Generally, for visually impaired people, they depend on their own senses when they want to find public facilities such as public buildings, bus stops, subway stations, and communication facilities, or they need help from guide dogs or the general public. In particular, visually impaired people are significantly less aware of their surroundings and circumstances than other people with disabilities, so they are inevitably shrinking psychologically and feel anxiety and nervousness about an unfamiliar environment.

To solve this problem, the convenience facilities for the visually impaired, which are installed on the road or each facility, are Braille blocks. The braille block is divided into a point block and a linear block. The point block is installed at a distance of 0.3 meters in front of a stairway, a lift for disabled, a toilet, a platform, or a dangerous place for visually impaired persons. Danger, and ventilation. The linear block is used to guide the visually impaired in the access road connected to the main entrance of the facility and is installed continuously in parallel with the guidance direction.

The Braille block specifies the installation standards in the Act on the Promotion of Convenience of Elderly Persons with Disabilities, etc. However, the contractor who does not know the meaning of the Braille block is installed differently from the meaning, or the Braille block is damaged or damaged, It is often difficult to understand the meaning clearly, so it is often difficult to walk.

In addition to braille blocks, various auxiliary devices such as obstacle access alarm, companion warning device, unidirectional or one-way information transmission system for the visually impaired have been developed for the visually impaired. However, There are great difficulties for people with disabilities to live their daily lives without feeling insecure.

Accordingly, there is a need to provide a guidance system that transmits the peripheral information of the visually impaired person more precisely and in real time than the conventional guide apparatus or system in order to provide the convenience of the visually impaired and extend the life range.
