First of all, thanks to Lei Feng.com for giving me the opportunity to try out Xiaomi VR glasses. There have been reports about VR virtual reality before, and they started to think it was another way of 3D technology, especially to experience the experience effect brought by VR technology interaction. Before that, I had the honor to experience a brand of VR glasses (hereinafter referred to as X-VR glasses). The price is close to Xiaomi VR toy version. I generally feel that these two products are of the same standard, and will make corresponding comparisons in the subsequent use process.

Product arrival

The product packaging box is black, and there is a steel stamp marking millet logo right above the top. There is no color contrast in the black background. It is not obvious that the logo reflects light when changing the angle; The front is written with red font "Go to explore", which is the same theme as Xiaomi's annual brand video. To explore black technology, Xiaomi is born for fever; There is a incomplete sign in the upper left corner. Later, I saw the online friends' articles and found that it was“ Love to play computer games ”Logo of. On the back is the instructions for trying out Xiaomi VR glasses toy version. The device requires Android 4.4 and above, and the screen is 4.7-5.5 inches.

Unpacking is a letter from Xiaomi Exploration Laboratory, which feels like the task introduction before the game starts. Moreover, the VR glasses, which are black, weigh 204.4g, 203mm * 105mm * 94mm, are said to be made of spandex fiber (Lycra). I feel that they are hard to wear, not as comfortable as the medical silicone of VR glasses.

The front center of VR glasses is a striking orange millet logo with "VIRTUAL REALITY" written below The virtual reality is spelled in English, with 31mm * 65mm rectangular boxes on both sides and R5 chamfer. It is estimated that this design is for the slight movement and heat dissipation of the mobile phone. It feels that the large area porous design is better than this heat dissipation. In addition, when the mobile phone is actually placed, the heat generating area (camera area) in the back of the mobile phone actually covers about 3/5, which does not achieve the purpose of complete heat dissipation.

Disadvantages: The heating area of the mobile phone cannot be completely exposed to the air, which is not convenient for heat dissipation.

There are rectangular buckles on the top and both sides of the VR to fix the straps, and the buckles on both sides also have an oblique angle of about 25 degrees. They are fixed with the player's head. There is a key with a diameter of 16mm metal thread on the right side of the top. The force surface of this key is not very uniform. It feels that it is harder to press the key at 10-11 o'clock, and it is easy to press the key at 4-5 o'clock. It is estimated that the inside is the principle of a lever, Make the internal conductive silicone head protrude about 3mm and touch the mobile phone screen.

The back of VR glasses is the fitting model of the face (frontal bone, nasal bone, zygomatic bone), which is used together with the bandage. There is a lens with a diameter of 34mm in the center, the focal length of 64mm is not adjustable, and the surface is equipped with a blue plastic scratch resistant film.

Disadvantages: 1. The face fit is not very tight, easy to leak light from the side, and the contact face is hard.

2. The mirror surface has no removable and reusable dust-proof and scratch device.

VR glasses have double zipper openings, ordinary sewing process, and millet logo on the zipper. After being pulled open, a demonstration paper cover is placed with the appearance of the mobile phone. The paper cover is printed with the QR code of the millet VR app, the mobile phone placement legend and the requirements for the mobile phone parameters. The paper cover is provided with a T-shaped strap, 25mm wide and 360mm long in all directions, to help players fix their heads; Open the cover, which is attached with 102 * 66 * 6mm hard cotton to help fix the phone; The top of the glasses is a conductive silica gel head with a diameter of 11mm, and two symmetrical 1/4 original arcs are on both sides. At the end of the arc is a 1-2mm raised anti scratch and anti accidental touch pad. At the bottom is a 92mm * 7mm mobile phone placement pad. At the bottom of the center of the glasses is an arrow mark indicating the alignment with the center line of the mobile phone screen. After observing the fixation of the lens, it is clamped with clips in four directions, In this case, if the lens is worn or scratched, the lens can be replaced with tools.

Appearance and function comparison of similar products

1、 X-VR glasses are smaller than Xiaomi glasses in size and weight, which makes Xiaomi look a bit bulky.

2、 X-VR glasses face fitting medical silicone is better than Xiaomi's Lycra fabric, but X-VR glasses eye light is vulnerable to external light, which requires comparison to feel the difference in effect.

3、 X-VR glasses are better than Xiaomi VR glasses in terms of heat dissipation when the back of the phone is fully opened, but the zipper design of Xiaomi glasses is not as convenient for installing or exiting other APPs.

4、 The click of X-VR glasses is operated by hand through the gap between glasses. There is little difference between the two products when playing the video, but the game state is especially shooting. Xiaomi glasses are more convenient.

Specific function trial

Xiaomi VR app, Ant VR app and LeEco VR app were downloaded respectively. Because the basic principles of imaging of Xiaomi glasses and X-VR glasses are the same, resources are shared, and the difference lies in the imaging effect of the mirror. My glasses are not short-sighted. When I put them on, I can really bring a feeling of novelty and excitement. It's like being a guest in someone else's home. Furniture furnishings and decorations will appear with the head turning. After more trials, I summarize several problems. No matter which app, the film time is very short, and the longer one will be 4-5 minutes, generally 1-3 minutes. I feel that VR video is still in the experience stage, In addition, when the film is played, the imaging pixel is low, and the picture will be worse when the photographer moves, especially for roller coasters. In addition, the play will show discontinuous stutters, and three mobile phones will basically show stutters. Personally, the source quality is the biggest problem of VR at present.

As for the game, I experienced the Xiaomi APP VR Battlestar, and the shooting game is quite good in terms of experience effect, aiming at the head and shooting manually. However, there are problems such as low image quality, low level difficulty, single operation and less interaction. The game has passed 7 levels (9 levels in total) in 15 minutes, which is not difficult. At the same time, players who play more games are playing games with more interaction from online friends. It is difficult for such domestic stand-alone games to attract loyal players, and the overall feeling is that there is no sense of immersion. After all, glasses also rely on the phone's screen image quality, built-in gyroscope and video decoding ability. At the same time, the problem of mobile phone heating is quite prominent, which is no less than playing a 300M game.

For the game experience, we specially found the VR experience sample of Shadow Gun. Shadowgun is a third person shooting game produced by Czech MADFINGER. It is produced by Unity3D engine. With the amazing image expression on the four core Kal El processor platform, its biggest feature is that it is comparable to the image quality of PC and host, allowing players to enjoy the top 3D rendering level on the mobile end, Shadowgun shows advanced lighting effects and a finely rendered environment, which can be said to be the best shooting game on the Android platform at present.

Game Demo experience needs to cooperate with the handle to control the movement of the characters. In the opening perspective movement, the huge character sculpture perspective is very shocking, and fully experience the VR effect. During the movement, I specially observed the details of the floor, the flying flag, the smoke of the aircraft crash, the burning effect, the transparency of the overhead skylight, the gradual change of light, the light and shadow of the lake outside the window, and the flashing indicator light The green light of the water tank, the front game characters, etc., and the Xiaomi VR glasses can reflect the delicate detail processing. If they move too fast, the visual effect is strong, and some heads will be dizzy, too real. If the VR version of this game is released, it will be great.

summary

This toy version of Xiaomi VR glasses at a low price is bulky in appearance among similar products, with less scientific appearance; The processing of heat dissipation and facial fit is not satisfactory, but the product production and detail processing quality control are good. In terms of product experience, it can really bring people the initial VR perspective experience. It is an entry-level product, which is mainly limited by the quality of film source. At present, personal understanding is still in the rough experience stage. Interested players can experience the effect of this visual impact. To open a new world, Xiaomi needs black technology to lead players to explore.
