, great ape, monkey, small monkey
3. Sampling frequency：1200, 600, 300, 150, 120 or 60 Hz
4. Precision: 0.01° RMS (Root mean square sample- to-sample deviation) at optimal conditions (Savitzky-Golay filtering applied), 0.06° RMS at optimal conditions (raw signal)
5. Accuracy: 0.3° at optimal conditions
6. Binocular eye tracking: Yes
7. Eye tracker latency: Mean latency < 2 ms at 1200 Hz (SD < 0.2 ms)
8. Blink recovery time: 1 frame (immediate)
9. Gaze recovery time: ＜150 ms
10. Data sample output: Timestamp, gaze origin, gaze point, pupil diameter, etc.
11. Eye openness stream: has the same frequency as the gaze stream and will have the same timestamps. Eye openness data is provided in millimeters for each eye individually.
12. Eye image data stream: approximately 10 Hz (one image with both eyes). Zoomed-in eye images available in tracking mode. Full-frame camera images are available in gaze recovery mode
13. TTL input stream: 8–bit timestamped data (256 event codes). Event-driven detection with a timestamp accuracy of 50 µs.
14. Tracker and client time synchronization: Integrated between the eye tracker time domain and the client computer time domain with an accuracy of 100 µs.
【Setup & Eye tracker unit】
1. Head movement tolerance: dual-camera system delivers more images than a single camera system, enabling a more accurate data calculation and the best level of precision and robustness for head movement.
2.1 Freedom of head movement (@65 cm distance): Width x height: 34 cm x 26 cm (13.5” x 10”) ,at least one eye tracked.
2.2 Freedom of head movement (@75 cm distance): Width x height: 42 cm x 26 cm (16,5” x 10”), at least one eye tracked.
3. Operating distance (mounted on screen): 55 to 75 cm (22” and 30”) from the eye tracker.
4. Set up options: (a) Screen and eye tracker mounted together (b) Standalone eye tracker (c) Tracker and screen mounted on any standard VESA mount (d) Eye tracker used with external monitor.
5. Connectors: TTL input - 8-bit (DB-9 connector), Communication - Ethernet (RJ-45 connector), Power supply - 24 VDC (5.5 mm connector).
6. Eye tracking cameras: 2.
7. Illuminators: Dark pupil Illumination Modules, Bright pupil Illumination Modules
8. Software: Tobii Pro Lab, Tobii Pro Eye Tracker Manager, Tobii Pro SDK
【Equipped Monitor】
1. Monitor model name: EIZO FlexScan EV2451
2. Panel type: IPS, LED backlight
3. Screen size (diagonal): 23.8”
4. Aspect ratio: 16:9
5. Resolution: 1920 x 1080 pixels
6 .Screen response time: 5 ms (gray-to-gray)
7. Built in speakers: 1.0 W + 1.0 W
8. Power supply: 100-240 VAC 50/60 Hz
9. Connectors: DVI, VGA, HDMI, Display port, 1 port for monitor control (USB 3.0), 2–port USB hub (USB 3.0), C13 power connector, Audio input connector: 3.5 mm, headphone jack: 3.5 mm
