Tieferer Einblick in das menschliche Verhalten

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.

Tobii Pro Spectrum has four different eye tracking modes for different groups of primate species: Human Great ape Monkey Small monkey

60 Hz, 120 Hz, 150 Hz, 300 Hz, 600 Hz, or 1200 Hz (max. frequency depends on hardware version)

Head supported² 0.01° RMS at optimal conditions (applying Savitzky-Golay filtering, settings listed in the test report) 0.06° RMS at optimal conditions (raw signal)

Head free-to-move³ 0.02° RMS at optimal conditions (applying Savitzky-Golay filtering, settings listed in the test report) 0.08° RMS at optimal conditions (raw signal)

Head supported² Down to 0.16° Median: 0.30° (P25: 0.24° - P75: 0.41°)

Head free-to-move³ Down to 0.17° Median: 0.43° (P25: 0.32° - P75: 0.59°)

Timestamp Gaze origin Gaze point Pupil diameter

Eye openness stream has the same frequency as frequency selected for the gaze stream and will have the same timestamps. Eye openness data is provided in millimeters, for each eye individually.

Eye image stream frequency is 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.

8–bit timestamped data (256 event codes) 
Event driven detection with a timestamp accuracy of 50 µs

Integrated between the eye tracker time domain and the client computer time domain with an accuracy of 100 µs

Binocular, Monocular

Excellent
Dual-camera system, with more images than a one camera system, gives a more accurate data calculation and the best level of precision and robustness for head movement.

55 to 75 cm (22" and 30") from the eye tracker

Freedom of head movement at 65cm distance 34 cm x 26 cm (13.5" x 10")

Freedom of head movement at 75cm distance 42 cm x 26 cm (16.5" x 10")

Up to 24" (16:9 aspect ratio)

Supplied 23.8" monitor

Eye tracker unit can be used alone or together with the monitor or other screens.

Can also be used with real-world stimuli.

Tracker mounted on stand, allows for even larger screens and physical objects to be tracked.

Very simple and easy. Typically, less than 1 minute.
