In recent years, due to rapid developments in information technology, modern technologies have begun to rapidly enter human life. These technological advances are creating wide opportunities for everyone (regardless of physical and mental capabilities). Due to these opportunities, people with disabilities also had the opportunity to learn to read and write. People with disabilities who are blind use Braille to learn and communicate in their daily lives. In this age of modern technological advances, it is hard to imagine our daily life without digital devices such as tablets, smartphones, laptops, and computers. Computers play a vital role in the education process of visually impaired people. Computers have a specially designed external USB Braille keyboard that helps blind people with educational processes. This paper proposes a low-cost folding type Braille keyboard. This device is beneficial through its innovative design and its simplicity.
