Lei feng's network (search for "Lei feng's network" public attention) by writer Jiang Jiayi, Department of mathematics of Peking University, Dr returnee, currently serving as light winds SLAM algorithm engineer. Obsession with games 20 collection has all of the consoles from the NES era.
AR Pokemon Go upon release of the game, brought a series of effects, crazy fans, paralyzing server crash police station, as well as shares of Nintendo soared.
Is this game can let the whole world crazy, except Pokemon itself top IP gene, AR element addition is the most important reason, is AR Pokemon Go reborn. michael kor
Unique AR games
What is AR? Global understanding AR Pokemon Go to play home, perhaps even to 1 per thousand, but what they have in this magical world there has been a wonderful experience.
AR games and hand out a space and time. Pokemon Go venture Niantic Labs CEO and founder John Hanke said: "this is a new experience, playing games and mixed in with other things you do. "
Links, this is the charm of the AR. Who provides the game must be quickly at a computer mouse and keyboard, or hold phone stamp to stamp, and it can also be another attitude. Lights had returned home, and on the floor is only better than kaqiu, a walk in the Park, appeared around the singing waves comparable and perhaps can go home while shopping pick one up to duck.
AR to join Elves into real life, Pokemon Go and other games also have essential differences, waiting patiently for a long time for tears.
Pokemon Go isn't perfect
AR, so back in Google's April Fool's joke after the video out, and started to watch the game. Video player over the mountains, and finally found a small dragon in a cave, with the phrase "Gocha! "He pleased smile. This is a joke, but Nintendo contacted Niantic, so the joke became reality.
From Google video, and then to the Niantic's official promotional video, as AR technology, I think the AR game at least will achieve the following results:
1, Elf and real-world integration, to show that actually exist in the real world. It needs three-dimensional reconstruction and recognition, Elf build on the natural plane, not some strange places.
2, the Player encounters the associated the elves and the surrounding environment, such as Lake will see water in the jungles of Elves instead of grass. Not only map service based on LBS class, but also to surrounding environment recognition using AR technology to achieve the integration of picture details. Michael Kors iPhone 5
3, the screen becomes a window on the players and the spirit world. This requires accurate player cell phone location, makes the players close to watch Elf, even interact according to the location, such as near the Elf ran away.
But the current demo experience, there are inevitably sellers show buyers and show differences. If the AR game is perfect, what kind of technical support? Brief analysis of the:
Structure of Cognition:
AR is the abbreviation of Augmented Reality and augmented reality. Augmented reality, we must first understand the reality. Perception of reality in AR technology is the most important part of understanding reality structure algorithm with offline and online for difference, called SFM (reconstruction) and SLAM (construction and real-time location map) algorithm. SFM method has become the standard in the construction of 3D maps of the algorithm, and SLAM algorithm for more application in the field of robotics, and began to play a role in the AR field in recent years.
Pokemon Go is a real-time combat game, so SLAM technology becomes key and preferred. SLAM technique in a variety of different sensors to cognitive players in real time scenario, based on real scenarios correspond to the 3D point clouds, through the analysis of 3D point clouds to understand the geometry of reality, such as where are the ground, desktop, and where is the wall. After you understand this information, can be in the right place to generate the correct virtual models, realistic scene mode allows players to interact with virtual models of the law.
Unfortunately, probably limited development time, or Nintendo wanted to test the waters first AR, the current version of Pokemon can Go right SLAM related technologies use less, so the Elves can often be seen in places non-planar, even floating in the air, seem endearingly. If you use scene recognition technology, the game more realistic. When players see the Elves from the ground jumped onto the table and then jump to his own bed moments will be very shocked.
In addition, the game needs to interact with reality, but players do not necessarily understand Elf generation algorithm, if generated at the edge of some high elves, the player might risk follow, causing unnecessary tragedies.
Semantic-based environment recognition:
And cognitive difference in value the geometry of the scene, semantic-based environment recognition more human way to meet real life scenarios. Scene is located in the city or in the country such as recognition, scene exists in the lawn or pool.
