Wiimote Smoothboard / Re: Smoothboard for Mac Release
« on: February 06, 2013, 06:46:44 AM »
Dear Boon Jin,

you could at least acknowledge that you made it work on OS X 10.8 by using my solution from here:


Users with Mountain Lion (Mac OS 10.8 ) may download the latest package which should work on the operating system.

Hi Brendan,

Again, thanks for your help. How much is a coffee?

I'm glad I could help. Thank you very much for your donation, it will certainly cover the cost of a coffee :)

Hi Brendan,

java -cp bluecove-gpl-2.1.0.jar:WiimoteLogger.jar org.uweschmidt.wiimote.logger.WiimoteLogger

this command should work as suggested on the website.

I also tried repeating these commands after downloading the bluecove-2.1.0 (in addition to the bluecove-gpl-2.1.0) and zipping it.

You don't need to add the BlueCove GPL'd library to the jar-file with the zip command. This is only required for my Wiimote Whiteboard app.

Hi nym,

I put that feature on my TODO list and it may appear in the next version of my app (or the one after it). This probably won't happen very soon, but hopefully before the end of the year.

Hi nym,

Do you mean selecting a region that spans across multiple screens?

that's an example of one use, yes - but keeping in mind that a user's screen resolution in these cases is likely larger than that of the IR camera, i was thinking something more like being able to select which monitor/projection etc to control via IR pen...and moreover, which section of said monitor/projection to control via IR pen.

letting the user select a region of a single screen to use will probably be much easier to implement than allowing a selection that spans across multiple screens. That's why I was asking.

Hi nym,

one thing that no (Free) wiiboard app handles yet is multiple monitor setups OR selective screen region control. in all current incarnations, the whiteboard calibration screen covers the entire area of a computer's output - all of 1 screen and (presumably) all of the 2nd monitor if you have a dual monitor setup.

my app currently doesn't support using multiple screens at the same time. It'll only use the screen that is selected in the main window.

what i'd like is a flexible box that you can resize to control certain parts of (or all of) a selected screen. (kind of like some screencapture applications, where you simply resize the box and capture just that space underneath).

I understand what you mean, I'll consider including this in a future release.
I can't make any promises or give you a timeline though, since I'm working on this in my spare time.

examples of use:
- dual monitor setups where 1 screen is different resolution than the other (1 screen, 1 projector)

Do you mean selecting a region that spans across multiple screens?

for the purpose of physically drawing automation curves (such as the one below) directly onto an LCD screen, this function would be incredibly and legendarily groundbreaking.

What are these "automation curves"?

Hi monsho,

you can do that by using the runtime option org.uweschmidt.wiimote.whiteboard.wiimoteAddresses to let the app connect to specific Wiimotes  only. Or you can limit the app to only connect to a single Wiimote, using the org.uweschmidt.wiimote.whiteboard.wiimotes option. Please read this for more information:

Hi Chris,

I have to do a senior research project this semester and am interested in doing one involving a wiimote.  I was wondering if anyone could give me a nudge in the right direction.  I'm not looking for spoon fed answers or a project spelled out for me.  Just some general areas I could do research in and places I could find info on programming with a wiiremote.  Thanks!!!

you might think about using the Wiimote, Wii MotionPlus, or the Wii Balance Board as controllers and/or sensors for applications that currently cost a lot of money due to special hardware requirements.
As far as info on programming goes, you're welcome to check out the source of my Wiimote Logger and Wiimote Whiteboard apps →


your problem could be caused by the app looking for a second Wiimote in the background, and errors may occur when it finds other devices like cellphones.
For now, you can turn that off by setting the runtime option "org.uweschmidt.wiimote.whiteboard.wiimotes" to "1"; please see the wiki at

Hi Brendan,

did you follow the these instructions?
I have neither tried this with Linux Mint nor Puppy Linux, but it might work with some tweaking.
Try starting the app with java -Dbluecove.debug=true -jar WiimoteWhiteboard.jar to see additional debug messages.

Sorry for the late reply,

2) There is too much work to do when most people just really want to be able to install 1-2 things and connect to it automatically.   

It was too much, and honestly, I cannot demonstrate this product all the while saying that it is easy to do, which it is not if it will take this amount of work to by-pass the current driver just to make Whiteboard work.

I'm disappointed that I won't be able to use Whiteboard, nor will I be able to demonstrate it.  I will have to unfortunately use Smoothboard (it is also great but the cost of it is too expensive).

Here's my reply.

Btw, my app is free of charge and developed in my spare time.
You have to invest some time to get it up and running the way you want. The alternative is to buy some other whiteboard system or pay someone else to do it...

Hi, you could try running my WiimoteLogger app, which saves data in the common CSV format that can easily be imported into Excel, OpenOffice, etc.


Programmers Den / Re: Help: Smoothing for 4 separate IR points
« on: March 22, 2010, 11:33:48 AM »

How would you handle smoothing? And how would the algorithm for smoothing look?

smoothing isn't really rocket science:

Boon Jin is referring to
If you want to get more fancy, e.g.:

Btw, have you considered using the TUIO data from my app (link in my signature) as input to your game? This would save you the trouble of interacting with the Wiimote at all... just a suggestion.



each Wiimote tracks the 4 brightest IR lights that it "sees", as far as I know.
Hence, you can track more points if the Wiimotes are not looking at the same set of 8 points.
Depending on your application, you could also try to use (asynchronously) flickering IR lights, so that only a subset of lights is visible at any given time, giving the Wiimotes the chance to eventually see all of them.
