Finite State Machine

A computational model that can exist in exactly one of a finite number of states at any given time, transitioning between states in response to specific inputs or events. In assistive technology, finite state machines are used to translate simple binary inputs (such as muscle contractions or switch activations) into complex device control by defining how each input changes the current state and what action that state produces. This approach allows users with minimal input capability to control devices like wheelchairs, computers, or communication aids through sequences of simple actions.
