ABSTRACT

Abstract One-Sixth of the world population is suffering from vision impairment, as per WHO’s report. In the past decades, many efforts have been done in developing several devices to provide support to visually blind and enhance the quality of their lives by making them capable. Many of those devices are either heavy or costly for general purposes. In this paper, a detailed comparative study of all the relevant devices developed for them has been presented which are wearable and handheld. The focus was on the prominent features of those devices and analysis has also been performed based on few factors like power consumption, weight, economic and user-friendliness. The idea was to build a path for the researchers who are trying to work in this field by either developing a portable device or through some efficient algorithm to ensure independence, mobility, and safety for visually impaired persons.
