Description

Technical Field

[0001] The utility model belongs to the technical field of blind people's travel, and specifically relates to an intelligent blind-guiding cane. Background Art

[0002] As a new type of assistive tool, the smart guide stick is designed to help visually impaired people better integrate into social life and improve their travel safety and quality of life. In today's society, visually impaired people face many difficulties and challenges in their actions, such as avoiding obstacles, identifying the environment and navigating. However, due to the complex traffic conditions, the small number of guide dogs and the high price, they basically do not travel or must be accompanied by their families. Therefore, it is of great significance to research and develop a smart guide stick with functions such as obstacle avoidance, audio playback, anti-fall and intelligent recognition. The research background of the smart guide stick project is mainly to solve the difficulties and challenges faced by visually impaired people in travel, and to improve their travel safety and quality of life by integrating functions such as obstacle avoidance, audio playback, anti-fall and intelligent recognition, so as to help them better integrate into society. This project will integrate advanced sensing technology, voice playback technology, GPS positioning technology and other technical means to realize the comprehensive functions of the smart guide stick, and with the help of the development of modern information technology, provide a more convenient, intelligent and safe guide auxiliary tool.

[0003] Currently, visually impaired people rely on traditional guide sticks when traveling, which have limited functions and cannot meet the needs of the increasingly complex urban environment. Traditional guide sticks mainly rely on touch and hearing for navigation, and have limited access to information about complex traffic environments, road conditions, obstacles, etc., which can easily lead to accidents and difficulties. As a new type of guide aid that integrates advanced sensing technology and information technology, the smart guide stick has more powerful functions and intelligent features, and can provide more comprehensive, real-time and accurate information, thereby helping visually impaired people better understand the surrounding environment, avoid obstacles, avoid collisions, and improve their safety of movement.

[0004] Therefore, the research background of the smart guide cane project is based on a deep understanding of the travel needs of visually impaired people and the promotion of the application of intelligent technology. It aims to provide a more advanced, intelligent and safe guide aid tool to help visually impaired people become more independent, confident and safe in their travel, and improve their quality of life and social integration.
