Hi All,

I've been following with some interest the work on the Camera APIs, and I'm slightly concerned that you may be missing a class of user of that API who have their own requirements which don't appear to be met by some of the proposals so far.

I'm interested in doing augmented reality type applications in HTML5, similar to how FLARKit works in Flash (http://www.libspark.org/wiki/saqoosha/FLARToolKit/en). Presently I'm working using VLC streaming and a proxy, which isn't really an option for most end users.

I believe the best way to do this is to have access to the video output of the camera. This requirement appears to be met by the Google Gears proposed spec (http://code.google.com/p/gears/wiki/CameraAPI), but doesn't seem to be a priority in the "upload"-type proposals.

Having said that, I think that approach (1b) in http://lists.w3.org/Archives/Public/public-device-apis/2009Nov/0132.html could possibly work for me, but in my case I'm not at all interested in the upload capabilities. I suspect the browser UI for that ("Upload an image or video") would be somewhat unsuitable.

The general approach proposed as (2) in the above link would be much more suitable for my requirements.

Anyway, I realize this is early in the process, and perhaps this feedback is premature. I hope that it can be of some use anyway.
