摘要：When we ponder about technology for people with visual disabilities, two broad domains come to our mind: General technology and Assistive technology. General technology is inclusive of computers, smartphones and cell phones whereas Assistive technology consists of devices developed to help people with vision impairment or other visual disabilities. The Assistive technology comprises everything starting from screen readers for visually impaired people or screen enlargers for low vision PCs, to braille watches and braille printers. In most of the system, prototype has been developed which will ease the routine chores performed by the visually impaired individuals. We will provide most of their prototype details in this paper along with some other scenarios. There is some development in the specified field of reading printed as well as digital text. These technologies help visually impaired people to read normal text with the help of audio outputs. We will also focus our attention on those aspects which are still in development phase and are facing some critical problems. The primary motive of this technology is precise scanning and text-to-speech transformations in order to achieve efficient output.
