What is Augmented Reality?

Augmented Reality (AR) is a technology that integrates digital content into the real world, thereby creating new, interactive experiences. Unlike Virtual Reality (VR), which creates a completely virtual environment, AR enhances physical reality with virtual elements such as images, text, or animation. Whether in advertising, gaming, or online shopping, AR has now become a part of many areas of our daily lives and opens up entirely new possibilities for companies to reach their target audiences.

In this article, we explain what Augmented Reality is, how it works, and show practical examples as well as an outlook on future developments.

What is Augmented Reality?

Augmented Reality, in German „erweiterte Realität,“ describes the merging of the real and digital worlds. In this process, virtual content—such as 3D models, animations, or information—is overlaid onto the physical environment in real-time through cameras or displays.

Historical Overview

The origins of Augmented Reality date back to the 1960s with the development of early, simple systems. The first commercial use occurred in the 1990s when AR was utilized in television broadcasts to provide additional information during sporting events. With the widespread adoption of smartphones, which are equipped with high-performance cameras and sensors, AR is now easily accessible and is used in a wide variety of applications.

Differences between VR and MR:

• Virtual Reality (VR): Complete immersion in a virtual world, e.g., through VR headsets.
• Augmented Reality (AR): Augments the real world with digital elements.
• Mixed Reality (MR): Combines AR and VR, where the digital and real worlds interact with each other.

With AR, users can therefore continue to see their surroundings while they are augmented with virtual content – a big advantage over VR, which completely replaces the real world.

How does Augmented Reality work?

Augmenting reality with virtual elements is not so easy. It requires devices that can recognize movements and perceive the environment. Furthermore, they must be able to represent the augmentation convincingly. All of this must happen in real-time and without any delay discernible to the user.

Augmented Reality Hardware

The hardware components for Augmented Reality (AR) are crucial for the user experience. The most important devices include AR glasses, smartphones, and tablets. AR glasses offer the benefits of a hands-free experience and deeper integration into daily life.

There are various AR glasses on the market, including the Microsoft HoloLens, Magic Leap One, and Vuzix Blade. These glasses are designed for different applications, from entertainment to professional and industrial uses. The Microsoft HoloLens, for example, is particularly suitable for industrial use as it offers features like mixed reality and remote assistance.

The cost of AR glasses varies greatly depending on the model and features. Simple models like the Vuzix Blade can be around 800 Euros, while high-end models like the Microsoft HoloLens 2 can cost several thousand Euros. It is worth noting that the Microsoft HoloLens, a former leader in the AR glasses industry, is no longer in production.

The Meta Quest 3 is primarily a VR headset, but it also supports some AR features. It is not specifically designed as an AR headset, but its cameras and sensors offer the capability to experience augmented reality.

In addition to glasses specifically developed for AR, there are also devices like the Meta Quest 3. It is primarily a VR headset, but it also supports some AR features. This combination allows users to have both virtual and augmented reality experiences, opening up new application possibilities.

However, one advantage of mixed reality glasses is the price. The passthrough technology makes these glasses much cheaper than high-end models like the Magic Leap One.

Technologies behind AR

• Tracking Technologies Enabling the location of digital content in the real world. Examples include SLAM (Simultaneous Localization and Mapping) and GPS tracking.
• AR Software Tools like ARKit (Apple) and ARCore (Google) support developers in creating AR experiences.
• Render Engines Unity and Unreal Engine are used to design and render 3D elements in real-time.

Augmented Reality as an App vs. WebAR via the Browser

AR with an app and Web AR are two ways to experience augmented reality content on mobile devices. Using augmented reality apps requires downloading and installing a special app on the device, while web AR can be accessed through a browser.

The use of AR by an app typically provides a better and more immersive augmented reality experience because the app is tailored to the specific device and its capabilities. The app can also access the device's collected data such as GPS, camera, accelerometer, and more to create a more comprehensive AR experience.

On the other hand, Web AR offers the advantage that it does not require the installation of a special app, making it more accessible. Web AR can also be launched directly from a website, making it easier for marketers or developers to create and share AR content.

AR Frameworks

There are a variety of AR frameworks that help developers create and implement AR content. The cost of AR frameworks can vary depending on the framework, licensing model, and project requirements. Some AR frameworks are free and open-source, while other frameworks require licensing fees or subscription fees.

Here are some popular AR frameworks:

• ARKitA framework of Apple, which is integrated into iOS devices and allows developers to create AR content using the device's camera, gyroscope, and accelerometer. ARKit is Apple's free AR framework. ARKit provides features such as horizontal and vertical surface detection, face detection, positioning AR objects in the real world, and interacting with AR objects through gestures. ARKit also offers a variety of tools and resources to help developers create AR content, including ARKit developer documentation, sample code, and an active developer community.
• ARCoreA framework from Google that runs on Android devices and creates AR content using the device's camera, gyroscope, and accelerometer. ARCore is quite similar to ARKit in terms of features. However, Apple's framework delivers slightly better tracking due to the superior sensors in Apple devices.
• VuforiaAn AR framework that runs on a variety of platforms and allows developers to create AR content with camera and image recognition. Vuforia offers a free version with limited features and several paid versions with advanced features and support.
• Unity AR FoundationAn AR framework that is Unity Engine-based and enables developers to create AR content for iOS and Android devices. Unity AR Foundation is part of the Unity Engine, which offers paid licenses and subscriptions.
• WikitudeA framework that runs on a variety of platforms and allows developers to create AR content using the camera and image recognition. Wikitude offers a free version with limited features and various paid versions with advanced features and support.

WebAR Frameworks

There are also frameworks that on WebAR specialized

•  Google Model ViewerGoogle Model Viewer is a free web tool from Google that allows users to view 3D models in a AR or VR-to display the environment. The tool is easy to use and supports a variety of 3D model file formats. The framework is free.
• 8th WallWith 8th Wall, developers can create AR experiences in web and mobile applications that run on iOS and Android devices. The framework offers a variety of features, including hand and face tracking, room and environmental understanding, and integrations with other tools and platforms. Developers can also embed 3D models, images, and videos into their AR experiences and program them using Javascript and HTML5. 8th Wall is technologically the most advanced WebAR framework, but also the most expensive.
• ZapWorks The ZapWorks Editor Toolkit offers a variety of features, including interactive 3D models, augmented reality effects, and animation tools. Developers can also create their own custom scripts and embed them into their AR experiences. ZapWorks is a powerful tool that offers users a variety of options and features. ZapWorks has its own 3D engine. Nevertheless, you can also use content from other WebGL Transforming and embedding engines like AR SDKs for Three.js, Unity, A-Frame, PlayCanvas, Babylon.js, JavaScript, and React-Three.js into WebAR experiences with Zapworks.
