Vogels and Orban (1985) asked subjects to complete several thousand angle judgments at near-principal angles (horizontal or vertical). They found that the just-noticeable difference (JND), the threshold at which people could reliably detect deviation from a horizontal line, was 0.5 degrees after a 600ms exposure to the stimulus. The real purpose of their ...

Citing Muller et al’s, (1955) work on electronic displays, Eastman Kodak’s (1983) Ergonomics Design for People at Work states that people can discriminate 24 different absolute angles of inclination under optimum viewing conditions. This implies that an angle of 360/24 = 15 degrees can be readily classified as inclined rather than flat. However, I’d say 15 ...

From there, I found this page, which cites the image as coming from Gregory's 1970 book The Intelligent Eye. There's also, incidentally, a good list of Gregory's publications on this personal web page, which is probably worth looking at. From a ...

There is a large body of work researching eye movements and what drives viewing patterns. I'll put in some citations later, but it depends on what you're looking at. Things like viewing perspective can modulate how many vertical/horizontal saccades (eye movements) you make. It can depend on the context of the picture, say a face. Here you'll scan the eyes ...

Abed, 1991 found cultural differences in visual scanning patterns that seem to reflect differences in the languages of the cultural groups. Individuals from cultures with languages than may be read vertically as opposed to horizontally tended to have more vertical eye movements than individuals from cultures with horizontally-read languages. Individuals ...
