| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 98 === There are many inconveniences with the disabled in the daily life, especially for quadriplegics. They almost have to be helped with everything by others and their lives are quite boring. As the reasons, we developed an assistive computer input device to help the disabled control a keyboard and a mouse by a nipple switch with Morse code encoding. In addition, an appliance control system was developed to help the disabled control appliances by themselves including TV, AC,…, and so on. However, before the disabled operate the computer, the assistive computer input device still has to be placed into the mouth of the user by others. Therefore, we propose an automatic transportation system to place/take the nipple into/from the mouth to make the disabled use the whole system more convenient without others’ help.
The hardware was constructed from mechanical supports, servo motors and gears. The software was programmed by LabVIEW. The system can learn and update the pattern data of user’s face to make the nipple switch put into the user’s mouth correctly.
The experiment in the factory, the average accuracy is 100%, the recognition similar rate is 96.5%, and the average time of transporting the nipple switch to the mouth is 96 seconds. For case study, the average accuracy is reduced because of environment differentness. After adjusting each parameter, the average accuracy is about 75%. The proposed system is a practical system, which can help the disabled operate the entire system more convenient. But the feasibility and the usability of the system still can be improved in the future research, especially the size of system.
