Gippert M, Heed T, Hermann T. Speed sonification in a unimanual timing and a bimanual coordination tapping task. In: Bresin R, Hansen K, Pauletto S, eds. Proceedings of ISon2019, the 6th Interactive Sonification Workshop. Stockholm, Sweden: Interactive-Sonification.org; 2019.This paper introduces systematic research on how uni- and bimanual tapping tasks can profit from interactive sonification of hand-surface interactions to support coordination. To that end, we developed a new experimental platform featuring a web app that allows multi-touch tablet-based interaction for sonification experiments. We present and discuss two experiments to test tap-interval-to-tone-frequency-mappings, to assess their ability to support rhythmic, resp. polyrhythmic tapping. The results, although negative with regards to our initial hypothesis, provide guidance for subsequent experiments to better understand how sonification can best be used to support coordination tasks, particularly in motor control contexts that involve discrete, goal-directed movements
