What is mixed reality and how is it different from augmented reality?
The practical difference between AR and MR is the depth of real-world integration. Standard augmented reality overlays digital content on a camera view of the real world the virtual objects are displayed on a 2D screen and do not truly interact with the physical space (they cannot be occluded by real objects, they do not understand the geometry of the environment). Mixed reality as demonstrated by Microsoft HoloLens uses real-time depth sensing and spatial mapping to understand the 3D structure of the environment: holograms can be occluded by real physical objects (a holographic display disappears behind a real table), anchored precisely to real surfaces, and persistently placed across sessions and multiple users. Apple uses the term spatial computing for Vision Pro. Microsoft uses mixed reality for HoloLens. Both represent a more sophisticated integration between digital and physical than standard mobile AR.
What is Azure Spatial Anchors and why is it critical for enterprise MR?
Azure Spatial Anchors is a cloud service that enables holographic content to persist in precise physical locations across sessions and multiple headsets. Without spatial anchors, each HoloLens session starts fresh holograms placed in the previous session are lost, requiring manual repositioning. With Azure Spatial Anchors: a maintenance instruction overlay anchored to a specific piece of equipment is automatically rediscovered and repositioned to exactly the same location in the next session. The HoloLens scans the environment, matches visual features to the stored anchor point in Azure, and restores the hologram position. For enterprise deployments with multiple technicians, the anchor positions are shared all HoloLens devices see the same holograms on the same physical equipment. Azure Spatial Anchors makes persistent, shared holographic content practical for industrial and enterprise MR deployments.
What is the business case for HoloLens 2 vs smartphone AR?
HoloLens 2 advantages over smartphone AR for industrial and enterprise use: hands-free operation (a field technician cannot hold both tools and a phone HoloLens displays instructions in the field of view, operated by voice and hand gestures), persistent world anchors (holograms stay anchored to equipment across sessions and users smartphone AR requires holding the phone up continuously), 26-DOF hand tracking (natural interaction compatible with industrial gloves), and durability (designed for industrial environments drop resistance, IP tested, compatible with safety helmets and eye protection). The cost trade-off: HoloLens 2 costs $3,500/device. The ROI case: hands-free maintenance instructions reduce procedure time by 20-25% and error rates significantly on complex equipment. For maintenance operations on high-value assets where errors are costly, the productivity gain justifies the hardware investment. HoloLens 2 is not appropriate for consumer-facing AR or applications where the use case does not require hands-free operation.
What is visionOS and how is Apple Vision Pro different from HoloLens?
visionOS is Apple's operating system for Apple Vision Pro launched in 2024 at $3,499. Applications run in Shared Space (real environment with floating app windows and 3D volumes spatial desktop) or Full Space (immersive environment application controls the entire display). Vision Pro advantages over HoloLens 2: micro-OLED displays with significantly higher resolution and colour accuracy (digital content looks photorealistic), full-colour high-quality passthrough video (more immersive than HoloLens' lower-resolution passthrough), eye+finger pinch interaction (subtle, social no hand gestures visible to others), and Apple ecosystem (Swift/SwiftUI, TestFlight, App Store distribution). HoloLens 2 advantages: more mature enterprise ecosystem (Dynamics 365 Remote Assist, Azure Spatial Anchors, MRTK production-proven across thousands of enterprise deployments), better suitability for industrial environments with safety equipment, and a wider field of view for large holograms. ClickMasters builds for both HoloLens 2 for established enterprise and industrial deployments, Vision Pro for forward-looking spatial computing applications where display quality and interaction design are differentiators.
