Microsoft HoloLens evaluation of foreign media summary is not perfect yet enough shock

Tencent Digital (Wang John) HoloLens is an augmented reality device released by Microsoft in January 2015. In late March 2016, Microsoft announced the HoloLens Development Kit in the United States and Canada, but the device is limited to developers selected by Microsoft. use. Until August 2016, Microsoft's HoloLens officially began to open purchases to U.S. and Canadian users, priced at 3,000 US dollars (about 20,427 yuan), but this is only the development version of the price, business suite includes security and device management capabilities plus The price of the warranty is 5,000 US dollars (approximately 34,045 yuan). On October 13th, Microsoft announced that HoloLens head display will be simultaneously listed in six countries except the United States and Canada, namely, Australia, Ireland, France, Germany, New Zealand and the United Kingdom. Users will start to send in November after booking. goods. In terms of price, Germany, France and Ireland sell for 3299 euros (approximately RMB 24,372), the United Kingdom sells for 2719 pounds (approximately RMB 23,325), and Australia sells for A$4369 (approximately RMB 22,460). New Zealand is priced at 7,829 New Zealand dollars (approximately RMB 37,928).

With the continuous increase in the scope of sales, more and more people around the world have already got this head of the HoloLens. Although there is currently no news available in China, domestic players are already gearing up. Here's a look at some of them: Foreign media evaluation of this advanced augmented reality device.

HoloLens provides an unprecedented augmented reality experience. Its excellent workmanship and attention to detail are absolute advantages. It can be said that the application potential of HoloLens should be unlimited. But the question is whether Microsoft can solve some minor problems and how much it will cost the average consumer to buy. HoloLens is Microsoft's augmented reality (AR) head-mounted display and feels like future technology. When I wore HoloLens on my head, it felt like I had a computer in my eyes. Although there is no special feeling, the real and virtual scene can be seen at the same time.

The $3,000 (about RMB20,427) AR head-mounted display uses a 24-core processor. Microsoft claims that it has a battery life of up to 5.5 hours, and if used heavily, it can reach 2.5 hours. Listening to general endurance, compared with laptops and mobile phones on the market, battery life is almost beyond this level, but these devices can not play 3D and AR video. HoloLens consists of two ring structures with a thick outer ring, a plastic construction, and internal hardware. The inner ring is narrow and fitted with a pad that can wrap around the head. The inner ring can be adjusted by the rear roller, which can slide forwards and backwards. The contact area of ​​the pad is not large, and it is easy for the user to forget its presence when using it, thus focusing attention on the AR image in front of the eyes.

The device did not require nose bridge support, but when used it was found that it always slipped to the nose, no matter how many times you pushed the HoloLens forward. However, nasal protection plugs are additional accessories that can be removed and may be removed better. Not every time you wear HoloLens, you can easily wear it. The helmet must be constantly re-tightened, repositioned and realigned. When everything is adjusted, you can see the panoramic AR image. If it is too tight, too high or too much forward adjustment, it will affect the user experience. Standing for use helps to get the best panoramic experience. When I move around, it's difficult to adjust to the right place. Of course, moving is one of HoloLens's important functions.

Despite this, like all VR and AR helmets, the weight of the HoloLens is concentrated in the front, and when you wear it, you obviously feel that the forehead is under a certain weight. Weight can be uncomfortable but not obvious. If Microsoft can shift weight to both sides or back, it may reduce the weight of the front. I usually wear glasses with myopia and also wear glasses when using HoloLens. The glasses will not be squeezed into the face and will not make the head feel taut. At this point HoloLens does better than other VR helmets. In addition, the use of HoloLens has no nausea, as was often the case with previous Oculus Rifts. After wearing HoloLens, you can still see the surrounding environment. You will not lose your sense of direction, nor will you have claustrophobia. It's not easy to move backwards. I can't quickly turn to see what's behind.

HoloLens is a high-end device, both from the outside and from the feel. Its price is not cheap, this point can already be felt from the developer version of the price, more suitable for professional use, of course, can also be used in the living room. If you want to use it on a construction site, it may be difficult to keep the HoloLens clean and free from damage because the HoloLens is too weak. I am very careful when using it. It's best to hide it where children can't get it.

