The lab has an SMI RED 250 mobile eyetracker that is portable and can be used for out-of-lab testing. It has a sampling rate of up to 250Hz.
With eyetracking, we can measure participants' gaze to objects or events by tracking the position of the pupil and corneal reflections. Because there is a strong link between visual attention and cognitive processes, eyetracking can provide insights into how different types of speakers understand, process and plan speech. An eye tracker is used to record eye movements relative to the head or the direction of gaze. It is an established method in e.g., psychology, neurology, engineering, and human factors.
