I was involved in no less than 4 papers at this year’s NIME conference in Ann Arbor, Michigan. K. Nymoen, A. Voldsund, S. A. v. D. Skogstad, A. R. Jensenius, and J. Tørresen. **Comparing motion data from an iPod touch to a high-end optical infrared marker-based motion capture system **[PDF] The paper presents an analysis of the quality of motion data from an iPod Touch (4th gen.). Acceleration and orientation data derived from internal sensors of an iPod is compared to data from a high end optical infrared marker-based motion capture system (Qualisys) in terms of latency, jitter, accuracy and precision....

I have been using Google Scholar as one of my main sources for finding academic papers and books, and find that is has improved considerably over the last few years. A while ago they also opened for creating your own academic profile. It is fairly basic, but they have done a great job in managing to find most of my papers, citations, etc. Now also Microsoft has jumped on academic search, and has launched their own service....

Yesterday I held a workshop on music-related motion capture at this year’s Art.on.Wires. The workshop was quite similar to the one I held in Trondheim a couple of weeks ago. Trond Lossius held workshops on Jamoma and surround sound, and there were many other interesting workshops as well. Below are some pictures from the festival:

I will participate in a motion capture workshop at the Norwegian University of Science and Technology (NTNU) tomorrow. My contribution will consist of the following: Lecture: Introduction to motion capture (in music analysis and performance) Demo 1: Working with video analysis using the Musical Gestures Toolbox Demo 2: The Xsens MVN BioMech mobile mocap suit Workshop: Analysis and performance with Wii controllers, Phidgets accelerometers and Kinect Below are various resources....

Update 1 December 2022: You may want to check out a newer version of this figure that I made for my latest book. For some papers I am currently working on, I have taken up my interest in definitions of different types of disciplinarities (see blog post from a couple of years ago). Since that time, I think talking about the need for working interdisciplinary has only increased, but still there seem to be no real incentives for actually making it possible to work genuinely interdisciplinary....

On Thursday we are organising the first Norwegian Championship of standstill at University of Oslo. This is part of the University’s Open Day, a day when potential new students can come and see what happens on campus. Besides the competitive part, the championship is (of course) a great way to gather more data about how people stand still. The art of standing still is something that has been a great interest of mine for the last year or so, and I have been carrying out different types of smaller experiments to understand more about the micromovements observed when standing still....

Yesterday I was teaching a workshop on laptop orchestra performance for the students in Live electronics at the Norwegian Academy of Music. I usually start such workshops by playing the piece Clix by Ge Wang (see e.g. here for a performance of it). It is a fun piece to play, and it is nice to show the students something else than Max patches. Unfortunately, while setting up for the workshop I had problems getting Chuck to work on my new laptop....

When creating figures for papers written in LaTeX, I have found it aesthetically unpleasing to have different fonts in the figures than in the text. Most figures I create in either OmniGraffle or Matlab, and here I have relied on regular OSX fonts. Fortunately, I have discovered that it is possible to use LaTeX fonts in OSX. Apparently, this is now included as a feature in the latest version(s) of the MacTeX distribution (?...

A couple of days ago I presented the paper “Motion-sound Interaction Using Sonification based on Motiongrams” at the ACHI 2012 conference in Valencia, Spain. The paper is actually based on a Jamoma module that I developed more than a year ago, but due to other activities it took a while before I managed to write it up as a paper. See below for the full paper and video examples. The Paper Download paper (PDF 2MB) Abstract: The paper presents a method for sonification of human body motion based on motiongrams....

Travelling on the excellent (and frequent) Valencia metro this morning, I noticed that music was played in the background. Or, to be more precise, I noticed it after a while. I started my travel in the middle of the city centre in the rush hour, so most of the soundscape was composed of three elements: the noise of the metro cars while moving the noise of the massive ventilation system inside the metro cars (I am not really sure why they made so much noise, but at least the air was fresh) the noise of people speaking Since most people left at the stations in the city centre, I was travelling more or less alone the last part out to the airport....
