Tobii Pro Spectrum
Náš nejvýkonnější eye tracker navržený pro nejintenzivnější výzkum lidského chování zachytí i ty nejrychlejší pohyby očí, jako jsou mikrosakády. Tobii Pro Spectrum sbírá data až do 1200 Hz, přičemž stále umožňuje přirozený pohyb hlavy. Lze ho použít s obrazovkou nebo v reálném prostředí a dokonce i ve výzkumu s opicemi.
Technické parametry
Eye Tracking
| Eye tracking 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. |
| Eye tracking mode | Human, Monkey, Great Ape |
| Sampling frequency | 60 Hz, 120 Hz, 150 Hz, 300 Hz, 600 Hz, or 1200 Hz |
| Precision | Head free to move 0.08 RMS at optimal conditions (raw signal) |
| Accuracy | Head free to move Down to 0.17° |
| Binocular eye tracking | Yes |
| Data sample output | Timestamp Gaze origin Gaze point Pupil diameter |
| User calibration | Binocular, Monocular |
Setup
| Head movement tolerance | 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. |
| Operating distance (mounted on screen) | 55 to 75 cm (22″ and 30″) from the eye tracker |
| Freedom of head movement (width x height) | 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″) |
| Optimal screen size | Up to 24″ (16:9 aspect ratio) |
| Recommended monitor | Supplied 23.8″ monitor |
| Tracker setup options | 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. |
| Participant setup | Very simple and easy. Typically, less than 1 minute |
Tobii Pro Fusion
Náš všestranný a výkonný eye tracker střední třídy se dvěma kamerami zachycuje eye trackingová data při 250 Hz. S tímto statickým eye trackerem, který se připevňuje k obrazovce, můžete zkoumat jak fixace, sakády tak smooth pursuit a to uvnitř i mimo laboratoř. Upevněný na tripodu poslouží pro studie v reálném prostředí.
