EYE TRACKING

The HIT centre is equipped with several remote and head-mounted devices that allow to monitor the eye movements, several pupillometric indices and other eye-related measures (e.g. saccades, microsaccades, blinks). These tools can be coupled with other instruments in order to concurrently co-register different physiological signals (e.g. EEG, EDA, fEMG, HR). All these equipments are useful in investigating the research field of social and cognitive ergonomic (e.g. human-computer interaction).

The 500 Hz ET remote eye tracker (SMI RED 500) allows to monitor remotely eye behavior and pupil diameter. This tool is reliable in measuring fixations, saccades, microsaccades, blinks (number and duration), as well as pupil dilation. Moreover, the device is totally not invasive and it is tolerant to head movements.
The 120 Hz ET remote eye tracker (Tobii X120) allows to monitor remotely eye behavior and pupil diameter. This tool is reliable in measuring fixations, saccades, blinks (number and duration), as well as pupil dilation. Moreover, the device is totally not invasive and it is tolerant to head movements.
The 50 Hz ET remote eye tracker (Tobii 1750) allows to monitor remotely eye behavior and pupil diameter. This tool is reliable in measuring fixations, saccades, blinks (number and duration), as well as pupil dilation. Moreover, the device is totally not invasive and it is tolerant to head movements.
The ET for immersive VR (nVisor SX111) allows to monitor monocularly eye behavior and pupil diameter of the right eye. This tool is reliable in measuring fixations, saccades, blinks (number and duration). Moreover, the device is totally not invasive and it is completely unaffected by head movements. This tool is suited to be utilized in the virtual reality research field. It can acquire data at a sampling rate of 60 Hz.
The 120 Hz binocular (Pupil Labs - glasses binocular) eyeglasses allows to monitor behavior and pupil diameter both monocularly (right eye) or binocularly eye. These tools are reliable in measuring fixations, saccades, blinks (number and duration). Moreover, these device are totally not invasive and they are completely unaffected by head movements. They can acquire data at a sampling rate of 30 Hz (monocular pair) or 120 Hz (binocular pair).
