lol i thought using johnny wiimite whiteboard will be enough since the logic is the same right?

that nice, but it would be great that you can add more power point function in it rather then just next slide and previous slide

Wow its amazing, its a great application for those who like sound effect.

I got a few question to ask, are you using the 4 IR LED to control the sound effect? also which one control the volume etc etc so that the user can know how to control the sound effect...

Sorry I am new to theremin so i do not know much about this.

GlovePie is like a script for those who have little or no programming background to use it. If u want to use it just for wii, i think glovepie can do the job although it might not be as good as C programming cause the logic behind is not very clear, i mean the maths logic. But most of the things can be done using glovepie

well u can try it first, if no problem then its good, but if got problem which is the same as mine, then u need to edit the source code a little. If you are using boonjin application, you can ask him to help you edit the axis coordination movement. If he have no time for that, then i will use johnny chung lee source code to help you edit it

Wiimote Interactive Whiteboard / Re: i have a problem

bluetooth problem? have u tested out with other johnny application?

well u need to recalculate the y-axis, by subtracting it with the screen width then *-1.

I have tried and it works. But when my friend did this, he doesnt need to change anything and everything works fine, so i find it very weird. Anyone got any explaination on this?

oo sry i forgot to see its 2m, if 2m its alright... So the problem might be the surface of ur projector screen, well maybe i not sure cause some projector screen allow light to pass through, thus it does not reflect the ir much and it causes ur problem.

Next i could think is that u r blocking it, but this possiblity cant be high so... can forget it lol

Last could be IR source problem, change it into a new battery and test

i tried, well not using the projector screen by a few piece of paper and the projector and the wiimote is behind the paper. Well u can use plastic, but for me is just a prototype so using a few piece of paper is fine. and it can WORK!

as for projector screen, u nid to make sure that IR can pass through the projector screen, if not then it wont work.

If u put at the back of the projector screen, the movement of the cursor, y-axis will go in opposite direction. This will be the problem u will be facing. But if u know how to edit the code, it will be easy! 

well according to my experience, the larger the screen, the further away the wiimote is. But wiimote has a limited distance of about 3m, after the limited distance, the wiimote wont be able to track IR source clearly as less than 3m. sorry for my english:)

Wiimote Interactive Whiteboard / Re: Somes questions... :-)

You must use infrared pen in order for the whiteboard to work.

The wiimote is connected to the computer via bluetooth and it has an infrared camera which can detect infrared so whenever u move ur ir pen, the infrared camera can detect the location of the infrared, so by using the position of the infrared using x and y axis, the mouse cursor will be able to follow the position of the Infrared.

So the conclusion is that the wiimote contain infrared which is able to detect the location of the infrared  source...

Sorry for my poor english :)

The Infrared camera detects the leaking chemical which is so call heat of the infrared led right? Sorry for asking this newbie question just want to make sure...

Wiimote Interactive Whiteboard / have anyone come across this problem?
« on: November 05, 2008, 12:19:35 AM »
have anyone come across this problem where the whiteboard detects 2 IR point when there is onli one IR source also sometime the wiimote whiteboard detect the first ir, or should i say 1 and onli ir source as a 2nd detected ir. Sorry for my poor english, but does anyone come across this problem? and if u know the cause of this problem can kindly tell me cause i realli nid this to happen :)
