What is the connection and difference between virtual reality and augmented holographic images? What about Google Glass and Microsoft Glass?

Hello, love application -—WPer, let me answer for you first:

It is slightly different from virtual reality technology.

It is understood that Microsoft's holographic glasses HoloLens have built-in CPU, GPU, spatial stereo technology and holographic processing unit, which can be regarded as a personal computer. From the official video provided by Microsoft, after wearing HoloLens, you can get all kinds of virtual information in real time and interact with it. In the game "Mars World", players seem to be on the surface of Mars, surrounded by sand and stones. In the real world, the surface of the coffee table can be "destroyed" immediately by clicking it with your finger. Looking down from the damaged area, there is a cave full of lava.

Unlike virtual reality technology, HoloLens uses "augmented (mixed) reality" technology. Translucent glasses do not affect the wearer's ability to see the real environment clearly, and he can still walk freely and talk with others without worrying about hitting the wall, but he may instinctively avoid the probe car that does not exist in the virtual "Mars" world.

If you open the Skype application in HoloLens, the contacts appear in front of you like cards. If you tap a contact in the air with your finger, the glasses can automatically call him. During a video call, you can see his environment through the other person's HoloLens. If you design toys in this virtual world and print them in 3D, it really feels like a "magic pen".

It is understood that the principle behind "holographic glasses" is to induce your brain to regard light as matter. There are several cameras with different angles symmetrically arranged above HoloLens glasses, which are responsible for detecting body movements. The sensor receives data all the time, and then gives it to the core CPU, GPU and HPU for processing. There are buttons on the right side of the glasses to adjust the volume and projection focal length, and the screen can also be adjusted by simple gestures when using.

This "holographic glasses" is called by foreign media as the first "touchstone" to test the reputation of Microsoft's new CEO Nadella for innovation and creativity. According to Alex Kipman, the person in charge of the project, the project has been going on in secret for seven years, and even most people inside Microsoft don't know the existence of the project.

If holographic display, holographic photography, aerial touch and other technologies can enter the civilian market in large quantities, it will set off a revolutionary subversion in the entire 3C industry. "Cutting fruit in the air" is a piece of cake, and doctors can preview it intuitively before operation, estimate the risk and improve the success rate of surgery; Military commanders can directly project three-dimensional topographic maps through holographic screens; Teachers can teach vividly and entertain.

The industry expects that Microsoft holographic glasses will be listed this year.

The "revolution" of smart glasses has long been started by Google Glass. However, from the current point of view, the former is a bit "chicken ribs." Can Microsoft holographic glasses succeed? Similar to smartphones, Google Glass can take photos, complete Internet searches and run applications. However, Google Glass was regarded as "invasion of privacy" from the beginning, and many public places said "no" to it. Although doctors and other professionals think it is very useful, a small number of applications have not attracted the interest of the mainstream market.

But the function provided by "holographic glasses" is not to "shoot others", but to create a "virtual space" for users. Compared with Google Glass, it is fundamentally different in technology and application.

Kzero, a market research company, predicts that by 20 18, the sales of vr-platform will reach 2.3 billion US dollars (about 14 1 100 million yuan) and the sales of software will reach 2.8 billion US dollars (about 172 billion yuan). Last year, Sony released the virtual reality head-mounted display project Morpheus；; Samsung launched the virtual reality device Gear VR；; Facebook also spent $2 billion to acquire Oculus VR, a manufacturer of virtual reality equipment. The giants can't wait to occupy smart TVs or other screens and directly start the "competition" for the retina.

Judging from the products of the "Holographic" family, the 3D holographic projector Bleen can project a virtual 3D image into the air, so that a stereoscopic and vivid "person" can stand in front of you. Takee, the world's first holographic mobile phone that won the "CES Innovation Award" at this year's CES show in the United States, showed a vivid "holographic picture".

In fact, Jeepman, the developer of Hololens, said that HoloLens is still in its infancy. "Before full commercialization, the machine itself still had many defects, such as no keyboard. Once there are voice and gesture control problems, users will soon give up this interaction. " In an interview with Guangzhou Daily, Microsoft did not disclose information such as time to market. However, Microsoft officially stressed that it will be launched within the timetable of Windows 10.

Foreign media analysis believes that the main defect of HoloLens is "gesture". "If you want to choose an item, you must first look in a certain direction and then click with your finger from a distance." However, the reporter who was invited to experience found that after clicking on the item, the response of HoloLens was somewhat delayed, and it was difficult for users to click on the item accurately.

Discussion:

Will "illusion" lead to "division"?

"In the future, the computer field will no longer revolve around the original digital world, but use words and gestures to simulate the world. This new world needs a completely different set of rules of the game. " Alex Puntland, director of the Human Dynamics Laboratory at MIT and known as the "father of wearable devices", said that the most important part of wearable devices is the sensor. To truly realize the natural interaction of wearable devices, voice, image and somatosensory technology can't be left behind.

However, holographic technology makes the virtual world appear in reality, which inevitably makes people worry: what kind of future will the world full of "illusions" bring us?

In the interview, the reporter found that many young people who pay attention to science and technology "clap their hands and applaud" this technology, calling it "a few blocks away from Google", and some people expressed concern. A Lei said: "There are not many' virtual worlds' now. Everyone shows themselves in the circle of friends and sees others, but it is difficult to communicate in the real world; If even the real world and the virtual world can be stored in a pair of glasses, will there be a sense of "division" and changes in mentality, personality and even brain nerves? It's a little scary to think of it. " Xin Wei said, "Is it really good to regard your home as a spaceship and think that the steps in the bathroom are the edges of skyscrapers?" Only you can see' your world', others will feel puzzled, and people may be more easily divorced from the real world and the people around them. Some readers are also worried about "hallucinations", "Do you have headaches or nausea" and so on.

Noun explanation:

What is holographic photography?

"Holographic display technology" calculates the actual holographic image based on the holographic image data model by tracking the visual angle position of the human eye, and then accurately projects the stereoscopic images of the left and right eyes onto the retina of the human eye through a special directional display screen, so that the human eye can produce the same visual effect as the actual environment.
