Camera Nokia n810 and OpenCV

Hello!

Unfortunately, we have got some trouble with using camera of Nokia n810 with OpenCV library. To get camera stream, OpenCV uses the following function:

// index – number of device to get video; initial point is 0.

CvCapture* cvCreateCameraCapture( int index );

/*

 *devices are sorted under the list:

CV_CAP_ANY      0

CV_CAP_MIL      100

CV_CAP_VFW      200

CV_CAP_V4L      200

CV_CAP_V4L2      200

CV_CAP_FIREWIRE      300

CV_CAP_IEEE1394      300

CV_CAP_DC1394      300

CV_CAP_CMU1394      300

let us suppose that the first camera is CV_CAP_ANY, the second is (CV_CAP_ANY+1) by analogy for cameras with fireware interface: the first is

*/

If we use call of function with indexes:

/*

CV_CAP_FIREWIRE      300

CV_CAP_IEEE1394      300

CV_CAP_DC1394      300

CV_CAP_CMU1394      300

*/

then application runs on Nokia n810, but there is no video stream. Could you give us some piece of advice, what kind of above-listed devices is camera of Nokia n810? And what is the preferable device index to use in program for correct capture of video stream?

I've been looking lately at

I've been looking lately at attempted to use the n810 camera as a mouse.
Here's the basic idea.

The n810 camera, while low quality, should work fine to notice and track gross finger movements across the screen.

This would be handy for scrolling motions such as in the browser/microB.

Here's how I would expect it would work. A background process would watch the camera and notice wipe like motions (up / down / left /right) and translate them into events, either keyboard or touch screen equivalents.

Has anyone seen a project like this in the past or have suggestions for how to proceed?
