Supplementary Material for "Interactive sonification of German wheel sports"

Hummel J, Hermann T, Frauenberger C, Stockman T. Supplementary Material for "Interactive sonification of German wheel sports". Bielefeld University; 2010.<img src="https://pub.uni-bielefeld.de/download/2698330/2702781" width="400"> The 3 pictures show a sequence of a "Basic rock" movement. Our sonifications were able to improve the accuracy of performing this movements. Details can be found in the paper. This paper presents the design, implementation and evaluation of a sonification system, which gives real-time auditory feedback to a performer who is carrying out moves on sports equipment called a German wheel. The system, which is implemented in the programming language SuperCollider, uses a magnetometer to collect data about the motion of the wheel. Parameters of this motion are then transformed into sound to give real-time feedback to the performer. The aim of the project is to examine whether such additional convergent audio feedback can lead to an improved performance of wheel moves. The design and implementation of four different sonification approaches is discussed, two of which were chosen to conduct an exempla study. The study was carried out with a group of seven novices and four experts and shows a significant positive influence of one of the sonifications on the performance of the given task by the experts
