Wiimote Finger Tracking / Re: finger tracking with led finger lights
« on: January 27, 2011, 07:10:19 AM »
Hello, i was just wondering if anyone had thought about swapping the leds in something like this with ir leds to use with wiimote finger tracking. I ordered a set and some ir leds online and i'm hoping that it will work. also i did notice someone using these to make an ir pen for a multitouch whiteboard.

I think it will effect the gameplay because removing LEDs kind of narrows the angle of radiation in some direction.
Look for a cheap wireless sensor bar to be on track.

A 9v battery works well with a 7v sensor bar, for me there was no problem with over-powering.
Add your usb cable to a wireless sensor bar (I did it with a Speedlink wireless sensor bar) most of these
sensor bars are 6v (4x 1.5v batteries 6 LEDs) for me it works fine.

Many thanks RonnieJi- Please put me on the list.
My email is on its way  :D

Nice idea!
Do you think someone could use it for stuff like that.



I have a tick for augmented reality  ;D

No, but I tryed something like that and I decapitated the LED.
Now the wiimote can see the LED all over the whiteboard but
you can only click things, drag isn't working. I think total radiant flux
is bad. Its really frustrating.  :'(

Nice design. Where did you get the foilbutton switch?Did you make that also?

Found it here Artikel-Nr.: 709905 -LN

Edit: Because tracking with the backwards facing LED is not that good I will try something like that-

Thats my IR-fingertip ;D The idea is not new but I have never seen someone has really made
one. Its built up from a foilbutton with pressure point, a clear polythene sheet as skeleton and
a lot of hook and loop fastener. The IR-LED is mounted backwards facing above the fingernail.
It works nice and makes a real "touch screen feeling". When I have painted the foilbutton white
I will try to show you a short video.

A pic of my IR-pen, IR-spray can and the "wii-slate".

The "wii-slate" works but its a bit bulky  :'(
And like benpaddlejones told you- "Piggyback a ink pen to your ir-pen" is a must.

Thanks benpaddlejones!  :)

Something from Youtube.


I am longing for the paint program and the brushes he used  8)
Looks like he tracked an IR-laser dot  ???

Programmers Den / Help for a sound program
« on: February 11, 2009, 11:04:55 AM »
I have build a spray can for the wiiwhiteboard (something like the WiiSpray but IR based).
It works fine but I failed to implement the spray sound. I would like to hear a looping spray sound
when the left mouse button is pressed  and the sound stopped when the left mouse button is released.
I am a n00b when it comes to programming, but from reading that I think it should be possible
with Java.
For now I have made a nice looping spraysound.wav with Sound Forge and downloaded
and installed NetBeans IDE 6.5 but to start the application program I am totally lost  :'(
Can someone help?

Thanks for reading (and sorry for my english) Katkind

Thanks benpaddlejones!
Yep- Graffiti Studio 2 works fine with  Boonjin's Smoothboard.
I tryed a gift card and it didn't loop. No chance to integrate the sound into the can  :'(
I think sound should be integrated into the wiimote software. With Java it should be
possible- There are routines for looping sound with a mouse click. I know some
application programmers have issues with sound, but I think its a chance to show how
smart wiimote whiteboard is  :)

Thanks Katkind

I was just speaking to a teacher about how the IR-Pen can be a design and technology project this is exactly the evidence I need!

What we need now is a graffitti painting application!

You can buy gift cards that you record a message in. When you open the card the recorded message plays. Rip out the electronicsm, record a spray can in action and wire to your switch.

benpaddlejones :)

Thanks benpaddlejones.
This one plays constanly but it's 79.95 EUR  :o
Do gift cards play constanly?
Oh- And there is Graffiti Studio 2 but didn't work for me  :'(
