Abstract

Last 20 years, billions of people around the world are widely using digital devices. In this information technology age, it is difficult to imagine our life without digital devices including computers. Computers play an important role in the lives of visually impaired people. These devices help them with electronic tasks such as writing mailing messages, and word processing tasks. Computers based on modern technologies for blind people are available worldwide. Computers have a specially designed external USB Braille keyboard with large six dots that help blind people type SMS messages easily and quickly. This paper proposes a low-cost external USB Braille keyboard for computers which is designed to help blind and visually impaired people type quick messages. This device is beneficial through its innovative concept, its simplicity, and its availability at an affordable cost.
