The invention relates to the field of VR technology, in particular to a VR-based head-mounted display system. The VR-based head-mounted display system comprises a host computer and a head motion tracking device, an eyeball motion tracking device, a voice recognition device, a hand motion recognition device, a touch generator, a visual scene generation system, and a three-dimensional virtual soundgeneration system respectively connected with the host computer. Compared with the prior art, a virtual helmet display of the VR-based head-mounted display system greatly enhances the immersion depthof a user so that the user can obtain more information from the environment having both visual experience and auditory experience, thereby further enhancing the sense of immersion and interaction.
