some links about visual depth perception effects


an interesting visual phenomenon is the Pulfrich effect, used in some of the films and performances by experimental filmmaker Ken Jacobs:

His patents are here:

and a reflection on this work:

Bela Julesz did a lot of very interesting research into depth perception without object cues, in random dot stereograms:

He wrote a classic book on the subject:
"Foundations of Cyclopean perception",
The University of Chicago Press, Chicago, 1971.

This book has recently been republished by MIT press:

and this brings us to the intriguing subject of 'Random Dot Cinematography':
