Applications include web usability, advertising, sponsorship, package design and automotive engineering. In recent years, the increased sophistication and accessibility of eye tracking technologies have generated a great deal of interest in the commercial sector. Eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human computer interaction, and in product design. Micro USB, RJ45 (Ethernet), 3.An eye tracker is a device for measuring eye positions and eye movement. Rechargeable 18650 Li-ion, Capacity: 3400 mAh ST™ LSM9DS1 sensors: Gyroscope and Accelerometer (sampled at 100 Hz) Magnetometer: (sampled at 10 Hz) Scene camera, field of view (horizontal and vertical) Grilamid plastic, with clip on attachments Grilamid plastic, stainless steel, optical grade plastic lenses The built-in accelerometer, gyroscope, and magnetometer sensors provide differentiation between head and eye movements, which eliminates the impact of head movement on eye tracking data. Slippage compensation technology and persistent calibration enable robust and consistent eye tracking data throughout recordings, even if the glasses move on the participant’s head, or are taken off and on.
The integration of Tobii’s core eye tracking technology into the lenses allows optimal positioning of the eye tracking cameras and illuminators, while Tobii’s patented 3D eye model combined with two eye cameras per eye delivers very accurate gaze data with minimal data loss and robust pupil size estimation. This means the wearer can see more and the system can capture more, which is useful for research involving tasks were participants need to look down and up regularly, or if the subject matter covers a large area within the wearer’s field of view.
The integration of the illuminators and eye cameras into the lenses removes obstruction to the wearer’s vision, while the wide-angle scene camera allows gaze data to be recorded over a large field of view. Tobii Pro Glasses 3 has been designed to deliver comprehensive eye tracking data at a variety of gaze angles.
