Augmented Reality Games on personal information systems like smart phones are on the rise. Smart phones games are usually easy to play and they can be played almost everywhere and at every time. One of the first mobile AR game was “ARQuake” , a first-person PC shooter game, created in the year 2000 . The game allows the player to walk around in the real world while he plays a game in a computer generated environment. To play the game the player need a GPS system, a standard laptop on a backpack with GPS tracker and orientation sensors and ad least a custom made gun controller .
Perhaps the first augmented reality smart phone game called AR Soccer. The game was available in 2004 and the player has to kick a virtual ball with his real foot into the virtual goal . A game with the name AR Soccer is still available in the today’s app stores (iOS, Android), but it seems that it has not the same kind of game content like the very first version. In the same year, the first multi-user augmented reality game called “Invisible Train” was presented. In that game, players controls virtual trains on real wooden miniature railroad tracks. With their PDA’s, which are connected over Wi-Fi, they saw and steered the virtual trains .
Combine virtual games with the real world
The major advantages by playing games on mobile devices like smart phones are whose mobility. They can be played anywhere; they can combine the real world with virtual elements. Augmented reality games are not restricted on a TV or PC screen and they can offer a better user experience . Below there are introduced some different kind of up-to-date augmented reality games.
Massively Multiplayer Game: Ingress
Ingress (iOS, Android) is an augmented-reality massively multiplayer online location-based game . The playing field is the world himself. The Ingress Game was developed by Niantic Labs from Google. The first in 2012 released version was only for Android devices, but since mid-2014 it is also in the iTunes App Store available. In the game, the player has to find and to capture “portals”. These portals are real world places like landmarks, monuments, buildings and so on. The player has to go close to these portals, at most only 40 meters away. When the player captured a portal, he can link portals together and earns in that way points for him and his fraction. The other fraction, there are two fractions, the ” Enlightened” and the ” Resistance”, tries to get the portals back. In that way, the player has to walk around, find the portals, capture or defend it, alone or together with other players .
The business model of the Ingress game depends on the one hand on an in-game store, where the players can buy special game items with real money. On the other hand, companies can pay for portals at their location or in-game equipment. These portals or game equipment wear then a company logo and/or the name of the company .
Game Apps for Education
Augmented reality apps could give a hand to learn things better. It is possible to enrich texts with supplementary multimedia information like movies, images or links to further knowledge sources. For that, papers and books can contain “markers” that, when scanned with an app on a smart phone or a tablet, shows this additional information . An example of such an app for tablets is the i-Wow Atlas World (iOS, Android). With this app, children get easy additional and fascinating facts to our planet when the scan a globe with the app.
Another example is the app smart phone and tablet app “Quiver” (iOS, Android): With “Quiver” children colors plain pictures of for example animals and with the app they can see the animal in 3D. Children gets with these apps an idea how the animals are living in the real world. The pictures to color for must be purchased, the app himself is free. Without these pictures, the app does not work. An example how it works is demonstrated in the video below.
Another application are simulations which helps to understand things better . A famous and well known kind of simulation and educational app is “SkyView” (iOS, Android). This app helps to spots objects on the sky like stars, galaxies, constellations and other additional facts about astronomy. Apps like this are normally not free to use or includes some advertisings.
Such educational apps can help parents and teachers to help children to learn things easier and in more than one way. The children not only read the facts about a topic, they can also see the objects in 3D and they can play with it. To learn something with the assistance of augmented content is named “Augmented Learning” or “E-Learning” .
Funny pastime games: Virtual Basketball an Bowmaster AR
Finally, there are also other games for the pastime available. These kind of games usually are not free to play. Either the cost something in the app store or the contains some advertisements.
Virtual Basketball (iOS): For that game, the player need to printout a small marker. To play the game, the smart phone’s camera has to point at that marker and a virtual basketball basket is shown up. Now the player can throw basketballs into the basket to get points. This game is a funny implementation of augmented reality and a very good example of the technology.
Bowmaster Augmented Reality (iOS): The game needs also a printed marker and it works similar to the Virtual Basketball game. Instead of throw balls, in that game the player has to shoot arrows to different targets.
