The impact of Extended Reality (XR) on the audiovisual industry has been nothing short of revolutionary. From the early experiments in virtual reality (VR) in the 1960s to the widespread use of augmented reality (AR) and mixed reality (MR) today, the history of XR and how it intersects with the AV industry is a fascinating journey that has shaped the way we perceive and experience our reality. 

In this tech brief, we will explore the origins of XR, the advancements in XR technology, its impact on various industries, and the potential for its future use in AV. 

What is Extended Reality (XR)? 

Extended reality (XR) is an umbrella term encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR), technologies that blend virtual and physical environments. XR creates immersive, interactive experiences by merging digital content with the real world or fully immersing users in virtual environments. 

XR has completely reshaped the way stories are told, content is created, and how audiences engage with audiovisual content.

The Origins of Extended Reality (XR)

The origins of Extended Reality date back to the 1800s, when stereoscopes, binocular-like devices that used two lenses to trick the brain into perceiving 3D images, became popular among middle—and upper-class families. 

According to futurist Bernard Marr, Extended Reality concepts remained primarily science fiction until the mid-20th century. What we recognize today as VR and AR technology emerged in the 1950s, 1960s, and 1970s. 

Timeline of XR Development:

• 1800s: Stereoscopes popularize 3D viewing.
• 1935: Stanley Weinbaum publishes Pygmalion's Spectacles, predicting modern VR goggles. The main character, Dan Burke, explores a sensory-rich fictional world using goggles.
• 1956: Morton Heilig invents the first VR machine, combining 3D video, sound, smells, and tactile feedback.
• 1960: Heilig patents the first head-mounted display with stereo sound and stereoscopic visuals.
• 1968: Ivan Sutherland creates "The Sword of Damocles," the first AR headset displaying computer-generated graphics.
• 1985: VPL Research Inc. begins selling VR goggles and gloves.
• 1987: Jaron Lanier coined the term "virtual reality."
• 1990s: VR arcade games popularize XR technologies, introducing immersive experiences to the masses.
• 1990s: AR technology advances, and the concept of merging VR and AR into Extended Reality (XR) emerges.

These early developments in XR set the stage for the evolution of immersive technologies that we see today in the mainstream world. 

What is Virtual Reality?

In virtual reality (VR), users immerse themselves in interactive, computer-generated environments that replace their perception of the real world, creating a convincing 3D sensory experience. 

Virtual reality environments are created using VR software and presented to the user so that they supersede the real world, creating suspension of disbelief and helping the user experience and interact with the 3D world.

How Virtual Reality Works

Virtual reality works through a headset that displays a stereoscopic 3D scene, tracking your head movements via built-in sensors such as gyroscopes and accelerometers. Combined with controllers, trackers, and specialized software, VR creates realistic visuals, immersive audio, and lifelike environments that enhance the feeling of being in another world.

Types of Virtual Reality

Virtual reality (VR) technologies offer varying levels of immersion, from simple on-screen experiences to fully immersive virtual worlds. Related technologies like augmented reality (AR) and mixed reality (MR) blend virtual elements seamlessly with our physical surroundings.

Here are the main types of virtual reality technologies:

• Non-immersive VR: Users view a 3D environment displayed on a conventional 2D screen, such as computer monitors or TVs. Interaction is limited, offering minimal immersion (e.g., traditional video games).
• Semi-immersive VR: A projection-based system creates a partial virtual environment, often used in simulations or training. It typically involves larger screens or projectors for greater engagement, though users remain aware of the real-world environment.
• Fully immersive VR: Users wear headsets that completely immerse them in a virtual environment. Sensors track head movements, and realistic visuals and sound enhance the immersive experience.
• Augmented Reality (AR): Digital elements are overlaid onto the real world, typically viewed through smartphone cameras or AR glasses, enriching real-world environments with virtual details.
• Mixed Reality (MR): Combines VR and AR by integrating virtual objects into the physical world in an interactive way, allowing users to manipulate virtual elements within real-world settings.

Benefits of Virtual Reality

VR creates realistic, hands-on training scenarios, enhancing skill development and improving knowledge retention in fields such as aviation, medical procedures, and education.

In healthcare, VR can provide effective pain management, accelerate rehabilitation, and reduce anxiety through immersive therapeutic experiences. Because of its engaging nature, VR boosts user participation, making experiences more enjoyable—even when the primary goal is education or therapy.

Additionally, VR saves time and money. Virtual prototypes and simulations in design and engineering streamline product testing and evaluation, cutting development costs and timelines. Similarly, therapeutic scenarios and training sessions can be conducted virtually, eliminating the need for travel. Ultimately, VR broadens access to valuable new experiences across travel, education, and professional training.

Challenges and Limitations of Virtual Reality

Despite its potential, virtual reality also faces challenges and limitations. Motion sickness and discomfort are common issues associated with VR, as the disconnect between what the eyes see and what the body feels can lead to nausea and disorientation. 

The cost of VR equipment, such as headsets and PCs with high-end graphics, can be a barrier to adoption for many consumers. Technical limitations, including latency and resolution, affect the overall immersive experience and realism of VR. The use of personal data and biometric information in VR environments raises ethical concerns related to privacy and surveillance. 

Lastly, the lack of content and slow adoption of VR technology in mainstream markets pose challenges for the industry.

Future of Virtual Reality

As technology continues to evolve, VR headsets and graphics are expected to improve, providing a more realistic and immersive experience for users. Additionally, the integration of artificial intelligence in virtual environments will enhance interactivity and personalization, making VR more engaging and adaptive. 

Virtual reality is also expected to expand into new industries, such as retail, marketing, and social networking, offering unique and interactive experiences for consumers. The cultural and societal impact of VR will continue to shape how we communicate, learn, work, and interact with the world around us, presenting both challenges and opportunities for the future.

What is Augmented Reality?

Augmented Reality, or AR, overlays digital information like images, videos, or 3D models onto the real world. Its roots date back to the 1960s but have gained significant attention over the last decade due to technological advancements. 

AR differs from Virtual Reality (VR) in that it doesn't create an entirely artificial environment but rather enhances the existing environment. This is achieved through the use of cameras, sensors, and displays to merge the virtual and real world seamlessly. The applications of AR are vast, ranging from healthcare, education, and retail to gaming and entertainment. 

The Technology Behind Augmented Reality

At the core of Augmented Reality are hardware, software, sensors, display technologies, and user interfaces. Hardware such as smartphones, tablets, and AR glasses are commonly used to experience AR.
