Talk:Parallax barrier

Untitled
"[...] without the need for the viewer to wear glasses." -- something needs to be added to clarify this. The viewer doesn't need to wear *3d* glasses, it's not like the system allows people who normally wear vision correcting glasses to no longer wear them. —Preceding unsigned comment added by 24.9.226.55 (talk) 00:58, 11 January 2010 (UTC)

Anyone want to improve the too-restrictive definition?
As of Sep 30, 2010, the article defines "parallax barrier" in a way that is not general enough. At the moment, it says "A parallax barrier is a device to allow a liquid crystal display to show a stereoscopic image without the need for the viewer to wear 3D glasses. Placed in front of the normal LCD, ...". Actually, a parallax barrier (or raster barrier) - assuming its function is display - can be placed on any image source, such as film, LCD, a rear-projected image, etc. Also, the resulting imagery can be two-view (autostereoscopic, being a parallax stereogram), multi-view (automultiscopic, being a parallax panoramagram), or non-three-dimensional multi-view (as in Rufus Butler Seder's "Scanimation"). The historical overview I like best about this is Michael Halle's _Autostereoscopic displays and computer graphics_ (ACM SIGGRAPH 31(2) May 1997 pp 58-62). Does someone here have the energy to edit this Wikipedia article? It would also be useful to incorporate the distinction between parallax stereograms and parallax panoramagrams, as well as include references to F. E. Ives (1903) and H. E. Ives (1928). (Why don't I just do it? My edits seem to be frequently reverted.) Gregg Favalora (talk) 15:50, 30 September 2010 (UTC)
 * I reworded the first paragraph slightly to broaden the term to include any image source. — Fire Fly  ~  22:27, 11 November 2010 (UTC)

An MIT group created a design called "content-adaptive parallax barrier":
