Overview

About the Project

The Smart Spectacle is a low-cost, wearable assistive device designed to help visually impaired individuals navigate safely and independently. It improves upon traditional white canes by detecting head-level obstacles and sudden road curves in real time

Powered by an Arduino UNO, the system uses an ultrasonic sensor and a gyroscope to continuously monitor the user's surroundings. When it detects a hazard or direction change, it immediately warns the wearer using both vibration motors and voice alerts

Features

What It Does

⚠️
Real-Time Obstacle Detection

Uses an ultrasonic sensor to continuously measure the distance to objects in front of the user, warning them of hazards at head level

🎢
Curve and Slope Detection

Utilizes a gyroscope sensor to detect sudden changes in head movement or direction, which indicates a road curve, turn, or slope

⚙🚨
Dual Alert System

Provides immediate feedback to the user through a combination of voice alerts via an earphone/speaker and tactile feedback from a vibration motor

👓
Hands-Free Wearability

Designed as a lightweight spectacle frame, offering a hands-free, low-cost alternative to traditional white canes for independent navigation
