Release: WiiMote Control, v20080111 (0.3)

Not sure if calibration is necessary (though the circle-like output area is a bit lame, IMO. correcting that could be really helpful). If you find a reasonable method for doing this, and think it would be helpful across the board, let me know and I'll try to wrap it up in the patch itself.

Regarding getting IR reliably... hehe :) I'd love to burn more time on it, though that's not too likely in the very near future.

The framework code has fun comments like this:

// based on marcan's method, found on wiili wiki:
// tweaked to include some aspects of cliff's setup procedure in the hopes
// of it actually turning on 100% of the time (was seeing 30-40% failure rate before)

Unfortunately, as we know, it's still not 100% quite yet.. looking into this.

bare bones.

toggle calibration flag on, waggle your wiimote around, toggle calibration flag off. it will scale the detected reach of the wiimote to the comp size. critically, it should remember the calibration when the comp is saved and loaded back in.

lots you could do down this line, pairing through a structure with a calibration display render patch.

WiiMoteControl 20080301 beta - hope this helps :)

There's a newer beta which should allow this (though I've not tested extensively). You'll need to check the "I want to test new and updated patches" box in your profile to get access to it (it's still in beta, and somewhat unstable).

check out darwiin remote -- it's the underlying framework we use for this patch.

i have some code laying around some where on my leopard machine that does this. i will look for it a little later i did this for a project last year for interactivity class we where using isadora but i did a qc global midi cc conversion to get the info into isadora so i don't know if it will be much help.

the way johnny does it is he takes the fov of the wii mote creates a right triangle with the center point of the fov - half your y screen dimensions that is supposing the wii mote is on top of your monitor. then uses that trig to figure out rotation. x y and z are pretty simple. just add wii mote IR in patch settings and the use your wii mote backwards and strap the ir bar to your head.

to get a suedo z depth you calculate a distance between the first and last ir. so that is simple when the distance gets bigger that means the z depth is changing when it gets smaller then z is going the other way. you will have to fake it with your own setting or do fancy trig to calculate the real world from fov. i think johnny said he is subtracting 45 from the height of the monitor.

then x and y are simple they are the values you are getting from the wii mote all ready. getting rotation is tricky. once i get a wii mote i will have a patch done up. i am currently doing head tracking with face recognition, and AR but the wii mote can be more accurate once you get the math right.
