摘要

This study seeks to transfer pelvic movement characteristics in gait, to a sound design that appeals intuitively to a participant, and that aspires to map precisely and obviously (even subconsciously) to their cognition in recognising a clear association between the anatomical body part with a corresponding sound. The materials of the study use movement data taken from three-planar gait analysis, using an optical measuring system. Dimensions of gait activity in the pelvis have been tracked in pelvic (transversal) rotation, (coronal) obliquity and (sagittal) tilt. Parameter Mapping Sonification (PMSon) is the process of utilising the dimension of sound to reveal aspects of other, non-sonic dimensions. Many studies have explored the various forms of sonification, which can evidence effective uses in a broad range of movement activities. There are numerous examples where effective movement characteristics have been implemented to a sonic dimension, following a careful and logical transference of energy, and so creating a semantic coupling for the beneficiary. In this study the three-dimensional re-modelling of pelvis movements in normal gait, collating the data sets of rotation, obliquity and tilt are taken as graphs and transferred into a range of sound characteristics, such as amplitude, pitch, and various filters (e.g. low pass), additionally peaks and valleys in the graph are converted to sample triggers for sequencing percussion patterns. In future studies the sonic results will be applied to a range of participants to measure their psychological and physiological responses, ascertaining to what extent the PMSon works, how well pelvic movement relates to the sound, and to what extent this is fit for application in a larger-scale study for entraining movement behaviour.
