How does tracking work in augmented reality

In today's world, technological change is becoming more and more rapid. Of Virtual reality glasses to 360 degree videos There are numerous use cases that entertain people, but also offer added value to make everyday life easier. A current trend and is currently the most popular system Augmented reality. But what exactly is AR?

Definition: what is augmented reality (AR)?

The term "Augmented Reality" comes from English and can translated into German as augmented reality become. This expansion of the perception of reality is computer-assisted. she is a Part of mixed reality. With AR, it works differently than with Virtual Reality (VR), not about putting yourself completely in a virtual reality, but about the To supplement “real” reality with additional elements. AR can be related to all human senses, but mainly refers to the visual representation.

Examples of augmented reality

We already encounter the use of augmented reality in sport. AR is used in sportsto show, for example, lines showing offside or goal distance.

Among the most famous missions of the mobile augmented reality currently count the apps "Pokemon Go" and "Snapchat”. A novelty from 2017 is the AR app Ikea Place, which enables the user to virtually place Ikea furniture in original size in their own living space.

Google Glass was also implemented via augmented reality. The AR glasses link real objects with information and displays it. With the help of AR glasses fitters can leaf through operating instructions while they are working on the machine.

The Use AR technology effectively. In healthcare, the use of AR can make the work of doctors easier.

The RECARO AR app

Bitfactory implements the new Augmented Reality App for RECARO eGaming. The RECARO AR app makes it possible to visualize different model variants of the gaming seats in your own four walls in 3D. The gaming chair can be used in original size in your own living room via the AR app virtually placed become. This gives the user a first impression of the product in the real world.

History: How has AR developed?

Augmented Reality (AR) has its technical Origin in the HUDs (Head up Display), which were originally developed for the fighter aircraft in the 1950s. Even today, HUDs are used in the military. They are integrated in the helmet visors and equipped with AR functions.

As indispensable for the development of AR technology applies to the conference International Symposium on Mixed and Augmented Reality (ISMAR)which first took place in 2002. The symposium takes place annually alternately in Europe, Asia and the USA.

Market studies show that behind the AR trend hides a great market potential and with one Market breakthrough in the next few years can be expected. Due to the possibility of using AR regardless of location and integrating it easily, there are many different fields of activity for the user. According to the editors of Forbes magazine, augmented reality has the potential to create a whole new market.

How does augmented reality work?

AR browser

AR browser are existing platforms provided by third parties that make the simple Create and edit AR content enable via developer tools. The AR browsers are mostly supported by the iOS and Android operating systems and used via mobile devices such as smartphones and tablets. AR platforms are based on the Functionality “Location based service” (LBS) or on the image and marker recognition.

AR apps

In contrast to the AR browser, the AR app a individual and innovative solution for a Augmented Reality Experience, which are based on basic technologies such as the Apple ARKit. They can be used by the user in the areas of information, entertainment, edutainment (education & entertainment), etc. Possible Display formats for AR applications are: simple text overlays, embedded video and audio files, 360 ° panorama and turn-around displays, animated 2D and 3D content. AR apps show the user additional information about their location using the "Local based service" (LBS), or fade in virtual objects in the screen display of the real environment, using image and marker recognition.

AR functionality

There are two different modes of operation of the augmented reality browser and the AR apps. Some systems only support one, while others support both:

Location based service

With the LBS, the location-based service, all important and necessary information about the location of the user is drawn. This is done via the activated GPS on the end device. An internet connection is required.

Image and marker recognition

With marker and image recognition, certain objects are used as reference points for the AR. The analysis of the camera movement to the real world is called tracking. Tracking is most easily controlled using markers that are 2 or 3 dimensional. For example, a book page or a beverage can can be used as a marker. It is important that the markers have contrasts and sharp edges so that the program is able to recognize them.

Augmented Reality application

Example: ARKit development platform

ARKit is the Apple development platform for mobile iOS devices. It was introduced in 2017 along with the 11th version of the operating system (iOS 11). ARKit performs while moving the device "Environment mapping" by. The prerequisite for this are integrated features of the Apple device such as camera, acceleration sensors, gyroscope and context recognition. Apple's software uses the platform to incorporate the functionality of 2D and 3D elements into a live preview. ARKit combines motion tracking, image capture, advanced scene processing and convenient display use in one interface. For example, are created AR scenes persistent and can be seen by those visiting the site at any time. The user of the AR applications requires an Apple device with an A9 processor to support the system.

Requirements for using AR

In order for augmented reality to work on the device, the following requirements must be met:

  • Content and application software.
  • Camera for image acquisition and processing.
  • Presentation hardware (display).
  • Marker for tracking (when using image and marker recognition).
  • GPS (when using the LBS).

Note: Augmented Reality requires particularly high computing power and a good smartphone camera. Because of this, are AR appsCompatible with new iOS and Android models only. Older models are not ARKit compatible.

Conclusion

The popular Technology augmented reality brings many great possibilities with it. Many functions are already integrated in everyday life for media-savvy users. The AR applications can be found in the areas of gaming, communication, sports, e-commerce but also in the healthcare sector. AR will experience a huge growth spurt within the next few years and be represented in almost all industries. We are excited to see what novelties in the area of ​​AR are coming!
