Editing Eye tracking (section)

=== Eye-tracking of younger and elderly people while walking ===
While walking, elderly subjects depend more on [[fovea centralis|foveal]] vision than do younger subjects. Their walking speed is decreased by a limited [[visual field]], probably caused by a deteriorated peripheral vision.

Younger subjects make use of both their central and peripheral vision while walking. Their peripheral vision allows faster control over the process of walking.<ref>{{Cite journal | doi=10.2466/pms.2002.94.3c.1283| pmid=12186250|title = Comparative Study of Eye Movements in Extent of Central and Peripheral Vision and Use by Young and Elderly Walkers| journal=Perceptual and Motor Skills| volume=94| issue=3_suppl| pages=1283–1291|year = 2002|last1 = Itoh|first1 = Nana| last2=Fukuda| first2=Tadahiko| s2cid=1058879}}</ref>
