A model of performance cost versus benefit for augmentative communication systems

Many augmentative and altemative communication (AAC) systems provide a benefit of keysavings at the c a t of increased cognitive-perceptual requirements. A user performance model is derived that shows how cost and benefit determine text generation rate in these systems. The accuracy of the model is evaluated, and examples of useful applications are presented.
