Mobile VR plays a central role in the popularity of virtual reality. The biggest feature of this type of product is its portability and low barriers to entry.
There are countless related products on the market. There are products customized based on Google CardBoard, and products with self-designed algorithms that are optimized for mobile devices. In terms of experience, algorithms that use algorithm optimization and external hardware to reduce latency are even more Outstanding.
In this respect, the Samsung Gear VR of the Oculus foundry is best known. There are storm mirrors in the country that are done earlier, and one may not be known to most people. But performance and Gear VR products are on a level. The screen VR glasses launched by the Fireworks Workshop cost 199 yuan, which is less than half of the mirror 5. What is the difference between the VR glasses in the end and the storm mirror?
The low delay is very good
For virtual reality devices, anti-vertigo is also a key part of the user experience, and one of the necessary hardware for solving vertigo problems is the gyroscope.
The ordinary Carboard device uses the mobile gyroscope directly, and the delay is very obvious. The ideal solution is to use an external gyroscope like the VR of the screen, which is basically the same as the VR, Gear VR and Storm Mirror 5. This is why the three gods have better delay control.
The direct result is that the vertigo problem is solved well.
However, in the process of use, the overall delay control of the screen VR is better than the Storm Mirror 5. This is also inseparable from the optimization of the underlying algorithms and applications in the Fireworks Workshop. The official statement is based on the asynchronous time warp. (ATW), Unity Hack, Android Optimization, and more.
There is no doubt that this is the current advantage of the screen VR, and these optimizations done by the fireworks at the bottom are actually similar to Google's optimization services on the Daydream platform, but Daydream has high hardware requirements and popularity is still far away.
There is also a more interesting topic, vertigo is also related to the user's physical fitness, may some users use VR is not dizzy at all, but some users take it on the faint, so the final experience will be due to the user's physiological differences It's different.
Content is more important than product logic
When doing software design, conventional VR products are all packaged in a Hub, such as Gear VR. Although a lot of drivers and applications need to be installed in the early stage, you can choose to download it in a separate app later. Applications can also be downloaded directly from the virtual Hub in the header.
The Storm mirror mirrors Gear VR's logic, using only one Storm Mirror Pro, but the screen is a bit different. It is a few separate applications.
You may feel that downloading applications in the virtual hub has to wait and experience is not good, so choose to develop a separate application, but for the user to integrate may be a more convenient choice.
Of course, if users are accustomed to this separate operation, then it is not unacceptable, but the premise is that the number of applications is enough, otherwise the application will be independent, it will appear less, desolate.
The VR on the screen is very good on the hardware, the software is not bad, especially compatible with the Cardboard game application is better, although Storm 5 is also compatible, but the experience is slightly poor, such as the game can not be easily returned.
In general, the most important difference element of the VR experience is content based on the SDK. In this respect, in addition to the original games produced by the fireworks, the fireworks also introduced third-party developers such as Siberian Husky, and introduced video resources. The VR video content such as Youku, VR hits, and Lanting digital are subject to the objective condition that not only the fireworks, but most of the virtual reality content providers, including the storm, are facing the problem of shortage of VR content.
For an average user, when you bring a virtual reality headphone, but only look at some UGC documentaries with low quality, the attractiveness of virtual reality to people will be constantly weakened.
Both the fireworks and the storm provide local video playback capabilities. In the same theater environment, the fireworks experience is even better. The simulation and the fidelity of the ambient light are even better. They just need to be played separately in the fireworks theater. .
With regard to online video content, fireworks and storms are diced. The contents of both parties can meet the needs of ordinary users. The video interface of Storm is more convenient and rich. The local video playback experience is more realistic and outstanding. .
Lightweight and comfortable to wear
The appearance of the screen VR glasses is similar to that of the Gear VR. The same is true of the Storm Mirror. Both are basically designed according to Samsung.
In detail, the VR human-computer interaction button is set on the left side, does not support touch, Storm mirror is integrated with the button and the touchpad, the body at the top of the object adjustment knob, the bottom is less than the storm mirror Two interpupillary adjustment knobs, but support for adaptive interpupillary distance adjustment.
