Abstract
This paper presents a set of real-time sonifications of heart
rate variability in the context of biofeedback. The objective
of the study is to explore new ways in providing biofeedback
information rather than the typical graphic displays in
medical products. Four different auditory displays were
created by mapping heart rate variability to timing variations
of the sound. In the experiment, ten subjects completed five
tests of biofeedback training with four auditory displays and
one graphic display. During all tests, the heart rate variability
and respiration data were recorded for evaluation of the
effectiveness of biofeedback training. Subjects were also
asked to rate their subjective experience after each test. The
results suggest that most subjects could achieve a similar
training effect with auditory feedback compared to graphic
feedback. Although the user experience of auditory feedback
did not meet our expectations, some subjects were
enthusiastic about the direct auditory feedback. We discuss
these results and provide a description of what is learnt from
our design explorations.
