Topic: Need help finding tracking ball for Wii

My ex wife has a Wii still, and my daughter likes to play with her sisters there (mainly Just Dance games), but would like to use the tracking ball instead of remotes. I bought a tracking ball online (Ubisoft Hercules USB WC04 webcam) but it doesn't work. I have looked online but can't find anything that tells me what product to use for tracking.

Does anyone know what camera / sensor to buy so they can play Just Dance without the remotes? And if you have a link, that is greatly appreciated. Thank you!

Maybe @Anti-matter might be able to help if he's still around I believe those are his type of games.
