What is augmented and virtual reality? State its advantages and limitations.

Augmented reality and virtual reality (commonly abbreviated as AR and VR respectively) are reality technologies that either enhance or replace a real-life environment with a simulated one. Augmented reality (AR) augments your surroundings by adding digital elements to a live view, often by using the camera on a smartphone.

Virtual reality (VR) is a completely immersive experience that replaces a real-life environment with a simulated one. In AR, a virtual environment is designed to coexist with the real environment, with the goal of being informative and providing additional data about the real world, which a user can access without having to do a search. For example, industrial AR apps could offer instant troubleshooting information when a handset is aimed at a piece of failing equipment.

Virtual reality encompasses a complete environmental simulation that replaces the user’s world with an entirely virtual world. Because these virtual environments are entirely fabricated, they are often designed to be larger than life. For example, VR could let a user box with a cartoon version of Mike Tyson in a virtual boxing ring. While both virtual reality and augmented reality are designed to bring a simulated environment to the user, each concept is unique and involves different use cases.

In addition to entertainment scenarios, augmented reality is also increasingly being used by businesses, because of its ability to generate informational overlays that add useful, real-world scenarios. Augmented reality entails abundant – and growing — use cases. Here are some actual applications you can engage with today. Ikea Place is a mobile app that allows you to envision Ikea furniture in your own home, by overlaying a 3D representation of the piece atop a live video stream of your room. You Cam Makeup lets users virtually try on real-life cosmetics via a living selfie.

Repair technicians can don a headset that walks them through the steps of fixing or maintaining a broken piece of equipment, diagramming exactly where each part goes and the order in which to do things. Various sports are relying on augmented reality to provide real-time statistics and improve physical training for athletes. Beyond gaming and other entertainment cases, some business examples of virtual reality include: Architects are using VR to design homes – and let clients “walk through” before the foundation has ever been laid. Automobiles and other vehicles are increasingly being designed in VR. Firefighters, soldiers and other workers in hazardous environments are using VR to train without putting themselves at risk. 

The advantages of Augmented Reality are listed as follows –

. It increases accuracy.

. It offers innovation, continuous improvement, and individualized learning.

. It helps developers to build games that offer real experiences.

. It enhances the knowledge and information of the user.

Disadvantages of Augmented Reality

.The limitations of Augmented Reality are listed as follows –

.Projects based on AR technology are expensive to implement and develop.

.Excessive use of augmented reality technology can lead to eye problems, obesity, etc.

.It can cause mental health issues

Advantages of Virtual Reality

.The benefits of virtual reality are listed as follows –

.It creates an interactive environment.

.It helps us to explore the world by creating a realistic world using computer technology.

.It makes education comfortable and easy.

.It allows users to do an experiment in an artificial environment.

.It increases the work capabilities.

Virtual reality is helpful for medical students to do practice well. It will be helpful for patients, too, as it offers a safe environment to them by which a patient can come into contact with the things they fear. Virtual reality helps to measure the performance of sportsperson and analyze their techniques.

Disadvantages of Virtual Reality 

The limitations of virtual reality are listed as follows – Using VR, people start ignoring the real world. They started living in the virtual world instead of dealing with the issues of the real world.

Training in the virtual environment does not have the same result as training in the actual world. It is not guaranteed that a person has done a task well in the real world if he/she has performed that task well in the virtual world.
