Recently, I made my first steps in Adobe Air 2. As Air 2 is still in Beta version (currently in Beta 2, which was released on February 2, 2010) there still could be some problems when working with it.

Recently, I have been working on the Touchlib in order to refine some things, which always bothered me and to add some things of which I think that they would come in handy e.g. a full-grown Pointgrey Flycapture2 filter that allows me to edit the Pointgrey Firefly MV camera’s settings in a way that I described here.
After being able to compile the Touchlib I quickly grew curious about what all those blobconfig parameters in the Touchlib’s config.xml REALLY do.

As already mentioned in this post, we presented Vispol at the booth of the state of Hessen/Germany at the fair “Moderner Staat” in Berlin on 24. and 25. November 2009. Vispol has been shown on the round multi-touch and TUI table from Sensory Minds.
Here are a few photos from the fair. Please apologize the poor quality of the photos as my camera did not see the sense in making proper use of its auto-focus functionality.

My software Vispol will be shown at the booth of the state of Hessen/Germany at the fair “Moderner Staat” in Berlin on 24. and 25. November 2009.
It will be shown on the new really cool round [!] multi-touch and TUI table from sensory minds.
I will be there on both days.
Recently I had the problem that my Flex code, which used the ResourceManager, would not find the resource bundle, which contained all resources for my application. However, the application compiled but it would always crash whenever the first time a resource should be loaded. I checked my compiler arguments a 1000 times but everything was correct and did work well in another Flex application. The problem was that my resource bundle was not present in the ResourceManager, it just did not load it.

In terms of the NUI research project Squidy at the Konstanz University the TUIO overlay SurfaceToTuio has been developed for Microsoft Surface. Download the SurfaceToTuio component from the sourceforge project site (or via direct download).
SurfaceToTuio is available as source code only (there is no executable). However, you can just upload the SurfaceToTuio folder to your Surface, doubleclick the Visual Studio project and compile it in the Surface’s Visual Studio right away.
Finally, a decent software interface for a decent hardware.
Update: The project of the Konstanz University has a bug, which has been resolved by Julian. Check out the stuff in his repository.
Update 2: Now, another TUIO overlay is available for the Surface (2).

Some time back, I’ve bought some infrared blocking foil for the Virttable from the German foil store Ifoha. Infrared blocking foil is an approach for the blocking of ambient infrared light (e.g. from a light bulb or daylight) ONLY in a FTIR multi-touch setup as it blocks light that comes from above the table. I.e. in DI your hands reflect light that would be blocked by an IR blocking foil.

I am going to present a few projects on my blog in which I collaborated in one or the other way. This post introduces Fabio Campos‘s VotkA (Visualization of the k-means Algorithm) project of the course Visualization in the Master’s studies of Computer Sciences at the RheinMain University of Applied Sciences. Fabio’s project is a 3D visualization of the k-means algorithm applied to Fisher’s dataset. The user can interact with the visualization via reacTIVision/Fiducials or the OSCRemote application on the iPhone/iPod Touch.

In VotkA users can interact with a three-dimensional cluster analysis visualization via a Tangible User Interface (TUI), the iPhone app OSCRemote or both in parallel. The TUI is provided by a small box that is technically based on Seth Sandler’s cheap multi-touch pad (you can see the box in the youtube video at the end of this article). On top of the box fiducials from reacTIVision are being tracked. Whenever a fiducial is being recognized a TUIO message with the fiducial’s id, position and rotation will be sent to VotkA.

BumpTop is a Windows Explorer-like application that offers intuitive gestural multi-touch interaction paradigms with piles of files and folders. Additionally, it has a 3D space in which you can navigate and decorate your workspace. You can copy files to and from your usb stick, to Facebook or you can send them via mail. It seems to be integrated well in Windows 7.
Very interesting: Surface tracks shapes with its vision system. There are five cameras in the Surface. The system has a very high resolution (dice can be tracked). Surface uses high-power leds with a mirror system.
