A few years ago, Google launched the carton version Cardboard scheme, which made me experience the charm of VR/3D headwear for the first time. However, Cardboard is more full of geek meaning. In order to better experience, it has continued to try glasses boxes such as Storm Mirror based on Cardboard's improvement, but these are still not satisfied due to the mobile phone solution, which is accompanied by problems such as machine heating and serious single eye particle sensation. In addition, resource expansion and other related ecological establishment are also problems, So they basically accumulate dust at home. Recently, they have turned to focus on various HMD devices. In addition to the VR devices of Vive, Rift and PS VR, which are highly talked about, several domestic companies have entered this HMD field to make their own efforts, with cost performance ratio, VR， Each has its own emphasis on ecology. This time, I'm going to bring with me the high visibility H2 in the domestic HMD field.

Video experience:

Video is the supplement of image and text, and image and text are the extension of video.

Parameter summary:

Hi Mirror is not a VR device in real sense, and its publicity is also focused on private head mounted theaters. It can also be seen from the parameters that the fov is 52 degrees, which can only simulate the giant screen. The field angle of a real VR device is generally more than 100 degrees. The processor of H2 is RK3229. The performance is obviously very ordinary, but it is enough for video playback. Compared with other domestic peers who use amoled screens, H2 uses Sony's OLED screens. What is the actual display effect under high purchase costs? The practical experience will be brought later.

Brief unpacking:

There is nothing remarkable about product packaging, and the standard large piece digital packaging design. One side is Chinese and product drawing, and the other side is English logo and product drawing. The gross weight of the whole product is about 1.26kg, which is much lighter than similar headworn cinema products.

The accessories in the package are labeled and packaged in small boxes.

Family photo: H2 glasses, external host, HDMI adapter, charging data cable, power adapter, headset, lens cleaning cloth, instructions. As for the portable bag, it is only available to users who participate in the pre-sale.

This remote control is like the external host of Hijing H2, which supports dual band WIFI and Bluetooth connection. It can also be understood as a portable Android box. The figure compares the size with the 5.2 inch mobile phone.

Due to the built-in 7000mAh battery and other hardware modules, the overall thickness is equivalent to two mobile phones

The upper right corner is the power switch.

The front is combined with common operation keys, and the layout is basically the same as that of the mainstream box remote control. I believe it is not difficult to adapt to the blind operation with Hi Mirror. The hole hidden above is MIC, and the voice input button below is a highlight of the product. In terms of keys, the key stroke is fair and clean. The material on the front feels good, but it is easy to be contaminated with impurities.

Since it is not a full metal shell, in order to better heat dissipation, there is a set of heat dissipation openings on the upper and lower sides of the back. The three groups of identifications at the bottom, 5V=3A, 9V=2A, 12V=1.5A, indicate that it supports fast charging. The specific efficiency will be tested later.

There is a Type-C standard USB port and a full-size USB port on the top. The former is used for charging and data transmission, and the latter is mainly used for OTG external keyboard and mouse handle and reading external storage.

There is only one standard size HDMI cable at the bottom, which can be connected to the Hicko helmet or the cable splitter to meet various needs.

This is like an integration of mobile power+Android box+remote control. Although the appearance of the external host is slightly inferior to that of other manufacturers, its large capacity and integrated remote control function make the host itself no longer a burden, and in the actual test, it can quickly adapt to blind remote control. Practicality is the hard truth, even if the appearance is slightly inferior.

The package comes with an HDMI splitter, which makes it possible for the video signal of the external device to be input into HIJING via the host HDMI.

The C-port charging wire also enables fast charging to be more reliable on the mirror.

The power adapter is marked with fast charging power, and the specific fast charging capacity will be tested later.

The flat wire earphone with the metal head and tail of the earphone has a good texture, but it is 120cm long in total. It seems to affect the experience when inserted into the mirror at the head. The official website publicizes short-term earphones, which seems to be inconsistent with some descriptions. It is recommended to shorten the length. As for the sound quality, no one is better than wearing headphones, but the actual listening feeling is OK. But I'm not used to in ear style.

Initial equipment:

The volume of the head mounted display is much smaller than the one I have experienced before. Weigh 306g.

The unfolded H2 has a foldable design for easy storage. There is a eye-catching Hi Mirror logo on the front bevel, but to be honest, it is not beautiful visually. The whale logo, micro whale, Youku whale, digital tail whale and other styles are also very good. As for the main part, mirror design has been made, but scratches and fingerprints cannot be avoided.

The wearing structure ensures that even when lying down, there is no foreign body pressure in the back brain.

