Area of Science:

  • Physiological monitoring
  • Human-computer interaction
  • Bioacoustics

Background:

  • Heart rate variability (HRV) is a key indicator of physiological states, including stress and cognitive load.
  • Music has demonstrated therapeutic potential, influencing psychological and physiological well-being.
  • Existing methods for conveying physiological information can be intrusive or limited in scope.

Purpose of the Study:

  • To develop and evaluate a prototype system for indicating heart rate using musical data.
  • To explore the biofeedback effects of music-based heart rate representation on workers experiencing mental workload.
  • To assess the feasibility of using music as an unobtrusive information channel for physiological data.

Main Methods:

  • Real-time heart rate data acquisition and processing.

  • Auditory output of heart rate information through a sound source, creating a musical representation.

    • Main Results:

    • Successful prototype development demonstrating real-time heart rate to music conversion.
    • Evaluation of the system's biofeedback effects on workers under mental workload conditions.
    • Preliminary findings suggest music-based feedback may influence physiological responses.

    Conclusions:

    • A novel system for heart rate indication via music has been developed and evaluated.
    • Music-based biofeedback presents a promising, non-disruptive method for monitoring physiological states.
    • Further research is warranted to fully explore the therapeutic and performance-enhancing potentials of this approach.
