Virtual and Mixed Reality

Virtual reality (VR) and mixed reality (MR) encompass technologies that immerse users in computer-generated or hybrid environments, blending digital content with the physical world. In VR, head-mounted displays present fully synthetic three-dimensional scenes that respond to head and hand movements, fostering the impression of “being there.” Mixed reality extends this by anchoring virtual objects to real-world coordinates, enabling seamless interaction between real and digital elements. Core components include high-resolution stereoscopic displays, accurate six-degrees-of-freedom tracking, spatial audio and increasingly sophisticated haptic and olfactory feedback. Applications span education and training (flight, medical and industrial simulators), collaborative design and prototyping, remote maintenance and therapeutic interventions for phobias or rehabilitation. The global market growth is driven by advances in mobile AR platforms, untethered VR headsets and enterprise adoption for immersive analytics. As visual-computing engines, artificial intelligence and low-latency networking converge, VR and MR are catalysing novel workflows in manufacturing, healthcare, entertainment and social collaboration, promising more natural, context-aware and accessible experiences across industries.

Research from Nature Portfolio

Recent studies have demonstrated the integration of olfactory feedback modules with head-worn AR displays to heighten immersion and emotional engagement, revealing measurable improvements in user attention and recall within mixed-reality design prototypes. In a parallel advance, theoretical and policy analyses have proposed governance frameworks for the metaverse based on technical standards, identifying key phases of standards formulation and compatibility measures needed to ensure security and interoperability across emerging virtual, augmented and mixed-reality environments.

Research from all publishers

Recent taxonomic surveys have characterised the metaverse architecture, delineating core hardware, software and content components alongside user-interaction, system implementation and application domain perspectives, and mapping open challenges in scalability, standardisation and social impact. Complementary reviews of artificial intelligence within virtual and mixed-reality settings have shown how machine learning and natural language processing can personalise immersive content delivery, automate routine tasks and enhance sensor fusion, while calling attention to privacy and bias risks. Studies of blockchain integration in the metaverse have examined its role in securing digital assets, ensuring data integrity and enabling cross-platform interoperability, proposing solutions for data acquisition, storage, sharing and privacy preservation that underpin decentralised mixed-reality ecosystems.

Virtual and Mixed Reality publication trend

The graph below shows the total number of articles in virtual and mixed reality across all publications each year (not limited to Nature Index journals).

Technical terms

Virtual reality (VR): A fully computer-generated environment delivered via head-mounted displays and tracking systems that immerses the user in synthetic three-dimensional worlds.

Mixed reality (MR): A hybrid technology that anchors virtual objects to real-world spaces, allowing interactive digital content to coexist with the physical environment.

Immersion: The degree to which a system engages user senses (visual, auditory, haptic, olfactory) to create a compelling sensation of presence within a virtual or hybrid space.

Presence: The subjective experience of “being there” inside a virtual or mixed-reality environment, driven by sensory fidelity and responsiveness.

Six degrees of freedom (6DoF): The set of motion capabilities—three translational (forward/backward, up/down, left/right) and three rotational (pitch, yaw, roll)—that enable natural user movement within virtual spaces.

Interoperability: The ability of diverse VR, AR and MR systems and platforms to exchange and use data seamlessly, critical for distributed collaborative and metaverse applications.
