In order to develop useful assistive devices, it is necessary to analyze and understand the function of human. In this study, the activities of daily living were recorded and the performance of dominant and non-dominant hand was classified according to ICF (International Classification of Functioning, Disability and Health) approved by WHO. As a result, it was revealed that the use of both hands makes a great difference. It will be reasonable to design assistive devices such as prosthetic hands for non-dominant hand to have less function (degree of freedoms, payloads etc.) than assistive devices for dominance hand.
