碩士 === 國立高雄第一科技大學 === 電機工程研究所碩士班 === 105 === In our research, a portable reading device for the visually impaired is proposed it could replace the bulky traditional Braille books by electronic text document that is displayed on the mobile phone screen. First, there are some difficulties of developing of Braille display device will be point out, they including the way of Braille contact control, the resolution of the Braille contact, the drive of Braille contact device and so on. the implementation and performance of all Braille display device. Second, introduce the origin of Braille characters and the rules of Braille. They including the design of Android APP, the integration of optical sensing components, selection of the actuators and 3D modeling of Braille display device, and combined of put forward to reasonable method in Braille display device. Finally, the overall structure of the Braille display device is improved, and the accuracy of the optical sensing panel and Braille display device is tested.
