Knowra Augmented reality Augmented reality Augmented reality overlays computer-generated information or objects onto a view of the physical world in real time, linking digital content to a user's surroundings.
Simultaneous localization and mapping : A method by which a device builds a map of an environment while estimating its position within that map. AR systems use it to track device movement and anchor content to physical locations.
Spatial registration : The alignment of coordinate systems so representations of the same objects or locations coincide. Accurate registration keeps virtual content aligned with the physical scene.
Pokémon Go : A mobile game in which players find and capture Pokémon at real-world locations using augmented reality features. Its location-based play made AR familiar to a mass audience.
Virtual reality : A technology that immerses users in a computer-generated environment, typically replacing their view of the physical world. VR substitutes a simulated environment, while AR keeps the physical world in view.
Wearable technology : Electronic devices designed to be worn on the body, often sensing or displaying information. Head-worn AR makes computing continuous and hands-free, extending wearable technology.
Visual-inertial odometry : A method that estimates motion by combining camera images with measurements from inertial sensors. It helps AR devices maintain stable tracking when visual features are sparse or motion is rapid.
Coordinate system : A framework of reference points and axes used to specify positions in space. AR tracking and rendering depend on relating device, world, and display coordinates.
Microsoft HoloLens : A mixed-reality headset developed by Microsoft with see-through displays and spatial sensing. It illustrates hands-free AR for design, training, and industrial work.
Mixed reality : A spectrum of experiences in which physical and digital objects coexist and can interact spatially. The term often emphasizes persistent spatial interaction beyond simple overlays.
Surveillance : The systematic observation of people, places, or activities, often through data-collection technologies. Camera-equipped AR devices raise questions about recording and observing others in shared spaces.
