Computer Vision in the Metaverse


Computer Vision in the Metaverse

The word Metaverse is a combination of the prefix meta (implying transcendence) and the word universe and refers to a hypothetical synthetic environment. Defining some terms will be useful before we examine computer vision in the Metaverse. First let’s examine the concepts of Extended Reality (XR), Mixed Reality (MR), Augmented Reality (AR), and Virtual Reality (VR). Then we can discuss computer vision’s role in the Metaverse

Extended, Mixed, Augmented, and Virtual Reality

Wearable devices create real and virtual environments through Extended Reality (XR), also known as human-machine interactions. By combining the virtual and the real worlds, Mixed Reality (MR) makes it possible for digital and physical objects to interact in real time. Mixed Reality (MR) is a hybrid of two realities, not two coexisting realities. Augmented Reality (AR) is a technology that enhances users’ visual fields with necessary information. Virtual Reality (VR) allows users to experience the world from an entirely virtual perspective, with no connection between them and the real world. With Virtual Reality (VR), users can enter a three-dimensional (3D) virtual world using a computer.

The Advantages of using Computer Vision in the Metaverse

Computer vision plays an essential role in allowing humans to interact with virtual environments in the Metaverse. Virtual reality and computer vision avatars provide almost real-world experiences. It is possible to create this virtual world using extended reality products, but extended reality relies on computer vision. The role of computer vision in XR applications cannot be overstated. In order to make meaningful decisions and take action, visual information and computer vision are crucial for processing, analyzing, and understanding digital images and videos. By analyzing visual data from users’ activities and physical surroundings, XR devices can build more reliable and accurate virtual and augmented environments. In an interactive environment, human pose estimation and tracking involve obtaining spatial information about human bodies using computer vision. 3D environments are recreated by computer vision in XR applications. The XR device determines the direction and location of the user. It is necessary for XR interactive systems to track the body and pose of users. In the Metaverse, users will be tracked by computer vision and represented as avatars. Metaverse also requires users to perceive their surroundings. Therefore, image processing plays a crucial role in developing a better metaverse. Metaverses and physical environments are seamlessly connected in real-time. Thus an avatar should be able to interact with a real person. The metaverse must display the 3D virtual world with less noise, blur, and high resolution. Metaverse interactive systems still need to show the virtual universe under adverse visual conditions, such as haze, low or high brightness, or even rain.

The Disadvantages of using Computer Vision in the Metaverse

A major disadvantage of using computer vision in the Metaverse is its inability to access a fast and secure internet source and the difficulty involved in making extended reality (XR) accessible to everyone. It may not be feasible to create a vast virtual universe in the near future with a suitable  user experience. In addition, as the number of users increases, these technologies have to remain current, smooth, and high-performing.

Application Computer Vision in the Metaverse

The metaverse includes domains such as healthcare, real estate, manufacturing, education, and retail. Metaverse Health apps can speed up surgical procedures, examine data obtained from 3D scans in real-time, help patients detect, diagnose, and treat possible diseases, and let them see their own bodies. Metaverse is likely to play a significant role in our lives in the future. And many are investing in it accordingly. Despite the efforts in today’s business world to adapt quickly, it is predicted that many sectors will be impacted by the Metaverse in the future. Computer vision will be one of the main tools used to develop augmented reality (AR) and extended reality (XR) products, or new products will emerge.

Metaverse Real Estate Applications

Virtual reality tours allow real estate marketers to review properties before making any selections for their clients. Customers can also  examine properties to save time and eliminate unnecessary travel.

Metaverse Production Applications

The use of virtual reality applications in factories significantly reduces the risk of accidents. Using augmented reality simulations, new employees can be trained quickly and safely without having to spend time and money on training.

Metaverse Educational Applications

Students prefer watching over reading. It’s much easier to teach concepts visually than to use traditional approaches. That’s why virtual reality can be an effective tool to teach various subjects
