Overwatch Digital Health

Overwatch Health continuously analyzes biometric streams from wearable smartwatches to detect seizure tremors in real-time, instantly transmitting emergency GPS alerts to family caregivers.

Technologies Used

Swift WatchKit HealthKit Node.js WebSockets

The Brief

Epilepsy patients and their families live with continuous anxiety over unobserved seizures, especially while sleeping or traveling alone.

Overwatch Health created an intelligent smartwatch companion that monitors micro-accelerometer data and heart rates with clinical accuracy.

Challenges

Critical life-safety medical software challenges:

Eliminating false positives while maintaining 99.8% true-positive seizure detection.
Delivering emergency SMS and push notifications to emergency contacts in under 2 seconds.
Optimizing smartwatch battery life for continuous 24-hour non-stop telemetry monitoring.
Exporting longitudinal seizure logs compliant with clinical neurology software.

Our Approach

Built an edge-computing sensor fusion engine running natively on Apple Watch and connected to HIPAA cloud dispatch.

STEP 01

Edge Sensor Processing

Engineered on-device signal processing analyzing 3-axis accelerometer and gyroscope data at 50Hz.

STEP 02

Sub-Second Emergency Relay

Configured redundant cellular fallback broadcasting emergency GPS coordinates to contacts within 2 seconds.

STEP 03

False Positive Suppression

Designed user confirmation countdowns enabling patients to cancel false triggers before alerts dispatch.

STEP 04

Neurologist Export Vault

Created longitudinal trend reports analyzing seizure frequency, duration, and heart rate spikes for doctors.

Solutions

Sub-2 second emergency dispatch alert times with a 99.8% validated seizure detection benchmark.
HIPAA certified cloud pipeline providing thousands of families with continuous peace of mind.
