Hi there,

I was just wondering if it's absolutely necessary to use a wiimote in the project. This probably sounds really stupid, but my point is that wiimotes are nintendo-brand. Per definition that means that they're outragously expensive for the hardware that's actually in there. If all you need is a IR receiver that shouldn't be too hard to find on the online electronics market, right?

Cheers!

It has an IR camera. Not just an IR receiver.

Thanks for pointing that out, I had no clue Smiley. It's not really an answer to my question though. Are IR camera's readily available on the electronics market?

There are ir cameras on the market, some (not many of the quality of the ir camera in the Wiimote) that can be purchased for less than a Wii Remote. However there are some major issues that make the Wii Remote a much better option.  shakespeare1212 wrote the following as I thought his explanation was pretty clear:  

"While using a web cam to track IR points of light can work, it puts a much greater load on the computer then using the Wii Remote. You see the Wii remote sends back to the the computer a nice little data report, you could think of it as text, and in this report it has the x and y possitions of each of up to four points or IR light that the wii mote is currently tracking. Now all that the software has to do is calibrate this information and use it.

On the other hand what a web cam sends to the computer over a USB 2.0 connection, ussually is 30 frames per second of video informaiton. For a 1.3 or 2 mega pixel camera this can be just a HUGE amount of data. Then you have to write a program to sift through all of that data, find the IR points of light and then do something with them.

That is why we all love the Wiimote. It is a little processing work horse. Although computers are getting faster all of the time and someday, yes, it may be time to say bye bye to the beloved wiimote. For now, it is the very best way to create an interactive white board, by far."
