Gotcha. I actually understood what you were saying, and your reasoning. I wonder if having that many lights might hurt the effect from the light spreading?
I could see using a band, but it seemed more practical to just have 5-6 lights on the corners and sides of the front of the remote. I still can't ever see a reason for having it on the bottom.
Also, I would not track the nunchuk at all in that manner, and just have Wii-motion+ level movements. The reasons are pretty obvious.
1)Design of the Nunchuk is needlessly complex, and sliding your and into a a holder like that can be comfortable and may not fit for others. Keeping It Simple is better.
Well the nunchuck design was created as it was being drawn. originally I was thinking of just extending the top and bottom of the nunchuck, but that looked kinda stupid, so I turned it into a "brass knuckle" design in stead. it could be used to have a different IR strip set up to make separating the wiimote from the nunchuck easier for the camera.
2) Games that are using the Nunchuk for the Nunchuk properties IE analog stick and additional buttons, and some movement won't need the same advanced movement options already in the Wiimote 2.0 However, if you did need that set up for a game 2 Wiimotes is already plausible.
Think of a Sword and Shield game. Zelda 2011 (Wii/Wii2 game).
You are gonna want your analog controls still, so tracking the nunchuck properly would solve the need for having to shoose on whether you have a second pointer or having an analog joystick. The only time you should need to use a second Wiimote should be when you need a single player to use 2 pointers (dual wielding independent pistols maybe?) Having the Nunchuck tracked too is keeping it real simple for the user. You have everything you need out of the box.
Yeah, I agree that Nintendo needs to perfect the controller with Wiimote 2.0 Though, I think it needs to be done in the smartest way possible. Though the one thing that would be cool about your light strip idea is each new player could be given a different color light that would help identify the controllers easier, and look cool.
Can you do differently colored IR lights? I have been assuming that you can, but I didn't really think about that aspect. I wasn't thinking of different colored LEDs that you can see, I'm talking about the invisible lights like in the sensor bar. If your not sure what I'm talking about, turn on your Wii and look at the sensor bar through your cellphone camera (there are 10 lights on there, 5 on each side).

although it lighting up in pairs would be pretty damn cool too. Especially if you can choose the color like on Move, but only having the color strips on each controller lit up, not a giant glowing ball.
There is no reason for the Nunchuck 2.0 to not be tracked by IR light if the Wiimote 2.0 is using it. It's cheap, it's effective, and could do away with the need for a gyroscope entirely.
gyroscopes still needed. could do with out the cord though.
