PROBLEM TO BE SOLVED: To provide a floor system for guidance of a visually impaired person in which mainly the guidance of the visually impaired person using a white stick is possible mainly in a building, and walking and passage are easy even for a healthy person and a wheelchair user.SOLUTION: A floor system for guidance of a visually impaired person is provided for guiding the visually impaired person by laying a visually impaired person guidance area 1 capable of being distinguished by the visually impaired person from other area 2 on a floor surface to thereby constitute a guidance path. The guidance path has a visually impaired person warning area 3 formed of a warning pattern in a branching point. The warning pattern comprises recesses and protrusions in which mutual height difference is less than 3 mm and height difference to the surface of the other area 2 of the visually impaired person guidance area 1 is less than 3 mm. Any one of these recesses and protrusions forms a reticulated pattern, and the other forms a dot-like pattern.SELECTED DRAWING: Figure 1
