To generate critical and new insights into our value system in human-centred societal challenges the experimental approach of Research through Design and the power of critical disability studies explore philosophical and strategic possibilities to understand the concept of co-Ability. I introduce the term ‘co-Ability’ rooted in the critical approach of posthuman disability studies outlined by scholars such as Rosi Braidotti (2013). It serves as a broad an umbrella term under which we can reconsider the potentials of various entities (biological and artificial) enhancing the shared competence rather than dwelling on the oppressive nature of human-centred norms.

By analysing the literature review, this thesis addresses the reflective symmetry in key elements between disability studies and design approaches, questions the validity of a homogenous human need and reflects instead on how co-design can become a driving fuel for generating possibilities.

Identifying how design helps to improve the experience of being human, and not necessarily the user experience of a disabled person in prosthesis design development highlights the constraints of seeing a prosthesis as a process instead of a product. To investigate through personal values and situated concerns, the research settled on a case study of prosthesis development with a discursive and self-reflective process. It actively contributed to a better understanding of embodied thoughts on relationships. With the methodological approach of the co-design framework, I point to the junctures where technology, bodies, and cultural theory intersect in a decentralised soft assembly in which disability, technology, and design act as equal partners in determining co-Abled formations.
