Flashcards
0/20
Gaze Interaction
Gaze interaction in AR systems involves tracking the user's point of gaze to interact with virtual elements.
Gesture Recognition
Gesture recognition allows users to control AR applications through hand or body movements.
Voice Commands
AR systems can use voice recognition to receive and interpret spoken commands from users.
Haptic Feedback
Haptic feedback in AR provides tactile responses to enhance the realism of virtual interactions.
Marker-based Tracking
Marker-based tracking detects specific visual cues in the environment to overlay digital content accurately in AR.
Markerless Tracking
Markerless tracking uses sensors to understand the environment and place virtual objects without predefined markers.
Natural Feature Tracking
Natural feature tracking recognizes specific patterns or objects in the real world to align virtual objects appropriately.
Multi-User Interaction
Multi-user interaction in AR enables several participants to engage with shared augmented content simultaneously.
Spatial Audio
Spatial audio in AR provides 3D sound that changes with the user's orientation and location relative to virtual objects.
Head-Mounted Displays (HMDs)
HMDs are worn on the head to provide an immersive AR experience with visual, auditory, or even haptic feedback.
Handheld AR
Handheld AR utilizes mobile devices such as smartphones or tablets to display AR content through their screens.
Projection-based AR
Projection-based AR projects digital images onto physical surfaces in the real world, allowing interaction with those projections.
Wearable Augmented Reality
Wearable AR includes devices like smart glasses and AR contacts that integrate AR directly into the user's field of vision.
Context-Aware AR
Context-aware AR adapts the content and interactions based on the user's current context such as location, time, or activity.
6DoF (Six Degrees of Freedom)
6DoF refers to the ability to track both position and orientation in 3D space, essential for a fully immersive AR experience.
AR Cloud
The AR Cloud is a persistent digital layer that is aligned with the physical world, which can be shared and accessed by multiple users.
Augmented Reality SDKs
AR SDKs provide tools and libraries for developing AR applications, including features like tracking and image recognition.
Light Estimation
Light estimation in AR allows virtual objects to cast shadows and have lighting consistent with the real-world environment.
AR Interaction Design
AR interaction design focuses on creating intuitive user interfaces and experiences in augmented reality applications.
Object Recognition and Tracking
Object recognition and tracking enable AR systems to identify and follow the movement of specific objects in the real world.
