Comparison of performance measures between DS and DSLM in terms of (A) Accuracy, (B) Task Completion Time, (C) Bit Rate and (D) Theoretical Bit Rate. The accuracy is the percentage of the 36 characters that the participant correctly spelled. The maximum possible completion time, including pauses between character selection times, was 14 minutes, 47.5 seconds due to a sequence limit of 10. Bit rate is a communication rate that takes into account accuracy, task completion time and the number of possible character choices. Theoretical bit rate excludes the 3.5-second pauses between character selections.
