In the world of Web3 there are many terms with which we started interacting, such as blockchain, cryptocurrencies. There are some that we have known for a long time, but that still create a lot of confusion. We’re talking virtual reality and augmented reality.

Let’s start from the definitions of augmented and virtual reality

In general, virtual reality (VR) creates an artificial environment that can be explored and interacted with via a VR device, while augmented reality (AR) overlays virtual elements to a real environment via a screen or AR device.

In detail for VR, the devices used, such as VR headsets, PCs or game consoles for interaction controllers and sensors, create an immersive experience for the user, who can "enter" an artificial world and interact with it. Virtual reality is used in many industries, including games, entertainment, education, medicine, and military.

Users of AR, however, can access it via a device such as a smartphone or tablet with a camera and an internet connection. In addition, a specific AR app is required to perform real-world overlapping of digital elements. It creates a hybrid experience between the real world and the digital world. Augmented reality is used in many practical applications, including product design, training, and games.

In summary, virtual reality creates an entirely digital artificial world that can be explored and interacted through a VR device, while augmented reality overlays digital elements in a real environment. Both technologies offer new opportunities for learning, communication and productivity in many industries.

The main uses of VR and AR

Virtual Reality (VR):

• Games and entertainment: VR games provide an immersive and immersive gaming experience;
• Training: VR is used for distance learning in many industries, such as aviation, medicine and the military;
• Medicine: VR is used for rehabilitation and therapy, as well as for the simulation of surgical interventions;
• Marketing and advertising: Companies can use VR to create engaging and engaging advertising campaigns;
• Architecture and design: VR is used for the design of buildings and products, allowing users to view the final result before construction.

Augmented Reality (AR):

• E-commerce: companies can use AR to show how a product will adapt to a real environment;
• Training: AR is used for distance learning, allowing users to view digital elements superimposed on a real environment;
• Marketing and Advertising: Companies can use AR to create engaging and interactive advertising campaigns;
• Games and entertainment: AR games provide an immersive gaming experience that combines the real and digital worlds;
• Technical Support: AR is used to provide remote technical support, overlaying digital elements in a real-world environment to help in troubleshooting.

The future of the two technologies

Augmented reality and virtual reality are currently experiencing a period of growth and development. AR is becoming increasingly popular for use in shopping, gaming, and marketing apps, while VR is used for gaming, entertainment, and professional training.

In the future, AR and VR are expected to have a significant impact on many sectors, such as medicine, education, design, tourism and industrial production. For example, AR could be used to provide interactive real-time instructions when repairing equipment. VR could be used to simulate training and training experiences and environments.

Both offer unlimited opportunities for innovation and the creation of new experiences, making technology an important part of the future of everyday life and work.
