Descalzo on Wiimote Whiteboard
PowerPC Bluetooth
OK, my story so far: I have a MBP with built-in BT, and a TiBook without BT, but a dongle. I got it to work with the TiBook with the Kensington dongle finally, by repetition. I kept deleting it from devices and re-running the jar file. Eventually it took. Boy, that was a pain.
Sadly, however, I still don’t have any more success than I did before. The pen picks up a little better than it did on the MBP, but it’s still unusable. This is odd, because it works on the MBP under Boot Camp/Windows XP with Johnny Lee’s software.
So the only hardware change is still the BT adapter. Windows uses the Logitech one, while OSX can’t. I’ll have to test the Kensington dongle with XP, but I’d really like to pair the WiiMote to the Apple Built-in BT under XP. I haven’t been able to do that yet.
If anyone else has some more ideas on what I could try I’d love to hear it.

It works with the Mac Intel and 2 flashlights. I have a special kind with led light that I place under the Mac, then I use the flashlight instead of the pen. It’s hard to callibrate though, so I will have to get or make an IR pen for more accuracy.

It works on XP too
Hi,
Nice job !
I work as a technology teacher in France (12-16 years old childs). As my school is quite poor ;-), I have to find different ways not to waste the money, and this software is a good one ! Several things are locked by our administrator, I hope that java will allow me to run the whiteboard. I was using the original software, but I think your job is full of promises (I’m waiting for the right click implement ;-)) I’m running on XP SP2 with a F8t012 belkin dongle on a toshiba laptop (home) and I’ll try with xp/2K at school.
One question : Java 6 is installed one my computer, but I had to add “Java Advanced Imaging” in the jar archive to make it work. Is it normal ?
Thanks, see you soon.

Windows & JAI
Hi Julien, it’s nice to hear that someone is actually using it on Windows :) Which Bluetooth stack did you use? I never got it running on my PCs but I borrowed another Bluetooth dongle from a friend to do some further testing.
One question : Java 6 is installed one my computer, but I had to add “Java Advanced Imaging” in the jar archive to make it work. Is it normal ?
I’m using Java Advanced Imaging (JAI) to do the transformation from the position of the IR light the Wiimote sees to the position of the mouse cursor on the screen. I thought JAI was bundled with all JREs. Thanks for pointing out that this is not the case!

Update
The new version of the software will be available as Mac application bundle and “generic version” that will run on all platforms. I’m currently trying to figure out which license I can use. Don’t worry, the program will stay free to use. I also want to include some help that covers the basics.

OSX Woes
Well, here’s the new story. I got an IOGear BT stick and plugged it in. It works better than the Kensington or the built-in BT from the MBP.
But still not good enough. It picks up smooth and steady when I aim the pen right back at the wiimote, but when I use it as a pen to draw on the board/monitor, it picks up nothing, or very very little. It’s very jittery (if visible at all!) when I aim it at the screen. In fact, I ran a test with it and only got it to pick up a reliable signal from the IR pen when I had the wiimote less than 4 feet from the screen.
Then I BootCamped into Windows XP and tried it there. I used the IOGear stick and Johnny Lee’s software and everything was wonderful. Then I tried it with your software and it was horrible. Just like before. I tried it (in Windows) from only 6 feet away and it would not pick up any IR dots. When I used Johnny’s program it was fine.
What could be causing this? What else could I try?

More info
In case anyone is curious, I am using an IR pen made from a Radio Shack IR LED and one AAA battery. I don’t know if this helps. Any ideas on how to make a brighter pen?

Re: OSX Woes
Hi Descalzo,
I’m honestly clueless why you’re having this problem since I assume you’re using the exact same setup (same monitor, IR pen, etc.) to run both tests. I also can’t imagine that it is a Bluetooth issue.
It picks up smooth and steady when I aim the pen right back at the wiimote, but when I use it as a pen to draw on the board/monitor, it picks up nothing, or very very little. It’s very jittery (if visible at all!) when I aim it at the screen.
Same here. But my IR LED is too weak and I actually haven’t used Johnny’s program on Windows to do a comparison. I’ll do some more tests…
Btw: The new version is out!

