Figure 1: The full black circle is the point of fixation.

Such large ranges, in particular, those that extend leftwards from the point of fixation, may have been due to the 'wandering effect'.

Loss of visual acuity may start with a blur or haze at the point of fixation, followed by a progressive decline.

But a third point of fixation is the contrast Winvian strikes with the Mayflower Inn & Spa.

Jani straightened the straps of her duffel, conscious to the point of fixation of the memory of John's touch.

With ophthalmologist Richard Förster (1825-1902), he performed a series of tests on vision outside the point of fixation, which they referred to as indirect vision.

Ocular flutter is an opsoclonic disorder in which the eyes incontinuously saccadically move around the point of fixation in the field of vision.

Variation disappears when a new allele reaches the point of fixation - when it either disappears from the population or replaces the ancestral allele entirely.

Peripheral vision is usually spared since the pattern of loss typically involves a central or cecocentral scotoma, a visual field defect at or surrounding the point of fixation.

Areas near the cricoid cartilage and carina are fixed to the thyroid cartilage and the pericardium respectively; thus if the airways move, they can tear at these points of fixation.

Impairments in set shifting ability are a notable feature of executive dysfunction; set shifting is the cognitive ability to dynamically change focus between points of fixation based on changing goals and environmental stimuli.

It might be only that Geilie had decided to try my technique-if one could dignify it with such a word-as well as her own, and use the image of Brianna as a point of fixation for her travel.

Stereoscopic depth perception was studied by Durnford and Kimura (1971) by asking subjects to judge whether two rods, one presented at the point of fixation and one presented in the left or right visual field, were horizontally aligned.

A second year student of Seitetsu Gakuin High School, he has a crush on Kaede Sakura, one of the school's beauties, to the point of fixation and sees other girls with indifference, and is later very dense about the feelings of Shizuku, Akane and Mikoto.

This supports a theory put forward earlier at La Brea by William A. Akersten that the sabers were used primarily not to stab but as points of fixation to allow the beast to rip off a huge roll of flesh, perhaps 8 to 10 pounds of meat, in the estimate of Dr. Heald.

He drew a line from the eyes of the statues to the point of regard, made a private mark on the wall, and then retired.

(The same effect can occur if the display is moving with respect to the observer's point of regard.)

Because most multiplexed displays do not present the entire display simultaneously, they are subject to "break up" if the observer's point of regard is in motion.

The vector between the pupil center and the corneal reflections can be used to compute the point of regard on surface or the gaze direction.

This led to the realization that visual or retinal error (the difference between the post-saccadic point of regard and the target position) played a role in the homeostatic regulation of saccade amplitude.

Nystagmus is characterised by the combination of 'slow phases', which usually take the eye off the point of regard, interspersed with saccade-like "quick phases" that serve to bring the eye back on target.
