New assessment method

RULA assessment method

  • RULA added as a third method — Rapid Upper Limb Assessment joins NIOSH and KIM-LHC on the method selection screen. Where those two evaluate manual handling, RULA scores working posture itself, so it applies to assembly, machine operation, and screen-based work.
  • Scored from the motion capture data — Upper arm, lower arm, wrist, wrist twist, neck, trunk and legs are derived per frame from the recording and combined through the method's Table A, Table B and Table C lookups into a score from 1 to 7.
  • Posture tasks — RULA uses posture tasks rather than lifting tasks. Each marks one working posture or repeated motion cycle, and the highest-risk frame is found within each one.
  • Automatic muscle use detection — Static posture and repetition are detected from the recording and the trimmed duration, producing separate muscle use scores for the arm/wrist and neck/trunk/leg groups.
  • Leg stability from foot contact and centre of mass — The legs score is derived by measuring how evenly the body's weight sits over the feet that are actually on the ground.
  • Full report output — Score overview, in-depth analysis with the 3D viewer and per-frame graph, findings, and PDF and Excel export, matching the structure of the existing methods.
  • RULA report settings — A dedicated settings page for critical moment detection, the averaged overview, viewport layout, and export templates.

Task naming

  • Describe each task — Tasks can be given a description when you define them, and your own name is used wherever that task appears: the results-page selector, the PDF contents and page headings, and the Excel worksheet tabs. "Lifting from pallet" reads better than "Lifting task 3".
  • Method-appropriate wording — The interface says posture task for RULA and lifting task for NIOSH and KIM-LHC, consistently across screens and exports.

Settings awareness on saved projects

  • Settings changed banner — Opening a saved project whose settings no longer match your current ones now shows an informational banner, instead of leaving the mismatch to surface later at save time. The report is still shown and exported exactly as it was saved.
  • Presentation and analysis separated — The save dialog now groups changed settings into those that can be applied to an existing report and those that are fixed for it. Analysis settings stay with the report so its scores remain comparable over time.
  • Save as New — When saving a reopened project you can store a second copy instead of overwriting, keeping the version you already shared intact.

Reporting & export consistency

  • Shared report styling — PDF and Excel output now draw on common styling and workbook modules across all three methods, so tables, headings and colour bands stay consistent between reports.
  • Thresholds served from the backend — Risk thresholds used for colouring and zone classification are read from the backend configuration rather than duplicated in the interface, removing drift between what is calculated and what is displayed.
  • NIOSH and KIM-LHC refinements — Continued presentation and export improvements to both existing methods alongside the RULA work.

Licensing & workflow polish

  • Licence settings rework — A clearer licence settings page with improved activation and device status presentation.
  • Project loading feedback — An explicit loading state when opening a project from the database, so large assessments no longer appear to hang.
  • Interface polish — Hover tooltips for inline help, plus refinements to shared inputs including the number stepper, date selector, and gender selector.

v1.0.2 adds RULA as a full third assessment method and brings the surrounding save, settings, and export behaviour into line across all three.

Database & quality update

Database & project management

  • Project database introduced — Save, organise, reopen, and continue assessments directly inside Motionprint Ergo. Every saved project retains the full calculation data, custom moments, settings, and subject metadata.
  • Project library workflows — Browse all saved projects in a list view showing title, method, risk level, status, and last activity. Filter by method, status, risk level, or tags to find what you need quickly.
  • Reopen and continue flow — Open any saved project to review findings, edit critical moments, or update metadata. Re-export as a PDF or Excel report at any point before or after saving changes.
  • Project metadata handling — More consistent status and tag behaviour across save and reopen actions. Project status tracks as Draft, In Progress, or Completed.

Settings & privacy consistency

  • Global privacy controls — Operator name, evaluator name, and subject identity display preferences are applied consistently across the interface, reports, and exports.
  • Saved-project consistency — Reopened projects preserve the settings context used when they were originally saved, including branding configuration.
  • Settings comparison flow — When saving a reopened project, if the current app settings differ from the settings stored with that project, a dialog lets you choose which settings to apply before the report is updated.

NIOSH & reporting quality

  • NIOSH presentation refinements — Improved clarity in multiplier display and risk state rendering across report sections.
  • Edge-case handling — Better handling of non-recommended lifting conditions in score presentation.
  • Output robustness — Report JSON and export paths improved for safer handling of problematic numeric values.

