I am happy to announce that the ZigFlea board is currently available from Seedstudio. This board is the result of the Master’s thesis of Øyvind Hauback, whom I co-supervised at fourMs. The main point of the board is to provide an easy way of using ZigBee wireless communication together with Dan Overholt’s CUI32Stem sensor interface. ](/images/2012/09/P2171169.jpg) The ZigFlea wireless board, as sold from Seedstudio. ...
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. We identify some rotational drift in the iPod, and some time lag between the two systems. Still, the iPod motion data is quite reliable, especially for describing relative motion over a short period of time. ...
