Description

Technical Field

[0001] The invention relates to the technical field of guiding devices for the blind, and in particular to a guiding prompting device for the blind. Background Art

[0002] Blind people are people with visual impairments. Visually impaired people are mainly divided into two categories: blind or totally blind (i.e. blind people), and amblyopia (less than 60% of normal vision). People who are born blind do not have any knowledge of vision, and they usually have no concept of vision. Therefore, there is no visual information in dreams, only other perceptual information. In addition, for people who become blind later in life, as time goes by, their visual cognition ability decreases, and the visual information in their dreams will become less and less, until it is the same as that of people who are born blind. Congenitally blind people also have their own dreams. However, since the information materials in dreams come from the collection and learning of the senses, their dreams are as silent and colorless as their world, and the forms of things are more fragmented.

[0003] Due to visual impairment, blind people do not have an intuitive understanding of many objects, which causes more trouble in daily life. Currently, there is no good device for blind people to guide objects, which cannot facilitate blind people's understanding of some objects. They can only feel them through touch. Since some objects are similar, cognition is very complicated, time-consuming and laborious. Summary of the invention
