Stronger sense of reality? Decrypt the hot AR game
Recently, Nintendo released an AR game called Pokemon Go. Once the game is released, it brings countless serial effects, crazy fans, and awkward servers. So what is AR? How does it make players crazy?
Silly and unclear? Recognize VR and AR
Speaking of the current popular VR, many friends may not be unfamiliar, but AR may not be understood by many people. VR (Virtual Reality) is a popular virtual technology. It uses computer simulation to generate a virtual world in three-dimensional space, providing users with simulations of visual, auditory, tactile and other senses, so that users can have Real virtual reality feeling. AR (Augmented Reality) is to apply virtual information to the real world. It superimposes the real environment and virtual objects into the same picture or space at the same time, and can obtain a more perfect interactive experience. So what is the difference between the two?
The scenes and characters seen in VR are all virtual. It just substitutes your consciousness into a virtual world through VR devices, deceiving the brain to "misunderstand" that you are in a real scene, the main emphasis is "substitute sense". Therefore, VR devices are often immersed, and the typical device is the Oculus Rift. The scenes and characters that AR sees are partly true and false. They bring virtual information into the real world. The highlight is the "reality", which focuses on the connection between virtual and reality, in order to achieve more shocking Reality enhances the experience. For example, Nintendo released the AR game Pokemon Go, which made many players completely addicted and completely immersed in the game world (Figure 1).
Augmented Reality? How does AR get a better gaming experience?
As mentioned above, AR is an augmented reality that can achieve a more realistic reality and better interaction than VR. So how is this enhanced virtual reality effect achieved? Take Nintendo's release of the AR game Pokemon Go as an example.
First of all, let's take a look at the basic gameplay of this game. According to the game introduction, after opening the game on the mobile phone and opening Google Maps and positioning function, the game will superimpose Pikachu, Jenny Turtle and other elves in the real-time camera. These elves may be hidden in any corner of the current map, and the player needs to walk around with the phone, find it and grab it. In this AR game, the developer superimposed the virtual game elements Pikachu, Jenny Turtle and other elves into the real geographical location, allowing players to find virtual game characters in the real environment, greatly enhancing the game fun (Figure 2) .

From its technical means and manifestations, AR can be roughly divided into two categories. One is LBS based AR, which is AR based on geographical location information. The second is Vision based AR, which is based on computer vision.
The Pokemon Go game belongs to the former. When we turn on the GPS on the mobile phone, the game will obtain the user's geographic location through GPS, and then obtain the POI information (including name, category, longitude latitude, near the user's current location) according to the information provided by Google Maps. Information about nearby hotels, restaurants, shops, etc.). After obtaining this information, the Pokemon Go server will superimpose the virtual sprite in the game to a certain corner of the current location. If it is a certain stone, a certain lawn, the game player will take the mobile phone according to the current actual geographical location. Find hidden elves. This is like a hide-and-seek game in real life. Pokemon Go seamlessly blends the virtual scene and the real environment in the original mobile phone, greatly enhancing the fun of the game (Figure 3).

Another computer-based AR, which uses computer vision to establish a mapping between the real world and the screen, so that the graphics or 3D models we want to draw can be displayed on the screen as if they were attached to a real object. Its principle is similar to that of the former, and it also superimposes the virtual characters seamlessly into the current actual position. For example, Li Yuchun performed "蜀绣" in the Spring Festival Evening of the Year of the Sheep, and Li Yuchun appeared on the stage at the same time. One of them is the virtual Li Yuchun. The producers performed the same performance with the real Li Yuchun through AR technology, almost reaching the point of realism. "蜀绣" is actually a form of AR based on computer vision (Figure 4).

Not only games, AR is also used in these areas.
Through the above description, we recognize the outstanding performance of AR in the field of games and performances. In fact, not only in these areas, with the continuous development of AR technology, AR can be used to serve us in many aspects of life. As a new generation of human-computer interaction, AR has also been applied to many fields.
For example, in the field of tourism, AR can combine tourist attractions maps with tourists. In the ancient city of Zhoucun, Zibo, Shandong, using Lenovo New Glass glasses developed based on AR technology, after the tourists wear this product, the original ordinary building “lives over†will automatically use the graphic and even video to these fans. Tell the relevant allusions and sources. In the real estate field, VR technology can “transfer†buyers from different places to the house they want to buy, so that buyers can easily realize remote viewing, and feel the house and the surrounding environment that you need to buy in a near-real sense. Of course, in the field of online shopping, AR can also shine a lot. If you want to buy clothes, jewelry, and the like in the future, you can wear these things on your body or wear them through AR. This shopping experience is Isn't it more exciting?
Undoubtedly, with the development of technology, AR will gradually become the mainstream way of human-computer interaction in the whole society. We can bring more convenience and operation experience to our study, work and life through AR, and achieve better human-computer interaction by means of the fusion of artificial intelligence and big data.
