Virtual reality technology has since the 1990’s that time, the family home around the world talking about the making of the large VR but most have failed for various reasons: the computer’s processing power not strong enough, not many communities, expensive, not good experience (this is the biggest reason). Nintendo, extremely familiar names, has also launched a device called the Virtual Boy in 1995.
