Abstract

We experimented with acoustic feedback designs to explore intuitive mappings used to guide stepping movements of walking in healthy subjects. The accuracy with which subjects reproduced a target movement based on alternative pre-programmed movement to sound mappings was compared. The most effective mapping produced a mean percentage error in either step distance or duration of approximately 12%. In additional experiments, we measured the relative accuracy of such movements based on visual feedback as compared to auditory feedback. Mean percentage errors (±std) in visual and auditory feedback cues were: Vision 11.5 ± 7.0; Audition 12.9± 11.8. Results indicate that, when played to their respective sensory strengths, visual and auditory feedback can be comparably effective in entraining for stepping movements.
