An AAC user indicates a series of numbers on an eye gaze communication board in order to convey a word. Augmentative and alternative communication (AAC) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language.
Fixed display devices replicate the typical arrangement of low-tech AAC devices (low-tech is defined as those devices that do not need batteries, electricity or electronics), like communication boards. They share some of disadvantages; for example they are typically restricted to a limited number of symbols and hence messages. [37]
For example, a picture may be taken of a child’s room and included in the AAC system. Objects and events within the photograph can then be used as symbols for communication. The concept of play could be accessed by selecting the toy box, whereas selecting an individual toy could generate the name of the toy (e.g. blocks) (Drager, Light ...
[30] [31] AAC devices can be no-tech (sign language and body language), low-tech (picture boards, paper and pencils), or high-tech (tablets and speech generating devices). [29] The choice of AAC device is very important and should be determined on a case-by-case basis by speech therapists and assistive technology professionals.
Communication board: Low-tech AAC device that displays pictures or words to which an individual points to communicate; Communication disorder: Disorders in speech, language, hearing, or listening that create difficulties in effective communication; Disfluency: Interruptions in the flow of an individual's speech
Words Strategy is a Minspeak software program that uses a more advanced form of iconic encoding, designed for the adolescent or adult AAC user who is able to combine words into more complex sentence sequences using picture-grammar symbol sequences. [7] This application allows for the generation of more than 2,500 words using this sequencing format.
Low technology (low tech; adjective forms: low-technology, low-tech, lo-tech) is simple technology, as opposed to high technology. [1] In addition, low tech is related to the concept of mid-tech, that is a balance between low-tech and high-tech, which combines the efficiency and versatility of high tech with low tech's potential for autonomy ...
Picture communication symbols (PCS) are a set of colour and black & white drawings originally developed by Mayer-Johnson, LLC for use in augmentative and alternative communication (AAC) systems. These AAC systems may be high-tech, such as the TD Pilot, or low-tech such as a communication board. PCS symbols are now owned and maintained by Tobii ...
