• A comparison of Mouthstick and Morse code text inputs Levine S, Gauger J, Bowers L, Khan K. (1986) Augmentative and Alternative Communication, 2(2), 51-55. Show abstract Mouthstick and Morse code input methods were compared with respect to their effectiveness in transcriptive typing. Six able-bodied subjects without previous Morse code training were tested. Learning rates and final transcriptive typing rates obtained over a 2-month period were calculated for each method. The final average typing rates for mouthstick and Morse code input modes were 12.6 and 7.88 words per minute, respectively. Average mouthstick learning rates were also greater than Morse code learning rates. One quadriplegic patient who was a regular user of a Morse code computer interface was tested and had a 12.4 words per minute typing rate. These results indicate that the mouthstick input method surpassed the Morse code method in input rate and learning rate for the relatively short term of this study. However, prolonged testing should be done with disabled subjects to further explore the uses of both modes of input.
• Morse code typing training of an adolescent with cerebral palsy using microcomputer technology: case study Hsieh M, Luo C. (1999) AAC: Augmentative & Alternative Communication, 15(4), 216-221. Show abstract The automatic recognition of unstable Morse code allows users to type text in Morse code with varying speeds. However, without individualized training and consistent daily use, a person with physical impairments may find it difficult to obtain a high recognition rate when using automatic recognition devices. For this reason, an interactive training approach implemented on a single-chip microcomputer with immediate visual and auditory feedback is proposed in this study. The training system was applied to an adolescent with cerebral palsy to improve his Morse code typing rate, stability, and recognition rate via daily practice. After 4 months of training, results from this study show that the participant's performance increased over time.
