In recent years, online shopping has increased rapidly. Currently, this trend is also being fuelled by the Covid 19 pandemic and, according to many experts, will continue unabated in the future. As a result, e-commerce in the B2C sector recorded record figures in 2021 in terms of turnover (9.6 billion euros, cf. Handelsverband Österreich 2021a) and in terms of postal parcels delivered (76.5 million euros in the first quarter, cf. Rundfunk...

The compelling story of self-improving machines which become exponentially smarter up to inconceivable intelligence has inspired some of the best science fiction literature [1–3], but is also taken seriously by many researchers. This story is however based on empirical observations of seemingly exponential processes such as Moore’s law in the semiconductor industry, and contains multiple fallacies concerning self-improvement of...

We have analyzed the game mechanics of GoPop!™ Roundo by FoxMind. For the simpler variant independent of the previous move, the full game tree can be stored in 12 gigabytes and generated in about 15mins. However, just evaluating local probabilities at each step performs very badly against random play and multiple random self-plays until known outcome, two reasonable baseline benchmarks. Evaluating the game tree by self-play to the end -...

Since 2012 we have been building the augmented reality system Magic Mirror based on Kinect V1 and V2's native API. It relies on the magic mirror metaphor, where a large screen shows a mirrored camera view with overlaid graphical elements. In our case, it shows a different face mesh over the person's face which reliably tracks face poses in real time while leaving the eyes and mouth of the person visible for interaction and to improve...

Almost since humans started thinking, they thought about creating artefacts that think as well. The earliest written record of the creation of such an artefact, the Golem, dates around 1630-1650. It is not renowned for its intelligence, however, and easily tricked by its creators. Frankenstein by Mary Shelley described perhaps the first artefact that surpassed its creator in intelligence (not to mention mercifulness), however its base...

I was motivated for this project by my - at project start - two-year old daughter who always
hid her toys under the couch. It was quite hard finding out what lay down below. So we built a robot that could be
remotely controlled by any Android device via Wifi, drove under
the couch, looked at the toys, and moved out what toys it found. It was
just under 6.5cm tall, streamed high-quality H264-encoded video in real time,
was controlled with a...

Installation of TCserver
TCserver controls the robot, LEDs and cameras and receives commands via Bluetooth or Wifi. For V1.21 (R2X) we distinguish the MASTER Raspberry Pi with connected motor controller and the SLAVE. For the robot models with only one RPi, we conveniently also define it as MASTER.
The following three steps must be executed for the V1.21 (R2X) robot on MASTER and SLAVE, otherwise only on the one.

We developed - initially for a customer and later self-financed - a system for eye tracking using video data from off-the-shelf USB cameras. Initially the system needed a calibration per session. In the mean time there is also a calibration-free version and is also used in our Augmented Reality research for 3D face recognition. The system has the following advantages versus commercially available eye tracking systems that use active sensing...

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 technology that made...

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 doubt, have your voltmeter ready and...

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 species recognition, named entity recognition, ranking and...

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 legged-robot league and can...

Since 2000, I am aware of Simpson's paradox. Although well known to
statisticians and machine learning researchers, it is practically ignored
in all business intelligence systems which are based on aggregated numbers (Kennzahlensysteme) - and practically all existing systems fall into this category.
Simpson's paradox: when data on different aggregation levels yields apparently contrary interpretations. Consider following results from a...
