How to bluetooth-enabled your remote car. This is a step-by-step instruction on how to switch any common RC car to bluetooth control - i.e. creating a bluetooth-controlled car - like the one on the right, which was donated by my dear brother after years of collecting dust on his shelf. Although the steps seem quite simple and straight-forward to me, experience has dictated that the human capacity for miscomprehension is boundless - if in...
Intelligent Go Board. In 2003, we built a prototype 8x8 board which records Go moves during normal play, thus ensuring that a full game record is available for each game. No special stones are necessary, no holes need to be drilled through the board - it is a nice example for Ubiquituous/Pervasive Computing. The technology used then was a capacitive matrix array, now made famous by its use in the iPhone and Android mobile phones - it's the...
Wooden Easter Ratchet. Surprise your friends with this original wooden ratchet!Ratcheting is a well-known tradition since 1482. It creates lots of noise by turning a wooden ratchet - the faster, the better! 3D model and sound were captured from an original wooden easter ratchet originally built by my uncle. Our digital ratchet behaves just as a real one, but it's easier to take with you everywhere you go.NEW: Tablet support improved....
Text Mining in biological research literature (BioMinT). I was involved in the BioMinT EU-funded research project (2003-2005), which was concerned with text mining in biological research literature and online databases. I was directly responsible for: Implementation of a parser for fourteen online databases, transitive closure on the link graph, output as name pairs (synonyms) - 12 million pairs in all Research and development in biological...
Deflickering for high-speed HDTV video in realtime (deFlicker). We have built a prototype which removes flicker from high-speed HDTV camera recordings in real-time for the German company LiveMotionConcept. This complex flicker pattern is caused by brightness fluctuations in one type of widely used lighting sources. Ours is the first and only solution to this problem which does not involve replacing every single lighting source with properly...
Mobile Robot Toy Cat. In 1998/1999, we built a mobile robot toy cat based on the EyeBot-board and LEGO. While it was much fun and sometimes enlightening, ultimately we were sorely disappointed with the State-of-the-Art and now take only a cursory interest in this field. A short story to illustrate shortcomings of robotics technology: I had the pleasure to be one of the many spectators of RoboCup '99 in Stockholm which featured a Sony...
Electronic Site Diary. The documentation of large building projects becomes ever more important. Only a complete documentation enables you to fight unauthorized demands or enforce your own justified demands - and avoid legal issues. The site diary plays an important role here. Our electronic site diary offers a standardised documentation which corresponds to the state-of-the-art as to what is necessary for site diaries. It is fast and easy to...
Augmented Reality (AR). We develop AR system which combine realtime camera video with virtual objects or otherwise modify it. We are especially concerned with markerless AR where no special markers are needed and where virtual objects can be anchored to arbitrary images or general faces.
Software Autofocus for UVC cameras under Linux. We have created a stand-alone autofocus application for Logitech USB cameras with proprietary motor focus extension. This application will allow you to automatically set the appropriate focus for a given scene in a few seconds. The underlying focus-from-image estimation has been integrated into guvcview, and beats all published approaches (according to our tests and to feedback from its...
Color Blindness Correction and Simulator. See through the eyes of your red, green or blue colorblind friend!So you have a friend who is colorblind... how does the world look to him/her? With this app, you can see what it is like to be red, green or blue color blind. If you are colorblind yourself, you can also correct it - but first check which type of colorblindness you have by seeing whether you can tell the difference to the normal view.Now...
Automated Characterization of Osteoclasts via Image Processing Methods. During the Symposium Bridges in Pathophysiology we held a talk on our Osteoclast recognition system which was developed during the research project Holistic Pattern Recognition. The Symposium was held on occasion of the publication of the book Principles of Osteoimmunology (SpringerWienNewYork) where we also contributed one appropriate chapter. At this occasion we also...
Early-Warning System for Botnets. This project was initiated by Dr. Alexander K. Seewald and was conducted at the Research Lab Computational Technologies and Applications of the faculty for computer science of the University of Vienna under the leadership of Dr. Wilfried Gansterer. Previous research initiatives are focussed on the recognition and defense against unwanted or potentially harmful E-Mail messages (for simplification purposes named...
