Research & Validation

Methods should be inspectable before results are trusted.

Biosystems One develops engineering software with explicit intended uses, deterministic verification, documented limitations, and a path toward independent, protocol-specific validation.

Defined scopeKnown ground truth where possibleProvenance retainedLimitations published

01 / Research philosophy

Build knowledge before building claims.

Scientific credibility does not come from polished outputs alone. It comes from a traceable relationship between a question, a method, the data, an analysis, and the limits of the conclusion.

Our software is designed to help qualified users inspect that relationship—not conceal it behind a single score or automated recommendation.

01

Start with the question

Define the knowledge gap, intended population, protocol, measurement plane, task, and decision before choosing a tool.

02

Keep provenance visible

Distinguish manually placed, tracked, constrained, estimated, interpolated, and user-entered observations.

03

Separate verification from validation

Correct software behavior on a known fixture is necessary evidence, but it does not establish fitness for every real protocol.

04

Publish the boundary

Limitations, exclusions, uncertainty, and unresolved validation work belong beside the result—not in hidden fine print.

02 / Validation methodology

A staged evidence model.

Each stage answers a different question. Passing one stage does not substitute for the next.

  1. 01
    Requirements and intended use

    What should the method do?

    Define the users, input conditions, outputs, tolerances, exclusions, and decision context before evaluating performance.

  2. 02
    Deterministic verification

    Does the implementation behave as specified?

    Use known inputs and ground truth to test calculations, thresholds, error handling, provenance, and repeatability.

  3. 03
    Reference comparison

    How does it compare with an independent method?

    Compare against independently digitized recordings, established reference implementations, or qualified manual calculations.

  4. 04
    Protocol-specific validation

    Is it suitable for this population and protocol?

    Evaluate representative tasks, raters, capture conditions, missing data, and failure cases using a pre-defined analysis plan.

  5. 05
    External review and reporting

    Can others examine the evidence?

    Report datasets, methods, version identifiers, uncertainty, deviations, and limitations in a form suitable for independent review.

03 / Intended use

Use depends on product and protocol.

These statements define the current product boundary; they do not replace an institution’s own method review.

Open beta

MotionLab

Intended: Two-dimensional, single-camera analysis of visible landmarks in gait, cycling, occupational movement, teaching, and related technical recordings.

Not intended: Validated three-dimensional motion capture, observation of hidden landmarks, or unreviewed clinical or safety decisions.

Launch preparation

ErgoThrive

Intended: Structured occupational-ergonomics evidence, method inputs, calculation review, revisions, and reporting by qualified professionals.

Not intended: Automatic determination that a job is safe, representative, compliant, or suitable for a worker or population.

Invite-only closed beta

HF Studio

Intended: Controlled workflow and evidence management for qualified medical-device human-factors teams and supervised education.

Not intended: Clinical decisions, automatic safety or regulatory conclusions, certification, QMS replacement, or guaranteed regulatory acceptance.

Catalogue foundation

B1 Ergonomics

Intended: Evidence-aware discovery and review of workplace-equipment records using visible source and evaluation states.

Not intended: Purchasing, supplier fulfilment, automatic product recommendations, compatibility decisions, or claims that demonstration fixtures are evaluated products.

Validation stage

MotionLab Performance

Intended: Private on-device review of supported training movements and cautious longitudinal comparison.

Not intended: Diagnosis, injury prediction, medical decision-making, hidden-landmark measurement, or unreviewed coaching conclusions.

04 / Known limitations

A result is only as strong as its acquisition and assumptions.

These are active engineering boundaries, not hypothetical disclaimers.

MOTION / CAPTURE

Two-dimensional observation

Perspective, camera alignment, lens distortion, scale calibration, variable frame rate, and out-of-plane movement can affect measurements.

TRACKING

Appearance can change

Large displacement, rotation, scale change, deformation, blur, repetitive backgrounds, and occlusion can require manual correction.

AI ASSIST

Landmarks remain estimates

Pose confidence is not anatomical ground truth. Hidden points are not observed, and AI estimates require protocol-specific comparison with manual digitization.

ERGONOMICS

Observation quality governs scoring

Assessment engines cannot determine whether a sampled posture, load, frequency, duration, or task is representative.

SOFTWARE EVIDENCE

Fixtures are not populations

Passing deterministic tests establishes regression behavior for defined inputs; it does not establish general accuracy or external validity.

REGULATORY

No automatic acceptance

No platform output by itself proves safety, compliance, certification, clinical suitability, or submission readiness.

05 / Sample datasets

Small, inspectable fixtures.

These files are synthetic examples for software verification and teaching. They contain no human-subject, clinical, workplace, or customer data.
