Digital Trend<\/a> is \"the interaction of superimposed graphics, audio and other sense enhancements over a real-world environment that\u2019s displayed in real-time\".<\/p>\nBy this definition, AR can refer to some technologies which have already existed for years. Take for instance sports telecasting where you see colored lines drawn against real-time gameplay of say, a soccer match.<\/p>\n
These lines may be used to indicate the offside boundaries in which the players must not cross or to show the movements of the ball or players. AR is not to be (commonly) confused with Virtual Reality (VR)<\/strong>, where the primary goal is to replace<\/strong> the real world with a simulated one.<\/p>\nWe often take such existing technology<\/strong> for granted because they are so prevalent and commonplace<\/strong> that we don\u2019t associate them with what we normally assume as \u2018high-tech\u2019 AR<\/strong>.<\/p>\n
