Learn what is one of the techniques of metaverse

A few years ago, advances in augmented reality (AR) took over the tech world with the advent of applications capable of fusing virtual content with real-world imagery. With the recent popularity of the concept of Metaverse (immersive virtual environments), this innovative proposal has a resurgence along with virtual reality, 5G and holograms.

Software engineer Mateus Bueno stressed that the secret to making virtual worlds useful in the current market is through AR applications. For him, the technology will be able to give more practical and understandable meaning to the immersive experience of the new system, which will attract more people.

“Augmented reality is the most attractive area of ​​the metaverse in the short and medium term because it’s easier [e barato] Users access virtual content integrated into the real world than relying on virtual reality devices [que são mais caros]”,He says.

Additionally, today’s smartphone cameras provide easy access to AR experiences. To experience a virtual reality environment, you need to buy the right glasses – which requires more investment.

For example, there are already platforms used today to create AR experiences on mobile phones and internet browsers. It is expected that in the near future, new hardware and software should also be able to meet these needs.

“At the moment, we always have our heads down and staring at our phones. With augmented reality, we will see the real world again, but with digital elements, the information can be useful and interesting. We will look up again”, AR company Magic Leap Peggy Johnson, president of the Metaverse, said of the true value of the Metaverse.

How Augmented Reality Works

Álvaro José Rodrigues de Lima, professor at the Department of Representation Technology at UFRJ (Federal University of Rio de Janeiro), explained that when we film a location in real time and insert virtual objects and the resulting scene, we have an augmented reality environment that gives the impression that virtual objects belong to the real world impression.

Professor Romero Tori of Centro Universitário Senac added: “That old amusement park attraction, where a woman turns into a gorilla, will be an augmented reality without the use of sophisticated technology.”

Today, augmented reality comes in four main forms.

  1. The camera captures the real world, and the software includes virtual elements on top of the video.
  2. After installing virtual reality glasses and cameras, users can see the environment in front of them through virtual elements.
  3. Glasses with translucent lenses blend the environment with the image.
  4. Video mapping technology projects images onto building facades.

Which sectors should make better use of AR?

entertainment: This technology has been widely used in games. There are also apps that overlay information on artwork and manipulate virtual research objects as if they were on a table.

healthy: Convenient for surgery. Before a doctor begins an operation, he can use AR to plan a patient’s intervention.

Fashion: Companies like Nike and Amazon are also using immersive tools like avatars to sell clothes and shoes.

Hydrology, Ecology and Geology: Displays specific and detailed information about the terrain or 3D map.

Augmented reality challenge

Companies and researchers have been working to develop more applications in the field, but some experts believe it shouldn’t catch on so quickly, even if it has the potential to change our relationship with technology.

“Using augmented reality can be very difficult because the device [dispositivo] You basically need to trick his eyes: show him something that’s not in that space. You have to put digital content into space, and it’s a huge optical challenge that can’t be solved magically, so much that we’ve been in the business for 10 years,” said Magic Leap president.

Here are some examples of applications for augmented reality:

Flightradar24 (iOS, Android)

The purpose of this app is to identify and provide data about aircraft passing in the sky at the time. To do this, just point your phone camera at it.

Ingress Prime (iOS, Android)

Produced by the same Niantic who created “Pokémon Go,” Ingress Prime is a sci-fi game where you’ll take part in an episode about mystical energy and the portals it opens in our world. With GPS turned on, the game recognizes the street you are on and shows you exactly where the portal opens; you have to go there to fight the energy.

Wikiitude (iOS, Android)

Wikitude allows you to scan images in magazines created specifically for the application and display additional multimedia resources such as photos, text and videos. Used on the street, it also adds extra information about public spaces.

Toy Car Remote Control (iOS, Android)

This one is simple and efficient: download the app on your phone, print or download the bookmarked image on another device, and place the cart on top of the bookmarked image. You can drive it around the room or through a virtual scene. Great for kids.

Enhanced (iOS, Android)

With Augment, you can place 3D models of different applications in the real world. You can change the position, rotate and even change the size. If a furniture store offers a chair model through the app, you can see how it will look in your living room before actually buying it.

Skyview - Disclosure - Disclosure

Sky View (iOS, Android)

Astronomy apps are more common, and they use the phone’s motion sensor to show the position of each star in the sky. What makes Skyview different is that it turns on the camera and blends your environment with constellation images, day or night.

Zookazam (iOS, Android)

Combine images printed on paper or on a computer screen to create educational applications for 3D animals and objects. For example, it is more useful for children to learn what a shark looks like without touching it.

Anatomy 4D - Disclosure - Disclosure

Anatomy 4D (iOS, Android)

Another is learning oriented. Print or download these images to your tablet to use as bookmarks. From there, through the app, you can get a 3D model of the human body and divide it into all systems: circulatory system, muscular system, skeletal system, etc. There’s even a specific model of the human heart.
