SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps users understand and utilize OptiTrack Motive marker data, specifically the Conventional 39 marker set plus project-specific medial markers, for biomechanical analysis without force plates.

Core Features & Use Cases

  • Marker Set Interpretation: Clarifies the purpose and placement of Conventional 39 and custom medial markers.
  • V3D Workflow Feasibility: Guides users on which biomechanical analyses (COM, XCoM, BoS, MoS) are possible without force plates.
  • Data Convention Alignment: Outlines project-specific conventions for file naming, event sources, and coordinate systems.
  • Use Case: A researcher has OptiTrack data and wants to calculate Center of Mass (COM) and Base of Support (BoS) for gait analysis. This Skill provides the necessary context on marker interpretation and analysis feasibility before proceeding to computation.

FAQPage Schema
What is the OptiTrack Conventional 39 marker set used for in biomechanics?▼

The OptiTrack Conventional 39 marker set provides standardized anatomical landmarks for motion capture data interpretation, enabling Visual3D-style biomechanics workflows like calculating Center of Mass and Base of Support.

How do I calculate Center of Mass and Base of Support without force plates?▼

You can calculate Center of Mass, Base of Support, and Margin of Stability without force plates by interpreting OptiTrack marker data to derive the necessary spatial coordinates for biomechanical analysis.

Can I use custom medial markers with the Conventional 39 marker set in Visual3D?▼

Yes, custom medial markers can be integrated with the Conventional 39 marker set to enhance joint axis definition for biomechanical computation in Visual3D workflows.

What biomechanical analyses are feasible using OptiTrack marker data alone?▼

Feasible biomechanical analyses without force plates include calculating Center of Mass, Extrapolated Center of Mass, Base of Support, and Margin of Stability using OptiTrack marker trajectories.

How should I structure file naming and event sources for OptiTrack motion capture data?▼

Project-specific data conventions for OptiTrack motion capture require standardized file naming, designated event sources, and defined coordinate systems to prepare data for biomechanical computation.
