Visually impaired people face many challenges, including difficulty in navigating their environment and accessing information from their surroundings. Though a typical walking stick helps to navigate, it cannot meet the safety monitoring and guidance requirements of visually impaired people. To provide ease in their livelihood and to help them walk more confidently, we propose an electronic device called The Smart cane, which helps people find obstacle-free paths in their environment and will also aid in providing the description of the objects in front of them when requested. The smart cane offers a concise description of the user’s path when the dedicated button is activated. Concise information is delivered to the user through audio for ease of understanding. The proposed Smart cane is feasible and efficient for daily use. It integrates an ESP 32, ultrasonic sensors, a camera, a GPS (Global Positioning System) module, a GSM (Global System for Mobile communication) module, speaker and touch sensors. Testing the reliability and integrity of the system shows effectiveness in detecting obstacles, image description, audio feedback, and navigating an obstacle-free path, thereby improving mobility, safety, and confidence in their life as the testing yielded a BLEU score of 0.38, METEOR score of 0.31 and ROUGE score of 0.59 in image captioning. It also gives out a buzzer noise when an obstacle is present at a distance less than 30 cm from the cane.

摘要

Visually impaired people face many challenges, including difficulty in navigating their environment and accessing information from their surroundings. Though a typical walking stick helps to navigate, it cannot meet the safety monitoring and guidance requirements of visually impaired people. To provide ease in their livelihood and to help them walk more confidently, we propose an electronic device called The Smart cane, which helps people find obstacle-free paths in their environment and will also aid in providing the description of the objects in front of them when requested. The smart cane offers a concise description of the user’s path when the dedicated button is activated. Concise information is delivered to the user through audio for ease of understanding. The proposed Smart cane is feasible and efficient for daily use. It integrates an ESP 32, ultrasonic sensors, a camera, a GPS (Global Positioning System) module, a GSM (Global System for Mobile communication) module, speaker and touch sensors. Testing the reliability and integrity of the system shows effectiveness in detecting obstacles, image description, audio feedback, and navigating an obstacle-free path, thereby improving mobility, safety, and confidence in their life as the testing yielded a BLEU score of 0.38, METEOR score of 0.31 and ROUGE score of 0.59 in image captioning. It also gives out a buzzer noise when an obstacle is present at a distance less than 30 cm from the cane.