Thanks to the now hot deep learning algorithm over recognition has been achieved gradually, even beyond the accuracy of human cognition itself.
Though cameras provided images, image recognition algorithms can identify players as well as the natural landscape around the scene, so players could catch Bulbasaur in the grass, in the water to find Squirtle.
Semantic-based environment recognition can easily put the Elf's property and the surroundings in a meaningful way in which players are strung together, different scenarios correspond to a different story, and not just rely on LBS technology random and disorderly met different fairies on the map.
Show location:
Experienced Pokemon Go player should have found that when you wanted to own the House Elf "close to" a closer look at these cute when Elves remain, and the players maintained a "distance".
This is because Pokemon Go on algorithm use only a mobile phone comes with very rough positioning gyroscopes on the player, so when the player moves forward, does not experience the Elf "zoom" effect, originally stood on the table instead of Elves to stop "in the air".
Floating in the air of the House Elf
Wants to achieve a greater sense of substitution, on the need to enhance display and positioning technology of reality scene. First scene structure of cognitive, only by understanding the structure of reality, may be superimposed on the virtual model more realistic scenarios.
In gym challenge, for example, if the join algorithms of structural cognitive, players will see through the phone screen his house turned into a gym, namely a virtual gym on the structure of the model in the real world, such experience is clearly better.

Second, players in this like really like in the scene move to watch, also need to rely on precise positioning technology. Why do I have to locate it?
This is because the virtual scene position is based on an estimate of the player relative to the real world calculations projected onto the real world, ideal results is that players feel of virtual model is fixed in the real world, became part of the real world.
So if the player's location cannot be accurately estimated, players will see some deviation from the virtual model or scene that causes a "floating" endearingly.
Conversely, using precise positioning technology, players can close all details of the virtual objects, for example, I just always wanted to be close to sprouting Pikachu. Current mainstream positioning SLAM algorithms and VO classes (Visual odometry) algorithm.
Speech and gesture interaction:
I have fantasy Elves capture process is this: throw a fairy ball, while shouting "are you, Pikachu! "Capturing Pikachu will then sprout State appears on the screen in full – is God-like experience. It is a pity that so touching the screen now you can't back to Pokemon in the game of Go. At present, as the most important module in AR technology, voice and gesture interaction has reached a mature stage, want to achieve this effect is not an impossible dream. Join the speech recognition feature, players can call their favorite elves, can command them through voice interaction, like a real trainer. The other hand, if you substitute finger slide gesture recognition to manipulate Elf ball out and soothe the elves of pleasure will also increase.
AR glasses can make Pokemon Go better?
Of course, the above analysis and the imagination is not to illustrate Pokemon Go well enough, but proves, when technology and game development, game experience will be greatly optimized spaces.
In addition, the auxiliary equipment is another way of optimizing. In planning the games, Pokemon Go to the phone's limitations, so also launched the bracelet. Vibrates to remind bracelets appear in Elf, eliminating the player has trouble with the phone.
Bracelets + mobile phone may not be the best way. You can see from the above analysis, had wanted to see the scene, must be approved by the mobile phone screen you can see, interact will be confined for the touch screen, mobile era universal mobile phone has become a player and an invisible wall between the Elf. But if you have the glasses, this lack of experience can be made up.
AR glasses, allowing the player to have entered the spirit world. Cameras and sensors can perceive the environment, quickly remind players have goals around the House Elf appeared AR optical glasses, not only widens the screen dozens of times, has further deepened the degree of Elf in the real world into the virtual, as if they really is all around us; AR glasses to maximize free hands, running and jumping wall flip is not a problem.
Pokemon Go is the dream of a generation, childhood sustenance from TVs and game machines ran out, into a life of companionship. People who AR industry, and will give birth to an idea, wish I had the ability to this company is becoming more and more good, selfish hope other than Pokemon Go, home also to have such a good game.
