Wiimote Java Whiteboard / Re: Multitouch & Java Whiteboard
« on: November 16, 2009, 06:15:26 AM »
Hi Chema,

Thanks Uwe, it worked with the local IP.

BTW, as you say in your web it works with flosc 1.3 but not with flosc 2.0.
It doesn't work neither with Nasa Worldwind touch plugin.

Any idea about this issue?

I actually don't do any multi-touch stuff myself, sorry.

Anybody knows any program (port sniffer) to show the messages sended to the port so I can compare those used by the TUIO simulator and Java Whiteboard? Maybe I can find the problem with it.

Have you tried Wireshark?

Yes of course, its 127.0.0.1:3333, i also tried with localhost:3333
I write wrong the address in the post.

Have you tried using the (local) IP address of your network card?

Hi chema,

I configured Java Whiteboard to send the messages to the same address that CCV (127.0.0.0:3333) but it didn't worked. do i need another program as gateway or something??

you mean the address 127.0.0.1:3333, right? Otherwise, that could be the problem.

Sorry for the late reply,
Uwe

Hi,

have you tried using any of the TUIO simulators instead of the Java Whiteboard? By doing this, you can check whether it's a problem of the Whiteboard software or the Flash multitouch app you want to use.

Thank you very much, I will get a new dongle that is widcomm compatible.

Make sure you don't buy something that won't work either. Please see this post.
I unfortunately can't really help you with that since it's been a while that I dealt with Bluetooth on Windows...

Hi,

I also understand that it could be my bluetooth stack. If this is the problem it would be a easy fix, right?

I am using BlueCove version 2.1.0 on bluesoleil

I'm afraid my app won't work with the BlueSoleil Stack. Please see http://www.uweschmidt.org/comment/166

Hi,

[...]i am getting this error -

on this line -
Code: [Select]
throw new IllegalArgumentException(JaiI18N.getString("Generic0"));
the compiler can not find "Jail18N"

just delete (or comment out) this particular line that gives the error.

Uwe & Pro2785
The latest Widcomm is just MS Bluetooth rebadged it will not work with Jave you need the Widcomm v4 (not sure if v5 will work but def not with .Net apps).

I've nothing to add. It's been a while since I dealt with Bluetooth on Windows...

Hi KE7JLM,

How do you use the Ant build-script?

you first need to install Ant on your machine: http://en.wikibooks.org/wiki/Apache_Ant/Getting_Started/Installation
Then just run the command "ant" at the command line in the folder where you've extracted my source code to.

Hi prometheus2785,

Not Supported on winsock

what does this mean?

[...]

I thought I had installed bluecove, but I may be wrong.

it means that my application doesn't work with the built-in "winsock" Bluetooth stack by Microsoft. It looks like you need WIDCOMM in order for it to work...

Btw, there's no need to install BlueCove, it comes bundled with my application.

Sorry for the late reply,

Well, if you're already calibrating each Wiimote separately (with it's own set of 4 points on each half of the screen), then it should just be a matter of converting the units into a space for a single screen. For example (this is what I would try):
...

It's actually not that hard. Each Wiimote basically has its own "Warper" that maps from its coordinates to screen coordinates.
So whichever Wiimote sees the IR point, that "Warper" is used. If both Wiimotes see the point, I just arbitrarily use one of them. I could also average the projected coordinates, but so far I didn't bother...

Well, my screen is too large and I found that one wiimote ir camera cannot cover the whole region, I just wanted to know if it is possible to use two or more wiimotes, one cover parts of the screen, the other is responsible for the rest area. For example, when calibration,  the screen's top-left and lower-left corners are captured by the wiimote A, while the top-right and  lower-right corners are captured by the wiimote B.
- You might do something like an 8-point calibration, 4 points for each half of the screen and it's associated Wiimote (the Wiimotes should ideally be pointed in such a way that there is a little overlap in the middle).
- Then project both quads like they were individual whiteboards.

My software is already doing this, so please have a look at the source code if you like: http://www.uweschmidt.org/wiimote-whiteboard
Read about the calibration procedure here (step 4): http://wiki.uweschmidt.org/WiimoteWhiteboard/HowToUse
