3d Head tracking without Wiimote

This video shows preliminary results of my Google Summer of Code project of new human computer interfaces. This one shows 3d head tracking interaction with OpenGl.
For more information, please check http://code.google.com/p/ehci/
The web cam view is all the program gets as input to detect 3d head position.

Hi Mr. Irvick. I'm glad for your comments.

Well... the code is still in alpha, so I really expect some bugs, but in case you get it OpenCV working correctly, this should be enough.

Can you post a bug report in EHCI google project, at code.google.com/p/ehci/issues/­list please?

Best regards,

Daniel

Hi, Smithers.

Have you checked if your webcam is OpenCV compatible?

Please check the opencv wiki at willowgarage (I can't post the link here, but just google for these terms)

under 'Windows Compatible Cameras'

Which is your camera, by the way?

hey i downloaded your demo for windows. i also have C++ 2008 installed. but it doesn't seem to run...

i select my webcam and then it opens up 1 command prompt, and 2 windows which do nothing... is it compatible with vista 32 bit?

[dannyxyz22]

Hi Smithers,

it is surely compatible with vista.

The two windows you are seeing should be the ones that are in the video. It's weird though, that you don't see anything. It seems your webcam is not capturing frames. Can you post your webcam model and installed drivers?

Have you tried the other applications?

Thank you a lot,

cheers!

Hey there. This is one of the most impressive demos I have seen. I am trying to play around with the code, however I got 6dofhead to run (and it is _amazing_) but this demo just dies with "Error allocating memory for color-corrected image data"

From looking at your source it seems like it is not getting any data from my camera. Ideas?

[SMITHERSTHEMAGICIAN]

nope.. still same problem :(

[SMITHERSTHEMAGICIAN]

i am going to try downloading opencv.

will tell you if it works :)

[dannyxyz22]

I mean... try running the program with the camera facing your head, like you'd normally use it for a web video conference.

Thank you,

Hi Smithers :)

Yep, you've got it, it's OpenGL. But one of the windows (the smaller one) does not use OpenGL for rendering.

I suggest Installing OpenCV (google for it) and see if you can run the samples. The procedures for creating and showing the grabbed images are the same.

Try to put your face in the webcam. It might also be waiting for a face detection to start displaying everything.

[SMITHERSTHEMAGICIAN]

okay its opengl... i have tried using different cams but it still does the same thing...

[SMITHERSTHEMAGICIAN]

yea it works with everything else and other tracking programs.

3 windows open. 1 empty command prompt (can't type anything in there)

1 small grey window

and 1 big empty window

how does this render?

opengl?
