What is VR, AR, MR, and XR?
Virtual Reality (VR):
Enclosed experience that creates a perception of reality
Augmented Reality (AR):
Computer generated content on top of real world
Mixed Reality (MR):
Virtual objects interact with real objects and spaces
Extended Reality (XR):
The over-arching umbrella that includes VR, AR, and MR.
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.
Simultaneous Localization and Mapping
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
