Abstract

Numerous health problems, particularly those involving the eyes, are associated with advancing age. It is difficult to live a normal life when you're blind. Visually impaired people face navigational difficulties both inside and outside of an environment, particularly those who are blind because of ageing. Numerous tools are available in the outdoor environment, such as pavement paths and kerbs. These, on the other hand, are ceramic, concrete, or metallic in nature, and once installed, their alignment cannot be altered. As a result, there is a need for adhesive-based tactile that is easily replaceable to meet the needs of the occupants of the house. The purpose of this paper is to design and develop various types of tactile using Thermoplastic Polyurethane (TPU) material and a 3D printer. These tiles include a Warning tile, a Straight tile, a Turning tile, and a Junction tile with surface indicators; elderly people can easily navigate their homes with the help of these tiles.
