Word Prediction

A text input feature that suggests complete words based on the characters already typed, using language models to anticipate the most likely intended word. In assistive technology, word prediction is particularly valuable for single-switch users and people with motor impairments, as it significantly reduces the number of keystrokes or switch activations needed to compose text. Effective word prediction can increase text entry rates by 50% or more in scanning-based systems, though the cognitive load of monitoring prediction lists can offset some speed gains for certain users.
