What does HMD stand for?
head-mounted display
What technology fully immerses users in a digital environment?
virtual reality
This 3D light-based projection appears to float in space and can be viewed from multiple angles without a headset.
hologram
What common XR devices track hand movement and input?
hand controller / data glove
What term describes vibration or touch responses from a device?
haptic feedback
frames per second
What reality blends and allows interaction between real and virtual objects?
mixed reality
What performance metric measures delay between user action and system response?
latency
This category of technology—such as smartwatches, AR glasses, and VR gloves—is designed to be worn on the body while providing digital interaction.
wearables
What haptic method creates physical resistance to simulate weight or texture?
force feedback
What does FOV stand for?
Field of view
What reality overlays digital content on top of the real world?
augmented reality
This capability allows an XR system to understand its surroundings, including surfaces, boundaries, and object positions.
spatial awareness
This term describes a persistent, shared digital universe where users can work, play, and interact through avatars.
metaverse
This type of haptic sensation stimulates the skin—often through vibration—to simulate touch in XR experiences.
tactile feedback
What does XR stand for?
extended reality
What word describes the feeling of being “inside” an XR experience?
immersion
This mapping information describes where objects or locations exist on Earth’s surface, forming the foundation for AR navigation and location-based apps.
geospatial data
This patterned visual reference—often a black-and-white square—is used in AR to help the system identify position and orientation in space.
fiduciary marker
What term describes a touch-enabled panel that simulates textures or patterns?
surface haptics
What does DoF stand for?
degree of freedom
What term refers to the computer-generated world users explore in VR?
Virtual environment
What graphics technique renders high resolution only where the eyes are focused?
foveated rendering
Uses two microphones to simulate natural hearing for immersive sound.
Binaural audio/rendering
What technology generates touch sensations without requiring physical contact?
mid-air haptics
