AR is the technology that adds digital content seamlessly over real-world objects.
This happens in real-time. This new technology blurs the line between what’s real and what’s computer-generated by enhancing what we see, hear, feel and smell. Augmented reality adds graphics, sounds, haptic feedback and smell to the natural world as it exists. Both video games and cell phones are driving the development of augmented reality. Everyone from tourists, to soldiers, to someone looking for the closest subway stop can now benefit from the ability to place computer-generated graphics in their field of vision.
In this generation, availability of information/data is in plenty but consumption of those data in a sane way is the real issue. Augmented Reality does a fabulous heavy lifting here. For ex: Picture yourself walking or driving down the street to find some good food joint on your vacation. With augmented-reality displays, which will eventually look like your usual sunglasses, you will be able to see which are the best restaurants around along with customer reviews and comments. Not only that you can as well be able to check for reservation or even book a table as you check. Sky is the limit.
Types of Augmented Reality
Augmented Reality can be classified based on usage and type of application.
- Marker Based AR – alternatively known as Image Recognition. It uses a camera to see and recognize images or objects and on successful detection , render 2D/3D content over the them.
- Marker-less AR– uses a GPS, velocity meter or digital compass to provide information. A camera may still be used to superimpose digital content on real-world.
- Projection Based AR – This is an advanced way of implementing Augmented reality digital content is dorectly projected onto real world instead of using a middle-ware such as smart phone or PC.
- Superimposition Based AR – This is the most advanced type of Ar where the digital content completely replaces the actual view of the object . It also uses image recognition with more advanced image processing logic alongwith support from other depth sensors.