Error sending data
Hi

Heya, I tried it briefly on
Heya,
I tried it briefly on a Macbook, with an Apple remote. That worked, and I could sortof ‘click’ (cover was still on the Apple remote, and of course it flashes rather than lights up), but some time of random clicking, I got the “Error sending data” as well.
Other than that, it did work, and that’s great! Going to consider putting together a pointing device (pens suck as a form factor, I’m gonna see if I can find what I want :))

No, the program didn’t quit. I can only click ‘ok’ on the error-message, but then it reappears. Forced stop works and also pushing the home-button on the wiimote. If I do that and I instantly restart your program it works. very strange indeed.

Error Messages
Hi, I also got the Error sending data! once today. I looked around the WiiRemoteJ forum and found this:
Right now errors message are simply forwarded to the GUI. The reason for that is they would otherwise be unnoticed and the user has no idea what’s going on. I cannot really do anything against these errors since they come from libraries that I just use. I can only change my program to behave more “nicely” when they occur. Instead of displaying a blocking error message there could be an “Error Log Window” or something like that. In case of severe errors the program could gracefully reset itself to initial state or do a reconnect (I have to investigate into that). Other suggestions?
More info: the previous release did not have this problem. Also, when run with BlueCove debug enabled, nothing appears abnormal.
I guess that’s because all errors were simply ignored :)
This happens consistently 60 seconds after the wiimote connects. Does the code do a status check on the wiimote then?
Yes, I do a status check every minute to update the battery level. Does the program work normally until the error occurs?

Wii Remote and Mac Connectivity issue
I can’t get my MBP to connect to the Wii remote. Is there a process i must follow? Do I need more than just the remote? My bluetooth was on, discoverable. Im running 10.5.1 I have not upgraded to 10.5.2 yet. Could that be the issue? It baffles me as to why i can’t view the remote. Does it show up as a ‘wii remote’?
In the preferences when I did a search, I had selected ‘All Devices’, as there wasn’t an option for remotes…but i only picked up cell phones.
Any suggestions would be helpful!!!

Hi George,
I can’t get my MBP to connect to the Wii remote. Is there a process i must follow?
everything is described in the help files accessible via Help ? WiimoteWhiteboard Help in the current (Mac) version of the program. Post again if you still have trouble connecting.

It works on windows, but I can't use it...
Hi,
I was happy to see that this software works on my laptop screen, but I can’t use it on a real white board… When the wiiwote is 3 meters far from the whiteboard, The IR dot is not “seen” by the wiimote… It works fine with johnny’s soft (up to 6 meters), but when I use your soft (exactly with the same hardware configuration), I can only use it up to 1 meter… My IR pen is made of an IR led running at 3V, 130 mA (Not the problem, because it works whith johnny’s soft), no flashes are used…
I don’t know where it comes from…

eratic pointer
Thanks for the tips Uwe. I was able to connect the two, however I have a very hard time calibrating anything with my ir pens. One of them is IR LED with 940nm, but I need to have the wii remote almost directly over the pen, otherwise nothing happens. If I use the apple remote, it works but only a bit. I can calibrate, but I find it’s choppy when moving around the screen.
Could it be that my IR LEDS are not powerful enough?

Strange
Hi Julien,
It works fine with johnny’s soft (up to 6 meters), but when I use your soft (exactly with the same hardware configuration), I can only use it up to 1 meter…
Descalzo apprently has the exact same issue. I guess one has to find out the differences between the different Wii Remote libraries, used in my and Johnny’s program, to solve the mystery. That could be difficult…
I actually got my program working today on WinXP SP2 with a recent WIDCOMM stack. Now I can test the difference between my and Johnny’s program as well.
Hi George?, I guess you take a look at the wiimoteproject.com forums, especially the support forum for the Wiimote Whiteboard. I’m sure you’ll find valuable information there.

