Approximately every decade since the 1970s, there seems to have been a major transformation in the technology industry. Each transformation is typically illustrated by a leap forward in how we interact with and apply technology and data in our daily lives. The 1970s saw the initial transition from large mainframes in clean rooms to desktop personal computers, where interaction was facilitated through the keyboard and keystrokes. In the 1980s, the introduction of the graphical user interface (GUI) allowed interaction with data through the mouse and the pointer. The 1990s saw the commercial adoption of the Internet, allowing the sharing of data globally. In the following decade, the explosive success of the smartphone led to touch—and later, voice—becoming our primary interface. In this decade, we are moving into the next transformation—digital realityTM, where our means of interface is expected to be the gesture, our emotions, and our gaze.1
In this technical primer, we refer to the gamut of augmented reality (AR), virtual reality (VR), mixed reality (MR), 360° video, and immersive experience capabilities as digital reality, except when alluding to the individual technology in its specific sense.2 In later sections, we define these technologies and describe their drivers, possible challenges in implementation, market potential, and some industrial applications.
Defining digital reality
Digital reality is generally defined as the wide spectrum of technologies and capabilities that inhere in AR, VR, MR, 360° video, and the immersive experience, enabling simulation of reality in various ways (see figure 1).3
To comprehend digital reality, we need to understand the concepts that it encompasses. While VR enables users to immerse themselves in artificial surroundings that portray actual places or imaginary worlds, AR overlays contextual information on the actual physical environments users see, thus combining digital components and experiences with real life.4 MR characterizes the controlled impact of the AR/VR and the Internet of Things (IoT) trends. MR brings together the virtual and real worlds to generate new environments in which both digital and physical objects—and their data—can coexist and interact with one another.5 360° video provides a new perspective that allows users to look in every direction. This is achieved by shooting with an omnidirectional camera or a collection of cameras. Immersive experience creates a multisensory digital experience that can be delivered using VR, AR, MR, and 360° video, among other technologies.6
Building blocks of digital reality
Digital reality enables the seamless use of digital information to make choices in real time as we accomplish tasks.
The three key foundational elements that reinforce digital reality (figure 2) are as follows:
- Source of data: The process begins at the point where information is created, taking us outside the territory of pure digital reality and into another connected technology, the IoT. Users of digital reality need to access digital information about the world in real time from various sources via sensors, and communicate that information so that it can be collected, evaluated, and acted upon, which is what the IoT is all about.7 Enterprise data—customer relationship management (CRM), enterprise resource planning (ERP), computer aided design (CAD)—can present the user with content and help him/her identify the next action. Analytics, platform computing, and network can also be important components of an overall solution.
- Method of presentation: An information overload can overwhelm users, which could in turn lead to poor performance. The data provided should be sufficient but not excessive, depending on the complexity of the application. Much of the current research into digital reality focuses on how to present relevant digital information in increasingly natural, easy-to-comprehend, contextual ways, so that users can absorb it effortlessly.8
- Interaction with and use of data to drive action: Even the right data presented in the right way would be of no use if it doesn’t create value. Digital reality not only enables the display of digital information, but also the control of it in increasingly natural ways. Digital reality takes the comparison of human and machine one step further by enabling us to ponder the question: “What happens if humans and the machines collaborate?” It is fundamentally about making the human-machine team work as naturally as possible.9

While we have discussed some of the key factors influencing the growth of the digital reality market, we should also be aware of hurdles to the adoption of digital reality applications and evaluate potential solutions.
