The Origins of VR Headsets
Virtual reality headsets have a fascinating history that dates back several decades. Let's dive into some key milestones and early developments.
- 01The first VR headset was patented in 1960 by Morton Heilig. It was called the "Telesphere Mask" and provided stereoscopic 3D images with wide vision and stereo sound.
- 02Morton Heilig also created the Sensorama, a large booth that could fit up to four people at a time. It combined multiple technologies to stimulate all the senses: full-color 3D video, audio, vibrations, smell, and atmospheric effects like wind.
- 03The term "Virtual Reality" was coined in the late 1980s by Jaron Lanier, the founder of the Visual Programming Lab (VPL).
- 04Queen Elizabeth II was one of the first users of virtual tours. In 1994, she opened a historic museum visitor interpretive tour viewing of Dudley Castle in England as it was in 1550 through 3D reconstruction using a computer-controlled laserdisc-based system.
Evolution and Market Growth
From simple beginnings, VR headsets have evolved into sophisticated devices. The market has seen significant growth and technological advancements.
- 05Google Cardboard was initially a passion project under the "20% Project" or "Innovation Time Off" policy. It allowed users to experience virtual reality in a simple, fun, and affordable way using cardboard as its main component.
- 06Virtual reality in healthcare has proven revolutionary. 3D software, diagnostic images from scans and ultrasounds are used to create 3D virtual models that can be useful in diagnostics, treatment, and practicing surgical procedures. It also shows improvement among patients with PTSD, anxiety, and depression.
- 07Varjo is a company pushing virtual and augmented reality to the next level. Their products feature human-eye resolution, integrated eye tracking, and broad software compatibility. Their mission is to view the world using VR like how the human eye does.
- 08The global VR market size is projected to increase from less than $12 billion in 2022 to more than $22 billion by 2025.
- 09Notable VR headset suppliers include Pico, Sony, and Meta. In June 2023, Mark Zuckerberg announced the company’s next-generation VR and mixed-reality headset in the form of Meta Quest 3.
- 10Apple announced its entry into the VR market with the Apple Vision Pro, an upcoming mixed-reality headset announced on June 5, 2023, at its 2023 Worldwide Developers Conference (WWDC). The headset will sell for $3,499.
Technological Advancements
Advancements in VR technology have made headsets more immersive and user-friendly. Here are some key technological developments.
- 11Meta announced the Meta Quest 3 on June 1, 2023, and it was launched on October 10. The Meta Quest 3 is a mixed-reality headset featuring significant advancements in display quality, processing power, and tracking capabilities. It boasts a resolution of 2160 x 2160 per eye and inside-out tracking with improved accuracy and field of view.
- 12HTC released its HTC VIVE SteamVR headset in 2016, which was the first commercial release of a headset with sensor-based tracking allowing users to move freely in a space.
- 13Haptic interfaces are systems that allow humans to interact with a computer using their touch and movements. By 2016, most headsets had dynamic binaural audio, but haptic interfaces were still underdeveloped.
- 14The PlayStation VR headset developed by Sony engineers came about from an open-ended tinkering session without any executive direction. This approach led to innovative design and functionality.
- 15Virtual reality travel is a growing field. In 2015, Marriott boasted about its ability to transport clients from London to Maui in 90 seconds using Oculus technology.
- 16No single person invented virtual reality. Instead, many people have contributed to its growth, including Morton Heilig, Jaron Lanier, Douglas Engelbert, Ivan Sutherland, and Myron Kreuger. Collaboration, prototyping, and iteration have been fundamental to the development of this versatile technology.
Key Features and Components
Understanding the key features and components of VR headsets helps appreciate their complexity and functionality.
- 17VR headsets typically use at least one MEMS IMU for three degrees of freedom (3DOF) motion tracking. Optionally, more tracking technology can be used for six degrees of freedom (6DOF) motion tracking. Sensor fusion algorithms, often variants of a Kalman filter, are used to merge data from the IMU and other tracking sources.
- 18The image clarity in VR headsets depends on the display resolution, optic quality, refresh rate, and field of view. Because VR headsets stretch a single display across a wide field of view, flaws in display technology become more apparent, such as the screen-door effect.
- 19The lenses of the headset are responsible for mapping the up-close display to a wide field of view while providing a more comfortable distant point of focus. Fresnel lenses are commonly used due to their compactness and lightweight structure. However, they introduce distortion and chromatic aberration, which are typically corrected in software.
- 20The lenses can be adjusted dynamically to account for a user’s eyeglass prescription, allowing the user to use the headset without corrective eyeglasses.
- 21Virtual reality headsets have significantly higher requirements for latency than ordinary video games. The ideal latency is 7-15 milliseconds. If the system is too sluggish to react to head movement, it can cause the user to experience virtual reality sickness, a kind of motion sickness.
- 22The graphics processing unit (GPU) needs to be powerful enough to render the required amount of frames. Oculus cited the limited processing power of Xbox One and PlayStation 4 as the reason why they targeted the PC gaming market with their first devices.
- 23Foveated rendering is a new technique to reduce the rendering workload. It uses eye tracking hardware to determine at what point the user is looking and reduces rendering resolution farther from the user’s gaze. This can be unnoticeable to the user because human peripheral vision is far less sensitive than the fovea.
- 24VR headsets can support motion controllers, which combine inputs from accelerometers and gyroscopes with the headset’s motion tracking system. This enhances the immersive experience by allowing users to interact with virtual objects more naturally.
- 25AR headsets are similar to VR headsets but enable the user to see and interact with the outside world. Examples include the Apple Vision Pro and Meta Quest 3.
Applications of VR Technology
VR technology is not just for gaming. It has a wide range of applications across various industries.
- 26Virtual reality is used in education to create immersive learning experiences. It can help students visualize complex concepts and historical events in a more engaging way.
- 27Virtual reality is used in therapy to treat psychological disorders such as PTSD, anxiety, and depression. It provides a safe and controlled environment for patients to confront their fears and anxieties.
- 28Virtual reality is used in training and simulation to provide realistic and immersive training experiences. It is commonly used in industries such as aviation, military, and healthcare.
- 29Virtual reality is used in design and engineering to create 3D models and visualize designs before they are built. It helps designers and engineers identify potential issues early on and make necessary adjustments.
- 30Virtual reality is used in medical research to create 3D models of the human body and simulate surgical procedures. It helps researchers understand complex medical conditions and develop new treatments.
