'''Computer accessibility''' (also known as '''accessible computing''') refers to the [[accessibility]] of a [[computer system]] to all people, regardless of [[disability]] type or severity of impairment. The term ''accessibility'' is most often used in reference to specialized hardware or [[software]], or a combination of both, designed to enable the use of a computer by a person with a disability or impairment. Computer accessibility often has direct positive effects on people with disabilities.
Accessibility features are meant to make the use of technology less challenging for those with disabilities. Common accessibility features include [[Text to Speech|text-to-speech]], [[Closed captioning|closed-captioning]], and [[keyboard shortcut]]s. More specific technologies that need additional hardware may be referred to as [[assistive technology]].<ref>{{Cite journal|
There are many disabilities or impairments that can be a barrier to effective computer use. These impairments, which can be acquired from [[disease]], [[Major trauma|trauma]], or maybe [[Congenital disorder|congenital]], include but are not limited to:

=== Hearing impairment ===
While [[sound user interface]]s have a secondary role in common desktop computing, these interfaces are usually limited to using [[system sound]]s such as feedback. Some software producers take into account people who can't hear due to hearing impairments, [[silence]] requirements, or lack of sound-producing software. The system sounds like beeps can be substituted or supplemented with visual notifications and captioned text (akin to [[closed captioning]]). Closed captions are a very popular means of relaying information for the Deaf and hearing-impaired communities. Modern [[computer animation]] also allows for translation of content into sign language by means of sign language avatars, such as [[SiMAX]].<ref>{{cite web |url=http://sowartis.com/projects/simax/#1481043240786-c3380c92-a941 |title=SiMAX |author=<!--Not stated--> |date=2018 |website=Sowartis |access-date=22 September 2020}}</ref><ref>{{cite conference |url=https://dl.acm.org/doi/10.1145/2049536.2049557 |title=Assessing the deaf user perspective on sign language avatars |last1=Kipp |first1=Michael |last2=Nguyen |first2=Quan |last3=Heloir |first3=Alexis |last4=Matthes |first4=Silke |date=October 2011 |publisher=[[Association for Computing Machinery]] |book-title=Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS-11) |pages=107–114 |___location=Dundee, Scotland |doi=10.1145/2049536.2049557 |conference=13th ACM SIGACCESS Conference on Computers and Accessibility }}</ref>

==== Impacts in the classroom ====
When accessible technology allows personalized learning, there are positive impacts on students. Personalized learning switches the focus from what is being taught to what is being learned. This allows the students to need to become an integral part of the learning process. Accessibility in the classroom allows millions of students of all backgrounds to have equal educational opportunities and keep up with their non-disabled peers.<ref name=":0">{{Cite journal|
When PC's are personalized for students in the classroom, students are more comfortable in the classroom, special needs students are better assisted and teachers can save time and effort.<ref name=":1">{{Cite web|url=https://resources.finalsite.net/images/v1523977320/parklandsdorg/scxoldfn8ywuvxfok0aj/Accessibility-in-Education-Workshop-long-9-23-15.pdf|title=Accessibility in Education|date=2011|website=Microsoft}}</ref>

==== Impacts outside the classroom ====
Parents and teachers can notice the long term effects that accessibility has on students with disabilities. This can include enhanced social skills, better relationships with family and friends, increased understanding of the world around them, and an exhibition of self-reliance and confidence. Changes can not only be seen in children but adults as well. The use of social media can aid parents to gain knowledge, share knowledge, and receive moral support.<ref name=":2" /><ref>{{Cite journal|
