What is Virtual Reality?

Virtual reality (VR) is the experience where users feel immersed in a simulated world, via hardware—e.g., headsets—and software. Designers create VR experiences—e.g., virtual museums—transporting users to 3D environments where they freely move and interact to perform predetermined tasks and attain goals—e.g., learning.

To create great VR experiences, its vital to design with a first-person perspective in mind.

VR—Entering New Worlds Through Equipment

In VR design, your goal is for users to experience an alternative existence through whichever senses your design can access. The more your design reaches your users through—particularly—sight, hearing and touch, the more immersed they will be in virtual reality. You therefore want to isolate users as far as possible from the real world.

VR’s history began with the View-Master (a stereoscopic visual simulator) in 1939 and Morton Heilig’s 1950s’ Sensorama multi-experience theatre. The development of the first head-mounted display (HMD) followed in 1968. Then, designers focused on professionally geared applications in the 1970s and 1980s. With more sophisticated technology, they could tailor computerized VR experiences to the fields of military training, medicine and flight simulation. After 1990, just after “Virtual Reality” became popularly known, VR entered the wider consumer world through video-games. VR has since become progressively more affordable and sophisticated.

Virtual Reality vs Augmented Reality vs Mixed Reality

In virtual reality, you isolate the user from the real world and create presence in a virtual environment.

VR differs from augmented reality, where users remain anchored in the real world but experience computerized overlays. AR and VR—along with mixed reality (MR), where users interact with digital elements which are anchored to the real world—come under the umbrella term extended reality (XR). In AR, users employ devices (e.g., smartphones) to find parts of the real world (e.g., a room) overlaid with computer-generated input. Designers insert a range of digital elements such as graphics and GPS overlays which adjust to changes in the user’s environment (e.g., movement) in real time. In MR, users have a more sophisticated experience where digital interplays with real-world content—e.g., surgeons operating on patients via projected ultrasound images. In VR, users’ real-world movements translate fully to preprogrammed environments, letting them play along with convincing VR illusions. So, in VR design you offer users near-total escapism.

“Virtual Reality is really a new communication platform. By feeling truly present, you can share unbounded spaces and experiences with the people in your life. Imagine sharing not just moments with your friends online, but entire experiences and adventures.”

— Mark Zuckerberg, Facebook’s CEO

VR—Designing to Dupe the Senses

In VR, you have three “genres” to reach users:

  1. Hyper-immersive or emotion-based designs (which can involve scents).
  2. Live-action-style POV (first-person point-of-view) documentaries (e.g., exploring virtual rainforests).
  3. Games and gamified experiences.

To design VR experiences, you must understand human physiology and psychology—users’ needs, limitations, etc.—and what makes VR experiences enjoyable versus unpleasant.

You should focus on:

  1. Believability—Incorporate features (principally images and sound) to envelop users entirely in 3D environments.
  2. Interactivity—Make designs intuitive; remove outside-world interference. While you’re presenting brand-new environments, how users interact with these must match what they’re used to doing in the real world (e.g., punches are still punches).
  3. Explorability—Ensure users can freely move about and discover the “reality” offered.
  4. Immersiveness—By combining the above factors, you achieve the goal: inserting users presences in your design.

Throughout the design process, you should consider:

  1. Safety and Comfort—Prevent virtual-reality sickness (like motion sickness, but stemming from sensory conflict/triggers from artificial environments). You want to immerse users in a—virtually—hermetically sealed environment. However, they can become disoriented. Users’ bodies are different. Where they experience VR can be just as varied. When they can move freely using your design, they can collide with/trip over things or fall. While some devices—e.g., the HTC Vive—warn users about objects, don’t overlook safety. Neck strains can arise from headset use. Additionally:
    1. Let users see and use controls/menus.
    2. Avoid changes in brightness and speed (don’t accelerate users; avoid flashing lights).
    3. Keep frame rates high.
    4. Keep peripheral motion minimal—users typically have 180-degree vision.
  1. Interaction and Reaction—Design ergonomically for users’ natural movement. Systems’ head-tracking, motion-tracking and (possibly) eye-tracking sensors and hand controllers must respond dynamically. That means they must offer instant control which reflects real-world behavior. Users’ arms have 50–70-cm reach; so, place key interactions in this zone.
  2. Image and Text Scale—Prevent eye strain and help user orientation with depth perception: your visuals keep changing, so make images more detailed as users approach them. Use eye-catching text. Comfortable focusing distances are typically 0.5–20 meters.
  3. Sound—Use sound for atmosphere, and to give users a sense of place in the environment and cues.

As VR keeps advancing into the mainstream, a demographic shift is inevitable as more users expect to be teleported into exciting new experiences.The less they sense your interface, the more immersed they become.

Take a deep dive into Virtual Reality with our course Design Thinking: The Beginner’s Guide .

Some of the world’s leading brands, such as Apple, Google, Samsung, and General Electric, have rapidly adopted the design thinking approach, and design thinking is being taught at leading universities around the world, including Stanford d.school, Harvard, and MIT. What is design thinking, and why is it so popular and effective?

The overall goal of this design thinking course is to help you design better products, services, processes, strategies, spaces, architecture, and experiences. Design thinking helps you and your team develop practical and innovative solutions for your problems. It is a human-focused, prototype-driven, innovative design process. Through this course, you will develop a solid understanding of the fundamental phases and methods in design thinking, and you will learn how to implement your newfound knowledge in your professional work life. We will give you lots of examples; we will go into case studies, videos, and other useful material, all of which will help you dive further into design thinking.

This course contains a series of practical exercises that build on one another to create a complete design thinking project. The exercises are optional, but you’ll get invaluable hands-on experience with the methods you encounter in this course if you complete them, because they will teach you to take your first steps as a design thinking practitioner. What’s equally important is you can use your work as a case study for your portfolio to showcase your abilities to future employers! A portfolio is essential if you want to step into or move ahead in a career in the world of human-centered design.

Design thinking methods and strategies belong at every level of the design process. However, design thinking is not an exclusive property of designers—all great innovators in literature, art, music, science, engineering, and business have practiced it. What’s special about design thinking is that designers and designers’ work processes can help us systematically extract, teach, learn, and apply these human-centered techniques in solving problems in a creative and innovative way—in our designs, in our businesses, in our countries, and in our lives.

That means that design thinking is not only for designers but also for creative employees, freelancers, and business leaders. It’s for anyone who seeks to infuse an approach to innovation that is powerful, effective and broadly accessible, one that can be integrated into every level of an organization, product, or service so as to drive new alternatives for businesses and society.
