When running the Calibration program, I can get the first two dots OK, but no matter what I do, I can't get the third and fourth ??!??  I have no idea what to try next.  The first two are found very easily, so I know the light source is good. 

Any ideas?  Thanks very much!

Make sure you're not going out of the field of view of your wiiremote.. the wiimote has only a field of view of 45 degrees..
Also check the Wiimotetest application, if will show you exactly where your ir sources are according to the wii remote.. then you can see  if you're going out range Smiley

I'm using this gadget http://www.gifteurope.com/fiche.asp?i=1866, but I'm having trouble calibrating.
When I click the first calibrating-point, the wiimote detects two (sometimes even three or four) clicks. So first I assumed that this had something to do with the pen, but when I film the pen I only see one blink of the led every time I click.
So what am I doing wrong? (I've tried it on my laptop, next week I'm going to use an LCD-projector)

Thanks for the suggestions.  I will try Wiimotetest and see what it says. Not sure what "going out of the field of view" means ... Say I'm projecting onto a screen, and the Wiimote is pointing at the middle of the screen. If it is pointing at the middle, and can react to the top two dots, it should react to the bottom two as well, right?

I didn't think about the resolution - could that really be it?  I was running higher than 1024x768. Huh

Maybe there is some reflection from your screen, do you use a CRT or LCD display?

Make sure your hand isnt in front of the wiimote, place the wiimote to the side about 40degrees, if your right handed place it on the left and if your left handed place it on the right. This way you can almost be sure that your hand isnt blocking the signal.

I am having a similar problem.  When I go to calibrate, I get the first cross hairs in the upper left corner.  I use my pen to calibrate, then I do not get any more crosshairs.  They do not show up on my laptop or my projector.  What am I doing wrong? 
Thanks

Sounds like the calibration program doesnt know your Resolution, so the crosshairs are of the screen, strange.

the calibration app just get screen area, it should have no issue with odd resolutions.

if you have multiple monitors and they are at different resolutions then it maybe trying to use a larger "screen area" than your main monitor is showing.

you can go into the calibration form and manually set the screen size to your resolution and see if that works for you. otherwise just set the text of the panel to be the resolution that it reports and see if there is an issue.

the way it puts those marks on the screen is a certain percentage of the resolution in from each corner, thats how it can handle multiple res'

once again, what res do you run at and how many monitors do you have on? (and by on i mean maybe you have extended your desktop to another monitor out jack and just dont have a monitor plugged into that jack, like if you have a laptop or a dual output card. check it out in your display properties)

So the program has to know your resolution.
What is the whole thing about the ir camera having a 1024 x 768 resolution camera. Does it mean that it is the best if your laptop screen is with this resolution ?

And also, how can the camera successfully track points in larger screens, like projected screens, with huge resolutions ?
