XR glasses glossary
- 3DoF
- Three degrees of freedom: tracks head rotation (yaw, pitch, roll) but not movement through space.
- 6DoF
- Six degrees of freedom: rotation plus position, usually using cameras.
- 0DoF
- A fixed screen that moves with your head. Best in vehicles.
- Birdbath optics
- A compact design where a display above the lens reflects off a curved combiner. Common in display glasses.
- Prism optics
- An alternative combiner design used by some newer glasses that allows a wider FOV.
- DP Alt Mode
- DisplayPort Alternate Mode: lets a USB-C port carry video. Needed for a direct connection to the glasses.
- Diopter dial
- A built-in focus adjustment for nearsighted users.
- Edge fade
- Gradually darkening the outer edge of the image so soft corners are less distracting.
- Electrochromic dimming
- Lenses that darken electronically to block outside light.
- Eyebox
- The zone where your eye can be and still see the full image sharply.
- FOV
- Field of view: how large the image appears, given as a diagonal angle (e.g. 46°, 50°, 58°).
- Half SBS
- Side-by-side 3D squeezed into one normal-width frame. Full SBS keeps full width per eye.
- Gyro drift
- Slow wandering of a head-tracked screen caused by accumulated sensor error.
- IPD
- Interpupillary distance: the distance between your pupils.
- Lead eye
- In Complete VR Studio's depth effect, the eye whose image is enlarged or tilted.
- Micro-OLED
- The tiny, high-density OLED panels used in most display glasses.
- Per-eye
- Settings applied to the left or right eye independently.
- Recenter
- Resetting a head-tracked screen to straight ahead (Ctrl+Alt+R in Complete VR Studio).
- Refresh rate
- How many times per second the display updates, e.g. 60, 90 or 120 Hz.
- SBS
- Side-by-side: a 3D format with left and right images next to each other, 3840×1080 on most glasses.
- Stretch / curvature
- Scaling and bending the image to fit the optics or to match the two eyes.
- Vertical disparity
- An up/down offset between the eyes. Even small amounts are uncomfortable.
