Design of a guiding cane for human-computer interaction using sensors

Human society is a comprehensive group structure. As a special group, blind people occupy a large proportion in society. It is inevitable and very difficult for blind people to walk alone in their life. First, they are easy to lose their way at intersections. Second, some imperceptible obstacles will hurt them. Finally, the Blind Way occupied will make their walk more difficult. However, with the progress of computer technology, there are more and more products that can help the blind to travel, such as wearing the obstacle warning clothing on the body of the blind, or the obstacle recognition device in the form of glasses. However, most of the products are not only very complex in use, but also change the original travel habits of the blind, making them have a kind of resistance. This research is based on the concept of human-centred design from the perspective of helping the blind, with the focus on not changing the original habits of the blind, using the concept of barrier-free design as a guideline to discover the travel needs of the blind in their daily lives, and using the sensors as the collection end, and using the computer and the device for interaction, in order to complete the design of mobility products for the blind. It is hoped that the design and research in this paper will help the development of guide products and serve as a reference for future research on such products, and that more designers will pay attention to these visually impaired people and give them more and better designs in the future.
