Problems solved by technology

[0002] For a long time, due to lack of vision or loss of vision, visually impaired people cannot normally use the visual indicators of various common public facilities, so it is difficult for them to enter unfamiliar environments without the assistance of others
At present, the only blind road specially provided to solve the walking problem of blind friends
Sound instructions, such as broadcasting, are a feasible way for ordinary public facilities to facilitate the public. Both blind and normal people can use them, but they are not suitable for large-scale, large-scale, and frequent use. It will be detrimental to blind friends to accurately listen to useful sounds
