Table 2.

Number of sequences, number of characters selected per minute with the pause between characters (and without the pause between characters in parentheses), bit rate with the pause between characters (and without the pause between characters in parentheses), and average accuracy for the copy-spelling runs in Phase I of the study and for the copy-spelling runs that preceded the free-spelling runs of Phase II, for each of the four Phase II participants.
