- Techniques for Increasing Text Entry Efficiency

Several techniques have been developed to increase text entry efficiency. These methods are similar in that they decrease the number of physical actions (e.g., keystrokes, switch activations) needed to generate text. Increasing text entry efficiency may increase text entry rate, but that is not guaranteed [1-4]. A frequent consequence of reducing the motor requirements associated with text entry is to increase the cognitive and perceptual load on the user, which can actually reduce text entry rate [5].
