Hi everybody !
First, I'm sorry for my english, I'm French and young : my english is not perfect. 

I've seen somes videos about "Wiimote Whiteboard" and I think this is interesting.

But I'm not sure to understand everything... (I'm sure I don't  )

The trick is :
- The Wiimote is connected to the PC with Bluetooth. Look at a surface. (Whiteboard for exemple)
- The PC is connected to a Video Projector which send the Desktop image on the surface.
- We use an IR Pen to "write" on the Whiteboard, the Wiimote receive the IR Pen's position.
- The Wiimote send the information to the PC with the Bluetooth
- We use an emulation software to recognize the information gived by the Wiimote as a "cursor".


But I've got some questions, I've read some dock on website, but the English is not very easy for me...

- How the Wiimote understand when we're touching the Whiteboard and when we're simply moving the Pen in the air ?
- This doesn't work with every programs ? If it works like a "second mouse", it should ?
- How the relation between IR Pen and Wiimote does work ? The Wiimote has to see the IR Led ?
- Basically, when we're playing Wii, it's not the Wiimote that "send the position" to a captor ? Because, here, It's the IR Pen that send is own location to the Wiimote... I don't really understand.


So, I like this idea, I don't know if I'll try to do this at home (I don't really need) but I really want to understand the trick. 
It would be great if somebody could answer me. After research, I don't find the answer for those questions, or the answers were ambiguous.

Thanks ! Have a nice day (It's 7h30 at home :p )



PS : Again, I'm sorry for my english, tell me if there's "Misspellings" or other wrong things.

Hi Asuka
I'll try to keep it simple.

I won't hold it against you even though when I was last in France they arrested me for not having a visa!

Yes!

Me either, I'm Australian

It doesn't. If you have IR-Pen away from calibrated surface (whiteboard) will give incorrect location.

It works exactly like a mouse. Will work in nearly every program. If you find one that it does not work post your problem to this forum and we will try to solve it.

This will be difficult with language barrier, here we go:
Wiimote has a very special camera that can detect light and track light in space. The filter (red plastic on end) filters light so only light wavelength of 940nm can go through filter. The Wiimote is capable of detecting 4 IR-Blobs at once.

Nitendo Wii:
Works by holding Wiimote, the Wiimote follows the IR-Light from the sensor bar as Wiimote is moved in your hand and sends information back to Wii console and you play game.
Wiimote Whiteboard:
Wiimote is still and IR-camera is calibrated to surface. If camera see's an IR-Source (your IR-Pen) it calculates IR Location then sends to computer via Bluetooth. Software converts this message to location on screen and runs the command (usually right mouse click).

As I said I'm Australian who am I to correct your English, mine sucks too

Hope this helps

The pen is made with a "momentary switch" so the IR-Led is only illuminated while the switch is pressed. Depending on what cursor control you have selected (left click, right click, cursor motion only) your computer will register that cursor action at the location at which the IR-source is detected. All the Wiimote Whiteboard applications are single cursor, so if multiple IR-sources are detected the cursor will bounce between them.

How to open a folder on your desktop and maximise with cursor control set to "Right Click":
1. Move IR-Pen over icon, touching calibrated surface.
2. Click & release switch on IR-pen
3. Click & release switch on IR-pen
Your computer moves the cursor to that location then registers 2x slingle left clicks on that location close enough together clasiifying it as  a double click, executing the application.
4. Move your IR-Pen to the top right 'Maximise button' on the aplication window & touching the calibrated surface
5. Click & release switch on IR-pen
Your computer will then move the cursor sitting over the icon, to the location of the window maximise button then register a single click, maximising the window.

Does that make sense?
