In this study experiments were conducted to determine if a person could distinguish percussive audio loops by their fingertips using audio-driven tactile feedback. The audio signal was adapted to generate a vibration signal (tactile feedback) taking into account the limited capabilities of the tactile modality. A systematic approach to find the different adaptation parameters is discussed. The vibrations were created by an electrodynamic shaker mounted behind a touch-sensitive screen. Results indicate percussive loops are best distinguished if the source features (e.g., frequency spectrum) and sequence features (e.g., rhythm) are maintained.
