processing and Wii Controller!
Feb 10^th, 2009, 1:13am

Hi there.
I am working on an installation and after a research I've made I'll propably use the Wii remote controller as an interface of interaction.
One main aim of the project is as the user points the wii remote and moves it in x,y and z axis to get feedback of the position of it in the room.
As I saw I can use a Wiii Sensor bar (1or more) and the wrj4P5, WiiRemote P5 Library.
My question is, will the library return me values of the x,y,z ayis as they change while the user moves the wii remote form left to right or from bottom to top?
Thanks in advance!

hi nikolasgr

my previous work is detecting 2d position of an irLed on a screen by the translation from a a quadrilateral to a rectangle with one remote.
like jonney lee's low cost whiteboard
http://www.geocities.jp/classiclll_newweb/JonnyLeesBoardEmulator/applet/index.html

i'm working a project detecting the 3d position of an irLed by the traiangular analysis of two remotes.
like
http://www.youtube.com/watch?gl=JP&hl=ja&v=CT6aQN-lwmo

it is easy to analyse with the known position of two remotes.
but, it is rather hard to estimate/caliblate the position of two remotes.
the first sketch will be published in a few weeks.
the second sketch will be published ina 4 or more weeks.

is my project useful for you?

Hi again!

Yes I got many new information that will help me with my project.
The basic aim is to move the wii controller or a led in the finger and to have the exact position of it in x,y and z ayis. That means on the horizontal and on the vertical dimension.
I found it very interesting to install two wii remotes and just to move a led in the room and track it. Can I somehow get the exact position of the led in the space in relation to the (0,0) point of the horizontal (x) and vertical (z) axis?
I need to now the angle between the(0,0)in both xy and z axis and the led(or wii remote).
I just made my own wii sensor bar and I own a wii controller too. I can not find the library "wrj4P5", that makes possible the connection between wii remote and processing anywhere for download.
And are any examples available where I can make some experiments and see how it works?
Thanks!

i don't know the exactness you need is.
the ircamera of a remote has 1024x768 precision. it will be correspond to exactness, and it's focal distance, view angular, too.
my project has not so much interest on the exactness. but some experimentation may give you the value of these parameters.

yes you can get (x,y,z) on the orthogonal coordination, and you can set the origin at arbitrary location in a room space with the ordinary translation and scaling.
btw. does your "angle" mean the angle between the irLed's location vector and each axis if so, of course yes.

i'm sorry for no request to the P5 team for publishing my lib, and i'll do after some preparations.
currently, you can download and/or read reference from
http://sourceforge.jp/projects/wrj4p5/

for the install process, the following was published with some english native guy.
http://www.brockcraft.com/category/wiimote-work/

not only wrj4p5 but my all sketches, the following are my scrap yard.
http://www.geocities.jp/classiclll_newweb/

and finally
the following is my (japanese) blog page mentioning this topic.
http://blogs.yahoo.co.jp/classiclll_jp/53179001.html

i hope these are help for you.

hi nikolasgr
sorry for late. (are you here?)

although intermediate result, the 3D real pointer is here
http://www.geocities.jp/classiclll_newweb/realIR3D/applet/index.html

this sketch needs the newest libs, wrj4P5, Loc, l4p5
https://sourceforge.jp/projects/wrj4p5

next, i will try to estimate the attitudes of two remotes by some refference position.
