It all goes back to the visual angle
and how the brain interprets the information sent to it.
Compared to more conventional approaches that use either a concave mirror or a convex lens to increase the visual angle
of a holographic 3D image, this new approach can achieve a higher degree of freedom of display size and visual angle
Consequently, the last fixation prior to the registration of the light barriers with a length of a minimum of 100ms within a visual angle
of 3[degrees] (88 pixels) defined the quiet eye period in milliseconds.
Selective attention of global and local information: Effects of visual angle
, exposure duration and eccentricity on processing dominance.
Note that visual angle
in this paper is not the angle a viewed object subtends at the eye which is called the object's angular size.
When the spider arrived at the end of the path, it was placed into a transparent open glass container and transferred to the center of an arena 90 cm in diameter (wall height, 48 cm; visual angle
, 47[degrees]) (Fig.
The size of the omitted area varied in steps from 10[degrees] x 10[degrees] to 40[degrees] x 54[degrees] of visual angle
The images representing the use of the technology are frequently at a low visual angle
to the viewer.
The second approach we used to examine interfacetal constancy involved what we termed the visual angle
OUR EYES PERCEIVE SIZE BY JUDGING THE VISUAL ANGLE
OF AN OBJECT.
