Abstract
The T-RHYTHM system, that supports individual learners in playing or singing in solo or ensemble situations, is proposed. T-RHYTHM provides each learner the rhythm of music through tactile sense, and supports her so that she can recognize her own rhythm without being confused by other learners' performances or singing voices. The rhythm of the music given to each learner is determined based on a performance by an accompanist and transmitted to her vibration device via a wireless communication. The user studies of T-RHYTHM have been conducted in an elementary school in Chiba prefecture, in order to confirm how it can effectively improve learners' rhythm recognition skills.
