Application Overview
Smart Glasses

With the help of multimodal sensors like visual and aural ones, smart glasses—an inventive wearable technology that blends artificial intelligence (AI) with Internet of Things (IoT) technology—allow intelligent interaction and environmental observation. They offer practical and effective smart services for everyday situations, work, and study, supporting features like voice control, environmental data analysis, and picture recognition. They are the best option for upgrading one's own digital devices.

System Structure

Self-developed Wi-Fi (Wi-Fi SoC) and Bluetooth (Bluetooth SoC) chips are integrated into the Realtek smart glasses solution. These two core chips work together to provide exceptional performance and great integration. The Bluetooth SoC serves as the primary control unit for the system, handling audio processing in addition to hardware and software management. It effectively establishes Bluetooth connections with smartphones and other host devices, providing consumers with a rich interactive experience. High-speed wireless data transfer, multimedia storage, and picture capturing are the main functions of the Wi-Fi SoC. In order to facilitate future development, it also provides a number of standard interfaces for feature upgrades and system expansion.

Main Functional Modules:

  • Bluetooth SoC (Main Controller): Responsible for system management and coordination of various functional modules, enabling audio features such as music playback and voice calls.
  • Wi-Fi SoC: Supports high-definition imaging and high-speed wireless transmission.
  • Touch Control Module: Enables convenient operations such as volume adjustment, music control, and call answering.
  • Ambient Light Sensor (ALS): Detects ambient brightness in real time for intelligent adjustment and safety protection.
  • Camera: Supports real-time high-definition image capture to meet multimedia application requirements.
  • G-Sensor (Gravity Sensor): Detects device orientation and movements, optimizing user control experience and enhancing photography assistance.
  • Storage Module (eMMC, etc.): Used for storing high-quality photos, videos, and various multimedia files.
  • Audio Components (Speaker/Microphone): Supports high-quality voice input and output for various interactive scenarios.

With its highly integrated hardware architecture and a wealth of standard interfaces, this solution significantly improves development efficiency and product scalability. It flexibly adapts to various smart glasses application scenarios and effectively accelerates the mass production and market launch of smart terminal products.