FINALLY: IT WORKS
Finally, I got this thing to work. My IR LED were the problem. I took one out of an old remote and switched it and voila…worked like a charm. I find opening folders to be a bit challenging but other than that it works.
Only wish I could ‘draw’ without being in a drawing program…like being able to make circles or write on the screen when a web page pops up. OH well…beggers can’t be choosers though.

Drawing & Donations
I’m glad you got it working, George.
I find opening folders to be a bit challenging but other than that it works.
I guess that’s because you’re always jittering a little bit with your hand and the sensor values are also not always stable. It’s less of a problem if you use it with a big screen or projector though.
Only wish I could ‘draw’ without being in a drawing program…like being able to make circles or write on the screen when a web page pops up.
Yeah, that could be cool. But I don’t think this functionality should be added to the program. In my opinion, a program should only do one ‘thing’ but do this really well.
The good thing is that you can just use existing programs which make use of the standard mouse. I found Desktastic with a quick search. It apparently does all what you want, I haven’t tried it though.
Do you accept donation?
I actually put a PayPal donate link (“buy me a drink”) on this very page under Support when the new version came out. Donations are gladly accepted as a form of “Thank you”. I do however not accept donations as a form of payment for requested features. My motivation behind this software is not financial.
So decide for yourself if you want to make a donation :)

Wiiremote library
Dear Uwe,
It seems that you use the same library as wiiremote. I had the same (low range) problem when I used wiiremote : Dots where invisible if I was too far (> 1m), so it seems that the library is the key of the problem…

Error Message as well
BTW, I’m also getting the error message. It really only becomes a problem when I need to re-calibrate the screen, as the error message doesn’t allow for that, which means I must FORCE QUIT. Other than that little bug, it works okay.

Low Range Problem
Hi Julien,
I directly compared my to Johnny’s program today. I have the exact same issue of a low range with my program.
It seems that you use the same library as wiiremote … so it seems that the library is the key of the problem…
What library (“wiiremote”) are you talking about?. I use WiiremoteJ. I’ll take a look at the Wiimote library that Johnny uses in his C# program. Unfortunately I cannot compare it to WiiRemoteJ since it’s closed-source. I’ll talk to the developer of WiiRemoteJ…
BTW, I’m also getting the error message. It really only becomes a problem when I need to re-calibrate the screen, as the error message doesn’t allow for that, which means I must FORCE QUIT. Other than that little bug, it works okay.
Does that mean that software is working fine although the error message pops up? This bug will be fixed in the new version for sure. I started to implement some sort of Error Log that can be displayed on demand…

Wiiremote + Right click
Hi Uwe,
I was tryins to say that when I use the soft wiiremote (showing acceleration with graphs, IR dots, Wiimote keys, etc…), I have a low range problem. I have the same problem using your soft (that’s normal because it uses the same library). That’s nice if you can have a look, I hope that wiiremote developer can help.
Just a suggestion for right click : I think that it would be better (if possible) if the user can right click once the second is over. Actually, right click happens when you release the button, but I prefer to wait 2 or 3 seconds to be sure that it works. I mean that the right click should happen directly at the end of the second without releasing the button…
Thanks.

IR Sensitivity & Right Click
Hi Julien,
Wiibrew says that there are three known to work IR camera sensitivity settings. Johnny Lee’s program uses this Wiimote library which uses the maximum sensitivity settings. I assume that WiiRemoteJ might use another one. I actually wrote the developer of WiiRemoteJ an email about it a couple of minutes ago.
Just a suggestion for right click : I think that it would be better (if possible) if the user can right click once the second is over. Actually, right click happens when you release the button, but I prefer to wait 2 or 3 seconds to be sure that it works. I mean that the right click should happen directly at the end of the second without releasing the button…
The right mouse button is pressed after one second and released again if the IR pen is turned off. A click is the combination of press and release. So you’d prefer that a right click is executed immediately after the 1 second delay? It’s of course possible but raises one question: After the right click is executed, both mouse buttons are released, but the IR pen might be still on. How are you handling this case? Do you simply ignore all IR data till the pen is turned off and on again? Just proceeding normally wouldn’t be good since each right click would automatically be followed by a left button press. Do you understand what I mean?
Edit: You can change the default delay from 1 second to another value in case you didn’t notice. Just have a look at the preferences (either standard preferences on a Mac or Edit » Preferences on Windows)

