Virtual Reality Glossary of Terms
Thank you to the Lyndhurst STEM Club for Girls for this resource

Cinematic Reality (CR):
[also referred to as CVR Cinematic Virtual Reality] Envisioned as a type of immersive VR experience where users explore synthetic worlds in 360 degrees, perhaps with stereoscopic views, and hear spatially-directed audio that reinforces the feeling of being in the CVR world

HUD or HMD:
Heads Up Display or Head Mounted Display.

SLAM:
Simultaneous Localization and Mapping

FPS:
Frames per Second. Also referred to as Frame Rate

Degrees of Freedom (DOF):
Usually found in statistics, mathematics, and physics, in the XR realm it refers to tracking of rotational motion. Devices can offer 3 DOF or 6 DOF

3 Degrees of Freedom (example of a device with 3DOF: Oculus Go):

• Pitch – tilting of the head forward and backward on the X axis
• Yaw – turning of the head right and left on the Y axis
• Roll – tilting of the head side to side on the Z axis

6 Degrees of Freedom (example of a device with 6DOF: Oculus Quest):

• The 3 degrees noted above and...
• Sway – move left to right on the X axis
• Heave – move up and down on the Y axis
• Surge – move forward and backward on the Z axis
