Uwe on Wiimote Whiteboard in reply to Matt Davis
Hi Matt,
are you using this on Mac, Windows, or Linux?
Some of stuff we need to have fixed. 1. Faster connecting between the wiimote and the program
The connection sometimes doesn’t work for me the first time. A simple retry does this trick for me. What do you mean by “faster”?
2. Does not lose connection randomly
Never experienced this problem on the Mac during development.
3. Get rid of lag when using one wiimote on Mac with a bluetooth doogle.
Never tried using a Bluetooth dongle, although can’t think of a reason why it should be slower.
4. Maybe add a save calibration setting. redoing the calibration sucks.
My app saves the calibration settings. So there should be no need to re-calibrate if the Wiimote and the display haven’t been moved.

Fernando Barbosa on Wiimote Whiteboard
Hi Thanks for your program. It seems it works fine in my Mac but there are some things I want to improve:
1 - The visualization area keeps very reduced - it is always around 5%. I moved the wiimote around but I cannot improve it!! (got a value of 40% in the first atempts, but could not get it again).
2 - The camera monitoriing functioned the first time I used the wiimotewhiteboard..but never again. What is wrong?
Thank you again
Fernando

“are you using this on Mac, Windows, or Linux?” I am using iMac on the Mac OS
“What do you mean by “faster”?” Some of the time it takes forever for the program to find the wiimote or sometimes the wiimote will connect to the computers bluetooth service and not the program.
The connection of the wiimote to the Mac will randomly drop. I believe this happens when their is more bluetooth devices in the room because when their is no one else with cellphones with bluetooth services it stays connected for hours but when classroom full of students the connection drops very quick! So my suggestion is to add a setting to stop and resume looking for wiimotes, so other bluetooth devices don’t interfere.
The reason why I am using bluetooth doogle is because my iMac does not have a builtin bluetooth. Other iMac’s that do have built in bluetooth run the program smooth. This is the bluetooth doogle am using. It works fine on mac but causing lag http://www.amazon.com/2-4GHz-Bluetooth-Dongle-Adapter-Windows/dp/B0019SI266/ref=sr_1_3?ie=UTF8&s=electronics&qid=1277662433&sr=8-3-spell
Thank you for telling about the save calibration, we have always been taking it down after using it.
Hope we can resolve this problem that I am having and I wish you my Best regards -Matt Davis

Hi zalis,
i was wondering how can i actually open this code in net-beans […] i was unable to even open it net beans because it was not locating library files.
I personally don’t use NetBeans, but I believe it can import the configuration from an Apache Ant build script, which is included in my source code download (build.xml). If you want to do it manually, you just need to add all the jar-files from the lib folder to the Java classpath.

Hi Fernando,
1 – The visualization area keeps very reduced – it is always around 5%. I moved the wiimote around but I cannot improve it!! (got a value of 40% in the first atempts, but could not get it again).
don’t worry about the tracking area as long as everything is working fine.
2 – The camera monitoriing functioned the first time I used the wiimotewhiteboard..but never again. What is wrong?
Does the application otherwise work normally? If so, that’s strange.

Hi Matt,
“are you using this on Mac, Windows, or Linux?” I am using iMac on the Mac OS
are you by any chance using an old iMac with a PowerPC processor? If so, that could explain some of your problems (read the Bluetooth section in the Wiki).
The connection of the wiimote to the Mac will randomly drop. I believe this happens when their is more bluetooth devices in the room […] So my suggestion is to add a setting to stop and resume looking for wiimotes, so other bluetooth devices don’t interfere.
This is certainly possible that other Bluetooth devices interfere. I’m unable to test this however while developing the software. In order to stop the app from looking for further Bluetooth devices, consider setting the runtime option org.uweschmidt.wiimote.whiteboard.wiimotes to “1”; see the Wiki for instructions.

Hi, I’m wondering if I can use a normal infrared receiver rather than the Wii Remote?

