Start with the question
Define the knowledge gap, intended population, protocol, measurement plane, task, and decision before choosing a tool.
Research & Validation
Biosystems One develops engineering software with explicit intended uses, deterministic verification, documented limitations, and a path toward independent, protocol-specific validation.
01 / Research philosophy
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.
Define the knowledge gap, intended population, protocol, measurement plane, task, and decision before choosing a tool.
Distinguish manually placed, tracked, constrained, estimated, interpolated, and user-entered observations.
Correct software behavior on a known fixture is necessary evidence, but it does not establish fitness for every real protocol.
Limitations, exclusions, uncertainty, and unresolved validation work belong beside the result—not in hidden fine print.
02 / Validation methodology
Each stage answers a different question. Passing one stage does not substitute for the next.
Define the users, input conditions, outputs, tolerances, exclusions, and decision context before evaluating performance.
Use known inputs and ground truth to test calculations, thresholds, error handling, provenance, and repeatability.
Compare against independently digitized recordings, established reference implementations, or qualified manual calculations.
Evaluate representative tasks, raters, capture conditions, missing data, and failure cases using a pre-defined analysis plan.
Report datasets, methods, version identifiers, uncertainty, deviations, and limitations in a form suitable for independent review.
03 / Intended use
These statements define the current product boundary; they do not replace an institution’s own method review.
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.
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.
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.
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.
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
These are active engineering boundaries, not hypothetical disclaimers.
Perspective, camera alignment, lens distortion, scale calibration, variable frame rate, and out-of-plane movement can affect measurements.
Large displacement, rotation, scale change, deformation, blur, repetitive backgrounds, and occlusion can require manual correction.
Pose confidence is not anatomical ground truth. Hidden points are not observed, and AI estimates require protocol-specific comparison with manual digitization.
Assessment engines cannot determine whether a sampled posture, load, frequency, duration, or task is representative.
Passing deterministic tests establishes regression behavior for defined inputs; it does not establish general accuracy or external validity.
No platform output by itself proves safety, compliance, certification, clinical suitability, or submission readiness.
05 / Sample datasets
These files are synthetic examples for software verification and teaching. They contain no human-subject, clinical, workplace, or customer data.
Ten illustrative schema rows from a synthetic cyclic marker path, including ground truth, estimate, error, frame time, and provenance. This is not the underlying 36-frame regression fixture.
ba0f868c…d14ff830A deterministic input and expected result for the RULA-1993/1.2 calculation engine. The fixture expects a score of 3.
afa91b44…5b8b606These samples are suitable for inspecting schemas and teaching verification concepts. They must not be described as clinical, epidemiological, workplace, population, or product-validation datasets.

08 / Technical notes
Technical notes describe software behavior and engineering decisions; they are not substitutes for independent studies.
Pyramidal Lucas–Kanade estimation, normalized cross-correlation refinement, ambiguity checks, forward–backward rejection, occlusion handling, pose-assist provenance, and known limits.

These are publication priorities—not completed studies, accepted manuscripts, or guaranteed timelines.
Compare calibrated 2D video measurements against independently digitized recordings across defined movement speeds, marker conditions, cameras, and raters.
Evaluate calculation-engine outputs, recommendation wording, and inter-rater workflows with qualified ergonomists using controlled fixtures and representative tasks.
Study whether qualified teams can build and review connected human-factors evidence with fewer missing relationships and clearer decision provenance.
Compare supported on-device movement metrics with independently reviewed reference recordings across defined capture and activity conditions.
Evaluate whether visible evidence and uncertainty states improve equipment-review decisions without implying endorsement or automatic suitability.
Develop openly documented laboratory exercises that separate measurement, uncertainty, software verification, and protocol validation.
