Inspiration

We were deeply inspired by one of our close friends who faces the daily challenge of living with seizures. His parents, with good reason, worry about his safety whenever he goes out alone, since seizures strike unexpectedly and without warning. The greatest danger lies in the risk of falling and suffering serious injuries during an episode. Just as concerning, seizures lasting more than five minutes can result in long-term brain damage, making timely intervention absolutely critical. Even bringing in a small sense of autonomy into patients' lives makes a big difference.

What it does

Using a Brain-Computer Interface (BCI), we capture the brain wave activity of individuals with epilepsy and process that data through our platform. Our machine learning model, trained on thousands of data points, can accurately predict whether a seizure is likely to occur within the next 1-2 minutes. While this may seem like a short window, it provides patients with crucial time to sit down, prepare themselves mentally, and move away from sharp objects or other potential hazards. The system sends an alert via text message to the patient and also notifies their caretaker, enabling timely precautions and added safety.

How we built it

Phase 1: Research seizure patterns, tech stack (Flask, React, XGBoost, WebSockets, Chart.js). Phase 2: EEG simulator + feature extraction pipeline. Phase 3: Real-time backend + WebSocket communication. Phase 4: React dashboard for monitoring. Phase 5: Alerts via Twilio + comprehensive testing.

Challenges we ran into

Latency: Optimized feature extraction → <50ms per detection. False positives: → reduced rate to <2%. WebSocket drops: Auto-reconnect → 99.9% uptime. UI complexity: Simplified with UX principles.

Accomplishments that we're proud of

97.0% accuracy, <50ms latency, <2% false positives. Intuitive dashboard + WhatsApp alerts. Modular, scalable, and secure architecture.

What we learned

Tech: Start simple, optimize for real-time, test constantly. Team: Clear requirements, early feedback, strong collaboration. Personal: Problem-solving and HIPAA compliance.

What's next for SeizureSense

Short-term: Mobile app, cloud backup, advanced visualization. Long-term: Clinical validation, EMR integration, predictive AI, personalized care.
