Description

Virtual reality display system {VIRTUAL REALITY DISPLAY SYSTEM}

The present invention relates to a virtual reality display system, and more particularly, to a virtual reality display system using first and second user terminals and a head mounted display.

A display device has been developed that gives the same effect as viewing an image over and over.

Most of these display devices are called Head Mounted Display (HMD) because they are worn on the head in the same way as glasses. In general, the HMD uses a precision optical device included in the user's eyes.
