AHs 2025 Purrfect Pitch: Learning Musical Intervals through Audio-Haptic Feedback
Description
Learning to identify musical pitch intervals usually requires tedious rote practice. Purrfect Pitch offers a new approach: a wearable haptic vest that translates sound into touch. When users hear two musical notes, they simultaneously feel vibrations at corresponding vertical positions on their back—leveraging our natural "high/low" pitch metaphor. In a study with 18 participants, those using the audio-haptic system identified intervals 20% more accurately and 1.67 seconds faster than audio-only learners. However, the performance boost didn't persist after removing the haptic feedback, suggesting the vest enhances task performance but doesn't accelerate long-term skill acquisition.