The diamond cutting buttons on the forehead and mirror body can be adjusted by rotating and pressing.

The wearing angle is infinitely adjusted.

High low three paragraph adjustment.

In order to better fit the forehead, a non detachable breathable sponge is designed behind the bandage, but it seems awkward for users with sweaty forehead and oil discharge, and for MM with powder puff, which makes it difficult to clean.

Hidden on the left is the 2D/3D switch button. Although Hiccup itself supports automatic source identification, some scenes that must be manually operated and custom operations still support switching through physical key operations.

The right side is for brightness adjustment, which can be multi-level adjusted. When viewing, the picture is dark? Adjust here to quickly increase the brightness of the picture.

The manufacturing process of some edge treatments here needs to be further improved.  

Press the convex areas on both sides of the bottom to move laterally to adjust the pupillary distance of the left and right eyes independently, and then move the striated gear to adjust the diopter independently. At the lower left corner is the 3.5mm headphone jack.

The design of the eye mask and nose rest can not only increase comfort, but also prevent external light from entering.

Although the material of the eye mask has a breathable effect, it will still feel stuffy if you wear it for a long time. It is recommended to take it off and have a rest in the middle of a long time. The non detachable design is not friendly enough. The highlight is the 0.7 inch Sony OLED screen with two single eye 1080P screens inside the eye mask. The physical PPI reaches 3147. The hole in the middle of the two eyepieces is a distance sensor, which can automatically pause and resume playing when removed and worn.

Connect the host to the HDMI cable of H2, and take the Hi Mirror to enter the clear screen interface. The pressure of the nose is not strong, and the external light can be basically cut off. Moreover, the design of the raised fold at the forehead connection makes it easy to half lift to view the external situation at any time, just like the double-layer glasses in the Republic of China.

In order to avoid the stethoscope effect, it is recommended that the earphone should be wrapped around the back of the neck except when lying down. In addition, it is recommended that the head of this earphone be changed to the L socket to avoid the impertinence of others when wearing it.

As the size of a single 0.7 inch screen is quite small, the phone barely snaps the above picture close to the screen. The actual display is more beautiful than the traditional LCD screen, and the screen display is quite delicate, completely saying goodbye to those years when mobile phones with 2K+resolution still have a distinct graininess when they were put into VR boxes. However, compared with the clearness in the center, the surrounding edges are slightly blurred. There is a little glare and room for optimization.

Customized system:

Whale system, HiOS， Handle firmware? If an enterprise that develops customized UI has confidence in its own system and intends to make selling points, it should have a unified name. I saw three names of customized systems in the built-in firmware and official website, some of which are not unified enough.  

The first time I saw this customized system, to be honest, I refused it. I can't say that it has no highlights, but its UI color and style details are controlled. Similar to the early MIUI, some of them are not refined enough. Both the up and down menus displayed at the same level and the left and right cyclic browsing are easy to make users feel confused and complicated, and they are relatively more accustomed to the box UI designed with hierarchical block surfaces. Fortunately, the big screen effect is better than the screenshot.

Before understanding the system, let's take a look at the specific configuration. It is different from the old RK3288 used by other manufacturers. Heijing H2 uses RK3229, the core Cortex-A17, and the dominant frequency is up to 1.5Ghz. The GPU is Mali-400MP2, which supports 4Kx2K hard solution 10bit H.265 video chips. 2G RAM. The actual refresh rate is 60Ghz, which is enough for a giant screen, but not enough for a VR device. The system is customized based on Lollipop 5.1.1. Although not true VR positioning, H2 adds a nine axis gyroscope on the basis of the first generation. So it can also realize the visual angle movement similar to VR, but the limit of the viewable area is different from the real VR.

The online video resources are OK, and the resource provider is known to be Youpeng Pule. However, many popular TV shows and variety shows broadcast on various platforms are still hard to find. The card can be turned left and right circularly, which is convenient for users on the surface. In fact, it is inconvenient for users to choose, and they think the content is complicated and difficult to locate.

There is a small animation detail in the current resource cover positioning status of the film and television channel, which is very interesting.

My content: You can view OTG external devices and local pictures, audio and video materials. The support is good, and multiple external USB storage devices can read at the same time.

App store: All kinds of TV video applications and game entertainment can be downloaded here. Common software is basically included.

System Settings: lists several commonly used items in the outer layer:, WiFi， Bluetooth, color mode, system upgrade. After clicking All Settings, the options are dazzling, and there are even theme functions that can only be seen on the original mobile phone. Many functions make it better. On the premise of no simplification, the functional styles and classifications after the second level should be rearranged. The third level cannot be all in this card form. In addition to the first level on the home page, the following forms should be changed to the list form, which may be more obvious and easy to use.

