Phantom Lab (Barbis Ruder, Lona Gaikis, Walter Lunzer) Phantom Lab I-III (2022) INTRA Project: Towards an Aesthetics for Prosthetics: How to Hack Medical Product Engineering for Artistic Research and User Benefit   In 2020, artist Barbis Ruder, philosopher Lona Gaikis and industrial designer Walter Lunzer, founded the Phantom Lab to bring their disciplines – arts, design, and philosophy – into conversation in order to look from their transdisciplinary artistic viewpoint at the blind spots that haunt medical engineering. They focus on the example of hand prothesis development. In this text and poster the set-up and learnings of the Phantom Lab I-III workshops in the artistic field are described.
