1) AR: Augmented Reality (Augmented Reality, AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The virtual world sets and interacts with the real world. This technique was proposed in 1990. With the improvement of CPU computing power of portable electronic products, it is expected that the use of augmented reality will become more and more extensive.
AR systems have three prominent features:
① Real-world and virtual information integration;
②It has real-time interactivity;
③ is to add positioning virtual objects in the three-dimensional scale space; AR technology can be widely used in many fields.
2) VR: is the abbreviation of Virtual Reality, which means in ChineseVirtual Reality, earlier translated as "Spirituality Technology”. Virtual reality is the ultimate application form of multimedia technology. It is the crystallization of the rapid development of scientific fields such as computer software and hardware technology, sensor technology, robotics, artificial intelligence and behavioral psychology. It mainly relies on three-dimensional real-time graphic display, three-dimensional positioning Tracking, tactile and olfactory sensing technologies,artificial intelligenceThe development of many key technologies such as technology, high-speed computing and parallel computing technology, and human behavior research. With the development of virtual reality technology, the real realization of virtual reality will cause great changes in the whole human life and development. people wearstereo glasses、data glovesFaced with a three-dimensional simulated reality, it seems to be in a sensory world with three-dimensional vision, hearing, touch and even smell, and people can interact with this environment through their natural skills and corresponding facilities. Information exchange.
ARDifference from VR
VR is virtual realityVRWhat means? What is the use of VR”, let’s talk about the difference between AR and VR.
VR (the scene is fake, but it looks like reality)
From several aspects, first of all, what VR wants to bring to users is immersion; AR is to combine virtuality with reality and get rid of immersion. Then, on hardware devices, VR devices focus on closed immersion, which can make people feel immersive, and its content is virtual.
AR devices focus on helping life and work. At present, low-end AR devices can use smartphones, and high-end devices can use smart glasses. The smart hardware devices we are talking about now refer to smart glasses. There are already many smart glasses. Microsoft Hololens , Realmax, Meta, Epson bt200, MBT2000. These are the smart glasses that can be seen on the market at present. Among them, the price of Hololens is too high, 3,000 US dollars, and the cost performance is too low, which is unacceptable for ordinary users; the smart glasses from Realmax are priced at around 8k, and they are suitable for both life and industry. In terms of appearance, it is similar to ordinary glasses. It will take a few more years for smart glasses to replace mobile phones and computers in life, but the products that have come out now are enough to be used in some industries.
VR is all fake, fake scenes, fake elements, everything is computer made. AR is half-truth and half-truth. For example, using a mobile phone lens to watch a real scene, when you see a real element, trigger a program to enhance the experience. For example, when you see a poster, you suddenly find that the person on the poster is walking down. . AR can be seen as a half-truth, immersive experience that mixes real scenes and virtual reality. VR is all about immersive virtual scenes. Since AR and VR devices have not yet become popular, I believe that after the user experience in the future, there will be a clearer understanding of the difference between the two.