Applying digital reality to industries
An increasing number of industries outside gaming and entertainment have started testing and adopting digital reality technologies for various applications. Some of the current and potential digital reality-related applications are described below:
- AR devices such as smart glasses allow engineers to provide guidance on complex tasks to maintenance workers in remote locations and at the same time view a real-time and interactive demonstration of the repair job.38
- VR can help address the shortage of skilled engineers for maintenance, repair, and overall operations (MRO) by augmenting local engineering skills with the expertise of more qualified technicians from any location at any time, potentially reducing training time, improving maintenance efficiency, and enabling huge cost savings.39
- Aircraft component manufacturing companies are developing MR applications, with which the position of engineers installing equipment inside aircraft fuselages can be mapped to a full-scale 3D digital model of the aircraft they are working on. This enables engineers to instantly bring up an image of an aircraft component installation and can help them ensure that they have fixed it correctly.40
- AR is being extensively used by the military for more effective training of soldiers.41
- Smart helmets allow commanders to send maps and other information directly to the soldiers’ field of vison, enabling them to perform their missions with enhanced safety, speed, and coordination.42
- MR applications in the future may involve drones small enough to fit into the palm of a soldier’s hand. The drones can then track and analyze a soldier’s movements under a training simulation and real-world combat situations.43
- AR often plays a crucial role in vehicle design. Manufacturers can use the technology to compare virtual data with the actual vehicle design, perform analysis, and, on that basis, potentially alter parts during the initial stages of design planning. In this way, the technology can provide manufacturers with an exact picture of a car’s future performance, possibly reducing time and cost of launch.44
- Potential applications of AR, such as projecting navigation routes and distance between the car and road obstacles or pedestrians, may be displayed on car windshields instead of traditional dashboard screens, allowing the driver’s vision to stay on the road.45
- Carmakers are also experimenting with MR technology that enables them to combine and visualize physical vehicles and computer imaging to improve design and speed up development.46
- VR can potentially enable surgical specialists to treat patients remotely using a remote-controlled robot. Using an HMD and haptic gloves, a surgeon could virtually perform a surgery thousands of miles away.47
- MR is being used for the preoperative preparatory phase of surgical procedures, where surgeons can plan the entire operation using 3D holograms, decide on where to make incisions, and also see the consequences of their moves.48
Consumer products and services
- AR allows online shoppers to view products such as clothes, furniture, and other items in 3D in a real-life environment, in real time through their tablets or smartphones before purchasing.49
- Travelers can explore scenic places, cities, or hotels in a travel destination through a VR headset.50
Key considerations for organizations
As companies extract value from information gathered during the execution of daily tasks, sifting through voluminous amounts of data for a complex operation may soon surpass the competency of most people.51 Digital reality would thus become increasingly essential for processing this data as well as dealing with the variability of the task (when each iteration of a task is different). Digital reality technologies offer various prospects for enterprises to transform areas such as internal workforce communication and collaboration, workforce training and simulation, and customer service.52 The combined effect of factors, including declining hardware and software costs, increased smartphone usage, and creation of app ecosystems, have led to the proliferation of digital reality applications in both consumer and enterprise segments as discussed earlier.53
With the advent of digital reality solutions, enterprises may need to upgrade their infrastructure by installing sensors and beacons, among other systems, to facilitate augmented setups. They may also need to improve connectivity—in the form of wired, wireless, and cellular—to cater to digital reality requirements in remote locations. Companies should consider investing in new tools and services such as high-definition 3D image capture, mapping equipment, and high-end gaming engines, to recreate simulations and virtual environments for digital reality interaction.54
Additionally, change management can be essential for organizations to train their workforces and make them technology-ready. The use and adoption of such digital reality tools as smart glasses and HMDs could position organizations to take advantage of digital reality applications to increase the effectiveness of training and enable production efficiencies.55
Simply put, organizations can use digital reality capabilities to their full potential to streamline their workflow, drive collaboration and productivity, and enhance the customer experience—and, in the process, perhaps build brand value.
The application of digital reality today appears to go well beyond the consumer segment, with a reach that extends across the enterprise world. Accordingly, businesses should consider investing in infrastructure and developing new operating models to improve connectivity and fast track the adoption of digital reality technologies. Indeed, digital reality is swiftly progressing from hype to reality, as is evident from the market growth realized over the years, offering a plethora of benefits to organizations. The time seems apt for the full array of business professionals—from product planners to strategists to marketing and beyond—to understand the disruptive potential of digital reality and put the technology to use.
