Recent advancements in robotics and wearables made it possible to augment humans with additional robotic limbs (e.g., extra pair of arms). However, these advances have been dispersed among different research communities with very little attention to the userâs perspective. In this work we take a first step to close this gap. We report on the results of two focus groups that uncovered expectations and concerns of potential users of Supernumerary Robotic Limbs (SRLs). There is a wide range of applications for SRLs within daily usage contexts, like enabling new perceptions, commuting and communication methods as well as enhancing existing ones. Yet, several requirements need to be met before SRLs can be widely adopted, such as multipurpose design and adequate sensory feedback. We discuss how these findings influence the design of future SRLs.
