For the purposes of these Principles:

a)  The term persons with disabilities includes those who have long-term physical, mental, intellectual or sensory impairments which in interaction with various barriers may hinder their full and effective participation in society on an equal basis with others;

b)  Right to freedom of expression refers to the right to freedom of expression and information which includes the freedom to seek, receive and impart information and ideas of all kinds, regardless of frontiers, orally, in print, in the form of art, through print, broadcast or digital media or through any other media of his or her choice;

c)  Accessibility means a precondition for persons with disabilities to live independently and to participate fully and equally in society. It encompasses a duty to ensure access to the physical environment, and to all facilities and services which are open and provided to the public, including to information and communication services, and digital communications technologies and systems;

d)  The term adaptive technology refers to any object or system that is specifically designed for the purpose of increasing or maintaining the capabilities of persons with disabilities, in particular access to digital technologies;

e)  The term assistive technology refers to assistive, adaptive and rehabilitative devices for persons with disabilities that enable them to independently perform tasks that they would be otherwise unable to accomplish, or would have great difficulty accomplishing, including but not limited to Braille translation programmes, CCTV, video or screen magnifiers or enlargers, screen readers, closed captioning and subtitling, audio description, keyboard emulation, on-screen keyboards, light signaller alerts, reading tools and learning disabilities programs, screen or voice recognition tools, text-to-speech or speech synthesizers and others;

f)  The term communication include languages, display of text, Braille, tactile communication, large print, accessible multimedia as well as written, audio, plain- language, human-reader and augmentative and alternative modes, means and formats of communication, including accessible information and communication technology;

g)  Discrimination means any distinction, exclusion or restriction on the basis of disability which has the purpose or effect of impairing or nullifying the recognition, enjoyment or exercise, on an equal basis with others, of all human rights and fundamental freedoms in the political, economic, social, cultural, civil or any other field. It includes all forms of discrimination, including denial of reasonable accommodation;

h)  The term reasonable accommodation refers to necessary and appropriate modifications and adjustments not imposing a disproportionate or undue burden, where needed in a particular case, to ensure persons with disabilities the enjoyment or exercise on an equal basis with others of all human rights and fundamental freedoms. Reasonable accommodation should be made to include and support persons with disabilities as long as the adjustments are reasonably possible to do, and are within the financial and technological capabilities of those doing the adjustments;

i) The term universal design refers to the design of products, environments, programmes and services to be usable by all people, to the greatest extent possible, without the need for adaptation or specialised design. It should not exclude assistive devices for particular groups of persons with disabilities where this is needed.
