Visual-cognitive loads influence the effectiveness of word prediction technology. Adjusting parameters of word prediction programs can lessen visual-cognitive loads. This study evaluated the benefits of WordQ word prediction software for users' performance when the prediction window was moved to a personal digital assistant (PDA) device placed at the keyboard level. Twenty-one young people aged 11-14 (11 new users and 10 experienced users) participated in the study. The Canadian Occupational Performance Measure was used to measure users' self-ratings of performance and satisfaction. Results of two-tailed paired t-tests reveal significantly (p < .05) higher performance and satisfaction ratings when the word prediction list was displayed on the PDA. Users reported that it was easier to look for the words at the keyboard level and to select words directly from the PDA. Visual comparisons of the users' typing speed and accuracy show that experienced users had faster typing rates and new users appeared to have better accuracy when they typed with WordQon the PDA display. Further studies with larger samples of individuals with different diagnoses and ages are required to confirm the benefit of using a PDA display in enhancing typing rate and accuracy.