Sensitivity + Right click
Hi Uwe
I was wondering about sensitivity… It would be nice if wiiremote allows to change this setting. Let us know ;-)
About right click why not try this :
ACTION–––––––––––––––––––—MOUSE STATE
IR on (moving)––––––––––––––––-Left click pressed IR on (not moving during 1 second)––––––-Right click pressed and released IR on (moving to select list item)–––––––—Both mouse buttons released IR off (above item you want to select)–––––-Left click pressed and released
In case you want the box to disapear, you only have to release IR pen button outside the item box. Once this is done (item selected or item box closed), the IR pen is off. Next time it will be on, it turns back to normal (left clic pressed).
Is it possible ?

New Version & Right Click
Hi Julien,
I was wondering about sensitivity… It would be nice if wiiremote allows to change this setting. Let us know ;-)
The new version is out! And it now uses the same sensitivity settings as Johnny’s Windows program. This was only possible due to the new release of WiiRemoteJ that came out today as well.
Is it possible ?
Your conception for right clicks is possible. Although I can’t find out what’s “under” the mouse cursor. Thus I don’t know if you’re trying to select a list item or do something else. But it’s doable in general. I’ll include this alternative right click implementation in the next version if time permits.

Error Sending data
Hello Uwe!
I am a computer specialist at Swallow Union Elementary school. I have become extremely interested in the wiimote whiteboard project, and am trying very hard to get this to work, but I continue to receive the ‘Error Sending Data’ message. What does it mean?
I have a bluetooth enabled MacBookPro running leopard. I downloaded the latest version of your software. I am pointing my wiimote at the probook monitor and hit the 1 and 2 buttons. Then I open up the software (I get the message that a new version is available everytime I open the Wii Whiteboard software, I say ‘no’), and then the software starts to look for the wiiremote, but ends in the ‘error sending data’ message. I have seen the error mentioned in other posts, but I did not see what to do to correct it.
Thanks for all you do! This project has amazing possibilities! There is no way we could afford to have this kind of functionalitiy in the classroom!

Re: Error Sending data & Updates
Hi Julie,
I continue to receive the ‘Error Sending Data’ message. What does it mean?
This error message is just forwared from a library that I use to connect to the Wiimote. I can’t tell you details beyond the obvious meaning.
I get the message that a new version is available everytime I open the Wii Whiteboard software, I say ‘no’
You can turn off this update check (in the preferences) if you want . But I higly recommend to always use the latest version of the software. The Error Sending Data issue might even be fixed in the current version. Just give it a try. The changes from one version to another are listed in the file CHANGELOG.txt that comes with the application.
I just got Leopard today and will thus be able to investigate into the Error Sending Data problem in combination with Leopard.

George on Wiimote Whiteboard
0.9.1 +++
The new version (just got it today by chance) works like a charm under leopard. The older version was a bit buggy. It was laggy and the error message would not go away. Under the new version the lag issue has been resolved it is a bit more accurate and the error message is gone away. I find the clicking is a bit more improved as well.
If anybody is an educator the software also works great in combination with smartboard notebook http://www.smarttech.com (its a free download)
Good Job on the upgrade.
P.S….will a higher output IR LED allow for the wiiremote to be placed further away from the board? I currently can only have it about 1.5 meters away. Anything further than that and it doesn’t work.