Performance & workflow polish

  • Instant first-load behaviour — Project and tag data renders immediately from cache while refreshing in the background, so the project list is visible without delay.
  • Reduced duplicate loading — Better request coalescing in repeated project-list and save-dialog workflows reduces redundant network calls.
  • Smoother save dialog — Existing project values populate immediately when reopening and saving an updated project.

v1.0.1 focuses on reliable project management, consistent reporting behaviour, and a smoother day-to-day analysis workflow.

Initial release

Data input

  • MVNX file import — Direct import of .mvnx files exported from Xsens MVN. Compatible with MVN Awinda and MVN Link suit configurations. No conversion or pre-processing required.
  • Task event definition — Define one or more task events within a recording to segment and assess individual lifting cycles or handling operations.

Assessment methods

  • NIOSH Lifting Equation — Calculates the Recommended Weight Limit (RWL) and Lifting Index (LI) for single-task lifting. Multi-task sessions produce a Composite Lifting Index (CLI) across all defined task events.
  • KIM-LHC — Key Indicator Method for Lifting, Holding and Carrying (BAuA standard). Evaluates physical overload risk based on load weight, duration, posture and working conditions, and outputs a risk score with action level classification.

In-depth analysis

  • 3D motion playback — A full-body avatar replays the captured motion data. Supports 1, 2, or 4 viewports in horizontal, vertical, or quad layouts, each with an independent camera angle and free orbit, pan, and zoom.
  • Body risk indicators — Color-coded markers on key joints update every frame to reflect current biomechanical risk: green (low), orange (medium), or red (high).
  • Score-per-frame graph — Time-series chart of the selected variable with a three-zone color-coded background. Click or drag to scrub to any frame; the avatar and all panels update in sync.
  • Variable selector — Switch the plotted variable to drill into individual ergonomic factors. NIOSH: LI / STLI, horizontal distance, vertical distance, asymmetry angle. KIM-LHC: total score, load handling conditions, trunk twist, load distance, hand height, hand/arm position.
  • Frame insights panel — Shows the numeric value of the selected variable at the current frame, a risk bar indicating where it falls across the three zones, and a zone-distribution pie chart showing the percentage of time spent in each risk zone across the full task.
  • Playback controls — Play/pause at 0.5×, 1×, and 2× speed, with frame range trimming for isolating specific parts of a recording.
  • Critical moments — Auto-detected (peak-score frame, sustained high-risk windows) and user-created (mark the current frame or select a range directly on the graph). Each moment is editable with start/end frames and a description, and appears as a shaded overlay on the graph.

Assessment configuration

  • NIOSH settings — Reference mass (LC) selectable from four standard options (EN 1005-2, NIOSH RNLE / ISO 11228-1:2021, 15 kg, 10 kg); analysis mode switchable between Peak Moment (worst-case across all frames) and Origin/Destination (traditional pickup and placement only); ISO 11228-1:2021 Annex E multipliers individually togglable for two-person lifting, additional physical tasks, one-hand lifting, and extended shift duration.
  • KIM-LHC settings — Fully editable load weight scoring table with separate thresholds for men and women; optional averaged overview across all tasks in the session for consistent load profiles.
  • Auto-generated critical moments — Toggleable for both methods. When enabled, automatically detects the peak-score frame and sustained high-risk windows in the recording.
  • Custom findings sections — Add, remove, rename, and reorder the sections in the report findings page, for both methods independently.
  • Filename templates — Configurable PDF and Excel filename patterns using variables such as {workstation}, {record_date}, and {operator}.
  • Privacy toggles — Optionally hide gender, operator name, or evaluator name from the interface, reports, and exports.

Reports & export

  • PDF export — Fully structured ergonomic report with custom branding — add your own logo and organisation name for client delivery and H&S documentation.
  • Excel export — Underlying assessment data exported to Excel for further analysis, archiving, or integration with your own reporting workflows.

Platform & installation

  • Windows 10 / 11 support — 64-bit installer for Windows 10 and Windows 11. Approximately 80 MB download. Per-user installation — no administrator rights required.
  • Licence activation — Activate with a Motionprint licence key (format: MP-XXXX-XXXX-XXXX-XXXX). Requires an internet connection for initial activation and periodic licence validation.