Hi Uwe, I like all the ir led possibilities! Yesterday I have installed your software on my laptop Mac (OS10.5.8); I’ve followed the instructions on preferences etc. And I have come till the callibration of the 4 points. with my ir ledpen. I tried both with the wiiremote on a beamer and on my laptop screen. both give the same result: After the four √ ‘s of the calibration, the irledpen can not be used as a mouse. and I cannot draw or so. The proces stucks. What do I forget? Hope you can help me out, thanks, Maatje (Netherlands)

Foxra on Wiimote Whiteboard
your solution to “force” it to start with widcomm didn’t work. i copied the command listed into the command propt, and it says “Bluetooth failed to initialize. there is probably a problem with your local bluetooth stack or API”… so uh, i downloaded and installed Widcomm but nothing really seems to have changed.. i know when i went to install it, it said to connect my bluetooth device. when i connected it, windows instantly started downloading windows drivers. but then when the install of widcomm finished the driver listed shows broadcom instead of iogear like it usually does lol. idk how to get this stupid thing to work…

chryjs on Wiimote Whiteboard
Hello, I finally succeed in install of wiimote whiteboard on windows XP (I had hard times because it refuses to recognize windows bluetooth stack but I replaced it with widcomm). Now I have a problem : how to correctly connect 2 wiimotes (improve the reception because of lefthanded / righthanded users) ? Whatever I do the software complains about one of the wiimote “out of the screen limits” and need recalibration. When I “look” at the wii camera screen the plot 1 & 2 are correctly located and very near… Thanks for your help…

Diptesh on Wiimote Whiteboard
When I am starting the application on Windows, as soon as I start the application I am getting two IR dots and the calibration is getting done even though I haven’t used any IR source. I have used WIDCOMM Bluetooth stack. My wiimote is getting detected properly. But I am not able to figure out how two IR dots are getting detected without using any IR pen. No other IR source is there near my PC. Please let me know if where the problem can be ? Thanks & Regards, Diptesh
-
Boon Jin on Wiimote Whiteboard in reply to Diptesh
Hi Diptesh,
The stray IR source may come from sunlight, lamps, laptop, mobile devices.
If you cover the Wiimote’s IR camera and still there is 2 dots registered, you may have a faulty Wiimote. Have you tried using Smoothboard to see whether the same issue arises?
Regards, Boon Jin
-
Diptesh on Wiimote Whiteboard
Thanks for your quick response. And yes I have tried using the same wiimote with Smoothboard and it is working fine. Also I have tried using WiimoteLib with test application and it is also working fine. Only when I am using WiimoteWhiteboard, this issue is arising. Can there be some issue with WiiRemoteJ library ? Thanks.

Toni on Wiimote Whiteboard
I’m using Debian Lenny in a Acer Travelmate 803LMI notebook. I tried to install and run wiimoteWhiteboard.jar after installing and adding http://bluecove.googlecode.com/files/bluecove-gpl-2.1.0.jar as described in post http://www.uweschmidt.org/comment/166 but I can’t get to run it as expected.
The log displayed from the console was:
Acer:/home/tonisoto/whiteboard/WiimoteWhiteboard# java -jar WiimoteWhiteboard.jar JarClassLoader: Warning: Unable to load native library: java.lang.NullPointerException JarClassLoader: Warning: Unable to load native library: java.lang.NullPointerException JarClassLoader: Warning: Unable to load native library: java.lang.NullPointerException JarClassLoader: Warning: Unable to load native library: java.lang.NullPointerException Null peer?!

… and it hangs!
.. the strange thing about that is that I have also installed the package gtkwhiteboard and it runs as expected: I mean it connects to wiimote and it let me calibrate the screen and using it.
Any idea about my issue…?
Thanks in advance.

EMoore on Wiimote Whiteboard
Hi! I’m so excited about using your project but….Teacher in need-
When I am trying to get the bluetooth device to pick up the Wii remote, the device recognizes the remote and I begin the installation process. The problem occurs when I get to the message window where a pin or code is required for my Wii controller. The directions that I have found state that you should not enter a code and click skip or no code, but I do not have the option. I cannot click the next button and proceed with the installation unless there is an accurate code. We have tried guessing, that does not work- unfortunately!
Your help will be much appreciated! EMoore

Hi,
If you are connecting manually using the Widcomm Bluetooth stack and it asks for the pass code, you may want to try to press Alt+S on the keyboard.

