A video of a large, augmented-reality, fire-breathing dragon flying over a baseball stadium is frequently shared on social media. While viewers were undoubtedly aware that this footage didn't actually show a real mythical creature's visit to a ball game, some social media users seemed a bit confused about what this video actually showed. Is it a hologram? CGI? Virtual reality? This video shows an augmented reality (AR) dragon. AR, which refers to technology that mixes the real world with computer-generated (CGI) images, is different from virtual reality (VR), the use of computer technology to create a simulated environment. Unlike a hologram, the CGI objects can only be seen via some sort of screen: According to information from Live Science and The Franklin Institute, respectively: In other words, this dragon didn't actually fly over this stadium. It was only viewable via a screen. This video was created by the company SK Telecom for the SK Wyverns' opening day (a wyvern is a winged two-legged dragon with a barbed tail) of the 2019 Korean Baseball Organization season. The dragon was visible on the stadium's large LED screen and home televisions. While the people at this game couldn't see this dragon with the naked eye, they were able to see this mythical beast via their phones. Korea.com reported that fans could also interact with the dragon by pressing the cheer button on a smartphone app: A second video of this augmented reality dragon was posted to the SK Telecom YouTube page. That video shows fans downloading this app and interacting with the dragon via their phones: In November 2019, a similar video supposedly showing a hologram lion roaring at stadium in Argentina went viral on social media: Again, this was not a hologram visible to the naked eye, but an augmented reality display that could only be seen on screens.
