Augmented reality(AR) is a technology that allows the user to experience the physical world, with computer-generated digital information. Like virtual reality, AR adds layers of virtual input. But unlike VR, AR only adds some virtual information without creating an artificial environment to replace one. Also, it creates some input ranging from sound to video, graphics to GPS overlays, and more in digital content which response in real-time. Hence, it involves technologies like S.L.A.M (simultaneous localization and mapping) and depth tracking.
1. Marker-less AR
2. Marker-based AR
3. Projection-based AR
4. Superimposition-based AR
This science-fiction idea was rooted in 1901, although the term was first introduced in 1990 by Thomas Caudell. But Louis Rosenberg’s complex Virtual Fixture comes with a major update of AR in 1992. The ARQuakegame (2000) and the design tool ARToolkit(2009) was the most notable release of AR in the consumer world. But later, Microsoft’s HoloLens in 2015 brought AR belonging to the classical sense, while AR software became popular and affordable.
Augmented reality is the future since the growth we have witnessed is massive. Therefore, the future technology belongs to AR. In addition to that, it adds a layer of virtual information that allows us to take a look at this world differently. Its improved task efficiency and the output quality of user’s experience will be a key takeaway in the innovation world.
