Wiimote Smoothboard / Different use of multiple wiimotes?
« on: November 14, 2009, 10:01:09 AM »
My problem with the wiimote whiteboard has always been that students do not understand that the IR camera needs to see the dot and they can't stand in front of it or block it with their hands.

To combat this, I'd like to mount the wiimotes at a more extreme angle on either side of the board looking down.  The obvious problem with this is that they will never be able to see the lower corner of the side they are mounted on, and as such I will never be able to calibrate them using the current method (calibrating each wiimote separately).

My question is if it would be possible to skip points that were not visible to the wiimote during calibration, so instead of clicking an X in each corner it would have an X in 3 corners and one in the center, or something like that.

Here's a picture of how I'd like multiple wiimotes to function, perhaps it's already possible and I'm just doing something wrong.

I teach honors chemistry and I constantly use this program from texas instruments:

It is a flash debugger for the TI-83.  It's designed to help write programs for the calculator, but it essentially allows you to use the TI-83 projected onto the computer screen.  Used in conjunction with the wiimote whiteboard it allows students to learn which buttons to press and when, instead of just saying it to them, you can show them.

Pretty sure this is a known issue with blue soleil 6, and a fix is in the works.

BoonJin, this looks amazing.

The one thing that I'd love to see implemented in a windows environment is the ability to use multiple wiimotes.  It has been implemented in both the Linux version and the Mac (Java) version, but I haven't seen it in a good ol' windows environment.

Basically, the problem is this:  I use my wiimote whiteboard in my high school classroom... mostly in my Chemistry Honors classes.  My wiimote is mounted centrally on the ceiling and does a pretty good job "seeing" the screen.  However, sometimes students will stand directly in front of where they are trying to write blocking the IR camera completely. I'd like to be able to have 2 wiimotes "seeing" the screen at all times, so even if one is blocked by a student the other will see it.

Here's an example picture.

I stand on the chair that's right below it every morning to sync it :)

Hmmm... I hadn't checked these boards in a while.

Anyways, it's the summer right now so I can't take a picture in the room.  The setup is fairly simple.  I bought one of those gorilla pods from best buy, mounted some velcro on it and attached it to the ceiling using folder clips... it sounds ghetto but it looks pretty nice and works like a charm.

I'm probably going to stop by my classroom in about 3 weeks, I'll take a picture of it when I do.

Wiimote Interactive Whiteboard / Re: Needs pen advice for class demo

You need a 1.5v battery (all normal batteries are 1.5v, that includes AA, AAA, C, and D).

1. Connect a wire to the - end of the battery and attach it to one side of the LED.

2. Connect a wire to the + end of the battery and attach it to one end of a momentary push button switch, attach the other end of the switch to the other side of the LED.

3.  ??????

4. Profit.

P.S. If you turn on your cell phone camera you'll be able to see the IR light from the LED when you push the switch.  If you don't see the LED turn on just swap the sides of LED that you connected the wires to.

I'm currently adding this feature to my java whiteboard app.
I will be considering two cases:

1. Using multiple Wiimotes for redundancy (each Wiimotes sees the whole screen)
2. Using multiple Wiimote to cover a large screen (each Wiimote can only see part of the screen)

I just started this but got a prototype working for case 1 with two Wiimotes.
I haven't released anything yet.


Awesome! Let us know when it gets released! Thanks!


It seems to have the perfect whiteboard system, using 2 wiimotes (less loss of signal?). It has the ability to track when the pen is touching the screen, no pressing buttons to turn the light off and on.  Anyone thought of using a system like this in place of the wiiwhiteboard?

IR Pens / Re: Best Led for Pen

I have tried several LEDs the radio shack are very weak and no great for the pen.
I had so much frustration with rs LED  stay away if you can.
the Jim-pack brand are as bad for Led pen as Radioshack ones.

Not trying to be a jerk here, but didn't you make a post that said something like "the radioshack LEDs work just fine, don't listen to what others say"?

I'm quite sure that you did...

Here it is:
for all you that have problems with the radioshack LED
they are actually good.
I have mine with a 1 aa bat. non resistor

Curious, LED means Light Emitting Diode.
So the should emitt light....

I believe it says "use with XXXXX LEDs"

It's not a cheap option, but Microsoft OneNote is probably the best whiteboard program out there.  It has all kinds of pen options, drawing options, the notebook/folder capabilities are incredible, and saving is automatic.

As far as I know the wiimote is watching the reflection of the IR light off the screen, not the actual IR LED.

There seems to be no problems with tracking, but I do have my wiimote mounted to the ceiling pointed at the screen.

Wiimote Interactive Whiteboard / 0 Learning curve durable light pen
« on: March 08, 2008, 10:20:23 PM »
I'm a high school teacher, and I always use my own tablet PC to give notes in my class.  I am not comfortable letting my students use my tablet PC, so the wiiwhiteboard is a great way for kids to be able to work things out on the board.  Anyways, I needed a cheap, durable light pen that works like a pen should work, not like a stick with a button.  Here's what I came up with.

It's a short piece of PVC pipe capped on both ends, one end has a Radio Shack toggle switch with the cap removed.  This means that when someone makes contact with the white board surface it activates the LED like a toggle switch would (the button is very loose, so it doesn't scratch up surfaces).

This pen costs about $4 when all is said and done.

Here are some pictures:

Wiimote Interactive Whiteboard / Possible to use 2 wiimotes?
« on: January 28, 2008, 04:21:31 PM »
So, I've started using the wiimote whiteboard in my classroom, and I love it.  However, some of my students do not fully comprehend the fact that the wiimote has to be able to see the IR pen.  Sometimes they stand in front of the wiimote and their writing gets broken up where the wiimote loses track of the IR reflection.

Would it be possible to use 2 wiimotes so even when they stood in front of one the other one would still be able to pick up the IR reflection?

I am not a programmer and don't claim to be, but this seems like a great idea that would make the wiimote whiteboard much more practical to use.
