Shanghai Jiao Tong University Develops AI Navigation for Visually Impaired

Shanghai Jiao Tong University has developed an AI-powered wearable navigation system for the visually impaired. The device uses cameras and AI algorithms to identify obstacles and guide users. It transmits information through bone conduction headphones and tactile feedback on the wrist. The system, developed by Professor Gu Leilei, includes glasses with cameras, electronic skin, and a mini-computer. An infrared detector addresses camera limitations in low light, providing distance and height data. The device responds in 200-300 milliseconds, mimicking human reaction time. Complementing the device are smart insoles and a VR training platform. These features allow users to practice navigation in a virtual environment. The research, currently in its early stages, was published in Nature Machine Intelligence.
