I am going to present a few projects on my blog in which I collaborated in one or the other way. The project UNFOCUS – FOCUS is a multi-touch and TUI project that makes use of our fiducialtuioas3 classes.
It has been a while since I gave a presentation about Natural User Interfaces at the webandwine event by the company mediaman on 7 May 2009. However, I found those two quite nice pictures of my presentation on the blog of Frank Hamm that I wanted to show here:
Important: I discontinued the work for fiducialtuioas3. If you are starting a new project, consider using our new AS3 Tuio library Tuio AS3. As you most certainly came here because you want to use fiducials in AS3 find the according Tuio AS3 fiducial howto here.
The bridge TUIO → Flosc → Flash is now being replaced by the bridge TUIO → udp-tcp-bridge → Flash. The latter method renders the transformation of TUIO messages to a proprietary XML dialect obsolete. That speeds up the connection of the TUIO producer (e.g. Touchlib, CCV or Touché) to the Flash application itself (e.g. Vispol, Volvelles) and thus reduces lag.
Hopefully, TUIO producers will support the output of TUIO via TCP natively soon (as far as I know at least Touché does). However, you are on the safe side if you use memo’s cross platform, open source, C++ UDP TCP bridge.
The TCP tuio AS3 classes have been downloaded and adapted for the additional support of fiducials from Touchgateway.

In his Bachelor thesis Frederic Frieß enhanced the original Touchlib TUIO AS3 classes with support for fiducials (or to speak in TUIO terms with support for /tuio/2dobj messages).
Thus, the Touchlib’s TUIO classes can simply be replaced with Frederic’s classes and everything should still work as before. However, there is one slight change in the package structure: the TUIO classes are now lying inside the package tuio and not in the package flash.events.
I have made Frederic’s Tuio Fiducial AS3 classes available on Google code in a project called fiducialtuioas3.
If you want to use reacTIVision fiducials in Flash, Flex or Adobe Air you are heartily invited to use these classes in your private and professional project.
Finally, the Universitat Pompeu Fabra in Barcelona guys around Martin Kaltenbrunner released a special page for TUIO that explains the protocol in more detail and with some examples. In the past it had not been that easy to extract all necessary information from their TUIO paper.
Just in time, before they will hopefully release TUIO 2, which supports OSC via TCP and thus a support for Flash without the need for Flosc or Toxy as Flash does not support native connections via UDP sockets.
This video presents the results of the Bachelor thesis of Frederic Friess at the Vislab of the Wiesbaden University of Applied Sciences. I have been Frederic’s mentor under the guidance of Prof. Dr. Doerner for this work. Read the rest of this entry »
I helped Sensory Minds to build an interactive multi-touch and tangible media installation for a Werkschau of students from the Hochschule Pforzheim. Graduates are represented by objects that are provided with a fiducial on the underside and a picture of the work on the upper side. As soon as the object is added to the table, pictures of the student’s projects will be loaded and circularly arranged around the object. Those pictures can be browsed via multi-touch. If a user taps on a project picture all pictures to this project will be loaded and will be arranged on a second circle around the project images. Read the rest of this entry »
