Voice Vision Glass: A Smart Assistive Eyewear for the Blind and Visually Impaired

According to the World Health Organization, there are currently about 45 million blind people worldwide. In addition, 135 million people have low vision. This paper aims to assist blind people and visually impaired people to navigate more independently. This glass uses advanced technologies, including Raspberry Pi 4 and APIs like Gemini, GTTS (Google Text-To-Speech) and a Pre-trained model from Hugging Face to provide assistance and improve the quality of life of visually impaired people. The glass utilizes voice interaction for interactive commands and assistance and then APIs process the data to generate meaningful audio feedback. The Raspberry Pi 4 is the central processing unit, and it combines hardware components and software applications to provide smooth operation. Key elements include a microphone for voice input, speakers/earphones for audio feedback and Raspberry Pi 4 for processing the data received. The device also uses a rechargeable battery for long-term usage. By combining all these, this device can provide a more reliable and efficient way to improve the lives of visually impaired people and help them in different ways from day-to-day activities to activities requiring assistance.
