SFR in Action

Evaluate Your System

A five-question educational self-assessment

Answer five plain-language questions about your simulation system's architecture. The tool will show you which classification tier it likely falls into and explain the reasoning. Results are indicative, not official.

Educational Self-Assessment Only

This is not an official SFR evaluation. Results from this tool are educational indicators based on self-reported information and cannot substitute for a formal evaluation conducted with verified evidence. No classification produced here constitutes endorsement, certification, or an official SFR determination.

Question 1 of 5 0%
Question 1 of 5 — Motion Source
Does your platform execute motion commands that are generated directly from your physics model's real-time calculations?
In other words: when the vehicle in your simulation corners, brakes, or accelerates, does the platform receive a command that came directly from that physics calculation — with no filtering, algorithm, or approximation step in between?
Question 2 of 5 — Axis Independence
Do your motion axes operate independently — or are they resolved through a shared mechanical arrangement?
Each direction of movement (forward/back, left/right, up/down, and three rotational directions) should be controlled by its own separate actuator. In a hexapod platform, all six are resolved simultaneously through the kinematics of six shared legs — there is no independent axis at the mechanical level.
Question 3 of 5 — Synchronization
Is the motion platform synchronized to the same real-time physics clock as your visual output?
The motion and visual outputs should respond to the same physics event at the same time. If motion is generated by a separate process with its own timing cycle — or if there is a systematic delay beyond what the hardware requires — the participant receives a mismatch between what they see and what they feel.
Question 4 of 5 — Reference Point
Does your platform reference the vehicle's center of mass for its rotational and translational calculations?
The vehicle's center of mass is the correct reference point for all rotational and translational motion calculations. If the platform uses a different reference — such as the platform's geometric center or a mounting point — the rotational motion delivered to the participant will be mathematically incorrect even if everything else is right.
Question 5 of 5 — Documentation
Is there engineering documentation that traces the signal path from the physics model output to the actuator command?
In a formal SFR evaluation, architecture documentation is essential for verifying the signal path. If documentation does not exist, the classification relies entirely on measured telemetry data — which is the strongest evidence, but requires the system to be instrumented for measurement. Documentation alone (without telemetry) supports a Tier 2 finding.

Your Answers

This is an educational self-assessment only. The result above is based on self-reported information and is intended to help you understand which tier your system likely falls into. It is not an official SFR classification. A formal evaluation requires verified evidence reviewed by an evaluator following the documented SFR evaluation process. For the formal methodology, see Evaluation Process.
