電腦指標輸入整合器之設計與應用

Abstract

Despite the great number of computer input devices available commercially, many disabled persons still rely on special equipment to operate computers. Providing those persons with an adequate human-computer interface should improve their productivity and efficiency. However, the specialized equipment needed is usually expensive, difficult to obtain and difficult to maintain. This study developed an economical apparatus that, flexibly integrated commercial computer mice and trackballs to tailor them for individual needs. This led to improved individual performance and resolved the problems of cost and poor maintainability of special equipment. The apparatus conforms to and work on a standard USB 1.1 interface and is compatible with most tested computer input devices.Efficiency of this apparatus was evaluated by four high level spine injured patients (C4-6). They performed the normal move-and-click and drag-and-drop activities that carried out by computer pointing devices. All subjects, who were without the ability to use an ordinary commercial computer mice or trackball, were able to operate the computers adequately with the apparatus and achieved scores higher than 20% of the best performance of an able person with an ordinary pointing device. Three of the subjects, including one operating a trackball with his chin, were able to operate computers easily and smoothly. This study shows that this apparatus is capable of integrating commercial pointing devices flexibly to enhance computer operability for disabled persons.
