However, research has shown that a conflict might arise when a person attempts to use both their natural and additional arms, which could make it impossible to optimize performance. Therefore, we proposed a 3-arm motor skill training in VR to observe the change of subjects' behavior. Our results suggested that the proposed training may improve performance of 3-hand body and provide a possible approach for future research.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing -> Empirical studies in HCI; Virtual realityHuman centered computingEmpirical studies in HCIVirtual reality10.2312/egve.202212871-22 pages
