A Survey on Various Techniques and Applications used for Helping Visually Impaired People in Daily Life

It is estimated that 16.6 percent of the world's population suffers from a certain degree of sight problems, as stated by the World Health Organization (WHO). In recent times, a considerable amount of work has been put into the production of a wide variety of different devices to support and help people who are visually challenged and to improve their living standards by providing them with more independence. The purpose of the present study is to better understand the variety of cutting-edge methods which were developed to be of assistance to people who are blind or visually impaired and are currently being used in the market. Users may access a range of algorithms of deep learning, numerous sensors, and text to speech and speech to text output options with these programs, which are useful for a number of platforms, including Apple devices as well as Android devices, and are free to download. The purpose of writing this study is to offer a succinct summary of current advancements in the techniques that are being used in this subject. It is crucial that precise information be provided to other researchers in this area of study who are striving to find new applications for their findings.
