All data for this follow-up evaluation were collected through one-on-one telephone discussions with beta test subjects. The discussions followed a topic list which was used as a guide - not as a questionnaire. These topics are presented below under "Results." Nine of the beta test participants provided input to this evaluation. The two subjects who did not provide typing data as part of the beta test were not approached, and one of the subjects could not be reached in the time available. The cooperation of all participants was excellent. There was clear and obvious enthusiasm for PBCAT.