In actual experience, the hologram consists of several parts: two floating spheres, two yellow pieces of paper, and some boxes stacked on a stack of paper. The program is called "Project Origami" and looks like an origami game. To make the hologram really usable, I added some controls (gazing, gestures, voice control), spatial sounds, spatial mapping, and I could pick up, move, and place holograms in the room. Finally, I entered an underground world. When the ball fell, there was a big explosion. A hole was blown out of the floor and the ball fell. Looking down from the cave will reveal a new world. Rolling hills and cranes rise from my feet.

The images displayed by HoloLens are combined with real scenes, vivid and clear, very realistic, and even a little nervous. When I move the image, the hologram is like a real object, and I can see the back scene at the same time. When the paper ball rolls on the floor, the effect is the same as the actual ball rolling. The ball will bounce up and it looks like you can all go with your hand. When we gaze at the open underground world on the floor, it seems that there is a new world under the floor, but I have not found it.

Watching a hologram overlaid on the real world is only half the HoloLens experience. Its other major function is to control the holographic image. The control of the HoloLens image by gaze is fast and easy for any user. Other input methods are slightly more complicated. Although voice control can be used, there is a certain delay between the release of fate and the execution of the hologram. When I send a "roll" command to the ball, the target waits 2 seconds before it starts scrolling. Although the time is not long, this delay is still unacceptable. Gesture control is the hardest operation of HoloLens, and although I just swipe down with one finger, I still spend a lot of time figuring out the best distance to slide and where the finger should start to slide. Can you imagine a person sliding a finger in the air, isn't it funny? But in the end I still adapted the best way to slide, and the control experience was better than expected. Do not touch the hologram. Just put your hand in front of you and operate it comfortably. The sliding effect will be the best. Through gestures, I can select the "Project Origami" image, which can be fixed in the new position by staring at the room and then pinching it. You can also move the image from your eyes to a sofa, coffee table, or other place. Although the experience is not as perfect as in the film "The Minority Report", it has left a deep impression on me.

After the Microsoft HoloLens head was launched in the UK, I performed some experiences to see what effect this device could achieve. After trying, feel that HoloLens has a completely different experience. When you bring this device, the real things around you will be displayed in front of your eyes, and then the things in the virtual world can actually appear in the real scene. I saw a Tyrannosaurus rex sitting in the living room, I could walk around it and it felt very real, although I knew it was just a digitally synthesized animation. It suddenly snarled at me and it was terrible, so I reduced it to the size of a toy by hand gestures, so that it would not appear so terrible.

In fact, this is a game called Actiongrams. This kind of feeling is different from common visual effects. It does not require much experience space. This dinosaur model is not only designed for entertainment, it can be used to create movies. , TV characters, or as a prop appear in various scenes. Directors can walk around the things they create so that they can examine all aspects. Helping to create 3D content is one of HoloLens' two main functions that contribute to the development of the entertainment industry. 3D objects (such as product design, fashion and architecture) previously created on computers can be placed in real scenes through HoloLens.

In addition to helping create 3D models, HoloLens can also be used as a general consumer product. Before the presentation, I saw a luxury watch experience created by Microsoft for presentations. The CG rendering of the watch floats in front of me and opens in 3D space to show its components. I can select each area in turn, display a label and get a detailed explanation of each part of the watch. In the VR demo, you can see a starry sky. When you turn to see the stars, you will find the movement model of the solar system. However, the picture is relatively simple, but it shows that HoloLens can explore as much fun as VR, which is very important for using HoloLens to create a truly attractive experience.

In the first demo, I saw a full-size human body, and we can add or remove layers to dissect it. I looked at his internal organs and the beating heart and saw that his bones were broken in different ways (used to compare horizontal fractures and spiral fractures). You could walk around the 3D skeleton and see more details.

