Virtual reality (VR) allows a person to interact with a three-dimensional image or environment through the use of display, optical and sensor technology, in connection with powerful graphics and CPU. Wall Street has high expectations for the market potential of VR; much depends, however, on the results in the sales report. I would like to discuss the reasons behind the figures of the User Performance (UX) of VR HMD. However, this is not a formal study but rather a light recollection of personal experience, observations and interviews.
