Abstract
This paper tries to examine the relationship between humans and their prosthesis, and the how the technology have an effect on the human psyche. We have tried to illuminate the issues that prosthesis users experience through a phenomenological approach to semi structured interviewing, focus group interviewing and analysis. Through the dramaturgical sociology theory made by Erving Goffman and the social identity theory by Henri Tajfel, we try to explain possible changes in the personal and social identity of the prosthesis users. We can conclude that we have only obtained a partial answer.
