  4. Sensor Fusion, Time-Series & Adaptive Systems

    8 weeks
    • Process IMU, EMG, and force-plate time-series data for movement analysis
    • Build adaptive exercise prescription systems using bandit algorithms or RL basics

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

PostureGuard: Real-Time Exercise Form Classifier

Beginner

Build a webcam-based application using MediaPipe Pose that captures a user performing rehab exercises (wall slides, clamshells, bridges) and provides real-time visual feedback on form quality. Classify movements as correct, mild compensation, or significant compensation based on joint angle thresholds.

RehabBot: LLM-Powered Home Exercise Guide

Intermediate

Create a conversational chatbot using LangChain and OpenAI that guides patients through a prescribed home exercise program. The bot answers questions about exercise technique, adapts instructions based on reported pain levels, and escalates to a human therapist when red-flag symptoms are detected.

MotionTrend: Wearable Sensor Movement Analytics Dashboard

Intermediate

Develop a dashboard that ingests IMU data from consumer wearables (e.g., MetaMotionR, Apple Watch), computes gait parameters (cadence, symmetry, step length), and visualizes recovery trends over a rehab episode. Include anomaly detection for sudden deterioration patterns.

AdaptRx: Contextual Bandit for Adaptive Exercise Prescription

Advanced

Build a contextual bandit system that recommends exercise parameters (type, sets, reps, resistance) based on a simulated patient's session history, pain reports, and progress metrics. Compare the bandit strategy against a fixed protocol using simulated patient trajectories.
