Spatial Anchor
Persistent virtual reference point in physical space, whose position is maintained by the tracking system to keep virtual content fixed relative to the real world.
Environmental Occlusion
Rendering technique that simulates the interaction between virtual objects and real objects, by masking parts of a virtual object that should be hidden by a real object in the foreground.
6DoF Tracking (6 Degrees of Freedom Tracking)
Ability of a system to track the position and orientation of a device in space along three translation axes (x, y, z) and three rotation axes (pitch, roll, yaw).
Temporal Reprojection
Post-processing technique that corrects the position of virtual images between two rendered frames to compensate for user head movement and reduce perceived latency.
Cloud Anchors
Service that allows saving and sharing spatial anchors in the cloud, so multiple users can see and interact with the same virtual content in the same real location.
Environment Meshing
Process of creating a 3D mesh representation of the geometry of a physical space, enabling complex interactions like collisions and light bounces on real surfaces.
Fiducial Marker Tracking
Tracking of predefined visual markers (such as QR codes or ArUco images) to provide an extremely stable and precise reference point for augmented content positioning.
Video Passthrough
Feature that displays a real-time video feed from the front cameras of a mixed reality headset, allowing the user to see their real environment while wearing the device.
Hybrid Mixed Reality (Hybrid MR)
Approach that combines vision-based tracking (VIO) with external sensors (such as room cameras) to improve positioning accuracy and robustness in large spaces.
Multi-user co-localization
Process that synchronizes the understanding of space and anchor positions between multiple devices, allowing users to share a consistent augmented reality experience.
ARKit / ARCore
Development frameworks from Apple and Google respectively, providing basic tools (SLAM, plane detection, light estimation) for creating AR experiences on their mobile platforms.
Deferred rendering in AR
Graphics pipeline technique where geometry, lighting, and material information are calculated separately before being assembled for the final image, allowing for more complex and realistic visual effects.
Raycasting interaction
Interaction method where a virtual ray is projected from the user's viewpoint to detect collisions with real or virtual surfaces, enabling object selection or placement.
Experience persistence
Ability of an augmented reality application to remember the location of virtual content between sessions, so objects remain where they were left.
