What is Augmented Reality?
Augmented reality (AR) is an experience where designers enhance parts of users’ physical world with computer-generated input. Designers create inputs—ranging from sound to video, to graphics to GPS overlays and more—in digital content which responds in real time to changes in the user’s environment, typically movement.
See the differences between Augmented, Virtual and Mixed Reality here.
AR’s Place in the World of Extended Reality
Augmented reality has science-fiction roots dating to 1901. However, Thomas Caudell described the term as a technology only in 1990 while designing to help Boeing workers visualize intricate aircraft systems. A major advance came in 1992 with Louis Rosenberg’s complex Virtual Fixtures AR system for the US Air Force. AR releases followed in the consumer world, most notably the ARQuake game (2000) and the design tool ARToolkit (2009). The 2010s witnessed a technological explosion—for example, with Microsoft’s HoloLens in 2015—that stretched beyond AR in the classical sense, while AR software itself became increasingly sophisticated, popular and affordable.
Under the umbrella term extended reality (XR), AR differs from virtual reality (VR) and mixed reality (MR). Some confusion exists, notably between AR and MR. Especially amid the 2020s’ technology boom, considerable debate continues about what each term covers. In user experience (UX) design, you have:
- AR—You design for digital elements to appear over real-world views, sometimes with limited interactivity between them, often via smartphones. Examples include Apple’s ARKit and Android’s ARCore (developer kits), the Pokémon Go game.
- VR—You design immersive experiences that isolate users from the real world, typically via headset devices. Examples include PSVR for gaming, Oculus and Google Cardboard, where users can explore, e.g., Stonehenge using headset-mounted smartphones.
- MR—You design to combine AR and VR elements so digital objects can interact with the real world; therefore, you design elements that are anchored to a real environment. Examples include Magic Leap and HoloLens, which users can use, e.g., to learn more directly how to fix items.
Partly because of the slight overlap regarding interactivity, brands sometimes use AR interchangeably with MR. “Augmented reality” remains popular—despite the point that the original sense of AR design is overlaying digital elements upon real-world views: e.g., GPS filters/overlays on smartphone screens so users can find directions from street views. So, digital elements are merely superimposed on real-world views, not anchored directly to them: The computer-generated content can’t interact with the real-world elements users see—unlike in MR. The HoloLens is MR, for instance, because it interprets the space in a room and combines digital objects with the user’s physical environment.
AR’s Expanding Appeal and Potential
AR designers made huge strides in the 2010s—a decade full of invaluable AR lessons and examples while the required sensors became cheaper. Pokémon GO is noteworthy, a GPS-oriented app that “inserts” Pokémon characters into users’ environments so users can find and capture them on device screens. Google’s AR stickers are another prime example; users drop realistic images into their camera shots. Users find AR particularly appealing for its entertainment value. Still, AR’s mainstream future appears assured across a wide range of applications, including education inside museums. With AR applications, you can bring experiences closer to users in their own environments through designs that are more directly engaging, personalized and—indeed—fun.

How to Take Digitalized Steps in the Analogue World
You have numerous design considerations, namely:
- Safety—Remember users’ real-world contexts; don’t distract/mislead them into danger.
- Overkill—Beware of drowning users’ senses with meaningless data; keep experiences contextualized.
- Environment—Unlike desktop experiences, AR happens anywhere. So, aim primarily for users’ contexts regarding whether they’re outdoors/indoors and moving/static. Whatever their setting, users expect pleasurable, user-friendly experiences. AR UX’s Rob Manson stipulates user scenarios:
- Public—interacting with software, using the entire body
- Personal—using smartphones in public spaces
- Intimate—sitting, using a desktop
- Private—using a wearable
- Comfort—Make comfortable designs to prevent physical strains and reduce cognitive load.
- Security—AR data is rich; so, design to ensure users’ data is secure.
To get started with AR design, you should:
- Familiarize yourself with AR terminology and a new form of information architecture.
- Constantly ask “Where are users?” and how they’ll apply and adopt your design.
- Remember physical limitations—users hold devices longer while seated, etc.
- Make interfaces automatic, so users needn’t prompt with commands. Consider voice controls.
- Use AR-software-creating resources optimally (e.g., Apple’s ARKit).
- Offer easy onboarding.
- Provide clues and maximum predictability.
- Prioritize screen real estate.
- Design for accessibility.
- Design animations where you consider how frame rates and processing power impact on device compatibility.
- Ensure your design interprets and responds to users’ head movements and body gestures dynamically, so users can act intuitively and freely without giving commands.
Ultimately, understand what users—in various contexts—expect before you try to meet the experience demands. Do user testing that covers all feasible conditions (lighting, weather, etc.).

Take a deep dive into Augmented Reality with our course How to Design for Augmented and Virtual Reality .
Augmented reality (AR) and virtual reality (VR) are quickly becoming huge areas of technology, with giants like Apple, Microsoft and Google competing to provide the next big AR or VR experience. Statista predicts that the worldwide user base for AR and VR will reach 443 million by 2025, meaning that it is becoming increasingly important for UX designers to know how to create amazing VR and AR experiences. Designing for 3D experiences will require completely new ways of thinking about UX design—and the question is, are you well equipped to tackle this new field of design?
The good news is that while AR and VR hardware and software is changing dramatically, UX principles and techniques for 3D interaction design will remain consistent. It’s just that new opportunities and sensitivities will present themselves to designers and developers. This course will give you the 3D UX skills to remain relevant in the next decade and beyond. You’ll be able to create immersive experiences that tap into the novel opportunities that AR and VR generate. For example, you will need to bring together key UX concepts such as emotional design, social UX, and gamification in order to create an immersive AR or VR creation.
AR and VR need to be easy to use in order to provide users with experiences that wow. Avoiding common usability mistakes and applying the principles of storytelling will help you carefully craft 3D experiences that delight, intrigue, amuse, and most of all evoke the response you intended. You’ll need to engage users in first-person narratives by making use of spatially dynamic UI’s, including gaze, gesture, movement, speech, and sound—often used in combination.
During the course, you will come across many examples and case studies from spatial and holographic interface designers. You will master how to create immersive 3D content for AR and VR that provides rich user experiences. The course offers exercises and challenges throughout, all aimed at helping you and/or your team practice your emerging or existing AR/VR skills. You will be taught by Frank Spillers, who is a distinguished speaker, author, and internationally respected senior usability practitioner with over 15 years of experience in the field.
