Even if the concept of virtual reality have decades of history, but with the present level of science, to be the sword Dominion-like virtual gaming experience is still a distance and watching Oculus Rift over $ 350 price, I am afraid that we all feel tired love.
But in Goolge Cardboard under the wind, storm also launched its own virtual reality glasses-mirror of the storm. 99 price also provides Bluetooth joystick, which set a new floor on the price of virtual reality glasses, but what is the actual performance, take a look right now.
Appearance and workmanship
Machines using simple kraft paper packaging, reads the product name and the slogan "2 hours away from the Earth." Alexander McQueen
Limited by cost, packaging easier. Product in a clear plastic tray, annex only a small remote control, instruction manual and warranty card.
Face is a big glossy cover, this side does have "mirror" flavor, but polished plastic surface is easily contaminated with fingerprints and dust.
The entire "picture frame" double trumpet-shaped, concave nose position reserved bits.
Area a bit larger than the normal glasses lens and eyepiece (closest to the eye), there was a thick, wide sponge gasket, wear a cool.
Glasses and there are three elastic straps help glasses safe in the user's head.
The front cover can be opened about 45 degrees forward, can fit inside mobile phones.
Opening and closing of position fixing with magnets.
Cover plate inside is a thick piece of foam, to suit different thickness of the phone.
Mobile fixed sides, cushion used to protect mobile phones. Here you can see, glasses around the field were completely separated.
In order to provide the vision, lenses are doing great and edge sharpness, lens focal length is large, led to the mirror is very "open".
Joystick mini in size, is made of nubuck material on the surface. Joypad joystick is the upper left corner, right corner is the manufacturer logo.
The other side completely symmetrical. Although it looks like the kind of skin coating, but in reality its whole is hard plastic.
Joystick reminds small button set more reasonable, it feels good.
Joystick front three buttons a, b, c.
Raised on the b button, allow blind users to operate. Touch and remote control toy remote control button are similar, shorter key travel and feedback hard and larger buttons on the game controller.
C buttons are set up in the grooves, press the small finger larger users may feel pressure not.
Top of the joystick is a joystick and confirm key (and power), here is a status indicator lamp.
In order to prevent flying off, joystick design lanyard hole in the bottom (see screws on the right).
Remote joystick with two AAA batteries.
Opens the official application and turn mobile phone into a predetermined position, close the lid you can start work.
Lenses than normal lenses of the telescope to a large circle, led directly to the entire machine is huge (see hand size), even with similar glasses can also be used.
Look carefully can see concentric grooves on the lens, estimates were used to remove the screen grainy and wavy.
Pictured above is the real figure. Using Google users are likely to know of the VR glasses such as Cardboard, as too close to the eyes away from the screen, so even a 5 inch 1080P screen (PPI-441) will see grainy, but mirror real visual experience of the storm did no visible particles.
Estimates for two reasons, one is the official specially big and focal length of the lens, so the screen distance is larger than the average VR glasses second concentric stripes of its lenses, may has certain effect against particle and wave.
In addition, the project without the wheel and adjust the interpupillary distance by eye the breather hole, officials said on the officially released version is added. But the author is curious, interpupillary distance adjustment wheel structure is more complex, the official version really had time to add it?
Principle and application
"Virtual reality" in plain English is the device a/reproducing human senses, including but not limited to, vision, hearing, sense of smell, touch, temperature, and so on, including vision and hearing is the most important and most feasible.
And before the brain-wave technology, mankind must provide "into the" method of visual perception, there are only two: make the screens bigger, or to shorten the distance between eyes and screen. Obviously virtual display glasses with the latter, it on the big screen at the same time, isolated from extraneous light, it will create the illusion of a into another space.
Plus three-axis gyroscope, accelerometer and other position sensors help, the picture will be able to follow the movement of the wearer's head and make appropriate response, visual feedback that closely resembles reality. And the rest is sound and touch, but technical constraints, only vibration now tactile feedback ... ...
Hardware, said storm mirror glasses/helmet for fixed phones, which focuses on official app and joystick, which makes Visual content feedback can be made according to the user's head movement and offers real-time manipulation.
Uses, in addition to your regular 3D film, nature is the first person games, machine control, the virtual experience (Vista, virtual exhibitions, and so on). Alexander McQueen iPhone 6 plus
Use
Virtual reality equipment package by the mirror, joystick and phones of 3-part. Joystick after the mobile phone through a Bluetooth connection, the mirror responsible for d and into the horizon, phone interface, joystick provides instructions.
Its key function diagram as above. Joystick here is actually a Bluetooth gamepad, hands-on reaction was swift, rocker handle thick PS games.
After entering the application, above phones will look like, the display will be divided into the left and right eye images of two different, and point of view of their content will be minor gaps (left eye Parallax).
Home lay on the "local and online videos, games, live experience" 4 core function of icons.
Local video comes with three-d show, opportunity to make vibrations to enhance realism story.
Playback support for 2D, 3D, and the split-screen modes, switch around. Pictured above is in 2D mode.
Actually there are 4 split-screen mode. 4-way play avatar at the same time, the processor a great PEAR, Caton appeared even millet 3.
Of course, it can also be on the cell phone of another video algorithm in 3D, you can directly watch local films and my own video.
Online video is similar to PS game options screen, through the up and down arrow keys can be used in "TV, movies, anime" toggle switch in several categories, and the left and right arrow keys is jump in the sources of the same type.
Its classification can also click on the card, enter the usual display mode, but true 3D source only 8 ... ...
"Site" function is actually a holographic film. Just put a helicopter the holographic film, playing user perspective will change according to the direction and angle of the head.
