Just how Advanced is Virtual Reality?

My term project is going to be about virtual reality. In the past few years, the use of the term "Virtual Reality" have come across many discussions. Thanks to advancing in technology, the use of virtual reality is now expanding into many different sectors of private and public lifestyle. It is being used for military purposes, education, medical training, and most popularly, gaming and entertainment. Right at the heart of NYC, lies VR World NYC where it is open to the public to anyone who desires to see and witness the effects of VR firsthand, primarily in entertainment and gaming functions. For my project proposal, I am going to briefly describe the history of VR and what caused it to finally emerge in the 2010s, followed by its use and impacts in several fields. Also, VR has negative effects on human health as the "virtualized reality" seems to play games with the brain after it has been experienced. I will also dwell upon its effect on communication, digital media, and sociology.
