I am going to present a few projects on my blog which I like. This post introduces the Umami project of Florian Cannon, Robert Fläck, Florian Gondolf, Mischa Korn, Daniel Pehnec, Sarah Martens, Tara Staton from Darmstadt University of Applied Sciences. umami proposes the the integration of multi-touch surfaces in kitchens of the future for the support of cooking.
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.
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 2: Now, another TUIO overlay is available for the Surface (2).
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.
The second multi-touch table, that I have built is called The Virttable, which stands for Versatile Illumination Research Touch Table.
This table is the property of the department for Design, Computer Science and Media (DCSM) of the Wiesbaden University of Applied Sciences, which provided me with the money for the components of the Virttable. (Actually, we had student fees for a short time in Hessen/Germany. From a part of these student fees the Virttable has been built. Thank you, dear students!!! There’s no cent of public money in the Virttable.) Amongst others those parts include:
- a Panasonic PT AX 200 projector
a Unibrain Fire-i Firewire camera
- a Pointgrey Firefly MV firewire (mono version) camera
- a B+W infrared filter 092 (low-pass, lets transmit 90% of infrared light above 730 nm)
lots of Osram SFH 485P infrared LEDs
- 162 Osram SFH 4550 infrared LEDs for FTIR illumination Their min. radiant intensity is 400 mW/sr at 100mA while the min. radiant intensity of a SFH 485P LED is 4.5 mW/Sr at 100mA. Taken the LED’s half angles into consideration (3 for the SFH 4550 resp. 40 for the SFH 485P) this means that the SFH 4550 has around 6.5 times more light than the SFH 485P.
- Six high power infrared LEDs with 4 led’s on one dye (Aculed VHL IR 4-chip High Power LEDs) for Diffuse Illumination
two panes of acrylic glass(I burned the surface of the second pane, a Plexiglass EndLighten pane, while trying to apply a Lexel/Toluene dilution on top of it)
- A standard acrylic glass
- MDF boards for the box
The computer that I have used in the Virttable is my Mac Mini.
