What is Augmented Reality?
Augmented Reality holds the potential to bring elements of the virtual world into the real world, enhancing the things we hear, we see and we feel.
It’s the bridge between the real world and the virtual world.
Augmented Reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are “augmented” by computer-generated or extracted real-world sensory input such as sound, video, graphics, haptics or GPS data. It is related to a more general concept called computer-mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer.
Augmented Reality enhances one’s current perception of reality, whereas in contrast, virtual reality replaces the real world with a simulated one. Augmented reality is used in order to enhance the experienced environments or situations and to offer enriched experiences. Originally, the immersive augmented reality experiences were used in entertainment and game businesses, but now other business industries are also getting interested about the the possibilities.
Augmented reality technology blurs the line between what’s real and what’s computer-generated by enhancing what we see, hear, feel and smell.
Several categories of augmented reality technology exist, each with varying differences in their objectives and applications.
Marker Based Augmented Reality – also called Image Recognition, uses a camera and some type of visual markers, such as a QR code, to produce a result only when the marker is sensed by a reader. Marker-based applications use a camera on the device to distinguish a marker from any other real-world object. Distinct, but simple patterns (such as a QR code) are used as the markers because they can be easily recognized and do not require a lot of processing power to read. The position and orientation are also calculated, in which some type of content and/or information is then overlayed on the marker.
Superimposition Based Augmented Reality – either partially or fully replaces the original view of an object with a newly augmented view of that same object. In superimposition based augmented reality, object recognition plays a vital role because the application cannot replace the original view with an augmented one if it cannot determine what the object is. One example could be a furniture catalogue. By downloading an app and scanning selected pages in the printed or digital catalogue, users can place virtual furniture in their home with the help of augmented reality.
