GlovePIE
There are several free programs on the internet that make it possible to interface your Wiimote with PC applications. I used a program called GlovePIE. It takes some time to understand the functions of the program because the documentation seems to be written for people that already know GlovePIE. Also the copyright disclaimer is really strange. But after investing some time to learn the functions of the programm and going through many examples and forums on the internet I found it one of the best solutions currently available. Actually real good solutions do not yet exists.

GlovePIE has no function to send messages to a RS232 port. So there my Visual Basic skills came in handy again. I made a small programm that translated Winsock data to the serialport. I made a GlovePIE script that uses the OSC (Open Sound Control) labraries. This is no more than simple winsock messages.

This is the my GlovePIE script:

ExitScript = HeldDown(Wiimote.Home, 3s)

var.broadcast = false
var.ip = “localhost”
var.port= 51345

// roll to select color
// pitch not yet used
// values from -90 to 90
var.N = wiimote1.smoothpitch
var.M = wiimote1.smoothRoll
debug = var.N + ” ” + var.M

// Red
if ((var.N >= -90) && (var.N < -30))

var.strR = (255*(var.N + 90))/60

elseif ((var.N > 30) && (var.N <= 90))

var.strR = 255-((255*(var.N – 30))/60)

else

var.strR = 255;

endif

// Green
if ((var.N > -90) && (var.N <= -30))

var.strG = 255-((255*(var.N + 90))/60)

elseif ((var.N >= -30) && (var.N < 30))

var.strG = (255*(var.N + 30))/60

else

var.strG = 255;

endif

// blue
if ((var.N > -30) && (var.N <= 30))

var.strB = 255-((255*(var.N + 30))/60)

elseif ((var.N >= 30) && (var.N < 90))

var.strB = (255*(var.N – 30))/60

else

var.strB = 255;

endif

//debug = var.N + ” ” + str(var.strR) + ” ” + str(var.strG) + ” ” + str(var.strB)

var.strR=chr(var.strR)
var.strG=chr(var.strG)
var.strB=chr(var.strB)
//if wiimote.a then

sendosc(var.ip, var.port, “serial”, “C”+ var.strR + var.strG + var.strB + chr(0xff))

So the GlovePIE script sends winsock messages to a visual basic program that sends RS232 messages to the Moodvision controller.

Color Algorithm
I have been playing with many different color algorithms to get the best results. Interesting was the version in which a had defined 3D area’s in which one discrete color was active. I ended with the version shown here. Basically I split the range from -90 degrees to +90 degrees in 3 sections. In section 1 green goes from 0 to 255. In section 2 green goes from 255 to 0 and blue goes from 0 to 255. In section 3 blue goes from 255 to 0 and red from 0 to 255. This way I could make any color and also have smooth transitions between them.

If you wish to contact me, check the contacts page.

If people from Nintendo read this, I really would like to see your development department sometime and dicusse some great ideas I have!
