Prototype Design

We used theOnshape platform to design the glasses' shape, where several versions were created, and we reached this final design.

Identifying the Tools and Equipment Needed for Project Implementation

Component
Raspberry Pi 4/5 (4GB+)
Pi Camera v2 or USB Webcam
HC-SR04 Ultrasonic Sensor
Tactile Push Button
10kΩ Resistor
Breadboard + Jumper Wires
Speaker or Bone Conduction Headphones
Power Bank (5V 2A+)
MicroSD Card (32GB+)
Glasses frame designed to enclose the equipment inside
Visual Studio Code - Python

Work Plan

Hardware Connections

📷 Camera

CSI port (for Pi Camera) or USB port

🔊 Audio

Use 3.5mm jack or USB speaker

📏 HC-SR04 Sensor

VCC → 5V
GND → GND
Trig → GPIO 23
Echo → GPIO 24

🔘 Button

Leg 1 → GPIO 17
Leg 2 → GND
10kΩ Resistor between GPIO 17 and GND

🧠 Software Setup

Run the following commands to install required libraries:
sudo apt update
sudo apt install espeak tesseract-ocr
pip install opencv-python pytesseract pyttsx3 RPi.GPIO
