A system for detecting an accessible bug

We have described each of the operations on the retinal image in terms of what common factors in a large variety of stimuli cause response and what common factors have no effect. What, then, does a particular fiber in the optic nerve measure? We have considered it to be how much there is in a […]

The screen is looking at you in the eyes

Some symptoms of CVS include headaches, blurred vision, neck pain, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness, polyopia, and difficulty refocusing the eyes. In CVS, the screen […]

A vision substitution system

Two illustrations of Bach y Rita’s vision substitution system, in 1969. “Four hundred solenoid stimulators are arranged in a twenty x twenty array built into a dental chair. The stimulators, spaced 12 mm apart, have 1 mm diameter “Teflon” tips which vibrate against the skin of the back (Fig. 1). Their on-off activity can be […]

Upside-down inversion goggles experiments

Living In A Reversed World documents an experiment by Erismann & Kohler during which the subjects were required to wear goggles transforming their perception, between six to 124 days. The film is narrated by James J. Gibson. More on the experiment: http://www.awz.uni-wuerzburg.de/en/archive/film_photo_and_tone_archives/video_documents/th_erismann_ikohler
