Rate, Accuracy, and Efficiency of Text Entry as a Function of Different Computer Access Methods
By Hubbard, Sandra L., MA, OTR; Spaeth, Donald M., PhD; RESNA 26th International Annual Conference 2003,Publication Date: 2003
Study conducted to investigate the use of a computer data-logging program designed to quantify the accuracy and efficiency of individualized alternative computer access interventions for three participants with moderate to severe motor impairments. The intervention would allow the therapist and consumer to determine whether some alternative individualized computer access interventions are more efficient than a standard keyboard and mouse. In the baseline phase of the study, participants entered text with a standard keyboard and mouse. In the second phase, participants entered text using one of three computer access modifications: (1) Minspeak voice recognition software, (2) Pathfinder communication aid, and (3) HeadMaster pointing device. A “Text-Timer” program was written to measure the characters per minute entered by each of the three participants. The application was found to effectively measure the performance and descriptive text input data of people using alternative methods of computer access.