Personal center: The account system is connected with WeChat, which is better than other box systems that are restricted and cannot be used normally without login. It can also be used normally without login, but some functions such as comments are not available.

VR zone: provide VR video, application and other extensions. Although it is not a VR product, H2 adds a nine axis gyroscope on the basis of the first generation. So it can also realize the visual angle movement similar to VR, but the limit of the viewable area is different from the real VR, but it is better than nothing. It can also add a selling point to the product.

Under the VR hot broadcast, you need to manually click the 3D on the left side of the H2 glasses to enter the real full screen VR. It is recommended that automatic recognition can be achieved.

The built-in pre installed applications are quite complete, and TV versions of major video websites can also be found. The personal recommendation of TV Cat and Youku XL without advertising version are relatively refreshing, and watching third-party resources is free of advertising waiting.

The built-in browser is Flying Vision. However, clicking on the navigation site in the latest version will result in a black screen. Click the power button to lock the screen, and then click the open source button to restore the bright screen.

In most cases, the system player can automatically identify the 3D film source according to the file name and other information, support the left and right and up and down 3D formats, and its function of supporting online subtitle matching is really convenient for downloading.

The resource manager provided by the system is a rare list form, and routine operations can be done through remote control.

Scalability:

Whether an entertainment device is excellent or not, its scalability is also one aspect of users' consideration.

In fact, the headwear part of Hi Mirror can also be used as an independent display. The HDMI input headwear display of notebook devices is OK, and the headwear part does not need external power supply.

When the external host part has no external auxiliary power supply, it can also directly present the Hi Mirror system through projection when connected to the home projection.

The above is the projection output interface of Hi Mirror system, so that you can share blockbusters for everyone to see besides private theaters

It also supports Bluetooth audio output, and the effect is also good

Then try the OTG expansion capability of the external host: insert two USB flash drives, one mouse, one handle, and one Bluetooth handle at the same time, all of which can work normally at the same time.

Although the positioning is a private cinema equipment, it does not prevent me from exploring the game entertainment experience. The hand-held remote control game scene is still inconvenient. At the same time, considering the portable private theater settings, it also presents the most portable pocket key ring Bluetooth remote control in the home to test the game performance.

Play a favorite torrent on the TV box a few years ago, which is perfectly compatible and responsive. The wired handle is also OK.

Charging life:

Although fast charging is supported in terms of parameters, it is not found that the real fast charging ability can be exerted no matter whether the machine is powered off or powered on without load or charged under operation. The maximum data of the home tester is about 7W.

In order to further verify the charging efficiency, when the power is down to 8%, connect the power through the original data line and adapter. When the power is on, lock the screen and wait for charging the measured data. The room temperature is 10 degrees. It is actually filled after more than 160 minutes. The power off charging theory is faster. In terms of endurance, the battery will be used after full charge. The battery will last for about 2 hours for continuous online video, 1 hour for listening to music, and less than 50% for other miscellaneous operations such as browsing pictures.

Generally, the HMD device will generate a large amount of heat when it is charged and running. However, the temperature in the room is less than 10 degrees, no matter the external host or the headgear, the heating is extremely slight, so no temperature measuring tools will be used.

According to my consistent obsessive-compulsive standards, I refer to the five dimensional map drawn by domestic similar HMD products, and hope to give you some references.

Disadvantages:

1. The design experience of some earphones needs to be improved

2. Customized system interaction logic needs to be improved

3. Real VR game entertainment is not supported

4. The edge of the viewing interface is slightly blurred

Benefits Overview:

1. External host can be used as an independent Android box

2. The headwear part can be used as an independent external display screen

3. The integrated remote control function of the host is convenient for operation

4. The folding headwear design is relatively light

In fact, the price of 3999 is not a pit, because 4999 products with similar domestic effects have prices, which can only be said that the overall price is still not close to people. At present, there are not many HMD manufacturers gathered in this emerging field, and they are still exploring the market reaction. Hi Mirror is different from the common viewing of large screen TV and projection, but a more private and exclusive mode. Its giant screen effect is suitable for users who have certain requirements for watching movies, and also suitable for users who like to experience different game scenes. At present, the primary goal of the enterprise is to continue to improve the product experience and consolidate the user base. At present, there are a lot of junk advertisements on the official forum, and there is little communication among users. While improving the product, it provides a good common communication platform.
