The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wearable assistive navigation device for visually impaired individuals designed to provide real-time environmental awareness and hazard detection. The device comprises a miniature camera module embedded within a wearable article such as clothing or an accessory for capturing visual data of the surrounding environment. The captured data is transmitted through a wireless communication module to a mobile computing device where the visual data is processed and analysed to detect objects and environmental conditions relevant to pedestrian navigation. A hazard detection mechanism identifies potential obstacles and unsafe walking conditions. The system further includes a multimodal feedback module comprising an audio output device and a vibration actuator configured to provide navigation guidance and warning alerts to the user. By combining visual sensing, intelligent data processing, and multimodal feedback, the device enables visually impaired users to navigate environments more safely and independently."
