The technology website Ars Technica recently released a review of the Google Daydream virtual reality helmet. The site believes that if the user already has a compatible Pixel phone, this product is worth buying. But if you want to get the best virtual reality experience based on your smartphone, you should still choose Samsung's device.
In the developing virtual reality ecosystem, Google Cardboard plays the role of fast food burger. It's inexpensive, but it still gives users a basic virtual reality experience. However, this is undoubtedly a low-quality product that cannot compete with other helmets that are more expensive and need to be used with PCs and game consoles. The latter is more like a well-prepared meal.
Also analogous to food, Google Daydream is more like enjoying a meal at an affordable casual restaurant. Although the price is slightly more expensive, the quality is significantly improved compared to the virtual quality virtual reality of Google Cardboard, and it is also equipped with a smart handle.
However, Daydream is far from being comparable to the top products of the Virtual Reality Pyramid, and even there is a certain gap between terminal devices such as Samsung Gear VR.
helmet
Like the previous Cardboard, Daydream is just a simple jacket that uses a set of lenses to transform the picture on the phone's screen into something that is compatible with the virtual reality helmet. Daydream itself does not contain any electronic components: visual content, processing speed and angle detection are all provided by the phone.
Because of this, Daydream offers the simplest virtual reality helmet setup experience available today. On the compatible mobile phone (currently only the newly released Google Pixel mobile phone is eligible), after installing the Daydream app, you can open the front panel of the helmet, insert the phone and then fasten it with the rubber band, then put it on your head, and finally adjust the head. The belt can be elastic.
In addition to downloading software, it takes less than a minute to start experiencing the world of virtual reality.
The absence of any electronic components, coupled with the use of lightweight and breathable fabrics, makes Daydream more comfortable to wear. It is not necessary to stretch the elastic band too tightly to ensure the stability of the helmet. Since the weight is mainly applied to the eyelids and behind the head, the nose only bears a little pressure. After a long period of use, Daydream will also leave a red mark on his face, but it will never make you sweat like a heavy-weight helmet like HTC Vive.
The Pixel screen generates a virtual reality image with a resolution of 1080p, which is very good for a smartphone. When the head is turned in a 3D environment, the edges do appear distorted. The user is indeed able to resolve a single pixel over a short distance and create a "window window" effect between these pixels.
But despite this, when you stare at the three-dimensional world in front of you, you don't distract too much energy because of these factors. The main reason for this effect is that Google's application design allows users to see smooth images when they turn their heads. Simple objects in the game are rendered with sharp and sharp lines, but the head tracking does not include position tracking, so tilting forward or left and right still feels weird, as the entire virtual reality scene moves with it.
The worst aspect of Daydream's visual performance is the narrow view. It is impossible to judge the specific angle of view, but as long as you look at it, you know that it is far less than 100 degrees, and it is far less than the range of other virtual reality helmets. It feels like watching the entire ocean through a small porthole on the ship.
Daydream's breathable design also caused a large gap between the helmet and the face. This can improve comfort, but if the room is too bright, light will penetrate the helmet. When the dark scene appears on the screen, I need to cover the edges with both hands to block these annoying lights.
If you're going to use Pixel to provide a virtual reality experience, you have to understand one thing: After running in virtual reality mode with extremely high processor requirements, the phone will become incredibly hot – After using it, just holding it in your hand for a while will make you feel unbearably hot. Due to the extremely high CPU requirements, it also has an impact on battery life. A fully charged Pixel can only last 2.5 to 3.5 hours in virtual reality mode.
handle
In addition to design, the real difference between Daydream and most of the previous mobile virtual reality helmets is that it includes a handle. The overall feel of the handle is like the mini version of the Wiimote handle, and the built-in accelerometer detects tilt and basic hand movements.
In most cases, this handle acts as a virtual laser pen in the virtual reality world. Users can complete various actions by quickly twisting their wrists, which can select the next navigation point in the 3D world. Can use the virtual keyboard to enter information. Other games may use this handle as a steering wheel or explore the user's movements in a bowling game - this is similar to the Nintendo Wii.
