Use this virtual-reality calculation for a first-order display, optics, tracking, rendering, or latency estimate when all stages and units are explicitly defined.

Capture Milliseconds (ms)

Required number in ms.

Computation Milliseconds (ms)

Required number in ms.

Transport 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]

Serial tracking pipeline latency from sensor capture, pose computation and transport. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Tracking Milliseconds (ms)

Returned number in ms.

• 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.
• Capture Milliseconds must be at least 0.
• Computation Milliseconds must be at least 0.
• Transport Milliseconds must be at least 0.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Validate the estimate on the target headset with calibrated motion, optical, frame-timing, and latency measurements under a representative workload.

• Eye Tracking Latency Ms

  Serial eye-tracking latency from exposure, gaze inference, and output transport.

• Controller Latency

  Serial controller input latency from scan, transport, and processing stages.

• Haptic Feedback Latency

  Serial haptic latency from command processing, transport, and actuator onset.