Open the front mask baffle, there are some subtle differences between the two, such as the screen VR phone cushion is a soft sponge, feels very comfortable, but easy to leave scratches, and storm mirror is not easy to leave the draw Traces, but rubber, both using double-convex aspherical lenses.
In order to wear comfort, the glasses are made of sponge liners and they are all fastened by Velcro. The frame is made of soft rubber, which can adapt to different users' facial shapes through deformation.
From the perspective of user experience, in addition to the need for special attention to the face and material, the appearance of the virtual reality heads is not the most critical place, after all, you have to look at the content and experience.
As one of the factors affecting the experience, the weight is also critical. The screen VR glasses have a weight of 260g, which is 10g lighter than the Storm mirror, and has a slight advantage.
In terms of heat dissipation, both devices have built-in simple air outlets. On the one hand, the temperature at the time of the use of the device is reduced. On the other hand, the lens is prevented from being atomized. However, the effect is general and long-term use is not recommended.
In addition, for the purpose of saving power and calibrating facial positions, the extreme screen VR and the storm mirror also have a rectangular infrared distance sensor between the two lenses, with a light screen on the screen instead of the lock screen for the battery life and use. In terms of the experience in the process, all are good, except that it is troublesome to pick up screenshots and other unconventional operations.
Human-computer interaction is too dependent on keys
PC-level VR generally has a controller, so human-computer interaction is generally controlled by the use of the handle, but still need to perform a number of settings on the PC before use, moving VR does not need to be so bothersome, and sometimes a few keys can also Now.
The VR-based human-computer interaction relies mainly on the three button returns on the left side of the camera, A and B, and there is no volume control (meaning is not significant).
Storm mirror is completely copied the Samsung Gear VR program, using touch instead of A and B buttons.
Taking into account the actual operation is carried out with your head, this time you will find that the touchpad operation experience is how bad, because you can't guarantee that one hundred percent complete the operation, so that in use Had to often take the head off to confirm the position, does this mean that physical keys interact 100% better?
Not at all.
For example, a simple confirmation operation in the application, but also need to press the button to deal with, it seems a bit troublesome.
At this time, the human-computer interaction program should be selected, such as focusing the headlight on a certain button and staying, simulating the confirmed operation, or simply the head control. This is also one of the interaction modes of the Gear VR. Of course, Samsung takes care of it. Some users' habits also preserve the interaction of buttons and touch confirmation.
In addition to key interactions, the interaction between the handles is also crucial. For example, for some specific games, if you still have to use the buttons on the head to control, the experience is still somewhat inconvenient, but considering the price of only 199 yuan, it is understandable. But it would be perfect if we could combine the long-term focus of this gesture-like interaction.
UI design still has room for improvement
It does not look good or good-looking, and it is generally loved by radish cabbage.
Before using the screen VR, after installing several matching applications, connecting the mobile phone and glasses, you can start the application automatically. This part is relatively reasonable, except that after you wear glasses for the first time, the eyes are huge and elegant. The use of black fonts suggests that although large fonts can be easily read by the user, they are less aesthetically pleasing.
The entire home screen is set as a room scene, and the center is the tile style UI. This is the same as the logic of most VR devices. The difference is that the environment setting of the OS is slightly rough, and the ratio between icons and fonts is not Very coordinated.
The OS of the screen OS is really considering the trend of flattening towards the time being. This method of adapting to the appetites of the masses of users is correct, but the flatness is not thorough enough. I think this should be outside the technology and it should be the most limited solution. The problem is that compared with providing a good user experience, it is also necessary to please consumers.
Summary: Getting the delay is the first step to success
Fireworks once said that he is the earliest and most technologically strong team in the field of mobile VR in China. This is indeed reflected in the optimization of the underlying algorithm. The low-latency water quality of VR glasses has been at the forefront of the industry. This point, even the first group of storms on the VR team in the country can not be compared.
From a preliminary perspective, technology conversion has been reflected in the first generation of VR glasses. The delay in hardware control is only the first step in the success of fireworks. The next step is to introduce more content. This is the need for continuous improvement in the industry.
Storms far exceed the number of fireworks in terms of volume. Simply put, storms have money, you can buy content, you can integrate resources, you can also set up a huge team, fireworks may not reach the overall strength of the storm, but experience close to Gear VR price Only 199 yuan of products, but the storm did not do it.
