Defining the Augmented & Virtual Environment Spectrum
Before analyzing the nitty-gritties differentiating augmented reality (AR) and virtual reality (VR), we should ground our exploration in concise working definitions of these emerging reality-augmenting platforms.
Augmented Reality refers to seamlessly overlaying and anchoring virtual digital information onto objects perceived in the real physical environment. AR supplements tangible real-world settings and scenarios with additional computer-generated sensory inputs – delivered in real-time through enabling technologies like handheld devices, head-worn displays, and spatial mapping infrastructure.
Examples: Consumer AR applications like interactive game-play, educational content layered over textbooks, restaurant reviews visually pinned to storefronts etc.
In comparison, Virtual Reality implies digitally simulating artificial 3D environments that perceptually displace real-world physical settings with enclosed, fictional spaces purpose-built for said simulation. Done right, these virtual playgrounds elicit cognitive presence – tricking the brain into feeling artificially generated environments as tangible places.
Examples: Highly immersive VR gaming titles, pilot training in simulated flight cockpits, walkthroughs of building architecture prior to construction etc.
Unlike AR which supplements reality, VR aims to replace it.
Tracing the History and Evolution
The origins of both augmented and virtual reality stretch back earlier than many imagine. Lightweight head-mounted displays prototyped in 1968 by Harvard researcher Ivan Sutherland outlined foundational concepts like stereo 3D camera linkage that would shape some of today‘s VR approaches.
Meanwhile Myron Krueger‘s artificial reality labs in the 1970s coined the term "augmented reality" describing responsive camera-projector systems that would influence current mobile AR applications.
Through the 1980s and 90s, pioneers like VPL Research founder Jaron Lanier pushed virtual environment simulations combining goggles, gloves and bodysuits – forging a path for current consumer VR products from Oculus and HTC.
Researchers uniformly aimed to enhance how humans perceive and interact with the world – by either augmenting or replacing it through emerging digital means.
Significant leaps have occurred since in the core enabling hardware, software, algorithms and infrastructure elements underpinning both categories of technology.
Peering Behind the Curtain
Comprehending exactly how AR overlays enhance reality while VR replaces it outright entails peering behind the curtain to inspect some of the technological building blocks powering both.
Enabling Augmented Reality
Rendering digital assets anchored to real-world objects in physical space involves capturing environmental data through cameras and sensors, generating context maps through real-time computer vision, rendering overlays adjusted to perceived surfaces and lighting conditions – all with minimal lag between input and output.
Key aspects include:
- Color cameras form core visual inputs, supplemented by depth, infrared and other sensor data
- Simultaneous Localization and Mapping (SLAM) algorithms construct spatial maps using visual feature tracking
- Anchoring overlays to detected surfaces after accounting for visibility, reflections etc.
- Leveraging hardware acceleration in mobile chipsets to deliver low-latency experiences
Solving this multifaceted challenge allows augmenting reality through visuals registered and rendered contextually in real-time. When done right, the real and the virtual merge seamlessly.
Manufacturing Virtual Reality
Unlike AR which enhances existing environments, VR necessitates modeling full 3D worlds from scratch while completely controlling how users perceive and interact within simulated spaces. This poses its own complex challenges around:
- Stereoscopic rendering coordinating distinct images for each eye
- Tracking head motions and controller inputs to enable intuitive control
- Updating renders dynamically when users move to showcase motion parallax
- Minimizing lags between input and refreshed frames to avoid discomfort
- Modeling life-like physics, lighting, acoustics and haptic effects
Smoothly blending solutions across these areas transports users into the realm of modern virtual reality – seemingly detached from the constraints of physical reality.
Both AR and VR leverage interdisciplinary physics and computing research to push the boundaries of what emerging spatially-aware technologies can achieve. But significant open challenges continue confronting researchers before augmented and virtual realities reach their full disruptive potential.
Peering Over the Horizon
Recent attention may position AR and VR as relatively new phenomena – but steady research advances tackle both long and short-term capability challenges facing each platform.
Paving the Road Ahead for AR
Ever more performant smartphone chipsets and computer vision tune the accuracy and realism of augmented overlays – but fundamental limitations remain around dynamically modeling real-world lighting, physics and occlusions in complex scenes.
Key open research problems include:
- Expanding reflectivity and ambient occlusion models for AR assets
- Leveraging machine learning to extrapolate reasonable hidden geometry
- Reducing computational complexity to enable persistent tracking across conditions
- Generalizing AR capabilities across devices with varying capabilities
As solutions take shape in labs – we inch towards augmented reality blending more seamlessly into the real world.
Plotting the VR Roadmap
Unlike AR which enhances existing visible environments, VR necessitates modeling immersive environments from the ground up. Doing so poses intertwined hardware and software problems like:
- Upgrading field of view without disproportionately increasing cost and form-factors
- Standardizing smooth, high-resolution varifocal displays decoding focus depth
- Integrating realistic ambient occlusion, soundscapes and physics
- Developing efficient accommodation mechanisms between virtual motion and vestibular mismatch
- Coordinating shared multiplayer VR spaces across geographic distances
As milestones emerge addressing these roadmap items – virtual worlds come another step closer toward replicating tangibility – liberated from physical restrictions.
Of course, applications currently on the market press today‘s technological envelope delivering engrossing value without solving open research dilemmas. But pushing theoretical limits unlocks the true disruptive potential of simulated environments generated computationally rather than constructed physically.