Uwe, I still only can see IR sources if I run the application via the command line using “java -jar …”. Running the application (on the mac) or double clicking the jar starts the program, but I can’t seem to detect the IR pen.

Sensitivity in the new version
I have tried the new version of your program (same hardware) and it still not compares to the original Johnny Lee on a Windows PC - It seems that the sensitivity setting is not enough to explain the difference - with your software I am back to the situation I had with less bright LEDs…jagged and broken lines when drawing and loosing windows when I move them. Using Johnny Lees app eliminates these problems totally. Other than that it is great software !!! - but I´m back to the long startup with Bluetooth connecting and imouse or Dmouse as free rightclick apps running too. I hope you solve the problem - in the mean time I am going to try out even brighter LEDs.

Thanks Uwe!
I finally figured out that although I am getting the message, I can still calibrate and successfully move forward with my experiment.
I got the whole thing to work last night and I am delighted. My next problem has nothing to do with your mac software, but I will pose it non-the-less in case you have any wisdom…After arduously moving my wii remote into a position that would calibrate on my white board, someone crashed into my tripod and now I cannot seem to find the correct height/angle to successfully calibrate. Can anyone articulate the best way to place a remote so that is it is appropriately angled for the whiteboard? I have watched Johnny Lee’s YouTube video, but it did not provide me with enough clues to determine what I am doing wrong.

Catching up
Hey guys!
P.S….will a higher output IR LED allow for the wiiremote to be placed further away from the board? I currently can only have it about 1.5 meters away. Anything further than that and it doesn’t work.
I suggest you have a look at the wiimoteproject.com forums, this post is especially good. The Wiimote can also apparently “see” some wavelengths better from further away. I’m be no means an expert on that. I just remember having read it somewhere.
I still only can see IR sources if I run the application via the command line using “java -jar …”. Running the application (on the mac) or double clicking the jar starts the program, but I can’t seem to detect the IR pen.
That’s odd. You mean the program starts up fine and successfully connects but no IR dots are detected? Did you do that like ten times in a row and always the same behavior?
… with your software I am back to the situation I had with less bright LEDs…jagged and broken lines when drawing and loosing windows when I move them. Using Johnny Lees app eliminates these problems totally.
Johnny’s app doesn’t really do any magic :) It could have something to do with his Wiimote library. It’s unlikely but I haven’t looked at the code. But here comes a general thing:
The communication with the Wii Remote is undocumented and not fully understood. All that is known has been found out by members of the community through reverse engineering.
Just consider this quote from Wiibrew:
After these steps, the Wii Remote will be in one of 3 states: IR camera on but not taking data, IR camera on and taking data and half sensitivity, IR camera on and taking data at full sensitivity. Which state you end up in appears to be pretty much random. Repeat the steps until you’re in the desired state.
So far I’m not aware of a way to query the IR camera’s state. That’s the reason why the program behaves differently sometimes. A future version of the software will have some “Reset Camera” function that re-initializes the IR camera. So please test several times before thinking it always works like on first try.
… Other than that it is great software !!! - but I´m back to the long startup with Bluetooth connecting …
The current version (0.9.1) always does a bluetooth device discovery and will connect to the first Wiimote that is found. I’m planning to include the option of connecting to a specific Wiimote by using its Bluetooth address. It is much quicker and has the advantage that nobody else can interfere with another Wiimote (like in a classroom) and beeing connected first.
… and imouse or Dmouse as free rightclick apps running too.
Why aren’t you using the built-in right click function? If it’s because it doesn’t work well in Windows, that will be fixed in the next version (already implemented, see Julien’s post).
I finally figured out that although I am getting the message, I can still calibrate and successfully move forward with my experiment.
Which message? And are you using the latest version?
Can anyone articulate the best way to place a remote so that is it is appropriately angled for the whiteboard?
I certainly can not, but try the wiimoteproject.com forums. One help with calibration are the Visible IR dots in the GUI. Point at each corner of the screen while moving the Wiimote around so that it can just see the light.

