GaitPilot Mobile App User Guide

Welcome to the GaitPilot Mobile App! This app is the core data collection and field-testing hub for your biomechanical data. It acts as your portable coaching assistant, processing data in real-time whether you are online or offline.

🎛 The Main Telemetry Dashboard

Main Dashboard (To display this image, save a screenshot of the main dashboard as mobile-dashboard.png in the docs/assets/ folder)

When you open the app and start a session, you are brought to the live telemetry dashboard. This is where the magic happens.

The Sensor Status Grid

At the top of the screen, you will see a grid of connection indicators. GaitPilot supports up to 5 hardware sensors (Bluetooth or WT901 SD CL via import): * Sacrum (Lower Back): The anchor of the system, calculating pelvic tilt, rotation, and overall center of mass. * Left / Right Foot: Calculates Ground Contact Time (GCT), impact forces, and foot clearance. * Left / Right Wrist: Tracks arm drive and cadence to evaluate cross-body synchronization.

Live Biomechanical Gauges

Below the sensor grid, you will find real-time data dials: * Speed & Cadence: Your current GPS-derived speed (MPH) and your step frequency (SPM). * Symmetry Index: A percentage evaluating how balanced your left and right sides are. 100% is perfect; anything below 90% indicates a developing limp or fatigue. * Ground Contact Time (GCT): How long your feet stay on the ground. Crucial for race walkers to ensure they aren't lifting.

🎧 The Audio Persona Coach

You don't need to stare at your phone while running! GaitPilot includes an intelligent AI Audio Coach that speaks to you through your headphones in real-time.

  • Sgt. Major (Tactical): A strict, no-nonsense military cadence caller. Best for rucking and heavy load carriage.
  • Dr. Move (Clinical): A calm physical therapist focused on injury prevention. She will warn you if she detects an asymmetric limp.
  • Coach Speed (Athletic): High energy and motivating. Focuses on your pace, stride efficiency, and keeping your cadence up.
  • Zen Master (Mindful): Focuses on breathing, smooth posture, and relaxed arm swings.

You can change your coach persona at any time in the settings!

📊 The Session Summary Screen

Session Summary (To display this image, save a screenshot of the session summary screen as mobile-summary.png in the docs/assets/ folder)

When you finish your workout (or import an offline SD card session), the app generates a massive, 4-tab summary report:

  1. SUMMARY: Your core metrics. Total miles, average pace, max speed, total steps, and environmental data (temperature/humidity).
  2. METRICS: Deep-dive biomechanics. Look here to see your exact pelvic tilt angles, sacrum oscillation, and arm-swing ranges.
  3. MAP: A fully interactive Google Map showing your exact GPS route.
  4. PATHOLOGY: A timestamped list of every biomechanical error you made during the session (e.g., "00:14:32 - Bent Knee Violation Detected").

Exporting Your Data

At the bottom of the summary screen, you have three powerful options: * SYNC TO DASHBOARD: Uploads the raw data to the Cloud Backend so your coach or clinician can review it on the 3D Avatar web app. * CAST TO TV: Instantly throws the web dashboard up onto your Google TV for a big-screen review session right in your living room. * SHARE: Generates a clean text summary of your workout that you can text or email to anyone.
