In an aimed-motion experiment with 24 participants, real and virtual targets were alternated while virtual-hand representation (realistic hand or abstract sphere) and hand offset (20 or 40 cm) were varied. The study combines transition time, movement dynamics, trajectory deviation, proprioceptive drift, embodiment, and cognitive-load measures. Participants generally adapted the hand they used to the target modality regardless of representation and offset; detailed analyses show that a realistic virtual hand can increase embodiment while modestly affecting initiation and trajectories during the transition back to the real hand.” summary: “How people switch between a real hand and a displaced virtual counterpart in AR.” tags: [] featured: false url_pdf: ‘https://hal.science/hal-05712909/document' url_project: ’’ projects: [astral]
