Image Analysis Of The Development Of VR

Advances in VR technology allow people to create, entertain, work, collaborate and explore in a computer-generated environment in an unprecedented way.


VR technology has been developed for decades, but it has not been until recently that this technology has become a fast-growing market opportunity in the entertainment and business sectors.


Now, outline a hero and place the image in your space. This is Augmented Reality (AR).


After decades of development, AR seems to have swept the world overnight. The wave of Pokemon Go has brought this popular Japanese exchange card game to the streets. Then dozens of games combine this “magic” technology with the real world.


Apple introduced a set of development tools, ARKit, in 2017 that developers can use to create mobile AR content and encourage more companies to build AR experiences on the iOS 11 platform. This is seen as another sign of the rise of AR.


Both Microsoft's HoloLens and Magic Leap's Lightwear enable people to enjoy the holographic experience and become two important products in the field of groundbreaking head-mounted displays.


This is not only entertainment and games, it also means huge business opportunities. IDC researchers predict that global AR and VR product and service spending will surge from $11.4 billion in 2017 to $215 billion in 2021.


In addition to VR and AR, mixed reality (MR) is also rapidly developing. Developers working on MR research are combining the features of VR and AR with the real world to provide a hybrid experience.


Imagine another VR scenario: You can be instantly sent to a beach chair in Hawaii, with sand on your feet and a cocktail in your hand. Instead of going through a long economy class flight experience, it is sent directly to the island. But in reality you are not really there.


In a mixed reality, you can have this experience. For example, to experience Hawaiian beach on a flight to Hawaii: You are seated on a flight to Hawaii. When you are moving, the flight seats are like a squeaky beach chair. The real flight crew brings you a cocktail. Touch the sand on the floor to experience a beach-like feel.


Since then, VR has undergone tremendous changes. Consumer-grade VR head-mounted displays have achieved breakthroughs. Technical breakthroughs in optics, tracking, and GPU performance have also contributed to the development of VR.


VR has a very high demand for graphics processing - 7 times higher than the requirements of computer games. Without a fast-running GPU that quickly renders graphics, people will not be able to enjoy today's VR experience.


Some experts believe that the development of VR technology will surpass the level of human cognition, and within a decade, its performance will achieve a dramatic improvement, reaching 200 times today. At the same time, NVIDIA researchers are working to improve the user experience.


Frames per second: VR requires processing speeds of up to 90 frames per second. Because lower frame rates can cause macroscopic movements that lag, it may make people feel vomiting.


The VR delay refers to the time difference between the start of the action and the visual image presented by the computer. Experts believe that the VR delay rate should be less than 20 milliseconds. NVIDIA VRWorks is a software development kit for VR head-mounted displays and game developers that solves latency issues.


In VR, creating an immersive feeling is very important. The field of view is the perspective that a particular VR head-mounted display can provide. For example, the Oculus Rift head-mounted display can provide a 110 degree viewing angle.
