When Media Environments Become Real

It all started with the alpenhorn. An elderly woman entered the auditory and played this traditional Swiss instrument. The view from the university to the mountains was also nice, although slightly cloudy on this particular day. I would rather see that version with the blue sky. And I would rather not see the bear living in captivity for the sake of being heraldic animal of the city. The conference (see website) is not particularly interesting, the theme encompasses all kind of media shifts, television, e-commerce, and virtual environments are all examples for that. Read more →


I did it again. I revised my paper completely and resubmitted it to the journal of my choice. Compared to the original submission, the haptic evaluation part was removed, a structural reorganization took place, and many improvements in argumentation and plausibility were added. So now it is in the editorial pipeline again. This paper describes evaluation experiments for visual and auditory feedback in a virtual obstacle walking scenario. Two studies with healthy subjects were carried out using the actuated gait orthosis Lokomat. Read more →

How to add logos to all your pages with LaTeX

Given the problem that you want to put one or several logos in your document header, I found the following solution. All the lines have to be inserted in the document preamble, meaning before the \begin{document} line. You will need your logos in the appropriate format (in most cases EPS, pdflatex requires PDF, PNG, or JPG) in your document folder. I will assume logo1.eps and logo2.eps are the file names for the two logos. Read more →


A new topic which we recently entered for our virtual rowing project in the M3 lab is the assessment of psychological states (stress, engagement, frustration) with physiological parameters (heart rate, skin conductance, brain activity). The term psychophysiology describes this scientific area best. It is actually very interesting for us from a scientific point of view. We will investigate rowing subjects who are confronted with virtual audience or competitors. Our hypothesis is that they will react as in real life, leading to a change in performance, e.

Institute Overview

In the past days I’ve spent some hours with Illustrator to create an overview image of our research activities. The result is now on our group homepage, I used opacity masks extensively.

Paper Submission

It is done! At least for the moment. Today I submitted my first journal publication. It will now be reviewed with the possibilities of acceptance or rejection. But despite of this uncertainty I feel quite relieved, as it has disappeared from my desk and now is on the desk of other people. To give you a short impression, I will add the abstract. This paper describes evaluation experiments for visual, acoustic, and haptic feedback in a virtual obstacle walking scenario applied to gait rehabilitation. Read more →

Incomprehensible Abstract

As an example for bad scientific writing, I would like you to read the following abstract. It consists of only two sentences. Five or six would have been better.

IEEE PDF Express

In the past I very often had the impression that most of my friends believe I have an easy life as scientist. And I must admit, most things are cool being a PhD student here in Zurich. But some are not. And one of the most detestable ordeals on my way to scientific achievement is the IEEE pdf express tool. Because you need to get past that to submit a paper for the conference proceedings.

Why we need virtual environments for motor rehabilitation

I recently stumbled over the publication T. Mulder: A Process-Oriented Model of Human Motor Behavior: Toward a Theory-Based Rehabilitation Approach. Looking for an underlying red line in the introduction of a planned publication by me, the article fitted extremely well in motivating the usage of virtual environments and other advanced techniques for gait rehabilitation. It is based on an integrated model of human motor performance, what I also found in Motor Learning and Performance. Read more →
