The slate is usually made from two panels that stabilizes the paper and while the stylus is used to punch through the holes in one of the panels to create the Braille dots. They include:-īraille slate and stylus: This is a low cost, portable low-technique writing tool. There are varieties of assistive technologies available that support for writing tasks. People with blindness face a lot of challenges in writing tasks involving typical writing or visual writing. Placing the opening of the cutout on the line assists someone to know exactly where they should sign. A signature guide is a credit card size piece of plastic that has a rectangular cutout in the bottom third of it. Typoscope/ Signature guide: It can be used for either reading guide (one window) or writing guide (multiple windows) according to the design being made. audio output as well as keystrokes entered on the keyboard, and navigational information. Screen Readers Software: This software allows people or students with low vision and blind to convert text on a computer screen and in documents to synthetic speech i.e. Digital Accessible Information System –DAISY, Book Port Plus etc. It enables students to read or access information through hearing e.g. MS Word, PDF, HTML etc.Īudio Format Materials (AFM): AFM is beneficial for many students with low vision and blind. BTS recognizes a variety of digital text files formats e.g. Refreshable Braille Display (RBD): Refreshable Braille Display works with a screen reader and enables the user to read what’s on the computer screen by touch on Braille display.īraille Translator Software (BTS): Braille Translation Software translates electronic documents into Braille codes and sends it to a Braille embosser (special Braille printer- Braille embosser) which produces a hard copy of the original text. Learning Braille reading with fingers is one of the oldest techniques to route for literacy among the blind people.

Learners with visual impairments face unique challenges in the educational environment. Based on International Standard Organization (ISO), the World Health Organization defines Assistive Technology as “any piece of equipment, product, or tool, whether it is acquired commercially, modified, or customized, that is used to increase, maintain, or improve the functional capabilities of individuals with disabilities”. “Assistive Technology” refers to a range of tools, devices, and strategies that allow a student to accomplish a task that they would otherwise be unable to do, or would have difficulty accomplishing effectively.
