Accept symbol-based input
For some users with cognitive disabilities or who are learning a new language, it is much easier to understand concepts that are displayed in images rather than text. An on-screen communication aid can allow input by clicking on images rather than letters. For example, the user may ask when dinner is by clicking on a “clock” image followed by a “food” image. This input can then be converted to text or read aloud by the computer.
Discussion by Disabilities
Cognitive, Language, Learning Disabilities & Low Literacy
Using symbols instead of text can greatly simplify input for people with cognitive, language, and learning disabilities and those with literacy problems.
