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.
