NeuroNav

Real-Time Haptic Navigation and Posture Monitor

A non-invasive sensor suite that turns physical proximity and faint detection into a haptic feedback matrix, relaying information to authorized caregivers and HCPs if opted in.

Hardware & the math underneath it

How the sensing works:

ESP32 acts as the main computer, NPU-6050 detects posture changes, and the VL53L0X measures distance. They all work in unison to send data to the ESP32 and outputs via vibration motors.
