Where would I find Cam2Pan, I keep hearing about it. Then I found MouseVision.com where it should be, but I keep getting erros saying its down.

Is it just me? Or is the site down and I missed something in my search. Or was the site moved, or taken down all together?

Thanks in advanced.

Try Free-track; I gather it's better. I've downloaded it and bought a cheapo web cam, but have yet to get 'em hooked up and running--my next project!

I've used cam2pan and freetrack, freetrack is definately better, though needs an led light source to track.

Another option is Cachya http://www.cachya.com/esight/overview.php which uses a paper target to track the head movements. I've not tried it yet but have heard it works well.

I'm in the process of getting together the parts to make a 3 point infared led head tracker for freetrack, I've used it with a normal led head torch and it worked ok, but had problems with it picking up reflections off my glasses and headphones.

Thanks, I like the idea of tracking your movements with paper.

Still though, does no one know what happend to Cam2Pan? Lol, everyone who plays Flight Simulators has at least heard of this. But it disapears without notice? :/

Inadaze,
If you're getting "interference" from reflections from glasses, etc., that would seem to be because your light source is not bright enough to allow you can set your camera's exposure and/or gain low enough to block out virtually all other sources but the LED. Either that or your camera just can't be set so as to give what amounts to an almost black image (severe underexposure).

Have you tried a small penlight replacement bulb? The best is the type with a hemispherical dome which casts a quite even pattern of illumination over more than 180 degrees. This allows almost unlimited head movement, whereas LEDs (the clear and hence brighter ones, mainly) tend to be rather directional or have signifivant fall-off beyond about 10-20 degrees off-axis.

You should be able to find such a bulb in any DIY store or other place which sells a variety of flashlights. The ones I've used for small home-made planetarium projectors were made for either 1 or 2 AAA or AA battery powered penlights. To save on batteries, get a "wall wart" power adapter which supplies either 1.5 or 3 volts (appropriate for 1 or 2 batteries, respectively.) If you wear headphones--assuming they're wired--you can run the power cable along the 'phone's cable.

Incandescent bulbs emit about 85% of their energy in the IR, thus making them quite useable with web cams having IR pass filters in place, such as developed film, etc.

Hi Lurch, yeah, I've ordered some 5mm ir wide angle leds to use that should solve it. (They should arrive tomorrow with any luck http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif )

I can set the camera to almost black so when I look directly at it it can pick up the head torches led ok with no reflection trouble, but as soon as I turn my head the angle of the led means the camera loses the track because of the narrow beam from the diode I've been using. (It's a head torch I use for fishing and pretty expensive so I don't want to wreck it by sanding the led for a wider angle). To get around that I had to turn up the exposure, hence getting reflection problems.

I'm going to grip the other parts I need tomorrow, resistor, battery strap, 9v battery etc (I want the unit to be cable free like my headphones, because I have a habit of forgetting I'm connected and dragging everything out the socket when I leave my puter http://forums.ubi.com/images/smilies/35.gif) I fancy trying the freetrack 6dof set up any way for BOB2, and plan to mod the camera by removing the IR filter from it and adding a piece of floppy disk.

Thanks for the advice though, I'd sorta come to the same conclusion by trial, error and faffing about http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
