Alternative input devices

Definition

Alternative input devices are specialized hardware tools that allow users to interact with computers and digital systems in non-traditional ways. These devices cater to individuals with disabilities or specific needs by providing alternative methods of input that enhance accessibility and usability. They can include various technologies such as adaptive keyboards, eye-tracking systems, and speech recognition software that facilitate interaction for those who may struggle with standard input methods like a mouse or keyboard.
