Abstract
Elderly and visually impaired people will have low vision due to aging problem, disease, or accident. These people encounter difficulties in conducting an independent life, which is intrinsic to the nature of their impairment. Navigation in the known/unknown environment seems difficult without external help. There is a need of self-explanatory tactile indicators sensing through their foot and navigate in a home environment. The home environment layouts are dynamic in nature as furniture and other items’ position will be changed frequently. In this paper, we designed and developed an adhesive tactile walking surface indicators (ATWSI) and tactiles to navigate in the home environment with the help of a 3D printer technology using acrylonitrile butadiene styrene (ABS) and thermoplastic polyurethane (TPU) material.
