Introduction to Artificial Reality
Artificial reality refers collectively to augmented reality (AR), virtual reality (VR), and mixed reality (MR) technologies that blend digital content with the real world to create immersive synthetic environments and enhance our perceptions of reality. These technologies are empowering radical new applications for entertainment, training, simulation, healthcare, engineering, and more.
Technologies Enabling Artificial Reality
There are three core categories of artificial reality technologies:
Augmented Reality (AR)
AR overlays digital information and virtual objects onto our views of the real world through devices like smartphones and AR glasses or contacts. AR does not replace reality but enhances it with supplementary contextual data.
Virtual Reality (VR)
Mixed Reality (MR)
As an in-between technology blending both physical and digital realities, MR integrates virtual and augmented realities to allow synthetic content to interact with the environments around users. This integration enables a world where real and virtual dynamically communicate and influence each other.
Key Components of Artificial Reality Systems
To create the illusions of alternative or enhanced realities, artificial reality systems are composed of three core components working in conjunction:
Visual Components
The visual aspects are what users predominantly perceive as AR, VR, or MR environments. Key visual technologies include head-mounted displays, 360-degree cameras, and graphical interfaces and rendering tools to develop environments and assets.
Audio Components
Spatial audio technologies that simulate surround sound and acoustic environments are equally vital in providing sensory depth and cues that reinforce immersion within artificial realities. Binaural audio and auralization techniques enable this by processing sound waves to mimic auditory experiences.
Haptic Components
Emerging haptic technologies, particularly gloves and suits with tactile feedback actuators, better simulate sensations of touch and interaction within AR/VR and link the experiences more intimately to our senses of the real, physical world for heightened realism.
Use Cases and Applications
Artificial reality empowers innovative applications across many sectors:
Entertainment
From immersive theater performances and concerts to interactive theme park rides, artificial reality delivers next-generation entertainment built around digital fantasy worlds we can inhabit within mediums like VR narrative games and multimedia experiences.
Education and Training
VR corporate training and even full digital university campuses provide adaptable environments where students can deeply engage educational content through roleplaying occupational scenarios, manipulating objects difficult to access physically, visualizing processes at micro and macro levels simultaneously with AR, and more.
Healthcare
Doctors can leverage AR during complex surgery by overlaying vital anatomical data onto patients in real time. VR therapy can also help patients overcome anxieties, PTSD triggers, and chronic conditions through customized and controlled exposure treatment programs.
Engineering and Design
AR allows engineers and architects to rapidly iterate 3D models, test prototypes, and inspect construction plans in context onsite using only mobile devices. This yields more practical feedback to perfect and troubleshoot designs.
Military
The military utilizes VR combat simulations replicating scenarios that are too dangerous, expensive, or impractical to create physically to rigorously and realistically train personnel for high-risk missions and emergency response.
Marketing and Advertising
AR enables creative brand activations and ad campaigns with digital content about products and services embedded in the world around consumers – effectively bridging the gap between the virtual and material by merging them using location-based triggers.
Benefits and Advantages of Artificial Reality
Artificial reality delivers transformational impacts across many facets of society and human life by:
Immersive Experiences
Unlike any previous mediums, these technologies enable forming visceral connections to digital environments by completely encompassing our sight, hearing, touch, and movement to foster an innate sense of existing inside an alternate reality – leading to unparalleled engagement.
Increased Accessibility
AR and VR allow experiencing simulations of scenarios that may be impossible, far too risky, or resource-intensive to access physically, democratizing availability. Traveling to Mars or performing open heart surgery becomes available to anyone.
Enhanced Visualization
Abstract data, processes, and ideas unreadable to humans can be brought to life in intuitive ways leveraging AR/VR’s powers of dimensional representation and simplification. This amplified clarity yields insights impossible with text or 2D images alone.
Improved Learning and Skills Development
The combination of immersion, increased accessibility, and enhanced visualization catalyzes efficient and sticking learning opportunities as users directly practice hands-on activities transferable to real occupations through realistic VR training.
Challenges and Limitations
While promising, artificial reality still faces adoption hurdles around:
Motion Sickness
Visually-induced motion sickness remains problematic for some within certain VR environments if too many inaccurate visual motion cues are triggered. However, developers are finding better ways to optimize experiences around this biological limitation.
Lack of Content
A vast amount of purpose-built digital assets, environments, and tools will be required for artificial reality to be practical at scale. Currently much of this framework needs to be created mostly from scratch involving high development costs.
Cost Barriers
Premium VR headsets, haptic gloves/suits, and underlying computing hardware remains prohibitively expensive making purchase and trial still difficult for average consumers and smaller organizations on tighter budgets even as costs gradually decrease.
The Future of Artificial Reality
Even as an emerging technology category, artificial reality innovation continues accelerating ahead through:
5G Connectivity
Latency reductions allowing intricate and social AR/VR experiences requiring substantial data transfer will grow practical thanks to expanding 5G infrastructure delivering necessary wireless bandwidth.
More Realistic Environments
With artificial intelligence (AI), enough data from physical spaces, and improved photogrammetry techniques for capturing detailed models, AR/VR worlds will shift closer to reality across visual, audio, and tactile elements.
Ubiquitous AR Experiences
Enabled by ubiquitous mobile devices with ever more advanced cameras and sensors, passive and interactive AR augmentations overlaying helpful cues upon daily moments and tasks for users will dominate as a mainstream interface paradigm.
Conclusion
From radical new entertainment mediums to serious professional training tools, artificial reality innovation continues marching ahead driven by an ambitious collective vision for enhanced human experiences powered by immersive digital simulation. Despite current growing pains as an early-stage technology cluster, the foundations now laid through recent advancements foreshadow artificial reality’s coming impact permeating throughout people’s lives in the imminent future.
