Probability distributions of best positions versus non-best positions were compared, with position parameterized as the polar angle of eye angle.
In the interests of simplifying the OKR analysis, we show here only the horizontal distance between the pupil and the corneal reflection, referred to hereafter as "eye position", without calculating the angle of eye rotation per se.
Just to watch her sitting down slowly, taking time to lower an arm, change the angle of her eyes, extend a leg, address a colleague: all of these occasionally rekindled my interest in "near the far".
Tangible ideas of distance are elicited not only by (1) visual or "pictorial" depth cues such as object's degree of blurriness (objects appear increasingly "confused" as they approach the observer), but also by kinaesthetic, muscular sensations resulting from (2) changes in the vergence angle of the eyes (1709: §16) and (3) accommodation of the lens (1709: §27).
Thus, the corrugator supercilii muscles pull the eyebrows toward the bridge of the nose, making a projecting "roof" over the medial angle of the eye and producing characteristic furrows in the forehead; the roof is used primarily to protect the eye from the glare of the sun.
In a simple way, it registers the view angle of an eye slipping along the reflector surface.
These markers were placed from top to the bottom as follows: at the top of the head, at the level of the external angle of the eye orbit, on C7, on the left shoulder acromion, on the left elbow, on the left wrist, on the left antero-superior iliac spine, the left great trochanter, the left knee and the left internal malleolus and on the 5th metatarsien (figure 1).
The blood was collected from the internal angle of the eye using heparinised capillary tubes of 2 3 mm.
Blood was obtained from the ophthalmic sinus at the medial angle of the eye behind the nictitating membrane [ 37].
Silicone skin replicas were taken from the left crow's feet region 5 mm from the lateral angle of the eye.
