Reconciling Being in-Control vs. Being Helped for the Execution of Complex Movements in VR

摘要: Performing motor tasks in virtual environments is best achieved with motion capture and animation of a 3D character that participants control real time perceive as being their avatar the environment. A strong Sense Embodiment (SoE) for body not only relies on feeling own (body ownership), but also moves world according to will replicates precisely movement (sense agency). Within frame mind our specific aim demonstrate can even be programmed better at executing given task or perform normally difficult impossible execute by user. More specifically, experimental consists asking subjects follow hand target animated using non-biological motion; unnatural nature leads systematic errors subjects. The challenge here introduce subtle distortion between position hand, so succeeds performing while still letting believe they are fully control. Results two experiments $(\mathrm{N}=16)$ show implementation function, we name attraction well, successfully led report (agency) embodied ownership) when was above threshold detect. Furthermore, progressive introduction (starting without help, introducing go) could further increase its acceptance.
