It is a live direct or indirect view which turns the environment into a digital interface through positioning objects in in real-time, in the real world. It can be viewed through a wide range of experiences. Augmented reality allows viewers to position 3D models which are life-sized in the environment with or without the use of trackers. Trackers are regular images which 3D models can be attached to in this reality. How augmented reality works is important to understand. The simplest method of tracking is when you use GPS system to automatically your positioning, which is ideal when gathering information about the location you are heading to.

There are two different types of tracking which answer the question how does augmented reality works. Marker less tracking and Marker-based tracking are some examples that you should know. In the first one, you could direct your phone at each image and get a feature -detection or pattern type recognition system to recognize it. This is how our perceptual systems function, as our eyes observe things then our brains fathom what we are viewing, and refer to background information. Our brains are remarkably efficient at this and makes it look simple but it’s a difficult task for computers to tackle this. While in marker-based tracking, an easier selection would be for the museum or gallery to print little, 2-D barcodes next to each item on the display. You direct the camera on your phone to one of the images on display, then your phone would turn the barcode into a web address and its browser would call up an appropriate web page with full information. This enriches your camera display with appropriate information.
Moreover, there are two more ways that explain how augmented reality works which are the projection-based augmented reality and superimposition-based reality. In the projection based, this works through projecting artificial light onto real-world surfaces. This allows for human interaction through sending light onto the real-world surface then sensing the human interaction through touch of the projected light. Sensing the user’s touch is accomplished through knowing the difference between a known projection and the user’s touch. Another application of this is through laser plasma technology which projects 3-D interactive hologram into mid-air. However, superimposition-based, replaces the original view of an object with a new augmented view of that same object. The object recognition plays an essential part because the application cannot replace the original view with the an augmented one if it is unable to establish what the object is.
