Controller Latency
Serial controller input latency from scan, transport, and processing stages.
Description
Serial controller input latency from scan, transport, and processing stages.
Controller Latency is a focused tool for the following task. Serial controller input latency from scan, transport, and processing stages. It reports Latency Milliseconds from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Controller 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.
- Scan Milliseconds (ms)
- Required number in ms.
- Transport Milliseconds (ms)
- Required number in ms.
- Processing 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 Controller Latency works
Serial controller input latency from scan, transport, and processing stages. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Latency 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.
- Scan Milliseconds must be at least 0.
- Transport Milliseconds must be at least 0.
- Processing 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.
