The purpose of this study is to explore the ethical situations that field workers can face in dance art work with AI, especially focusing on the 'body alienation' situation of dancers. The study focused on literature research on AI and body alienation, semi-structured one-on-one phone interviews involving engineers and dancers who have experienced related work in the actual field, and structured one-on-one written interviews involving choreographers. As a result, we discovered situations and types of body alienation that can occur, such as ‘human body instrumentalized for AI learning’, ‘body alienation due to differences in performance capabilities between humans and AI’, and ‘body alienation due to capital and power’. The body alienation that can occur at this time includes not only issues of portrait rights, intellectual property rights, and copyright, but also personal privacy, labor alienation, psychological alienation, and biological alienation. It is expected that this study will be used in various ways as a basic study examining ethical factors that should be considered in the workplace of dance art using AI.
