Intellectual disabilities (IT) are defined as a significant limitation in an individual's life, and are characterized by substantially below-average intellectual functioning and deviations in two or more adaptive skills, such as self-care, communication, social skills, functional academic knowledge, free time, etc. .

Intellectual difficulties arise before the age of 18 and last a lifetime.

The cause of intellectual disabilities is not always known, but it is known that their appearance can be influenced by genetic and environmental factors. Also, IT often occurs together with some genetic syndromes such as Down syndrome.

People with intellectual disabilities differ in the amount and extent of support they need to function in their daily lives. Also, some people with intellectual disabilities may have associated difficulties in motor functioning or in language and speech development . With this in mind, assistive technology and devices for assisted communication can provide support in everyday life to people with intellectual disabilities .

People with intellectual disabilities can facilitate communication with simple communicators, such as QuickTalker or GoTalk , but also communication software such as Communicator 5 or Grid 3 . The mentioned software can be used with the help of switches or with the help of visual communication.