About sensitivity
Hello, I’m using a Windows XP PC and i have tried your last version of wiimote whiteboard (0.9.2) with a video projector. My wiimote is 1,5 m from the wall. When i compared Johnny Lee’s version to your’s, i noticed that the jar version was less sensitive : when drawing a curve, the line was slightly irregular.
Otherwise, with your soft the bluetooth recognition of wiimote is faster and more confortable, and the right-click option goes well. I appreciate too the large amount of informations that your soft gives and, of course, his platform-independence. So thank you for this very nice job, and i hope you will overcome this problem of sensitivity. Chris, from France.

Wiimote Placement / Calibration Issues
Can anyone articulate the best way to place a remote so that is it is appropriately angled for the whiteboard?
The reason lines are sometimes jaggy and drawing is difficult is because the area on the Wiimote IR-camera that covers the screen (or drawing-area) is not optimized correctly. Also even the slightest movement of the Wiimote will cause an effect which magnitude is a function of the distance between the Wiimote and the drawing-surface (the larger the distance the greater an effect a vibration will cause).
The optimum position would of course be through a see-through display where the camera would be perpendicular to the surface that it’s pointed at. This however is rarely possible and depends on the available equipment.
In order to optimize the position of the camera relative to the drawing-surface (your monitor for instance) it’s helpful to get a view of the actual pixels that the IR-camera sees. DarwiinRemote utility contains this tool (although it might be a bit difficult to find at first).
A tripod is suggested for the final placement of the Wiimote, make sure that any movement cause minimal disturbance/vibration to the Wiimote.
The optimization-process could be done for instance like so: 1. Connect to your Wiimote with DarwiinRemote 2. Activate only the IR-sensor 3. Show the IR-realtime data window from the “Window”-menu. 4. By moving your IR-pen along the edges of your monitor make sure that the IR-camera covers as big an are as possible. Move the position of your Wiimote in order to make this area as big as possible, it might require you to place yourself as much to either side of you monitor as possible. 5. After you’ve found the optimized position using DarwiinRemote it’s time to start using Uwe’s excellent “Wiimote Whiteboard”.
You can find DarwiinRemote (current version is 0.6) at http://sourceforge.net/projects/darwiin-remote/
Uwe, thanks for your excellent effort in bringing this to us OS X users as well!
If I may place a few future suggestments: 1. A window such as described above which would show exactly what the IR-camera sees (this would help the placement effort) 2. A mouse-movement smoothing option, essentially this would interpolate between the actual locations and not move to any given mouse-location directly. This would help to create more flow in Illustration applications.
Thanks, Carlington

Sensitivity + Right click
Hi Uwe,
Nice job for the right click, It works exactly as I want !
I still have a sensitivity problem compared to johnny’s soft (same hardware configuration and position)… Probably because of the library…
I hope next versions will fix the problem ;-)
Thanks a lot !

Wiimote LOG file
I have been having a particular issue. There are times, when I turn on the wiimote and instead of detection, I have the wiimotewhiteboard LOG file appear….sometimes I can restart and it goes away, other times I have to trash the program and re-instal. It’ll work once and then bang…the next time I load it up the log file reappears. Is anyone else having this problem? I’m running the latest version and I think it is a new phenomena with the release of 0.9.2.
Any info would be helpful.
Is the log file stored anywhere? If so, where and how do I delete it?
OSX 10.5.2

0.9.1
Is there a way i can download version 0.9.1 ? I find 0.9.2 requires the wiimote being less than a metre away from the screen. Meaning it will only work if i use my laptop as the screen. With a projector, I can’t get this to work effectively. I’m not sure what happened with 0.9.2, but I prefer 0.9.1 I deleted it after I installed 9.2. I find the latest version buggy… its skips a lot, moving windows around is difficult…if i drag an icon it will move for a bit and then stop following the cursor. When I draw, instead of getting lines I get dots.
