Augmented Reality (AR) Definition
Augmented Reality (AR) is a technology that overlays digital or computer-generated data—such as videos, graphics, sounds—onto the physical world, thereby enhancing the user’s perception and interaction with the real-world environment.
Augmented Reality (AR) Key Points
- AR integrates digital information with the real world in real time.
- Unlike virtual reality, which creates a wholly artificial environment, AR uses the existing environment and overlays new information on top of it.
- AR changes the way we view the world, enhancing the physical world with computer-generated perceptual information.
- AR can be experienced through devices like glasses, screens, handheld devices, mobile phones, head-mounted displays.
What is Augmented Reality?
Augmented Reality is a technology that expands our physical world by adding layers of digital information onto it. Rather than replacing the real world, as in Virtual Reality, AR appears in direct view of an existing environment. AR adds sounds, videos, graphics to the natural world as it exists, creating an enhanced user experience.
Why is Augmented Reality significant?
AR is significant because it brings elements of the digital world into a person’s perception of the real world, thus enhancing the perception of reality. This not only changes how we see the world, but also increases efficiency and effectiveness in our everyday tasks. In the context of blockchain and cryptocurrencies, AR could potentially visualize blockchain transactions, or create immersive and interactive experiences around cryptocurrency market trends.
Where can Augmented Reality be used?
AR can be used in multiple sectors such as gaming, education, medicine, engineering, and retail among others. For instance, it can be used to overlay helpful information in real-time situations, like providing directions in real-time during travel, annotating an assembly procedure in a factory, or providing patient data insights to a surgeon during a surgical procedure.
When did Augmented Reality start to emerge?
The concept of Augmented Reality started to emerge in the late 20th century. However, due to technological constraints, it didn’t become popular until the 21st century. The release of AR mobile games and AR filters on social media platforms further popularise the technology in daily life.
How does Augmented Reality work?
AR works by utilizing computer vision, along with depth detection and other technologies to modify the user’s perception of reality. This might involve superimposing images over what the user sees, or projecting light into the user’s eyes to create a digital image on their retina. In most cases, AR experiences are initiated by users through apps installed on their smartphones or tablets.
