The brain, in fact, can perform tricks to make up for the eyes' shortcomings. Singman recalls the case of a patient who after eye surgery, suddenly discovered that when he covered that eye, he couldn't see out of the other, supposedly good eye. When a doctor examined the patient, it...
Mapping the polar-angle representation of eye movements in human superior colliculusDavid Ress
The reason is that the the measured focal length of the eye isn’t what determines the angle of view of human vision. I’ll get into this in more detail below, but the main point is that only part of the retina processes the main image we see. (The area of main vision is called ...
Left Eye Dual Eye Overlap Right EyeOur central angle of view — around 40-60° — is what most impacts our perception. Subjectively, this would correspond with the angle over which you could recall objects without moving your eyes. Incidentally, this is close to a 50 mm "normal" focal ...
As an observer views the eye from an increasingly oblique angle, the pupil takes on an ever-more ellipitical appearance. Mathur and colleagues6 measured the shape of the entrance pupil as a function of the nasal and temporal visual field positions of a camera moved about a stationary eye. ...
Perception is often modelled as a process of active inference, whereby prior expectations are combined with noisy sensory measurements to estimate the structure of the world. This mathematical framework has proven critical to understanding perception, co
method is used in the context of exploring the potential opportunities of wearable shape-changing robotic devices; these devices have significantly different characteristics from our digital platforms, which allows for showing insights more objectively by extracting diverse insights from an alternative angle...
Dias et al. [14] circumvented this limitation by employing a spherical retina shape and replacing the Gullstrand model with the wide-angle aspherical Navarro eye model. Figure2displays a comparison of the ray-tracing process on two retina shapes. ...
So even fully automated processes can require manual intervention to judge which outputs are perceptually pleasing to the human eye. Hall and Song [9] point out that in what they call Simple Art, that is the art of children, of Miró and of cave paintings, the defining characteristic is ...
Briefly, participants dichoptically viewed two horizontally moving gratings through a mirror stereoscope, while we recorded optokinetic nystagmus (OKN) in one eye. The slow phases (smooth pursuit) of the OKN pattern revealed which direction of movement was consciously perceived at the time47,48,49....
