Interactive games with augmented reality. Part 1. Introductory.

Good day, dear readers! I propose together to create a number of topics-seminars, the information in which will be supplemented as we discuss the topic set in it. Let's get started.

The topic of augmented reality ( augmented reality , AR , I will often shorten it as DR , and sometimes I will use the term “augmented reality”), it has been touched on Habré more than once, but since the topic is very extensive, you can say a lot more about it , despite the fact that I wanted to start writing about it back in 2008.
First, I will try to compose the available information. Also, in the first parts, I would like to speculate about the possibility of using real-time DR for interactive entertainment, including games, solving some practical problems, as well as for orientation both in the city and in nature, including including rugged and wooded areas. If everything goes smoothly, we get to practice.

In the water part, I will try to explain some terms that are important for understanding what DR is all the same, and I will also bring to the public some of my personal judgments, which are perhaps very controversial. Here, some issues related to pattern recognition and equipment will be partially addressed. We’ll also try to figure out what DR is like now and try to imagine how these technologies can develop in the future.

Today it is difficult to imagine a habuman, even remotely not having a clue about what Augmented Reality is. But, unfortunately, for many it is seen simply as an additional function in mobile devices, which helps to have fun, imposing some effects on the image received from the camera of this device itself. As a rule, everything is limited to simple “toys” with the replacement of one object (say, a sheet of paper with some design) with another and, possibly, even with some very limited interactive experience. In the best cases, the first object will be, for example, the wall of the building, when you focus on it, the marks left by other people will be displayed, which can be useful when navigating. We will not dwell on this in more detail now, so as not to repeat the material of articles that are already on this resource. However,

So, augmented, or augmented reality is a general term that refers to projects related to the addition of the visible three-dimensional reality to us with some virtual two-dimensional and three-dimensional objects and elements. Often these objects are, for example, text tips describing objects around us (kind of shortcuts) or other useful and not very information (name of the current composition in your headphones, real-time exchange rate changes, contextual advertising of diapers when you pass by the baby store). Less commonly, interactive virtual objects (we will get to them too).

Most often, we can see DRs in the form of applications for mobile devices, such as smartphones and tablets, which supplement the image received through the camera with some information, according to the functions, algorithms and capabilities embedded in the software (hereinafter referred to as the software). Increasingly, the elements of DR appear in product presentations and at exhibitions.
For example, the work of “AR Studio” from EligoVision during the presentation of the Olympic University is indicative.

... By the way, I propose to invite children to the Habra Club, otherwise officially, as I see, they are not represented here.
Another video on the topic, already recording the broadcast

If we trace the development of DR in the civilian sphere to this day, then we can understand what awaits us in the near future. I see at least three things that cannot be ignored, since sooner or later they can affect us all:
1) Augmented reality technologies smoothly move in the direction of augmented virtuality, when already virtual reality is supplemented by objects from real reality. At some point, it may turn out that we will cease to perceive reality in isolation from virtual additions to it. This, of course, is far away, but only by the standards of the pace of technological development.
2) Augmented reality becomes more interactive, which opens up new perspectives for it and gives it the opportunity to “integrate” into many aspects of our lives, in addition to the existing ones - navigation, games, entertainment, training, medicine and others.
3) With the development of technology, augmented reality is becoming more accessible to the average person.

Today, almost everyone can join the DR using their computer, tablet or smartphone, and at the same time - for free. And those who want to join in a more sophisticated way can already create their simple glasses and helmets of augmented reality, without spending thousands of dollars on it. Topics on Habr already were, therefore I will not repeat, if not asked.
That is, in the simplest case, we need to have three things that are already on any smartphone:
1) A camera that will capture the environment, recording an image from the reality surrounding us.
2) A hardware-software complex that will take an image from the camera, modify and supplement it, according to the algorithms laid down in the software and display on ...
3) A screen capable of visualizing processed information.

What we should be most interested in is the second point, since with the other two everything is already more than clear (in the context of this part of the article)

The power of even the simplest modern smartphones, tablets and, moreover, computers is already quite sufficient to process the video stream received from the HD camera in real time and supplement it with simple elements, such as marks, pictures, geometric shapes and low-poly 3D models, and in some In cases - beyond recognition, change the whole scene surrounding you, displaying the resulting information on the screen of your device, TV or sending, say, in the form of a video broadcast, to your page on the Internet, helping, in theory, go to augmented reality to all its visitors.

The situation with the software is somewhat more complicated: Affordable, simple and understandable DR programs are now catastrophically small and they are mainly oriented, by no means, to the average user. But the situation is changing rapidly and, most likely, already next year everyone will be able to “surprise” their friends with the virtual zoo created by him in his yard, pointing his eyes at the tablet’s camera in the sandbox with children.

This is the introduction. Waiting for your comments and additions. We will jointly form the following parts.

PS I apologize for the possible and, most likely, lexical, grammatical and other errors that take place, and I also ask you to report them in a personal message or to use the extension previously advertised for your browser more than once.
PPS Thank youGeorge Mashkovtsev u ( ) for a photo with monkeys. And many thanks for an invite on Habr to all involved in it.
