The purpose of the study on wearable power assist devices is to develop support system for those who require care. The power assist device is get heavy when the degree of freedom increases so as to prevent disturbing the movement of the human. The purpose of this study is to extract the major modes of human meal behaviors for design of the light weight power assist device by calculating the optimal degree of freedom through mode analysis. Measurement of meal behavior was used motion capture. The major modes were extracted by the mode analyses using singular value decomposition method. As the results of the analyses, the both shoulders flexion and extension motions, the left shoulder adduction and abduction, the left elbow extension and flexion were identified as the major modes of human meal behavior. The results will be utilized for the optimal mechanical design of the light weight wearable assist device.