The user can also press a button to stop a moment, 360 degree holographic appreciation. You can control space and time feeling like a matrix, slightly cool XD
Games, the official only to provide the town of fairy tales, horror Manor two paragraphs. Fairytale town is a first-person perspective game, through rod, control characters in the fairy town around, but for the time being seem to recruit or develop a class function is not set, so it was a pure 3D fairy tale town at the moment.
Horror Manor is also controlling role in a personal tour of the 3D scene, should be an adventure puzzle game. Game character's field of vision is limited in the context of a flashlight, well and create an atmosphere of terror. There the key tip, can do part of the interaction, such as picking up a piece of bone. But IQ needed recharging, have not played out why Glen Johnson.
Operation experience
Experience virtual reality glasses, mainly under the influence of several parameters:
Wearing comfort: mirror of the storm with a lot of cushion material, can provide great wearing comfort. Just frame weight, measured the weight of 225g, plus 145g phone, 370g the overall weight, wear is not a problem for a short time, but if you want to use for a long time, it is recommended to use lighter phones ... ...
Dizziness: this is a 3D visual of the metropolitans, and severity from person to person. If you watch 3D movie will have a hangover, it is recommended that the next generation of 3D technology. Mirror of the storm itself was used in the holographic film position feedback, when everyday for the movie, it is more of a "big-screen" equipment Vertigo is very light.
Mode of operation: the official standard lever feels good, plus bonus three-axis gyroscope, controlled experience shouldn't be a problem.
Head tracking sensitivity: holographic film, it is estimated that official was deliberately lowered the head tracking sensitivity, glasses to ignore the many small quiver in order to guarantee the stability of vision, is quite comfortable to use, but if you need high-speed response of shooters in a stick.
Application simulation: including games and holographic films, two of the official game is still in a relatively early stage, and is limited by the mobile processor power, the screen is also not too fine, but makes sense of virtual reality into the user experience is more than enough.
Definition: in this and in the glasses directly related to cell phone, cell phone screen higher PPI, look more delicate nature. Because they split the screen, after fusion of the human eye, the real, can see only half the resolution. Even the 1080P screen, finally perceived resolution only 920*1080, which directly led to two results: the screen that you see is a square, and the picture is elongated ... ...
Price and fitness models
Storm mirror costs 99 Yuan buying patterns is similar to millet's "official site snapped up", now still in the project stage.
Only devices that support Android 4.0 or above, need phone has Bluetooth and gyro sensors. Recommended screen range 4.7-6 inch, maximum size for 15.8cm*8.5cm. But millet 2 measured 4.3-inch screen also can work in it, but viewing area will be smaller.
Compatible models, its Qualcomm and Samsung's Orion processor compatible with the best, millet Meizu models such as natural a cinch. But before you buy, it is recommended to look at the official Forum models compatible form.
Competitors
Virtual reality glasses near production or already on the market include the following:
Oculus is the most famous Rift, eye-resolution 1280*800, it directly using two displays instead of optical lenses (using Samsung's AMOLED screen), self-453g, sells for $ 350 (about 2170), but it's still a developer-oriented products, and cumbersome to use.
Sony HMZ series, has had three successive generations, and are mainly used for 3D viewing. Latest HMZ T3 uses two 720P OlED display, offers 20 m watched 750-inch 3D giant-screen film effect, but charges at home, lack of sincerity by Cheng Hui 7999.
Samsung Gear VR virtual reality goggles, you need mobile phone as a display module, on December 1 in Korea launched, priced at about $ 187 (about 1122), currently there are only compatible with Samsung phones ... ...
The oldest Nintendo Virtual Boy, which is itself designed as a game host and already went on sale as early as 1995. But the price is $ 179 (about 1074), 384x224 resolution display can only provide 4-color and 32 shades of gray, the processor clock speed 20Mhz, well, read that right, it is 20Mhz ... ...
And it is most horrible Air VR, it displays, is actually the iPad mini ... ... Price 49 knife (about 300 or so), weight of the upgraded version of 150g. Fortunately, the iPad mini is only 308g, weight can only effect would be a bit strange.
Most Geek, Google was Cardboard, weight does not exceed 50g, lowest price 20 knives (120), but you can also completely by their own hand-made. If you do not mind if it cannot be fixed on your head, it's still pretty cool.
Technical problems and difficulties
Virtual reality glasses problem, there are several:
Processor: dual image display devices at the same time processing, but also for 3D processing, higher requirements on processors and optimized.
Heat and battery life: using glasses need to call more than one sensor, the display device is almost fully working, so heat is very considerable, not often. Mirror the recommended time is less than 30min, and Gear of the Samsung VR is 25min (it was ridicule these days work overheating problems in the process).
Resolution: as the naked eye and the distance is set very close to the screen, and at the same time providing eye view, resolution to only half, so a high PPI to eliminate screen grainy. Even the highest 2K phone screen says unable to. In addition, the 16:9 mobile phone screen will turn on them 8:9, seeing things'll be flat ... ...
3D source: 3D source has been the 3D device not open around the pain, and not all can display a 3D movie, or avatar will not become the legend.
Summary
Facing the same opponent, mirror of the storm does have an obvious cost advantages, 99 soft currency with a Bluetooth remote control, rather than breaking thousands of foreign products, and is very conscientious.
Its wearing comfort and operation flow is good, though not very practical at the moment of the game, 3D source is also relatively scarce. But even so, it is also a phone screen to enjoy an alternative form, usually the effect of watching a movie is better than holding a cell phone well. Unfortunately is that the remote control handle is now only used in the official Glen Johnson.
Final purchase proposal is that it does have practical value to chop his hands left the party with a low enough threshold of impulse buying. Want early adopters experience the virtual reality, or would like to use it as a "3D Theater" and is worth buying. Assuming, of course, is to get on the official website ... ...
