Project Overview
Netra-Link is a smart wearable interface designed for individuals with severe motor disabilities (ALS, Paralysis). It translates voluntary eye-blink patterns into digital commands for Home Automation and Emergency Response.
Unlike standard eye-trackers, this system runs on low-cost hardware (ESP32) and includes a novel "Unconsciousness Detection" algorithm that triggers an alert if the user's eye remains closed for an abnormal duration.
Key Features
- Smart Blink Detection: Ignores natural blinks, toggles appliances on command blinks, and sends SOS alerts on double blinks.
- Unconsciousness monitor: Automatically alerts caregivers if the user is unresponsive.
- IoT Connectivity: Sends push notifications via REST API.
- Menu System: Visualizes selections (Light/Fan/Speaker) via integration with a 16x2 LCD.
