Augmented Reality (AR) is an interactive experience of a real-world environment where the objects that reside in the world are enhanced by computer-generated perceptual information.
There are several types of augmented Reality. However, there are four main types of augmented reality, which are commonly used in daily life.
1. Projection-based Augmented Reality
This type of AR is one of the simplest types of augmented Reality. In this type, the projection of light is focused on a surface. Projection-based AR is interactive and appealing, where they project the light onto the surface. Furthermore, the interaction with the object usually done by touching the projected surface with hands.
Projection-based Augmented Reality usually used to project digital keyboards on your desk’s surface. In some cases, the image produced with projection is non-interactive. These non-interactive projections can be used to create images of objects that you can see in-depth. This type of AR can be used for future settings. For example, if you want to check that your future fridge will fit into that space near the oven, by projecting the non-interactive projection of fridge.
2. Location-based Augmented Reality
Location-based or Marker-less Augmented Reality is one of the most commonly implemented applications in the industries. This technology gets its name due to easily available features in the Smartphones that provide location detection. Location-based applications usually help travelers. If you are a traveler and want to find new great places, this application by accessing the device’s GPS location, gives the relevant information about what you are looking for on your screen. Furthermore, this type of AR technology is all about adding location information on the screen about the objects that can be seen from the Smartphone’s camera. Alter reality games are good examples of location-based augmented reality.
3. Recognition-based Augmented Reality
Recognition-based augmented Reality is also known as marker-based AR. This type of augmented Reality is mainly used to get more information about the object/item after the recognition of that object. This technology is widely used in departmental stores and industries too. Furthermore, whenever you use a QR code or scan an image, and it comes to live, you are actually using marker-based AR.
Another common use of recognition augmented Reality is the translation of words. Recognition augmented technology helps to translate the words seen through the camera of a Smartphone to another language. This type of AR technology is globally used in every field.
The recognition of QR or other code through the scan, this technology replaces the marker on-screen with a detailed 3D version of the object. This technology helps the user to know the object, especially look and specifications in more detail from various angles. In addition, you can also rotate the image view of the object when you rotate the marker to different angles.
4. Superimposition-based Augmented Reality
As the name shows, Superimposition Based Augmented Reality is the replacement view of the objects in focus. This process usually occurs with the partial or entire replacement of the view of an object with an augmented view. Similarly, FPS games are the best example of Superimposition based Augmented Reality. In these games, your soldier has advanced military equipment showing night vision, infrared view, and radioactive view.
