Introduction[edit | edit source]

The term Assistive Technology is generic term used to describe assistive, adaptive and rehabilitative devices for people with varying degrees of disability. They are aimed at assisting or expanding human function or capabilities. Assistive Technologies can be complex and range from sophisticated computerized communication systems and software programs to a simple handle on a telephone. [1] Recent studies show that up to 1% of the world population suffers a degree of speech, language or communication need. [2] There are communication devices, also called Augmentative and Alternative Communication (AAC) devices, that are equipment people use to communicate without using verbal speech.[3] The lives of people with communication difficulties can greatly be boosted by the Augmentative and Alternative Communication ( AAC) systems by promoting independence, social relationships and education. [4]According to WHO, more than 1 billion people globally need 1 or more assistive products but only 1 in 10 people in need have access to assistive products. [5]

Who might need a communication device?[edit | edit source]

Children and adults with complex communication needs require the use of an AAC in their daily lives either as a permanent solution or a temporary one after surgery. The assistive communication products may be particularly helpful for people living with conditions such:

Types of Communication Products[edit | edit source]

  • Augmentative and alternative communication (AAC) devices help people with communication disorders to express themselves. These devices can range from a simple picture board to a computer program that synthesizes speech from text. The ACC can either be low-tech :*Low-tech AAC is any type of aid that does not require batteries or electricity. They may include simple pen and paper to write messages on, pictures boards, that can be carried to aid communication by can pointing on to images, words, pictures, drawings, or letters. High-tech AAC - Any aid that requires electricity or batteries. They might include specialized devices, software, smartphone applications, electronic communication boards, and keyboards. Most of high -tech AAC devices are Speech Generating Devices and can produce digitized speech when the user either types a message or presses on images, words, or letters.
  • 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. Several types of ALDs are available to improve sound transmission for people with hearing loss and are some are designed for large facilities such as classrooms, theaters, places of worship, and airports, while others are intended for personal use in small settings and for one-on-one conversations. All can be used with or without hearing aids or a cochlear implant. ALD systems for large facilities include hearing loop systems, frequency-modulated (FM) systems, and infrared systems.
  • Infrared systems use infrared light to transmit sound. A transmitter converts sound into a light signal and beams it to a receiver that is worn by a listener. The receiver decodes the infrared signal back to sound. As with FM systems, people whose hearing aids or cochlear implants have a telecoil may also wear a neckloop or silhouette inductor to convert the infrared signal into a magnetic signal, which can be picked up through their telecoil.
  • Unaided communication systems use body language to communicate. They include gestures, body language, and/or sign language.
  • Electronic Fluency Devices help improve people with stutters to become more fluent.

.

Where to use Assistive Communication Products?[edit | edit source]

They can be used:

  • In a classroom
  • At home
  • At work
  • On the go


Benefits of Assistive Technology Communication Products

There are several benefits in using the communication products:

  1. They help people with communication disorders to express themselves.
  2. They increase self esteem and confidence of their users.
  3. They enable people to live their lives fully without being excluded in the society.