Information-age

As Microsoft's HoloLens began to book in the UK, more and more players began to experience this product. I first entered Microsoft's product showroom, but HoloLens felt different from what I had imagined before. What I was looking for was a complete virtual reality experience, and HoloLens was a hybrid reality device that could The combination of the world and the virtual world makes users feel that 3D images are real. It also creates an artificial sensory experience that is like a device in a science fiction movie, but it is not yet so advanced. This device is not yet able to provide holographic projection. Instead, it displays the real world and the virtual world in front of the user through the head display, thus realizing a semi-immersive VR experience. He doesn't need to have another headset, and his head can make a sound.

HoloLens contains the world's first holographic computer, with two environmental sensors and a depth sensor, allowing real-time processing of acquired information. Leila Martine, Microsoft’s director of product marketing, said “We call it spatial mapping.” According to Martine, advanced holographic processors (HPUs) allow a mixture of interactive displays between the real world and holograms. I must admit that I was impressed with the trial of the HoloLens head, with a clear hologram, strong interactivity, and obvious advantages in various commercial applications. Although this technology does have some way to go, Martine said, "Our journey is only just beginning, but it is already very exciting. In the future, we will launch even more incredible products."

Through the actual experience of HoloLens, I have become a die-hard fan. This is a very cutting-edge technology. Although it is not yet perfect, this technology has the potential to change the traditional business practices of various industries. Virtual reality and hybrid (enhanced) reality are the two hot technologies this year and will infiltrate all walks of life in the future. However, since Hololens has just entered the market, there are still some technical problems, such as limited vision to a certain extent, consumers will need time to adapt. However, I will continue to upgrade this technology in cash. This technology will one day become an integral part of our production and life.

HoloLens looks like a consumer product, which is something sooner or later. This head is made up of a pair of concentric circles, like two rings of a 3D solar system. The inner ring surrounds your head and tightens with a bicycle helmet ratchet. The front of the device is affixed to the forehead, and the back of the device is behind your skull. When you start the demonstration, you can see that nearby objects appear around you. In fact, they are all virtual and do not exist at all. Only you can see it. The CG bird is as small as the top of your TV, or the feeling that your feet are on the surface of Mars. You can select applications from similar Windows menus, but you can also "place" them in the real world. As long as you bring your head up, you can clearly see them appear in the real world, but this is not a holographic projection image displayed on your side, only in your head display. The display screen is about the same size as a smartphone, and it is close to the head. You even feel that the virtual object is a little away from you. You can still hear them because of the built-in 3D speakers.

If the virtual pattern is large, such as a person, you may only see the top of them. Until you look down, otherwise their lower part is invisible. This means that a virtual web browser or a virtual TV screen covering the wall will not work because you can only see a small screen at a time. HoloLens feels completely different from the Oculus Rift or HTC Vive helmets. They show a completely non-existent virtual world. In addition to displaying the virtual world, HoloLens can also combine the virtual world with your surroundings. It's a feeling of creating immersive conditions.

For control, you can grab and adjust the size of the virtual object. You need to stretch and bend the index finger in a very specific way to operate them “in the air”. You can also control by issuing voice commands, but Microsoft's Cortana personal assistant is still incomplete and often incorrectly recognizes voice commands. Another problem is that this stunning holographic image is centered on the view in front of me. I have to adjust or tighten it often, until I feel that the bondage is tight and the image can be stabilized. I later found out that it was equipped with a pair of optional headbands, which, like the baseball caps, should be tied right from the start.

Of course, you should also know that HoloLens has only 2-3 hours of battery life, which means it can hardly work outdoors. In a dark room, the hologram displays very well, but in bright places, holograms are sometimes disturbed. Microsoft did not try to hide the current defect of HoloLens. They know that this technology is not yet ready and the Oculus Rift virtual reality helmet has two development kits before it becomes a real product. I have spent a lot of time to experience. They also have many defects. But after experiencing HoloLens, I think this device has unlimited potential and will one day fit into our lives.

to sum up

Whether it is software or hardware, HoloLens is not perfect. However, it is believed that through continuous improvement, HoloLens will become an excellent immersive entertainment device. Despite the flaws, using HoloLens is still pleasing. When more powerful applications, more reliable features, and improved viewing experience are available on the market, HoloLens will become an AR viewing tool. There is no doubt that HoloLens will change the way we interact with the world.
