be.glasses are a tool that helps blind/partially visually impaired individuals lead an independent life. Imagine if a person could identify objects in their day-to-day life and understand the value of currency notes. That creates a profound impact.

Hardware Architecture

  • Raspberry Pi Zero 2W: A single-board computer (SBC) with a 1GHz quad-core CPU and 512MB RAM. Runs machine learning algorithms and processes images.
  • Pi Camera v1.3 - 5MP: Captures real-time images of the environment and feeds data into computer vision models.
  • Battery Management System: 1000mAh Li-Po Battery + BMS Chip + Boost Converter. Powers the glasses and steps voltage up to 5V safely.
  • Headset & Microphone: Bluetooth headphones for Text-to-Speech (TTS) output, and a MAK Wireless USB Mic to capture voice commands.
  • 3D Printed Chassis: Made of PET filament ensuring a lightweight and durable structure that houses all components in a wearable format.
3D Printed Working Model

System Principles

Optics & Vision

The camera captures visual data, which is processed by the Raspberry Pi using computer vision algorithms (Efficient DET & custom ML models). Pytesseract and Google Vision handle Optical Character Recognition (OCR) to extract text.

Acoustics & UI

Controlled entirely via voice commands using Speech Recognition. The results are converted to audio using Text-to-Speech (TTS) algorithms and played through a Bluetooth headset.

Applications of the Device

Object Recognition

Provides audio descriptions of over 100+ real world objects, making it incredibly useful for day-to-day object recognition, social interaction, and safety.

Support & Safety

Enabled by a human presence detection algorithm, it alerts the user if a human enters or is present in the same room, potentially saving the individual wearing the device in emergencies.

Accessibility

Since most public spaces are not designed with visually impaired individuals in mind, the text extraction algorithm drastically improves the overall public experience, fostering societal inclusion.

Conclusion & Future Work

As we wrap up, we’ve designed detailed 3D models for the glasses, sourced core electronics, and significantly progressed our software for object detection and navigation algorithms.

“Together, we’re not just building glasses; we’re building independence.”
