Input modes: their importance in the clinical application of electronic aids for disabled persons.
In this study of techniques for the operation of environmental control aids for disabled persons, 12 programmed input modes were investigated in a uniform typing task. A microprocessor-based electronic aid (MECON) developed for this project was operated in 1 mode at a time by the disabled subject using a joystick and/or switch. Fourteen severely handicapped subjects with a wide variety of disabling conditions participated in the investigation. In the results, various input modes were ranked in order of speed. The fit and stability of the transducer were found to be important to the subjects' performance, and there were a number of indications that the availability of multiple input modes for an aid is highly desirable.
