Title:
WALKING GUIDE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/169050
Kind Code:
A1
Abstract:
The present invention relates to a walking guide system and, particularly, to a walking guide system providing walking guide information on the basis of afterglow of a Raman-shifting material and the swinging direction of a walking guide apparatus. The present invention may provide more accurate walking guide information by means of a sensor for sensing the swinging of the walking guide apparatus and the Raman-shifting material. The present invention may provide walking guide information by painting smart paint, that is, a walking guide pattern on pre-installed braille blocks, thereby substantially aiding a visually impaired person to walk by oneself. Further, since a walking guide pattern can be applied by simply painting in a place which does not have braille blocks, the present invention greatly reduces construction cost and construction time compared to braille blocks, and greatly increases effects. Since the Raman-shifting material in a paint form can be applied by simply painting, the present invention may reduce installation cost and maintenance and repair cost compared to braille blocks.
