abstract = {Recent work across HCI/HRI and wearable robotics has investigated how people control and perceive extra body parts in both virtual and physical settings. Virtual embodiment in XR has shown that users can experience ownership and agency with non-anthropomorphic avatars, while wearable robotics has introduced supernumerary limbs such as third arms and robotic tails. Despite these shared goals, connections between findings remain limited because VR and hardware studies rely on different assumptions about sensory feedback, human perception, and physical constraints, making insights difficult to transfer across contexts. This workshop brings together researchers in XR, wearable robotics, haptics, and neuroscience to explore how to foster embodiment and adaptation with augmented body parts, and how to bridge virtual embodiment to effective use with wearable devices. Through a keynote, brief position shares, and two hands-on group activities, participants will examine control mappings and sensory-feedback strategies and identify which aspects of VR-based embodiment realistically transfer when accounting for hardware limits, sensor variability, and cognitive load. Ultimately, the workshop aims to articulate a focused research agenda connecting VR-based insights to feasible wearable robotics implementations, enabling future work on augmenting the human body with new parts and capabilities.},
