This work aims to evaluate the performance and effect of a Human -Computer Interaction (HCI) system in the Metaverse with real-time interaction and immersion. This work introduces the Metaverse with HCI functions of 3D face reconstruction, handshake and hug, multi-user synchronous editing environment, all information is stored in the blockchain. The performance of the HCI functions are also evaluated. The results demonstrate that the overall correct rate of the subjects by the HCI system is 95.45%. Users' social acceptance of VR interactive systems, action interaction usability, user emotions, and user satisfaction all show high scores. This work contributes to the performance evaluation and optimization of the HCI systems in the Metaverse.
