SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill helps analyze movement patterns by visualizing the Center of Mass (COM) position relative to the Base of Support (BOS) over time, crucial for understanding stability and stepping strategies.

Core Features & Use Cases

  • COM vs BOS Visualization: Generates static PNGs and animated GIFs showing COM trajectory overlaid on the BOS rectangle.
  • Stability Analysis: Easily identify when the COM is inside or outside the BOS, indicating stability.
  • Step Comparison: Differentiates between step and non-step trials, with special handling for BOS freeze at step onset.
  • Use Case: Quickly assess if a subject's COM remains within the BOS during a specific trial, or compare stability between different walking conditions.

Quick Start

Generate a BOS+COM XY overlay visualization for the specified subject, velocity, and trial.

FAQPage Schema
How do I visualize Center of Mass relative to Base of Support over time?

You can generate BOS+COM XY overlay visualizations as static PNGs and animated GIFs from replace_V3D output data. This visually tracks the Center of Mass trajectory against the Base of Support rectangle over time.

How does BOS freeze at step onset work for step trials?

The BOS freeze at step onset works by fixing the Base of Support rectangle in place during step trials when the step begins. This allows you to clearly analyze how the Center of Mass moves relative to a stationary BOS during stepping strategies.

Can I compare step versus non-step trials for stability analysis?

Yes, you can compare step versus non-step trials for stability analysis. The visualization differentiates these trial states, allowing you to assess if the Center of Mass remains within the Base of Support across different walking conditions.

Does the COM vs BOS visualization support view rotation?

Yes, the COM vs BOS visualization supports a 90-degree counterclockwise view rotation. This allows you to adjust the orientation of the XY overlay to better analyze Center of Mass trajectory relative to the Base of Support.

What input data formats are needed to generate COM and BOS overlay GIFs?

To generate COM and BOS overlay GIFs, you need specific CSV and XLSM files for input data and trial state. These files provide the replace_V3D outputs required to map the Center of Mass position and Base of Support coordinates over time.
