The EyeLink II system consists of three miniature cameras mounted on a padded headband. Two eye cameras allow binocular eye tracking or selection of the subject’s dominant eye.
An optical head-tracking camera integrated into the headband allows accurate tracking of the subject’s point of gaze without the need for a bite bar.
|500 Hz binocular eye monitoring|
|0.5º average accuracy|
|Access eye position data with 3.0 msec delay|
|0.01º RMS resolution|
|High quality computer based or scene camera eye tracking|
|Fast and simple participant setup, calibration, and validation|
The Tobii T60 and T120 Eye Trackers are integrated into a 17" TFT monitor. They are ideal for all forms of eye tracking studies using screen based stimuli.
There is a Tobii setup in the babylab, which is in a fixed lab setup.
There are also two mobile Tobii setups. Please contact Gero Lange (mailto:firstname.lastname@example.org) for booking requests. Please keep in mind that these mobile setups are booked _without_ a room. If you plan to use these eyetrackers, make sure to also book a room that can be locked. You can use it in a cubicle, as long as you make sure that the eyetracker is stored in a locked room at the end of the day.
