Single-Message AAC Device

A simple augmentative and alternative communication (AAC) device that records and plays back a single message when activated, typically via a large button or switch. Examples include the BIGmack Switch and similar products. These devices are often used as introductory AAC tools for individuals with significant cognitive or motor disabilities, allowing them to participate in communication with a single action. In HCI research, single-message devices provide a controlled way to study intentional communication in nonverbal subjects, as activation requires deliberate action and produces consistent, measurable output.
