A few days ago, Facebook CEO Mark Zuckerberg testified in court to deny the company’s Oculus department’s allegations of plagiarizing virtual reality technology. Because of this incident, people began to pay more attention to virtual reality technology, and AR and VR are even more crowded.
In response to the plagiarism prosecution, Facebook CEO Zuckerberg answered questions in court about the source of Oculus's ideas and whether he had enough knowledge of Oculus at the time of the acquisition.
ZeniMax Media (hereafter referred to as "ZeniMax") sued Oculus in 2014, when Facebook was acquiring the latter. ZeniMax claims that Oculus illegally uses its intellectual property to develop virtual reality systems, including Rift heads. And said that when Facebook acquired Oculus, its virtual reality technology is still not mature.
Accepting ZeniMax lawyer Tony Sami "Improving technology doesn't mean technology is yours. Stealing my bike, brushing paint, getting a bell, the bike is yours?" Zuckerberg replied "No, but Oculus's idea of ​​developing his technology based on other company ideas is wrong."
From this war of words, we can see that virtual reality is an important part of Facebook's future business, especially in the context of the technology's increasingly low price and increasingly clear use. In addition to Facebook, domestic Alibaba, Baidu, Tencent and other Internet companies are also investing a large amount of money to develop virtual reality technology.
This shows that virtual reality technology will be the most competitive sector in the Internet industry in the future.
1. What kind of ghost is VR?
Baidu Encyclopedia's explanation is that VR (Virtual Reality) is virtual reality, which was proposed by American VPL founder Lanier in the early 1980s. The specific connotation is: comprehensive use of computer graphics systems and various display and control interface devices to provide immersive sensation technology in a three-dimensional environment that can be generated on a computer.
2. What does AR look like?
AR is to put the computer-generated virtual world in the real world, that is, to add the digital imagination world to the real world. Objects in front of the user will be changed by the AR through the phone lens, special glasses or helmet. With AR, users will always be able to see what's in front of them, but with a layer of virtual elements superimposed on them.
The difference is that the VR virtual reality scene is interactive rather than unidirectional; AR is augmented reality, that is, the real world experience is enhanced by the device, the user is in the real world, and the observed content is superimposed on reality. Above the world.
From the point of view of the device, the VR device is usually "cumbersome" and has the following characteristics: it needs to be covered like a helmet on the head; it is completely enclosed, and there are rubber or sponge products in contact with the face to make the face and the device closely fit to prevent Light leakage; the eye lens is usually a circular convex lens.
AR devices are usually presented in the form of glasses. For example, Google glass, the eye lens is usually a square prism. After the user wears the AR glasses, the image is projected on the prism through the micro projector in the frame, and then reflected by the prism to the human eye. Through the prism, the eye sees the display superimposed on the real scene.
How important is virtual reality technology to the Internet industry?
In terms of development direction, mobile VR is the trend of the times. Products like HTC and Sony are virtual reality devices based on PCs or game consoles. The advantage of this device is better performance. The disadvantage is that the cost is very expensive and lacks portability. There are many domestic products and more affordable prices, which can cover more users. Although the experience of mobile virtual reality is worse, with the advancement of technology, this gap will become smaller and smaller, and mobile virtual reality will affect people more. life.
In addition, virtual reality can improve the user's perception from the technical level; the interaction allows the user to “communicate†with the created virtual space. This “communication†includes not only the input and output of information, but also how to interact with virtual reality and other Users interact; imagination refers to how to create a more interesting space.
High-speed Conductive Slip Ring, the speed is required to be at least tens of thousands of revolutions per minute, the structure of conductive slip ring directly determines the contact of high speed, as well as the size of impedance. High speed slip ring materials have high wear resistance, high life characteristics, multi-contact contact can ensure signal transmission and power reliability, with the development of science and technology, high-speed slip ring will be more and more widely used.
