Assistive Smart Glasses for Visual Impairment and System with Real-Time Image Recognition

Strategic Insights -

A groundbreaking patent by InnoSpire Technology Limited, a Hong Kong-based company, has been published online on October 14, 2025, for assistive smart glasses that use real-time image recognition to assist visually impaired users. The patent, filed on November 16, 2021, describes a system and control method for the smart glasses, which integrate a microprocessor, bone conduction headphone, wireless communication module, and camera lens. This innovative technology enables users to capture and send images to a mobile terminal for real-time recognition, providing assistance in everyday tasks.

Key Takeaways:

  • The assistive smart glasses system, developed by InnoSpire Technology Limited, includes a glasses body integrating various components such as a microprocessor, bone conduction headphone, and wireless communication module.
  • The system allows users to capture images in real-time and send them to a mobile terminal for recognition, which can be performed by a convolutional neural network model on the mobile terminal.
  • The patent provides for an option to connect the assistive smart glasses with a service terminal, enabling direct real-time communication between the volunteer and the visually impaired user for manual assistance.
  • The system includes a character recognition module for recognizing characters in the image and sending a recognition result to the assistive smart glasses.
  • The control method of the assistive smart glasses system involves four steps: capturing an image, preprocessing the image using a convolutional neural network model, comparing the preprocessed image with digital target default values, and sending a result to the assistive smart glasses or uploading the image to a server for manual recognition.
  • The technology has the potential to revolutionize the lives of visually impaired individuals by providing real-time assistance in everyday tasks.
