A switch is required to interface with ACAT. Finding the right switch to work for your needs can make a big difference.
Assistive Context-Aware Toolkit (ACAT) enables users to easily communicate with others through keyboard simulation, word prediction and speech synthesis. Users can perform a range of tasks such as editing, managing documents, navigating the Web and accessing emails.
