要約(英語): We developed an analyzing system for tremor using the three-axis accelerometer built into the Wii Remote in 2008. We propose a theory of estimating the tremor amplitude and mounted it in our system. The aim of the study was to study of errors in tremor amplitude estimates. To test our system using a small accelerometer (WAA-006), mechanical oscillations generated by an oscillation generator were sent to a small accelerometer that was attached to the device. The oscillating amplitude was set at 0.5, 1.0, 1.5, and 2.0 cm, and the oscillating frequency was varied from 1 Hz to 15 Hz in steps of 1 Hz. The relative error of the amplitude estimates calculated from the accelerations measured by the WAA-006 was 103.9 % at 3 Hz and 1 cm. Since this experiment covered the measurement range of the accelerometer, we were able to present the limits of amplitude measurement and analysis by the accelerometer.
