Abstract

This paper reviews the literature on mobile assistive devices for visual impaired people, in order to have a clear understanding of the technology and technological progress of helping visual impaired people. In this way, it aims to obtain basic guidelines for analyzing the most relevant equipment to help people with impaired vision and highlight the improvements that can be achieved. The most common device is to integrate different sensors and electronic components into the walking stick to improve their obstacle detection ability. In addition, equipment with cameras, including computer vision algorithms and artificial intelligence technology, has been developed to improve the performance and efficiency of the equipment. Finally, the basic characteristics of the auxiliary system are introduced, and it is found that there is no equipment to meet the needs of users.
