LINEAR PROTRUSION FOR GUIDING VISUALLY IMPAIRED PERSON
To solve problems in a linear protrusion for guiding a visually impaired person, when being stroked by a white stick by a user of the white stick, touch felt by the user is small, and much time is required for the user to know a longitudinal direction, and the user cannot be sure about the longitudinal direction and moreover, with a white stick to which a stick tip with different thickness is attached, contacting is not stabilized.SOLUTION: On a surface of a linear protrusion 3 for guiding a visually impaired person, there are provided protrusions 4 for forming corners 4c from a top face 4a to left and right side faces 4b.SELECTED DRAWING: Figure 1
【課題】視覚障害者誘導用の線状突起は、白杖の使用者によって、白杖でなでられても使用者の感触が薄く、使用者が、長手方向を知るには、時間がかかるとともに、確信を持てない不安がある。さらに、太さの違う杖先を付けた白杖では当たりが安定しない。【解決手段】視覚障害者誘導用の線状突起３の表面に、上面４ａから左右の側面４ｂにかけての角４ｃを形成する突起４が設けられている。【選択図】図１
