I have released the Smoothboard software that is targeted at actual use in lessons and presentations with the focus of ease-of-use.

Smoothboard now comes with built-in annotation feature, quick access toolbar and more for all your interactive whiteboard needs.

Smoothboard can be downloaded from http://www.smoothboard.net



Following from benpaddlejones request,
http://www.wiimoteproject.com/project-ideas/mouse-smoothing-a-new-challenge-for-the-programmers-t1003.0.html
I have modified Johnny Lee's Wiimote Whiteboard 0.2 to incorporate the mouse smoothing effect. This feature enhances the smoothness when drawing with an infrared pen.

I have followed the method used in the Java version of Wiimote Whiteboard by averaging out the past values of the click coordinates.







Comparison of the original without smoothing with the new smoothing feature


Smoothing can be enabled/disabled and also the number of past points to average out can be chosen.

Update:
I have made the app to save the user settings for the smoothness so that the settings can be loaded in the next run. The settings are saved in calibration.bat.

Update on 7th June 2008:
Cursor control did not function in Vista 64bit.
I have followed the solution by takai which can be found here:

Note: I have developed a more functional version of the wiimote whiteboard. Multiple Wiimote support, outside screen toggles(right click, double click, keyboard presses, launch files), partial screen area calibration, calibration viewer, IR sensitivity settings etc.

Can you please post up the source for this, even in its unpolished state.

Somehow it does not work with Windows Vista.

I can calibrate and the programm can see the dots but the mouse doesn't move.
But I have the same problem not only with your version but on the original 0.2 version as well.

Can you please have a look on this problem?

Ive had issues with the WiimoteWhiteboard 0.3 (written and posted by someone else) under Vista.

Ill give this version a go when i get home, but seeing as i can run Johnny Lees 0.2 and this seems to be a relatively minor modification, i cant see why it wouldnt work.

Maybe try pointing the IR pen at the camera directly to test.

Does your app need the wiimotelib.dll to be present in the folder with it?

I just put you app next Johnny's so the wiimotelib.dll was already there?

Wondering if this could be Der Wichtel issue?

hm...I'm not sure what's the cause of your problem. Like you said it may be due to the code change of the mouse simulation from 0.1 to 0.2. I have not tested with a Vista machine yet.

Anyone here have successfully use 0.2 or 0.2 with smoothing on vista?

Thank you so much for that version boonjin.

It worked just fine for me and I was able to use it in some presentations already. Well done and great work!
As you are more experienced with the Whiteboard than I am.. Is there a possibility to have an IR Pen which has a bigger range as the regular ones?

I'd love to just point with my pen on the whiteboard from 5-6 meters away.
Do you think thats possible?

Hello! Glad that you have tested this version.
I am actually a new wiimote whiteboard user. I just made the IR pen only more than a week ago. I have actually not tested it on a real projector yet.

For your suggestion, I think it will be difficult because the usual IR pen does not act like a laser which is unidirectional. The IR diode will spread the IR at a considerably big angle. Another problem will be that the IR is invisible to our human eye. So you will not be knowing where you are pointing.

 Maybe there are other methods available like using a red laser pointer with a hi resolution webcam.

I will try to think of other solutions such as using an additional wiimote at the screen facing the user.

Thanks for your suggestion!
