Here a writing, Braille and drawing board for the blind or visually impaired is described. In one implementation, a slate is provided that can be used by a person to write any languages (such as but not limited to English, Hindi, Tamil, Malayalam, German, French or for that matter any languages) and to perform mathematical calculations. The slate solves the problems of writing and performing mathematical operations in a single device which uses the same technique which visually impaired people have learnt for writing in an affordable and user friendly package. The slate includes two plates, a stencil and a stylus. The bottom plate has raised dots and the stylus tip has depression which gives helps in embossing the texts. A single column stencil covering just one line helps in exposing other part of the page which can be read without taking out the paper.
