What is Augmented Reality (AR) ?

Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it.

There are three types of AR: 

  • Image target, in which you overlay a real-world 2D image with video, text, images, or 3D objects 
  • Object recognition, in which you fix a digital 3D model to a real-world 3D object 
  • Plane detection, in which you fix a digital 3D model to a real-world flat surface

Advantages of AR Technology

  • Through AR technology users can interact with the real world in real time.
  • AR technology also enhances the perceptive power of humans.
  • AR technology facilitates the users to ubiquitously and timely access to information that is required.
  • It saves the time of users (doctors, surgeons, students etc.) on searching information about a particular topic.
  • AR technology recognizes the user's freehand gestures and saves electricity to a large extent.
  • Due to AR technology, information has become more realistic.

Disadvantages of AR Technology

  • Many of the smartphones do not possess the capability of feeling the external camera in real time.
  • AR technology could lead to people becoming more dependent on devices this may cause a large number of health-related issues.
  • AR technology is not equipped with security policies. Intruders can hack the AR-based devices and can manipulate the devices according to their needs.
  • It is expensive to develop AR based systems and its maintenance is also very expensive.
