Augmented Reality: Overview, Benefits and Drawbacks

Augmented reality (AR) is a technology that overlays digital content onto the real world, creating a mixed reality experience. AR has the potential to revolutionize how we interact with technology, making it more intuitive and immersive. In this article, we will explore what AR is, how it works, its applications, and its future potential.

What is Augmented Reality?

AR is a technology that enhances the physical world by adding digital elements to it. It differs from virtual reality (VR) in that it doesn’t create a completely new environment but rather adds digital elements to the existing one. AR can be experienced through various devices, such as smartphones, tablets, smart glasses, and headsets.

How Does Augmented Reality Work?

AR works by using a camera to capture the real world and then overlaying digital content onto it. This digital content is usually created using computer-generated imagery (CGI) or real-time video processing. AR can also use sensors, such as GPS, accelerometers, and gyroscopes, to track the user’s position and orientation, allowing for more precise and interactive experiences.

Applications of Augmented Reality

AR has a wide range of applications across various industries, including gaming, entertainment, education, healthcare, and retail. Here are some examples of how AR is being used in these industries:

Gaming and Entertainment

AR is being used to create immersive gaming experiences. Games like Pokemon Go and Harry Potter: Wizards Unite use AR to overlay digital creatures onto the real world, creating a more interactive and engaging experience for players. AR is also being used in the entertainment industry to enhance live events, such as concerts and sports events, by overlaying digital effects onto the real-world environment.


AR is being used to create interactive and engaging educational content. And AR can be used to create 3D models of objects, allowing students to explore them in a more interactive and immersive way. AR can also be used to create interactive textbooks, which allow students to engage with the content in a more dynamic and interactive way.


AR is being used in healthcare to create more accurate and precise medical procedures. AR can be used to overlay medical images onto a patient’s body, allowing doctors to visualize the internal organs and tissues in real-time. It can also be used to train medical professionals, allowing them to practice medical procedures in a more realistic and immersive environment.


AR is being used in retail to create more interactive and engaging shopping experiences. AR can be used to overlay digital content onto products, allowing customers to visualize how they will look in their homes or how they will work. It can also be used to create virtual try-on experiences, allowing customers to see how clothes or makeup will look on them before making a purchase.

AR has the potential to revolutionize how we interact with technology. As AR technology continues to advance, we can expect to see more immersive and interactive experiences. AR could be used to create virtual telepresence, allowing people to interact with each other as if they were in the same physical location. AR could also be used to create more immersive and interactive work environments, allowing remote workers to collaborate and communicate more effectively.

Augmented Reality Vs Virtual Reality

The terms “augmented reality” (AR) and “virtual reality” (VR) are often used interchangeably, but they refer to different types of immersive experiences. AR and VR are two technologies that have emerged in recent years to change the way we interact with digital information and media. While both technologies are designed to provide an immersive experience, they do so in fundamentally different ways.

Virtual Reality (VR) is a technology that creates a fully immersive, digital world that can be explored through the use of a headset. Users are transported to a computer-generated environment that is designed to look and feel real. VR is a completely simulated experience that can be controlled by the user. It is often used in gaming and entertainment industries but has also been adopted for use in healthcare, education, and training.

On the other hand, Augmented Reality (AR) is a technology that superimposes digital information on the real world. AR enhances the user’s experience by overlaying digital information onto real-world objects. It is often used in smartphone apps, like Snapchat filters or Pokemon Go, to create fun and interactive experiences.

The main difference between VR and AR is the level of immersion. VR is a fully immersive experience that is designed to transport the user to a completely different environment. AR, on the other hand, is designed to enhance the real world by adding digital elements to it. While VR is a complete simulation, AR is a hybrid experience that combines the real world with digital information.

Another difference between the two technologies is their hardware requirements. VR requires a headset that covers the user’s eyes and ears to completely immerse them in the digital environment. AR, on the other hand, can be experienced through a smartphone or tablet.

The applications of AR and VR are also different. VR is often used for gaming, simulation training, and virtual tours. It is also being explored as a therapeutic tool for treating anxiety, PTSD, and other mental health conditions. AR, on the other hand, is used for a wide range of applications, from education and training to marketing and advertising.

Drawbacks of Augmented Reality (AR)

despite its numerous benefits, AR also has some drawbacks that are worth considering.

1. Limited Field of View

One of the significant drawbacks of AR is the limited field of view it offers. AR devices typically require users to look through a small screen or headset, which can only display a small portion of the real world. This limited view can create a disjointed and sometimes frustrating experience, particularly when trying to navigate through a space or interact with virtual objects that are not in the user’s immediate view.

2. Distracting and Overwhelming

AR can be a source of distraction, particularly in settings that require focus, such as driving or working. The technology can be overwhelming, with virtual objects overlaying the real world, making it challenging to concentrate on the task at hand. Additionally, the constant stream of information that AR provides can be overwhelming, leading to information overload.

3. Battery Life and Technical Issues

AR devices require a considerable amount of power to operate, which can lead to battery drain and limit the device’s usage time. Technical issues, such as glitches or lag, can also be frustrating, causing the user to lose focus and detracting from the overall experience.

4. Privacy Concerns

AR technology collects and processes personal data, which can be used for targeted advertising or other purposes. This raises concerns about privacy, particularly when it comes to data collection and tracking. Additionally, the use of AR in public spaces can raise concerns about the recording and distribution of personal information.

5. Cost and Accessibility

AR devices can be costly, making them inaccessible to some individuals and businesses. Additionally, the technology may require specialized knowledge and expertise to develop and deploy, limiting its accessibility to those with the necessary skills.

In conclusion, while augmented reality has numerous benefits, it also has some significant drawbacks that are worth considering. Its applications are already widespread, and its future possibilities are virtually limitless. As AR technology continues to advance, we can expect to see more innovative and exciting use cases, providing new and exciting ways to interact with the world around us.
