替代性輸入裝置與個人助理之整合設計

Abstract

電腦輔具乃是為了幫助肢體障礙者方便操作電腦而設計的輔助工具，不過大多數的電腦輔具是針對單一需求設計，若需多種輸入功能，則須同時使用多種電腦輔具才能順利的操作電腦。本研究著重在發展一整合式的輸入裝置，利用8051單晶片配合液晶面板及觸控螢幕達成顯示和輸入功能，提供簡單的盤面切換介面來做英文、注音等輸入法及常用快速鍵的觸控輸入，同時也提供掃瞄及摩斯碼等輸入方式來完成鍵盤輸入動作。並且整合滑鼠功能，期望能讓肢體障礙者透過本系統來完成鍵盤及滑鼠的操作動作。 此外為增加系統的附加功能，本系統也整合了個人助理的設計，藉由觸控輸入的方式，讓不方便握筆記事的肢體障礙者有適合的記事工具。期望這樣的整合設計能為肢體障礙者帶來更多資訊生活上的便利。

Computer assistive products are developed to help people with physical disabilities in operating a computer. However, most of them are designed for a single function; more than one assistive product must be used at the same time for multiple input functions. This research focuses on the developing of an integrated input device. We use an 8051 microprocessor along with a liquid crystal display and a touch panel to display keyboard layout and let disabled users input data. Besides the touch input function, this system also provides scanning input and Morse code input for people with different needs. We also integrate the functions of a mouse in this device. Thus, handicapped users can carry out the works done by a keyboard and a mouse with this device. To increase its practical value, this system also includes the function of a personal digital assistant. Through the use of touch input, physically disabled users can keep notes without a pen or paper. We hope this integrated system can help make information technology more accessible to the disabled.
