| Summary: | 碩士 === 國立臺灣師範大學 === 資訊工程研究所 === 97 === With the development of computer technology, computer is becoming an essential part in our life. But, to operate on computer might be a very difficult task for persons with physical disabilities. At present, there are many on-screen keyboard software been developed to assist persons with physical disabilities. However, these software can not fulfill the complex demands of the on-screen keyboard for people with physical disabilities.
The purpose of this study is to develop an adaptive on-screen keyboard system which can include a on-screen keyboard evaluation process. Using the on-screen keyboard evaluation process, users will get his personal proper settings of the on-screen keyboard, including: the input mode of the on-screen keyboard, the size of the on-screen keyboard, the size of keys on the on-screen keyboard, and the minimum delay time in hovering mode. In addition, we also design a XML format of the user evaluation report, and create a user-adaptive adjustment on-screen keyboard to satisfy the needs of different users.
Our system provides not only shortcuts function but also menu operating function which is better than most of the current on-screen keyboard software. User can quickly and easily control the start menu, pull-down menu and popup menu to reduce the burden of the people with physical disabilities. In other words, it can simplify or speed up the computer operation. In addition, it can also flexibly adjust the settings and layout of the on-screen keyboard according to user's different demand. This research can help people with physical disabilities to use computer and input data in more convenient and easier way.
