Eyetrackers

SR Research EyeLink

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.
