Consideration of Embodied Expertise Transfer Process in Manufacturing-site-Through the development example of wheelchair for the Physically Disabled Users

This paper examines the embodied expertise transfer process between disabled persons and developers in the electric wheelchair manufacturer's development workshop for disabled persons. What we found in this study is listed as follows. 1) The embodied expertise of able-bodied persons is metacognitively verbalized through the “intercorporeality (intercorporéité)” between able-bodied and disabled persons. 2) The embodied expertise that has been metacognitively verbalized is transferred from the craftsmen to the tools used by the disabled persons. The embodied expertise not yet metacognitively verbalized by the disabled persons and the embodied expertise already transferred have and maintain a complementary relationship. 3) The embodied expertise not yet metacognitively verbalized by the disabled persons further accelerates the process of metacognitive verbalization of the embodied expertise of able-bodied persons through the intercorporeality between able-bodied and disabled persons.
