The United States began to develop rehabilitative approaches; these became established among practitioners by the 1960s, including the introduction of the long cane and the Perkins brailler: the lessons learned from adult rehabilitation were then applied to CYPVN in the 1980s forming the beginnings of habilitation practice, although at this stage, it was still strongly grounded in rehabilitative perspectives (e.g. dressing skills for children in the seminal work, in the United States, of Klein, 1995; more recently in Australia: Johnston, Flavel and Lunn, 2002).

Braille & Barbier in 1829 introduced the slate and stylus for visually impaired students to write, which has the similar mechanism like pen and paper for sighted people (Cheadle, 1994). Blind people in Bangladesh write by using slate and stylus; and read by sensing the embossment of raised dot with fingers. Through the braille method, users emboss braille characters on a paper of substantial thickness by using slate and stylus or Perkins Brailler. However, in Bangladesh, blind students can only use slate and stylus due to the unavailability of Perkins Brailler.
