Advances in Augmented Reality (AR) have taken over the world of technology a few years ago, with the creation of applications that combine virtual content with real-world imagery. With the recent rise of the idea of the metaberse (immersed in the virtual environment), this proposal for innovation is on the rise again, along with virtual reality, 5G and holograms.
And the secret of the current market to make metaverse useful is through AR applications, said software engineer Mateus Bueno. For him, this technology will be able to give a more practical and accessible meaning to the immersive experiences of new systems, involving more people.
“Augmented reality is the area of metabersion with the highest traction capacity in the short and medium term, as it is easier. [e barato] rather than relying on virtual reality devices for users to access integrated content in the real world [que são mais caros]”He said.
In addition, AR experiences can be easily accessed by today’s telephone cameras. In order to live in a virtual reality environment, it is necessary to get the right glasses, which requires more investment.
Today, for example, there are already platforms in place to create AR experiences, both on mobile phones and on Internet browsers. It is anticipated that in the near future, new hardware and software will also need to meet these requirements.
“At the moment, we’re always looking down on cell phones. With augmented reality, we’re going to see the real world again, but with the elements of digital, with information that can be useful and interesting. We’re going to look up again,” said Peggy Johnson, president of Magic Leap AR. about the true value of the metaverse.
How augmented reality works
Álvaro José Rodrigues de Lima, Professor of Representation Techniques at the UFRJ (Federal University of Rio de Janeiro), explains that we have an augmented reality environment when we shoot a location, in real time, and insert virtual objects and formed scenes. to represent that virtual objects belong to the real world.
“This old amusement park, where a woman becomes a gorilla, would be a kind of augmented reality without the use of sophisticated technology,” added Professor Romero Tori of the Centro Universitário Senac.
Today, there are four main forms of augmented reality.
- The camera captures the real world, and the software captures virtual elements on top of the video.
- By attaching virtual reality glasses and cameras, the user sees the environment moving forward with virtual elements.
- Glasses with semi-transparent lenses blend the environment with images.
- Video mapping techniques project images onto building facades.
Which sectors should better exploit AR?
Entertainment: technology has been widely used in gaming. There are also applications that overlay information on artwork, and there is also the ability to manipulate virtual learning objects as if they were on the table.
health: to facilitate surgical procedures. Before the doctor can begin the procedure, he or she can use the AR to determine how the patient will respond.
Fashion: Companies like Nike and Amazon are also moving forward and selling clothes and shoes using immersive tools like avatars.
Hydrology, ecology and geology: Show accurate and detailed information about the territory or three-dimensional maps.
Companies and researchers have been working to develop more applications in this area, but some experts believe that it should not be so quickly recognized, even if it has the potential to transform our relationship with technology.
“Working with augmented reality can be very difficult because of the device [dispositivo] basically, you have to deceive the eyes: show them something that is not in that space. You just have to be more discriminating with the help you render toward other people.
Here are some examples of applications that work with augmented reality:
Flightradar24 (iOS, Android)
The purpose of this application is to identify and retrieve data about aircraft currently passing through the sky. All you have to do is point your camera at your mobile phone.
Ingress Prime (iOS, Android)
Produced by Niantic himself who created “Pokémon Go”, Ingress Prime is a sci-fi game in which you take part in an argument about an energy and a mysterious portal that is opening up in our world. With the GPS turned on, the game recognizes the streets where you are and shows the exact points where the portals open; you have to go there and fight the energy sources.
Wikiitude (iOS, Android)
Wikimedia allows you to scan images from magazines created specifically for the application and show more multimedia resources, such as photos, text, and video. Using it on the street also adds additional information about public places.
Toy Car RC (iOS, Android)
This is simple and effective: Download the app to your mobile phone, print or download a bookmark image here on another device, and then drop the cart over the bookmark image. You can drive around the room as well as in virtual sets. Great for kids.
Enlarge (iOS, Android)
With Augment you can place 3D models of different applications in the real world. You can resize, rotate, and resize. If a furniture store offers a model of a chair through the app system, you can see what it will look like in your living room before you actually buy it.
Skyview (iOS, Android)
Astronomical applications are fairly common, and they use mobile motion sensors to show where each star in the sky is. The difference with Skyview is that it opens the camera and blends your surroundings with images of the constellations, day and night.
Zookazam (iOS, Android)
An educational application that creates 3D animals and objects in combination with images printed on paper or a computer screen. Without touching the appearance of a shark without touching it, for example, it is more useful for children.
4D Anatomy (iOS, Android)
Another aimed at learning. Print or download these images for use with your tablet as a bookmark. From there, with the app, you can get 3D shapes of the human body and split it into all its systems: circulatory, muscle, bone, etc. There is also a specific pattern of the human heart.
