Yesterday I wrote about the 4 papers I was involved in at this year’s NIME conference in Ann Arbor, Michigan. The one I was the first author on was entitled The music ball project: Concept, design, development, performance, and is mainly a historic write-up of the work I have been doing on developing different types of music balls over the years, including various handheld music balls, the Music Troll, Big Buoy and the ADHD ball.

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.
