Condition of little or no useful sight and little or no useful hearing

Deafblindness is the condition of little or no useful hearing and little or no useful sight. Different degrees of vision loss and auditory loss occur within each individual. Because of this inherent diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual modality deprivation, to improve their ability to live independently. In 1994, an estimated 35,000–40,000 United States residents were medically deafblind. Helen Keller was a well known example of a deafblind individual. To further her lifelong mission to help the deafblind community to expand its horizons and gain opportunities, the Helen Keller National Center for Deaf Blind Youths and Adults (also called the Helen Keller National Center or HKNC), with a residential training program in Sands Point, New York, was established in 1967 by an act of Congress. The deafblind community has its own culture, comparable to those of the deaf community. Members of the deafblind community have diverse backgrounds but are united by similar experiences and a shared, homogeneous understanding of what it means to be deafblind. Some deafblind individuals view their condition as a part of their identity.

Braille equipment includes a variety of multipurpose devices, which enhance access to distance communication. Some can be used as stand alone devices connected via Wi Fi, while others are paired with a mobile device to provide tactile access to e mail, text messaging, and other modern communication resources. To receive Braille equipment, an eligible consumer must be proficient in Braille and must have access to the Internet or cellular telephone service. Telebraille does not have a computer communications modem, but does have a TTY (TDD) modem. It was designed as a TTY for deaf blind people and is also useful for face to face conversation. It has two components: The sighted component is a modified SuperCom TTY device. It has a qwerty keyboard and a single line LED display. The display is regular size and is not particularly suited to people with low vision. The SuperCom TTY can be connected directly to the telephone line using a conventional telephone jack or the telephone receiver can be coupled to the SuperCom on a cradle on top of the device. Text flows past the display in a continuous stream, like tickertape. The SuperCom is connected to the Braille portion of the device by a cable that is about 2 ft (0.6 m) long. The Braille display is about 15 characters in width, although a knockout allows additional characters to be installed, at considerable additional cost. The Telebraille is able to communicate in ASCII mode, but is not compatible with conventional computer modems. There is what looks like a RS 232 socket on the back of the Braille component, but the instructions for the Telebraille state that this jack is for "future use" and that no computer devices should be attached to it. A graphic Braille display can be used in sensing graphic data such as maps, images, and text data that require multiline display capabilities such spreadsheets and equations. Graphic braille displays available in the market are DV 2 (from KGS), Hyperbraille, and TACTISPLAY Table/Walk (from Tactisplay Corp.). For example, TACTISPLAY Table can show 120*100 resolution refreshable braille graphics on one page.

The play The Miracle Worker (1959), which was adapted into the film The Miracle Worker (1962), recounts Anne Sullivan's efforts to draw Helen Keller from her world of blindness and deafness. The Who’s album Tommy (1969) tells one continuous life story about a deafblind mute boy named Tommy through songs. The Bollywood film Black (2005) featured Rani Mukerji as a deafblind character named Michelle McNally. The film Marie's Story (2014) relates the childhood and education of Marie Heurtin (1885–1921), a deafblind woman. Haben Girma, the first deafblind individual to graduate from Harvard Law School, released an autobiography entitled Haben: The Deafblind Woman Who Conquered Harvard Law (2019). Feeling Through (2019) is an American short drama film directed by Doug Roland that was the first film ever to star a deafblind actor (Robert Tarango) in a lead role; it is about a teenager and a deafblind man. It was nominated for the 2021 Academy Award for Best Live Action Short Film. The Persistence of Vision is a 1978 novella by John Varley describing the life of a blind and deaf community.
