心拍ゆらぎにより揺れが変化するアクティブロッキングチェアの開発

抄録

The purpose of this study is to realize the comfortable swinging fitted in the condition of each individual person. A simple active rocking chair is developed, which changes the swinging with the heartbeat fluctuation of the person. The active rocking chair is driven by a solenoid for the safety and the silence. The swinging is strengthened, when the period of the heartbeat is lengthened, and it is weakened in shortening case. The swinging is evaluated using the 16 scales questionnaire which was developed for an evaluation of a comfortable swinging on the basis of the SD method. As the result, it is confirmed that the comfortable swinging is realized by the developed active rocking chair. Then the acceleration near the ear of the rocked person is measured in order to examine features of the comfortable swinging with the feedback of the heartbeat fluctuation. And, it is clarified that the power spectrum of the envelope of the acceleration waveform shows “1/f fluctuation”.
