ダブルストローク時の指先力を計測可能な3軸力センサ内蔵ドラムスティックデバイス

In this study, we report on the drumstick device for measuring 3-axis force of the fingertip in double stroke. This device consisted of 3-axis force sensor installed in drumstick. The 3-axis force sensor is capable of detecting normal force and 2-axis shear force with the sensitivity of -22.3 mV/N, -64.2 mV/N and 60.0 mV/N. This device can measure the impulsive force and 3-axis force in playing the drum. The average force of the normal force was calculated, and the normal force indicated the largest amount of force. When the average force are measured at each tempo, that average force was increased linearly to 150 BPM. However, it was decreased from 28.4 N to 4.17 N in range of 150 BPM to 180 BPM. From the results, it was confirmed that the method of controlling stick depend on tempo. Therefore, it was suggested that the performance of the drumming could be evaluated by using this device.
