=== Eye-tracking while driving a car in a difficult situation ===

The eye movement of two groups of drivers have been filmed with a special head camera by a team of the Swiss Federal Institute of Technology: Novice and experienced drivers had their eye-movement recorded while approaching a bend of a narrow road. The series of images has been condensed from the original film frames<ref>Cohen, A. S. (1983). Informationsaufnahme beim Befahren von Kurven, Psychologie für die Praxis 2/83, Bulletin der Schweizerischen Stiftung für Angewandte Psychologie</ref> to show 2 eye fixations per image for better comprehension.

Each of these stills corresponds to approximately 0.5 seconds in real time.

The series of images shows an example of eye fixations #9 to #14 of a typical novice and of an experienced driver.

Comparison of the top images shows that the experienced driver checks the curve and even has Fixation No. 9 left to look aside while the novice driver needs to check the road and estimate his distance to the parked car.

In the middle images, the experienced driver is now fully concentrating on the location where an oncoming car could be seen. The novice driver concentrates his view on the parked car.

In the bottom image the novice is busy estimating the distance between the left wall and the parked car, while the experienced driver can use their [[peripheral vision]] for that and still concentrate vision on the dangerous point of the curve: If a car appears there, the driver has to give way, i.e. stop to the right instead of passing the parked car.<ref>Pictures from {{harvnb|Hunziker|2006}}</ref>

More recent studies have also used head-mounted eye tracking to measure eye movements during real-world driving conditions.<ref>{{cite journal |last1=Grüner |first1=M |last2=Ansorge |first2=U |title=Mobile eye tracking during real-world night driving: A selective review of findings and recommendations for future research |journal=Journal of Eye Movement Research |date=2017 |volume=10 |issue=2 |pmid=33828651| doi=10.16910/JEMR.10.2.1|pmc=7141062 |doi-access=free }}</ref><ref name="bop.unibe.ch"/>