Daydream has a small touch area under the thumb that can be used to flip through options and mimic the use of the arcade joystick. You can click on the trackpad to determine the option. But in addition, there is only one "action" button on the handle, so don't expect to use it to operate an overly complicated game. There is also a volume button on it so you don't have to take the phone out to adjust the volume.
Although this smart, lightweight toy handle is very intuitive, there are some important issues encountered during actual use. First of all, too sensitive tilt sensing technology can make users crazy. After using an app for a few minutes, you'll notice that the angle of the laser pointer in the app is quite different from the actual angle of the handle.
In other cases, the laser pointer in the game may shake, but your hand has remained motionless. At this time, you can press and hold the home button for a few seconds to reset the action detection "center". When you are concentrating on the virtual reality experience, this situation does bring a lot of trouble.
In addition, because the handle cannot sense the position, the virtual handle seen in the helmet is usually not in the same position as the virtual handle held in your hand. It sounds like a small problem, but when you concentrate on enjoying the virtual reality experience, this disjointed experience will greatly distract you.
platform
Unlike Carboard, Daydream doesn't use the Google Play platform, but instead uses its proprietary platform and store to distribute compatible apps. Whether in a virtual reality environment or on a mobile phone, this app store is very easy to use. It also provides a smoother experience to help users find and buy games and apps.
But in the early days, there was still a lot of work to do because there were fewer application choices. The initial game was less than twelve, and I would not recommend users to run on any of these apps for more than five minutes. The dominant ones are simple puzzle games, most of which do not take full advantage of the virtual reality perspective, and many do not make full use of the somatosensory handle.
Daydream users can also find a very ordinary racing game, as well as a very ordinary bowling game, plus a few simple dungeon escape games. Every game seems to be developed in a hurry, making people feel that virtual reality is just a meaningless moment of fanaticism, can not appreciate the all-encompassing feeling of other helmets.
In addition to the game, Daydream performed slightly better on "experience" content. For example, the YouTube app provides a great interface for users to view more and more 360-degree videos (but many videos have very low resolution when viewed through Pixel). Google's own Street View app also performed well in the virtual reality environment, giving people a near-realistic experience, as if they were really in it.
The Google Photos app performs better, allowing users to see stereoscopic landscapes and listen to accompanying music and background sounds. Coupled with the Cardboard Camera app - you can use your Pixel phone to take your own 3D panoramic photos - and provide a first-class experience, perhaps the closest Daydream service to the killer app.
In addition to Google's virtual reality applications, several companies have also launched content that provides 360-degree video and experience. One of them comes from the Guardian, which traps users in a virtual cell to simulate the feeling of solitary confinement. This also allows us to feel how virtual reality will be used to tell news stories.
to sum up
If you've already used Google Pixel as your main mobile phone (or plan to buy such a mobile phone) and want to get a virtual reality experience in a cheap way, then it's a good idea to spend $79 to buy the Daydream system. Despite the limitations of visual effects, handles and application choices, it is very comfortable to wear and the price/performance ratio is relatively good from an experience point of view.
But if you consider virtual reality as an important consideration when buying a new phone, we recommend Samsung Gear VR and its compatible Galaxy phone. At almost the same price, Gear VR can provide a better viewing angle, better block the ambient light, more compatible mobile phones, more rich content, and more reliable control (although raising your hand) It’s a bit of a hassle to use the touchpads on both sides).
If you want to get the best virtual reality experience of today, it obviously shouldn't be realized by mobile phone. HTC Vive, Oculus Rift and PlayStaTIon VR are the best choices today. However, in addition to the expensive helmet, you may need to invest in a computer and game console.
But if you can't wait to enjoy the "big meal" in the virtual reality field, then Daydream is obviously more "delicious" than the Cardboard.
