Preferences for VR/AR HMD

Posted on by

For VR HMD I prefer to choose the Oculus Quest all-in-one VR gaming headset. This one sells $399 on Amazon.

Advantages:

Screen:

Oculus Quest uses a monocular 1600 x 1400 OLED screen, although there is a sense of pixels, the pixel sense is not obvious, and it can be ignored when playing games because games are not required much for 3D graphics.

Lens:

Oculus Quest uses a Fresnel lens which advantage is that it provides clear experience for surroundings and there is almost no dispersion in the center or the surroundings, while blur and distortion will appear around ordinary lenses.

Controller:

There are two ways to use Oculus Quest. One is suitable for standing or sitting in place. It will let you set up a virtual wall with a diameter range of more than one meter. A blue grid will appear around you in the game. When you do not exceed this area It will not be displayed when it is exceeded, it will be warned after it is exceeded, and an external screen will be displayed, but the colors are processed. Another way is to use touch to mark a moving range. This range can be relatively large, such as two or three meters in diameter. You can draw a range around the wall around the room. As long as your body does not exceed this area, no warning will appear.

In some games, the touch controller will become its own hands. It is quite unexpected that the controller can almost represent various gestures of people, including raising the thumb can be perceived, and feedback in the game. Some picking movements can be done easily, even with a slight hallucination that which is your own hand.

Game:

Oculus Quest is the most suitable one for playing games, and can even be directly positioned as a game console. It has a perfect game experience for playing Rhythm Space that the music and lightsaber are perfectly matched with the vibration feedback. Some roller coasters and horror games are suitable for people to play when there are many people as they can activate the atmosphere and bring joy to relatives and friends.

Disadvantages:

The angle of view of Oculus Quest is about 100 degrees which is worse than Vive. Fresnel has a disadvantage that is its clear central area is small, and it is necessary to carefully adjust the interpupillary distance and up and down position so that the eye is located in the central area of the lens, otherwise, it will be very unclear. Therefore, VR devices with Fresnel lenses without interpupillary distance adjustment may not be suitable for some people. The battery is not durable and can last for only about two hours or more. The effect of the built-in headphones is average, with 3.5mm ports on both sides, but the cable is easy to interfere with after connecting the headphones. Due to the limitations of resolution and FOV, Oculus Quest is not very suitable for watching videoes.

In general, Quest is still the main game but not suitable for watching videoes. It is the main product of Oculus at present. Because PC VR is too expensive to get started, many people ’s home PCs have not been updated for many years. If the price of a complete set is too high, it will block mainstream users. Quest this all-in-one machine should be the main development direction, at least in the mainstream public domain. The wireless of VR is inevitable. After the popularization of 5G in the future, an all-in-one machine such as quest can put a lot of processing pressure on the cloud server. This wireless is also the most effective for resource utilization. And wireless like PC VR, just remove the cable, still need to set a high-performance PC at home, this PC is only working when you play VR games, the rest of the time this PC It is in a state of idleness and waste. This method has performance advantages in a certain period of time, but it is destined to be difficult to radiate to mainstream users. To make VR as popular as smartphones, Quest is taking an inevitable path.

For AR/MR I prefer HoloLens 2.

Compared with the parameters of the first generation, it can be seen that the field of view of the Hololens 2 has more than doubled compared to the first generation, and the resolution has increased from 720p to 2k, and the sharpness has been greatly improved. The holographic scene brought to users is more vivid, more realistic, and more immersive.

And Hololens 2 has a better understanding of the environment and support for gesture interaction. This means that when we use it, it will be more convenient to operate.

Prior to this, the Hololens generation has always been criticized that the device is heavy, and it will compress the bridge of the nose when used, and it cannot be worn for a long time. The second generation has added a new function-a sunshade can be lifted up, and cushions are designed on the front and back of the head, which greatly improves the wearing comfort, which is not only very convenient to wear but also solves the problem of pressing the bridge of the nose.

Hololens2 enjoys a two-year commitment to quality assurance and obviously has improved in after-sales service.

In summary, the second generation has comprehensively improved in terms of performance, comfort, and cost performance.

MECHANICS

It uses dual system mode that players can choose either instance combat system mode or round combat system mode, and designs a variety of systems to increase the playability.

There are three different levels of difficulty in the game for players to choose: simple, normal, and difficult. It is impossible to choose the difficult level at the first time before all major missions are finished. At the same time, the game also provides the “difficulty down” function: players who feel excessive pressure in the game can downgrade the difficulty of the game, but once the difficulty is lowered, it will not be able to recover, and can not challenge the difficult difficulty of the BOSS.

STORY

 
The story is based on Chinese ancient legend. When the Shennong God was born, the world was accompanied by Jiuquan. Jiuquan’s various abilities are the source of the world. In the ancient time, there was a war among three races: Human, God and Orc, ended up with Beast losing. Chiyou introduced the orc into the devil world, and the three realms were separated. After the war, Shennong and Jiuquan disappeared. As time passed, the legend of Jiuquan was gradually forgotten.

AESTHETICS

The scenes are vast and the players can enjoy all kinds of customs in the game, such as the mysterious flying city, the border scenery of the exotic people and the sunset scene of the west wind, or the fantasy field of deep sea and the sky. In addition, the production team added a whether system that can change day and night to the scene. In the game, scenes and characters will change over time. When the character stays at a certain place, it will obviously feel the sun’s rise and fall, and the time will slowly pass. The clouds in the sky have passed and changed, and the whole world in the game has become more real. In addition to day and night changes, there are also more weather performances: rain, lightning, sand, leaves, mist and so on.

The dubbing team is professional and top-level. Players will hear the most popular star of the domestic dubbing.

  • RAM: 4G
  • Operating System: Windows XP / win7 32bits / win7 64bits / Win8 32bits / Win8 64bits (Chinese version)
  • Harware: 16G

Lens #1: Essential Experience

This game is beyond life, because the story and background in it as well as the skills of the characters, are not realistic, therefore normal people cannot experience. It provides players a different experience that allow players to immerse with the adventure, feeling themselves experience all those things. It is like a movie, or a book, in all is an new experience for players.

 

Lens #2: Surprise

This game has a variety of small games and mission events throughout the game world, such as new puzzles and institutions that require the skills unique to each protagonist to match the map. After help them and finish small task successfully, there will be unexpected surprises. As this in-game exploration is more free than the previous generations, players will find more hidden characters and events in the game, and may encounter various hidden “picking items”

Lens #4: Curiosity

In this game, there is a system called Spirit System, through which the player can choose different training directions for the character, so that it has more powerful ability and the character characteristics are more vivid. Each character has its own unique three souls. The growth attributes of the three souls are different. The value of each node is different. The player will be able to select different soul nodes to light up according to the prompts. There are some properties to be activated hidden in each soul. When enough nodes are activated, the hidden property nodes will be automatically opened, bringing more different training directions. Players will stay curious about what characteristics they finally make for the character.

Lens #6: Problem Solving

Each of the six protagonists has a unique “scene skill.” There are a lot of well-conceived organs in the game that players need to make good use of the six-player scene skills to pass. Yue JinZhao has used the “Flying Sword”, which can let him leap some obstacles or reach some places that can’t be reached. Yue Qi has the ability to “move things by mind” which can move the controllable items to anywhere you need. By analogy, other people’s scene skills are also so convenient and interesting. Players should try to use these skills to solve the problems. If Players cannot think of the solution to pass the current stage, they can try changing character.
