Mobile Phone Application for Supporting Persons with Higher Brain Dysfunctions
This paper shows a mobile phone application for supporting persons with higher brain dysfunction (HBD) such as a cognitive disorder, a memory disorder, and an attention-deficit disorder. This application serves them as a schedule manager, an alarm and an instructor of work sequences. The development concept of this application is easy handling and simple display, because persons with HBD are easily bewildered by complex procedures in the work. Five persons with HBD participated in the experiments for assessing the application at the vocational training place. The use of the application resulted in the drastic decrease of the number of errors and the increase of the System Usability Score, indicating that the developed application is useful for persons with HBD especially in performing vocational training tasks such as the use of database software on PC.
