目前國內已有許多電腦輔具可以協助肢體障礙者操作電腦,但大多數都是針對某一種特殊需求而設計的,較適合輕度肢體障礙使用者,至於重度肢體障礙使用者,必須同時具備不同的輔具才能順利地操作電腦。本研究旨在發展一整合式替代性鍵盤,利用8051單晶片微電腦來控制觸控式螢幕以達成輸入和顯示的功能,主要提供一個簡單且方便操作的介面來做英文、注音和倉頡等輸入法與作業系統常用之快速鍵的切換及輸入。此鍵盤的輸入方式包含觸控、掃描和摩斯碼三種,讓不同需求的肢體障礙使用者可以選擇適合自己的輸入方式。另外,針對無法順利使用組合鍵的使用者,相黏鍵和常用快速功能鍵的功能可以幫助他們完成複雜的輸入動作。期望重度肢體障礙者在使用電腦時,透過這個整合式鍵盤能夠輕鬆順利地完成資料輸入。
Presently there are many computer assistive products developed to assist persons with physical disabilities in operating a computer. However, most of them are designed based on some special requirements, which are suitable for persons with lightly physical disabilities. For persons with heavily physical disabilities, different assistive products are needed at the same time because they usually have multiple physical disabilities. The objective of this research is to develop an integrated alternative keyboard, which serves as a friendly interface between a computer and people with heavily physical disabilities. With this keyboard, they can easily operate and type words with a computer. An 8051 single chip microprocessor is used to control a touch panel, which is responsible for receiving inputs from the user and displaying information. There are three operating modes in using this keyboard, i.e., touch, scan, and Morse code. Persons with different requirements can choose a suitable mode. For persons, who cannot use combination keys, the hot keys and stick keys in this keyboard help them complete the complex actions.
