What Is Augmented Reality?

2 min read

The word Augmented means to add or to enhance. Hence, Augmented reality, which is called Virtual reality means to add in the reality a range of data such as images, animations, videos or 3D models, enhancing the user’s experience. Thus, it combines real and computer-based scenarios and images to create an enhanced view of the world for the user. The main aim is to deliver imaginative elements which don’t exist in the real world. Through this, a rich audiovisual experience is created implementing different models and applications.

It all began in the 1960s, when Ivan Sutherland and Bob Sproull created a rough device that displayed primitive computer graphic, called The Sword of Damocles. Today with the advancement in technology, there are 4 types of augmented reality:

Markerless AR

The markerless augmented reality is also called the location-based AR, position-based AR or simply, the GPS. The techniques used here, such as GPS, velocity, digital compass or accelerometer are placed in the device for tracking purpose. It is basically a location detection feature which helps gather data related to the tracking of the location. The implementations of the markerless AR are to find nearby petrol pumps, restaurants or other businesses, mapping directions and other features like sending your live location to a friend.

Marker-based AR

A marker-based augmented reality, which is also called image recognition uses visual marker techniques. These techniques include camera, or QR/ 2D code to produce the augmented reality and to distinguish a marker from any other real-world element. These markers can be read in the forms of a QR code or image, to make the reading simple. The implementations of marker-based AR in today’s world uses sensors in devices which accurately detect the real-world environment, such as displaying 3d model in Web Cam Texture in real-time, allowing the users to see virtual objects in reality without the need of reading an image.

Projection based AR

A project based augmented reality allows sending light for human interaction in reality. Hence, artificial light is projected onto real life surfaces using the technique- projection mapping. Systems and elements such as visible light cameras and 3D sensing systems such as a depth camera are used to support the technique. Together, this allows any digital display to appear upon a real-world surface or object. This is different from other AR types since it allows sharing the experience created by augmented reality in the physical world.

Superimposition based AR

A superimposition based AR allows replacing the original view of an object with an augmented or an artificial view of the same object. It is an important and useful technology, mostly used in the medical and military field.  X-rays are a successful and widely recognized example of the superimposition based augmented reality. This means the AR techniques are not just limited to your smartphones and video games, but also have entered clinics and schools for a better learning and treatment experience.

Advantages Of Augmented Reality

Let’s study how augmented reality technology is making our lives better:

  1. Improves Safety

    With technologies used in augmented reality, situational awareness can be improved. Hazardous situations can be avoided by sending information such as environmental changes and temperature differentials. AR not only works for climatic conditions but for indoor security as well. Sound for warning signal, providing indoor GPS and sharing location information to the central location are a few things which are possible through AR.

  2. Interactive Experience

    AR is a big helping hand to curate advertising strategies and games which allow users to experience a more interactive and personal experience. It not only activates the IQ but also, the EQ i.e. Emotional Quotient. The objects using the AR technology build a deep connection with the user. These sensory driven techniques also help in creating a rich environment for the user. Also, increases the knowledge assimilation and retention power by making things more engaging and exciting through the practical approach.

  3. Creating Imaginative Scenarios

    Augmented and Virtual technologies have been successful in creating scenarios that are otherwise impossible to create. They have enabled organizations and institutes to create an environment which is impossible to create in reality due to factors like cost and lack of resources. Basically, it creates another world for a better experience and high learning of something. It also increases the practicality among businessmen, employees and students.

The above information was a brief about Augmented or Virtual reality and how is it improving our daily lives. With upcoming models and projects by organizations like Apple and Google, the AR technology will get more advanced. It is also been predicted by analysts that the AR market will grow to more than $100-130 billion by the year 2020. Hence, a great potential has been seen in this technology and its presence shall be seen in various sectors and markets in the coming years.
