Introduction

An Assistive Device is any device that helps persons with disabilities or Impairments to do something that they might not otherwise be able to do well, or at all, thus giving that person more independents. Assistive Devices or Assistive Technology can help persons who are Deaf or have Hearing Impairments to communicate if they have a speech, or language disorder are equipment like Hearing aids, Assistive listening devices (ADL), Argumentative and Alternative Communication (AAC) devices & Alerting Devices. With the development of digital and wireless technologies, more and more devices are becoming available to help people with hearing, voice, speech, and language disorders communicate more meaningfully and participate more fully in their daily lives. Assistive devices can help a person with day-to-day activities like Alerting devices on a door bell, so that a door bell blinks a light instead of a noise to indicate someone is at the door. Health professionals use a variety of names to describe assistive devices:

  • Assistive listening devices (ALDs) help amplify the sounds you want to hear, especially where there’s a lot of background noise. ALDs can be used with a hearing aid or cochlear implant to help a wearer hear certain sounds better.
  • Augmentative and alternative communication (AAC) devices help people with communication disorders to express themselves. These terms often refer to devices that help a person to hear and understand what is being said more clearly or to express thoughts more easily.These devices can range from a simple picture board to a computer program that synthesizes speech from text.
  • Alerting devices connect to a doorbell, telephone, or alarm that emits a loud sound or blinking light to let someone with hearing loss know that an event is taking place.

Hearing Aids

Hearing aids are devices used by partially deaf individual to regain a portion of hearing by amplifying sound. They work to improve the hearing and speech comprehension of those with hearing loss. It works by magnifying the sound vibrations in the ear so that one can understand what is being said around them. The use of this technological device may or may not have an effect on one's sociability. Some people feel as if they cannot live without one because they say it is the only thing that keeps them engaged with the public. Others dislike hearing aids very much because they feel wearing them is embarrassing or weird. Due to their low-esteem, they avoid hearing aid usage altogether and would rather remain quiet and to themselves in a social environment.

Hearing Dogs & Equipment

A Hearing Dog is a Service Animal for persons who are Deaf or Hearing Impaired. Service animals are defined as animals that are individually trained to do work or perform tasks for persons with disabilities, they are working animals and not pets, so the work or task that the animal has been trained to provide must be directly related to the person's disability. Animals whose sole function is to provide comfort or emotional support do not qualify as service animals. There are various types of Service Animals used in countries around the world, including Guide Horses in the UK and Service Monkeys in USA, but these are currently not trained or used in South Africa. Hearing Dogs and training is available from various organizations in South Africa for persons who are Deaf or Hearing Impaired, while training of various other types of Service Dogs is also available to assist Persons With Disabilities, such as:

Instant messaging software

Instant messaging (IM) is a type of online chat which offers real-time text transmission over the Internet. It is sometimes used by deaf people to communicate online. A LAN messenger operates in a similar way over a local area network. Short messages are typically transmitted between two parties, when each user chooses to complete a thought and select "send". Some IM applications can use push technology to provide real-time text, which transmits messages character by character, as they are composed. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat.

Sign Language

Sign language is a language which chiefly uses manual communication to convey meaning, as opposed to acoustically conveyed sound patterns. This can involve simultaneously combining hand shapes, orientation and movement of the hands, arms or body, and facial expressions to express a speaker's thoughts. Sign languages share many similarities with spoken languages, which depend primarily on sound, which is why linguists consider both to be natural languages. There are however some significant differences between signed and spoken languages, such as how they use space grammatically, sign languages show the same linguistic properties and use the same language faculty as do spoken languages. They should not be confused with body language, which is a kind of non-linguistic communication.

Wherever communities of deaf people exist, sign languages have developed, and are at the cores of local deaf cultures. Although signing is used primarily by the deaf, it is also used by other people who can hear, but cannot physically speak.

It is not clear how many sign languages there are. Aside from the pidgin International Sign, each country generally has its own, native sign language, and some have more than one (although there are also substantial similarities among all sign languages). The 2013 edition of Ethnologue lists 137 sign languages. Some sign languages have obtained some form of legal recognition, like in South Africa, while others have no status at all.

In linguistic terms, sign languages are as rich and complex as any spoken language, despite the common misconception that they are not "real languages". Professional linguists have studied many sign languages and found that they exhibit the fundamental properties that exist in all languages. Today, linguists study sign languages as true languages, part of the field of linguistics.

A common misconception is that sign languages are somehow dependent on spoken languages: that they are spoken language expressed in signs, or that they were invented by hearing people. Sign languages, like all natural languages, are developed by the people who use them, in this case, deaf people, who may have little or no knowledge of any spoken language.

As a sign language develops, it sometimes borrows elements from spoken languages, just as all languages borrow from other languages that they are in contact with.

Telecommunications relay service technologies

There are several new telecommunications relay service technologies including IP Relay and captioned telephone technologies. A deaf or hard of hearing person can communicate over the phone with a hearing person via a human translator. Phone captioning is a service in which a hearing person's speech is captioned by a third party, enabling a deaf or hard of hearing person to conduct a conversation with a hearing person over the phone. Wireless, Internet and mobile phone/SMS text messaging are beginning to take over the role of the TDD.
