VR is cool and powerful? AR may be more powerful than its cost

Tencent digital news (chares) What is AR? This technology was planned long ago many years ago. In fact, it has only recently been widely developed. Thanks to the powerful hardware and software of smart phones, AR can be easily put into your pocket. After downloading the app, you can quickly open your eyes. can use.

So what is the difference between it and VR? In fact, the two technologies are very different. VR can connect smart mobile devices. Through various sensors, you can completely immerse yourself in the virtual world without being bothered by the outside. AR in the real world presents a virtual 3D image of the object. When you perceive a virtual object, you can also perceive the surrounding environment. Besides VR and AR, there is another technology called MR. It is a technology between VR and AR called mediating reality technology. The full name of Mediated Reality (referred to as MR). VR is a pure virtual digital picture, Mixed Reality including AR is a virtual digital picture + naked eye reality, and MR is a digital reality + virtual digital picture.

Like movie iron man, using VR can interact with virtual objects in front of it. In movies, this is CG special effects. In reality, he is a real AR. With the improvement and development of technology, the complex design behind AR. It has become more and more simplified. Perhaps in the near future, we can use this technology to completely lose the smart phones and bulky head-mounted display.

The AR equipment that the world really meant was born in the 1960s. It was designed by Ivan Sutherland of Harvard University. It was called “Sword of Damocles” and Ivan used AR to superimpose the virtual grid of geometric grids in the visual window. Graphics, the device was awkward and impractical at the time, this is the prototype of AR, but at least the surface of some of the problems that computer science can handle AR can also be processed, and then AR research continued into the 90s, until then, AR Only groundbreaking developments have been applied to the Army and NASA's space programs. At the time, the phones were not enough to drive the AR, but they could be used to scan QR codes.

After 2000, the German researchers Daniel Wagner and Dieter Schmalstieg (now considered the real pioneers of AR) for the first time built a framework for running AR on mobile devices. Later, these smartphone devices received a lot of hardware and software. In the development, AR became a novelty device that combined these smart products. Osterhout R&D team CEO and founder Ralph Osterhout saw the great potential of AR since then. He said: “The iPhone released by Apple in 2007 can be called The first truly smart phones in history are more data-driven than simple ones. Nokia did well in the consumer market at that time, but producing a smart phone required many complicated parts, such as processors. , memory and other hardware, if you want to enter the market, you must reduce the cost of these hardware costs, 8 years ago, 4GB of memory is very expensive, especially the dual-core processor, to be placed in the present, to purchase these parts The money is enough to buy a complete product. With the same reasons as the cost, AR will not be mature enough to achieve mass production.

In 2014, Google Glass took to the stage and once again AR attracted people's attention. However, as Osterhout pointed out, the cost price of AR is still too high. Later, people generally reacted to the glass characteristics of Google Glasses and made people uncomfortable. There was a fever wave in AR. It quickly retired. A year ago, Microsoft launched HoloLens holographic glasses. Like Meta, Epson and ODG also began to independently develop their own hardware, Magic Leap is one of them, this mysterious and low-key AR company once invested 91 Billion RMB to develop an Augmented Reality platform similar to Microsoft's HoloLens, claiming that holographic projection can be viewed and interacted with without the need for additional equipment such as glasses, and the content can be directly projected onto the retina without a screen. So far, no one knows Magic. As for the Leap equipment, Magic Leap did not publish any pictures.

Using AR as a game, this idea seems to be good. Microsoft HoloLens tried to attract users through "My World", but the price of 20,000 is really chilling, and now with Pokémon Go becoming more and more popular, from the data, The use of AR to capture the elves has indeed attracted many people's attention. The combination of smart mobile devices and AR seems promising, said Nima Shams, vice president of ODG. "AR has great potential. With the improvement of technology, AR's development space It's still big.” Soren Harner, chief product manager at Meta, said that Pokémon Go’s game has done a good job of promoting the AR, which will drive more people to buy AR later.

What is the future of AR? It may take some patience to succeed. Its corresponding product, VR, has gradually penetrated into every aspect of people's daily life. Of course, there are many areas that need improvement. Pokémon Go-like games also paved the way for the development of AR. The cost of hardware is reduced to a reasonable position and having a pair of Google glasses should not be a problem. AR also needs improvement in technology, sensors, visual tracking, change effects and interactive functions must be smooth and coherent. AR also needs to be lighter, not limited by the environment, and allows you to use it to meet all daily activities.

The AR should have more practical functions. For example, before you travel, you can see various sights of the sights through AR. Before buying furniture, you can see through the AR whether the furniture in the living room is beautiful or not. Within three years, through smart glasses and AR, this technology may formally enter the consumer market. Improvements in design, comfort, and fashion will have a revolutionary impact on our daily lives. However, AR still needs to be preserved. On the mobile device platform, this requires that the user's smart phones can all support access to AR equipment. Through various APPs, AR equipment can handle various tasks. Pokémon Go is just the beginning of AR. It also indicates the future development. Afterwards, the usefulness of AR smart glasses will be even greater than that of VR. AR has many functions that smart phones cannot match. Therefore, mobile phones may not be the best intelligent platform for media products and information exchange.

Meta thinks that their heads will become the computer screen of the future in the short term, and AR will become a new interface, completely replacing the display, but creating such a new access method is not a trivial matter if you leave the mouse and Keyboard, how does the user interact with the real world? We see that many R&D programs have been introduced successively, such as eye tracking, physical interactions, voice control, etc. Perhaps the best choice is integration.

Meta company said that in order to cooperate with VR development, they launched 16 to 20 APPs, many of which are related to education and learning. Meta employee Harner said: “Using VR, we can use remote assistants to visualize 3D images to help learning and education. Creating immersive effects will make students more attractive and more efficient in class. Not too many children’s computer technology is already integrated with students’ classrooms, and AR technology is the same. We believe that by projecting virtual images into reality The world will greatly enhance classroom interaction and interest. Teachers can use this technology to teach anatomy, chemical reactions and even build virtual solar system space models in astronomical classes. These are huge applications in the field of education.”

Similarly, NuEyes and Vital, which are owned by the Osterhout Group, have applied AR to clinical medicine to help physicians deal with problems such as surgery. In short, if the cost can be reduced, AR has a great prospect.

A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.


The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.


But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
