An IoT based smart stick for blind and visually impaired person

Abstract

Vision loss has a devastating effect on the lives of those who experience it. It affects as well as on their family, friends and society. Completely loosing or deterioration of eyesight is frightening and unbearable which leaves those affected to question their ability to maintain their independence, remain employed, and provide for themselves and their families. Loss of vision can affect one’s standard of life, his independence and mobility as well as it also has been linked to falling down, being injured, mental health issue, social function, cognition and educational attainment. In our society visually impaired or blind people is not very uncommon. At least 2.2 billion people have a near or distance vision impairment globally according to the World Health Organization (WHO). People with vision impairment have lower rates of productiv ity and workforce participation. They also have high rates of anxiety and depression. The deterioration of vision that they have to suffer from not only matter but also the overall quality of their lives deteriorates too. Vision impairment causes social isolation, a higher risk of falls and fractures. The biggest challenge for a blind per son is to navigate around places. Without a human guide he or she cannot navigate around places, especially in a new terrain. Vision impairment is associated with an increased risk of fractures which has been shown in multiple studies. This prob lem can be life threatening as well.To make life easier for someone with vision loss, SMART STICK has been developed. By detecting obstacles and identify the cur rent position of the blind and visually impaired person IoT based SMART STICK can solve many challenges. Basic requirements of the blind and visually impaired person can be met through this Stick. This IoT based Smart Stick can make a visually impaired person to walk more confidently. The study hypothesizes with the concept of a Smart Stick which allows a visually impaired person to navigate over obstacles and have less incidents.The development work of this Stick involves coding and physical installation of various types of components. The aim of this project is to build a smart stick that could communicate with its users helps him to move freely and overcome his disability.
