Gesture recognition does not require '2 video stereo cameras', it can be accomplished with just one camera. Does gesture recognition need to be distinguished from gesture tracking? It would be good to see information about the various techniques that can be used (computer vision-based & accelerometers are the two I know of). Mentions of HandVu and OpenCV wouldn't go astray either.
algorithm-based implementations overviews
I believe this article could do with some additional attention by someone who knows more about the variety of strategies and methods used for the actual implementation of gesture recognition, as depending on what forms of interaction are being used, different strategies can be taken to accomplish the goals of the software. For example, a program which tries to identify when a person is pointing and what they are pointing at could take on a very different strategy than that which identifies sign language symbols. And of course, analyzing mouse or accelerometer input has distinct differences over image-based methods, though they could have similar components. Roadm (talk) 03:47, 13 February 2008 (UTC)
I have added a number of references on gesture recognition based on hand tracking and hand posture recognition. Since many of the algorithms differ in various respects, the main technical information is in the articles, however. More work can be done in other areas, in particular on adding references on measurements of head pose and gaze direction. Tpl (talk) 10:50, 20 April 2009 (UTC)
citation for "gorilla arm"
The first sentence of the "Gorilla arm" section sites a blog posting on ZDNet. However, the entirety of that section of the Wikipedia entry is almost verbatim from the Jargon file. (The relevant Jargon file entry is here.)
The ZDNet posting does link to the Jargon file. It seems that the Wikipedia section ought to at least reference the Jargon file directly, and probably ought to be in block quotes as well, given that the text is almost identical. ows (talk) 20:39, 4 November 2008 (UTC)
- I too, am hunting for any REAL evidence or publications on "gorilla arm". Seems like myth. Artists have been painting on vertically mounted canvases sitting down for centuries (since the dark ages) and for millenia standing up. While it *is* possible someone somewhere once designed a vertically mounted touchscreen with poor ergonomics, that doesn't warrant perpetuating myths on Wikipedia.

- Google is your friend. Several researchers have found the effect in their work, especially research around light pens in the 70s  Apple claims to have reproduced the same findings with vertical touchscreens in laptops. I have no access to the papers with the hard facts, but they certainly seem to exist. Diego Moya (talk) 10:42, 25 November 2010 (UTC)
- The "gorilla arm" section has not been updated since user ows pointed out that it was lifted from the Jargon File. Since plagiarism is not a good thing, I'm altering the section's wording and adding a citation for the jargon file page until someone comes up with a better way of handling it. 18.104.22.168 (talk) 16:08, 19 April 2011 (UTC)