Hi,
Thank you for making this available. I’ve downloaded it and am just about to try it out in the coming weeks. Will buy a pico projector, make an IR pen and… is there any way to make a whiteboard using the MacBook’s infrared detector, or isight camera (with IR filter)???
In thanks…

DubPrecalc on Wiimote Whiteboard
I’m using a macbook. I cannot connect to my wiimote consistently. I’d say I’m getting a connection about 1 out of ever 25 times. I know it’s not a hardware issue. (at least I’m pretty sure) I am consistently getting errors from my WiimoteWhiteboard. Please Help!
Thanks.

my app can only be used with a Wii Remote.

Uwe on Wiimote Whiteboard in reply to Patrick
Patrick,
Is there a way to support multitouch in Mac os.?
do you mean to trigger Mac multitouch commands (e.g. rotate and zoom) like they’re possible with the trackpad? That’s not possible with my app.
-
Uwe on Wiimote Whiteboard in reply to Maatje van Eck
Hi Maatje,
After the four √ ’s of the calibration, the irledpen can not be used as a mouse. and I cannot draw or so. The proces stucks.
maybe there are additional sources of infrared light like sunlight or light bulbs (see “Visible IR dots”), that could explain why it doesn’t work. Also, “Mouse Control” has to be enabled with option “Move & Click” selected.

Hi Pietro,

my app doesn’t work with Winsock, please see this previous post.

Hi otilio,
I haven’t tried my app with Windows 7 at all, it might work when you’re using the Widcomm Bluetooth stack.

Hi chryjs,
Whatever I do the software complains about one of the wiimote “out of the screen limits” and need recalibration. When I “look” at the wii camera screen the plot 1 & 2 are correctly located and very near…
maybe you’re blocking the view for one of the two Wiimotes during calibration? From How to use:
During calibration you’ll either see a checkmark or warning triangle for each connected Wiimote at all previous calibration points. They give you feedback whether a Wiimote saw the point or not. In case not all connected Wiimotes saw all 4 points, the calibration will continue until each Wiimote sees at least one fourth of the screen. All Wiimotes together must also “cover” the entire screen.
-
Hi Diptesh,
Only when I am using WiimoteWhiteboard, this issue is arising. Can there be some issue with WiiRemoteJ library ?
I don’t think there is an issue with WiiRemoteJ. I’d go with Boon Jin’s assumption of stray IR light. Does Smoothboard work under the exact circumstances when my app doesn’t?
-
Hi Toni,
maybe you installed a “headless” variant of Java that doesn’t come with the GUI libraries? Please see this previous post.
-
Hi,
[…] is there any way to make a whiteboard using the MacBook’s infrared detector, or isight camera (with IR filter)???
it is possible to build a Whiteboard using a Webcam with an infrared filter (instead of using a Wiimote), but that is not supported by my application.

Uwe on Wiimote Whiteboard in reply to DubPrecalc
Hi DubPrecalc,
I’m using a macbook. I cannot connect to my wiimote consistently. I’d say I’m getting a connection about 1 out of ever 25 times.
are there a lot of other Bluetooth devices around when you try to make the connection? If so, that could be the reason why it is so unreliable. You could try using the “org.uweschmidt.wiimote.whiteboard.wiimoteAddresses” runtime option to restrict connections only to your Wiimote, please read this for more information.
-
chryjs on Wiimote Whiteboard in reply to Uwe
Uwe : I’ll make a new test in the next days and I’ll make a video :)… But I use the exact same operations for both wiimote, symetrically.
In fact it’s ok for 1 Wii , but the second one have ALL the points “out”… As if the calibration was wrong. Looking at what this wiimote “see”, is however ok…

Ben on Wiimote Whiteboard
Hi Uwe,
only one problem, i’m using a macbook, and one i’m calibrating, only one IR dot appears and calibrates, isn’t their suppose to be four of them?
-
Uwe on Wiimote Whiteboard in reply to Ben
Hi Ben,
what exactly happens when you try to calibrate? Does the calibration screen disappear after you do the first calibration point?
Maybe there are other sources of IR light interfering, like sunlight or light bulbs. Have you checked the “IR Camera Monitor”?
-
Ben on Wiimote Whiteboard
Hi Uwe,
i honestly don’t know what happened, but yesterday it wasn’t working, but today everything’s fine. Thank you for your quick response.

HowGood on Wiimote Whiteboard
Hi Uwe,
Do you know of an application that does use the built-in iSight? My thought has been to try a buffed plexiglass screen between me & the laptop, which is projected on and seen by the camera. Then use as a touchscreen.
