Braille is a tactile writing system used by the blind and the visually impaired, and found in books, on menus, signs, elevator buttons, and currency. Braille characters are small rectangular blocks called cells that contain tiny palpable bumps called raised dots. The number and arrangement of these dots distinguish one character from another (source: Wikipedia).

A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of raising dots through holes in a flat surface. Blind computer users, who cannot use a normal computer monitor, use it to read text output. Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances (source: Wikipedia).

In the modern digital age, the advent of the "refreshable braille display" toolbox reflects a new age marketability of user-friendly handicap-target technologies. These technologies culturally compel populist educational institutions such as Dartmouth College (Hanover, New Hampshire) and CalTech (California, USA), to offer symbolic handicap-friendly braille-analagous "signposts" such as braille-only version library college mission statements for investors and students alike to celebrate.

These new clinic trend considerations psychologically reflect the civilization value of relevant education-populism Hollywood (USA) movies such as "Educating Rita" (1983).

Are they printing movie posters on hemp/recycled paper yet?

God bless!
