Augmented Reality or what we often hear as (AR) is a technology that combines two-dimensional or three-dimensional virtual objects into the real world so that they can apply these virtual objects in reality and in real time.

On the other hand, AR is a technology capable of inserting information into the virtual world and displaying it in the real world. AR also requires assistance such as a computer webcam, a camera, and even special glasses.

How augmented reality works

As discussed above, AR can be displayed on various devices such as mobile phones, special glasses, cameras, screens, webcams, and so on. These devices will function as output devices that will display information in the form of videos, images, animations, and 3D models that need to be used.

The workings of augmented reality are as follows:

1. Camera and Sensor

This tool can be used to collect general information data with users and send it for processing. This tool is capable of examining an environment and the acquired data, as well as finding physical items and creating 3D objects.

2. Projection

One should know what AR component projection is. This component refers to small projectors. For example, like a headset, the device will receive information from sensors and project computerized content onto a surface for viewing. However, the actual use of these components is not exactly the same as intended for use on vehicles.

3. Reflection

AR devices in reflection have a mirror to help the human eye see the image virtually. With this method of reflection, some devices have various angled mirrors and some have mirrors in two sides. This serves to reflect light to the camera and the user’s eyes. The purpose of the reflection mode is to play a precise and accurate setting of the image.

Examples of Application of Augmented Reality

  1. Game

Still remember the game pokemon go? Or is anyone still playing?? This game has its own charm because it has the concept of combining the real world with your favorite Pokemon characters. This game makes you feel as if you were in the Pokemon world. Other games that use the AR concept are Harry Potter, Jurassic Park, and many more

  • Social Media

One of the AR features that you often use is on Instagram. Who doesn’t know Instagram filters? Yep, almost everyone can already use filters because of the availability of some interesting and entertaining filters of course. These filters are created using AR as a 3D object and also use a touch of AI (Artificial Intelligence) technology as the logic.

  • Medical

In the world of medical education, augmented reality technology is often used. Both in the form of applications and other operating equipment. At the Cleveland Clinic at Case Western Reserve University, students use AR headsets to learn the intricacies of human anatomy.

  • Broadcast

This is definitely an area that you come across often. From weather broadcasts to sporting events. AR in the form of images on your TV screen is common. If you usually find quality impressions in terms of visual objects, that’s the use of AR technology. An example of a film that uses AR is Star Wars.


Virtual reality or what we often see as (VR) is a technology that can make users interact in a virtual world that is simulated by a computer. As the name implies, this VR user can feel being in the environment the user wants even though he is at home. Virtual reality can be used whenever and as you wish. This is because VR itself has a size that can be carried anywhere.

How virtual reality works

The way VR works begins with the user seeing the desired world through dynamic images generated from computer simulations. then assisted by tools such as VR glasses, users can feel entering a virtual world that does not use the real world at all.

positive impact of VR

  • profession simulation
  • can fill empty time
  • free vacation

negative impact of VR

  • forget the time
  • overly addicted
  • cause disease
