Next, create a new Python file. Name it display_text.py. Open the file and write the following code:

import pygame
pygame.init()
screen = pygame.display.set_mode((320, 240))
pygame.display.set_caption("Smart Glasses")
font = pygame.font.Font(None, 36)
text = font.render("Hello, World!", True, (255, 255, 255))
screen.blit(text, (50, 100))
pygame.display.flip()
while pygame.event.wait().type != pygame.QUIT:
    pass
pygame.quit()

This code initializes Pygame and creates a window. It then displays “Hello, World!” on the screen. You can run this script by typing python3 display_text.py in the terminal.

Adding Advanced Features

Once you have the basic code running, you can add advanced features. One feature is voice recognition. This will allow you to control your smart glasses with voice commands.

First, install the SpeechRecognition library. Type pip install SpeechRecognition in the terminal. Create a new Python file named voice_command.py and add the following code:

import speech_recognition as sr
import pygame

def listen_for_command():
    recognizer = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = recognizer.listen(source)
        try:
            command = recognizer.recognize_google(audio)
            print("You said: " + command)
            return command
        except sr.UnknownValueError:
            print("Sorry, I did not understand that.")
            return None

pygame.init()
screen = pygame.display.set_mode((320, 240))
pygame.display.set_caption("Smart Glasses")
font = pygame.font.Font(None, 36)

while True:
    command = listen_for_command()
    if command:
        screen.fill((0, 0, 0))
        text = font.render(command, True, (255, 255, 255))
        screen.blit(text, (50, 100))
        pygame.display.flip()
        if command.lower() == "quit":
            break

pygame.quit()

This code listens for voice commands and displays them on the screen. If you say “quit,” the program will exit. This is just the beginning. You can add more features to your smart glasses. The possibilities are endless.
