When this happens, I'm thinking I'll have to use a rear projection set-up for my board.  If four of my first graders are using the board at the same time, they will cast so much shadow on the wiiboard that nobody will be able to see anything.  This guy, who I think is a first grade teacher in Iowa has a great set-up.  He stated that he built the stand and bought the rear projection screen from Rosebrand.

hello,
I found a application not built exactly for ir pens but we could work with it on wiimote project as a group project

Has anyone found any programs that can do the whole multi-touch thing. I would love to make a table for my classroom that would allow several kids to play at once. I came across this website the other day if anyone knows what to do with them:
http://www.softmt.com/
It has quite a few apps to download but I can't figure out how to work them.

Have y'all seen this? - http://code.google.com/p/wiimotetuio/

It's supposed to be a Wiimote Whiteboard -> TUIO data converter. Haven't tested it very thoroughly, but it did seem to work with a TouchEarth plugin for NASA's WorldWInd.

But, most of the multi-touch programs are Flash. I'm not entirely sure of this, but I believe there are programs that  enable Flash to receive OSC/TUIO (Flosc - http://code.google.com/p/flosc/)

Haven't gotten any Flash apps to work yet. But, I only tested for about an hour or two.
Good luck

P.S. - Did manage to get some Flash apps to recognize the IR lights as TUIO!

we can use tuio based wiimote surface to bridge to multitouch vista project see http://www.codeplex.com/MultiTouchVista
 and daniel's awesome HID driver to get multitouch in windows also have multiple mice
great right?

Eric, I would be interested to see what you come up with on the rear projection idea, I have had some success with greaseproof paper on the back of a Perspex sliding door of a fume hood in the science lab. Something I learnt from a post here...

I would love to explore the idea of some cheap voting system, the first thought that pops to mind is some cheap old PDAs on a wireless router, just need to find some old PDAs somewhere....   Junk yard here I come...

Cheers
DJM

Hi,

has somebody successfully configured MPX (the multitouch X server) in Linux??  It could solve the multitouch issue for linux platforms, but I don't know how to install.

If so, could you please post some information??

Thank you in advance

Chema

I have had success using MultiTouchVista, Windows7 and WiimoteTUIO v0.4. However, the main issue here is with regards to the smoothness of movements. Both programs recomended by people on this site have those functions built in. So if one were to either add TUIO output to BoonJinns program, or to modify WiimoteTUIO so that it outputted "smoothed" TUIO data, then we would have an (almost) true smooth hardware based multi-IR tracking system.

Hi,

Nice to hear that you have reported success in Windows 7 and WiimoteTUIO.

I am considering to add multitouch support to Smoothbboard but have not seen many applications that will benefit on this feature yet. Maybe Windows 7 will change this perception. :)

Actually the smoothing codes that I have implemented in Smoothboard is quite simple and short.

A simple modification on WiimoteTUIO should do the trick.
The codes can be extracted from Brian Peek's book (Wiimote Whiteboard chapter, co-authored by Johnny Lee and myself)

Hello, I am a Smoothboard user and used it in powerpoint presentations with the pptPlex plugin from office labs.
It works great but it would be even better with the multitouch version!

I tried to use TUIO + Multitouch vista on win 7 but the result was not good: too much lag in the whole chain, I couldn't have natural motions (with my laptop anyway...).

Boonjin, as soon as you add multitouch to Smoothboard I will use it with the touch version of pptPlex!

Thx
Thomas

There are some pretty cool multi-point programs here: http://grouplab.cpsc.ucalgary.ca/cookbook/index.php/Toolkits/SDGToolkit
along with tutorials on how to write your own.

I'm not sure if it's possible (I'm new to the Wiimote Whiteboard thing and have a steep learning curve), but is there a way to use programs like this, using each IR pen as a separate mouse? I tried it, but the IR pens don't seem to be recognized as mice at all. I'm hoping there's a simple fix that I'm not seeing (maybe something to do with TUIO?).

Does anyone have any experience with programs like these?

Just posted this in another forum group and I want to verify my answer and see where multitouch is at.

The problem, as I understand it, is how a cursor maintains focus on a particular user as all the IR light sources are toggled on and off - unless the screen is segmented.

Hey guys,

Sorry to bump the topic but I do have something of value to add! :-)

I have written an app which smooths and classifies the cursor input with multiple pens and can generate TUIO and Windows 7 events by directly interfacing with Daniel's aforementioned driver.  Essentially meaning it's done. :-)

I just made a thread here where you can read more: http://www.wiimoteproject.com/wiimote-whiteboard/wiimote-with-windows-7-and-tuio-multi-touch-support/msg11968/?topicseen#msg11968

Here is a more detailed description:
Quote
WiiTUIO is an application which stabilises the IR sources captured by a Wii Remote (Wiimote) and presents them as TUIO and Windows 7 Touch messages.

This project aims to improve the stability of the IR sources captured by the Wiimote using some thresholds and spatio-temporal classification. The application generates Windows 7 Touch messages and TUIO events using these stabilised contacts.

Each raw IR source captured by the Wiimote is either assigned to the best existing tracked source or generates a new tracker. This means that TUIO events can be generated from stable data without the jitter (namely, false-positives generated between two IR sources and the unordered source buffer) that occurs when trying to use the Wiimote to capture true multi-touch IR.

And here is a demo video (sorry for the muffled sound - it was taken on my mobile):

I'm having trouble loading this.... I get stuck at the stage where I'm supposed to type Install driver.cmd - running as administrator  - I get error messages

sorted it... you have to put the "" marks in so it should be "install driver.cmd"
it wasn't obvious...
