What is Mixed Reality(MR)?
Mixed reality (MR) is a technology that merges digital content with the physical world in a way that allows virtual and real objects to interact. Unlike augmented reality, which primarily adds a flat 2D or surface-level 3D overlay on top of a real-world view, mixed reality anchors digital objects into the physical environment so they respond to real-world context, appearing behind real objects, reacting to physical surfaces, and maintaining their position as you move around them.
Devices like the Meta Quest 3 (in MR mode) create this effect using spatial mapping and depth sensors that understand the geometry of the physical room, letting the system place virtual content accurately within it. The defining experience of MR is that virtual content feels spatially present in your real environment. It occupies space in a way that basic AR does not.
How MR Differs from AR and VR
MR sits on a spectrum between AR and VR, and the distinctions matter practically for how and where it gets deployed.
The distinction between AR and MR matters practically, not just technically. In basic AR, such as most phone AR apps, digital content appears to float in front of the camera feed but doesn't truly interact with the physical environment. It doesn't go behind a real object; it doesn't sit stably on a real surface as you move. In MR, the digital content is spatially registered to the real world with sufficient precision that it behaves like a real object occupying physical space.
Compared to VR, which replaces the real world entirely, MR keeps you physically present in your environment while adding digital elements. This is particularly valuable for industrial applications where workers need to maintain awareness of real physical hazards while receiving digital guidance. A technician in VR is disconnected from the real equipment; a technician in MR sees both simultaneously.
MR in Industrial and Enterprise Settings
MR has found strong traction in industrial environments precisely because it keeps workers connected to physical reality while layering in the digital context they need.
Training on Virtual Equipment in Real Space
MR training lets learners interact with virtual replicas of real equipment placed in their actual work environment. A trainee can practise disassembling a virtual pump mounted in front of the real pump housing, building procedural memory tied to the actual physical space they'll work in rather than a generic virtual environment.
This spatial alignment between training and real work context has been shown to improve transfer of learning, with skills practised in the right spatial context transferring more reliably to the actual task.
Design Review and Collaboration
Engineering teams can view a full-scale 3D model of a product or facility overlaid in a real room, walking around it, measuring dimensions, annotating specific features, and discussing changes while everyone present or connected remotely sees the same virtual object in shared space.
This is significantly more effective for spatial decision-making than reviewing the same design on a 2D screen, particularly for decisions about how a product will fit within a real physical environment.
Maintenance and Operational Support
Technicians using MR headsets can see digital overlays on real equipment, highlighting the component to be serviced, showing torque values, and displaying step-by-step procedures anchored to the physical location where the work happens.
Remote experts can draw annotations into the technician's view via a shared MR session, effectively pointing at real objects in the physical environment from thousands of miles away. This combination of spatial context and remote expertise is one of the most practical applications of MR in industrial settings.
Current Hardware
Microsoft HoloLens 2 was the dominant enterprise MR device for several years, but Microsoft confirmed in early 2025 that it is discontinuing the hardware line, having ended production in October 2024, with software support continuing through December 2027.
The main alternatives now are Magic Leap 2, Meta Quest 3, and Apple Vision Pro. Magic Leap 2 is the closest like-for-like replacement, a purpose-built enterprise headset with optical see-through displays and a lighter form factor, used across industrial, healthcare, and manufacturing settings. Meta Quest 3 offers the best overall balance of capability and cost for organisations starting out with MR, while Apple Vision Pro leads on visual fidelity, making it better suited to design review and engineering visualisation than frontline industrial use.
The choice between them largely comes down to use cases. Optical see-through devices like Magic Leap 2 keep workers fully aware of their physical surroundings, which matters in industrial environments. Video passthrough headsets like Meta Quest 3 and Vision Pro deliver stronger visual integration with virtual content, which suits training and design work.
Considerations for MR Adoption
The most consistent factor limiting MR adoption is content development investment. The headset hardware is capable; building MR applications that are genuinely useful for a specific workflow requires design, development, user testing, and iteration.
Organisations that see strong results typically start with one high-value use case, a specific maintenance procedure or training scenario, rather than attempting a comprehensive MR programme from the outset. Starting narrow, proving value, and expanding is the approach that generates both organisational buy-in and the content development experience needed to do it well at scale.
