Prediction Latency
Prediction horizon in milliseconds from pose-measurement timestamp to target display timestamp on the same clock.
Description
Prediction horizon in milliseconds from pose-measurement timestamp to target display timestamp on the same clock.
Prediction Latency is a focused tool for the following task. Prediction horizon in milliseconds from pose-measurement timestamp to target display timestamp on the same clock. It reports Prediction Milliseconds from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Prediction Latency
Use this virtual-reality calculation for a first-order display, optics, tracking, rendering, or latency estimate when all stages and units are explicitly defined.
- Measurement Milliseconds (ms)
- Required number in ms.
- Target Display Milliseconds (ms)
- Required number in ms.
The cited overview of Virtual reality sickness supplies background for the terminology and domain context used by this tool.1
How Prediction Latency works
Prediction horizon in milliseconds from pose-measurement timestamp to target display timestamp on the same clock. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Prediction Milliseconds (ms)
- Returned number in ms.
Limitations and assumptions
- Lens calibration, per-eye geometry, display scanout, asynchronous pipelines, tracking filters, workload variation, user anatomy, and device firmware can make measured VR behavior differ from a serial model.
- Measurement Milliseconds must be at least 0.
- Target Display Milliseconds must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
Validate the estimate on the target headset with calibrated motion, optical, frame-timing, and latency measurements under a representative workload.
