摘要

資訊化社會的來臨使電腦呈現普及化的趨勢。一般大眾所接受並使用的輸入設備為 QWERTY 鍵盤與滑鼠，但目前這兩者為分開的輸入設備，因此在人因上、操作上、攜帶上產生了問題。和弦鍵盤的發展無論是在國外或是國內皆證實可以解決人因工程上的問題，且在輸入績效上並不比 QWERTY 鍵盤差，但都未將滑鼠的設計一併考慮在內。
本研究人因工程和弦鍵鼠結合了和弦鍵盤與滑鼠之優勢。經過人體計測、績效探討與學習曲線測量實驗後，顯示出人因工程和弦鍵鼠在輸入績效方面，最多需要 358.5 分鐘，最少 126.4 分鐘可達到個人標準鍵盤的英文輸入績效。點選實驗方面，人因工程和弦鍵鼠已經能夠達到一般市售光學滑鼠 81.7% 之績效。滑鼠編輯實驗，經過績效探討與學習曲線實驗後，績效已經超越一般市售光學滑鼠。人因工程操作姿勢實驗方面：左手尺偏角度為 17.35°，背屈角度為 4.9°；右手尺偏角度為 12.4°，背屈角度為 1.75°，皆低於標準鍵盤 20°。
在經過一連串的練習與實驗後，顯示人因工程和弦鍵鼠之績效均可達到慣用輸入設備之績效，甚至有更好的表現，且能減少腕部屈曲和偏向的角度，並可增加使用空間與靈活度。本研究之結果可供未來鍵盤與滑鼠設計者參考，以設計出更健康與適用之鍵盤、滑鼠與和弦鍵鼠。

In the information era, the use of the computer has become extensive than ever. Input devices used by the general public are QWERTY keyboard and mouse. The fact that these 2 devices are separated results in ergonomic, operational and portability issues. It has been proven locally and internationally that the chord keyboard can effectively solve ergonomic issues while its input efficiency is not inferior to that of the QWERTY keyboard. None, however, has incorporated the design of the mouse.
The ergonomic chord keyboard-mouse of this study integrates the strength of the chord keyboard and mouse. Ergonomic test, performance evaluation and learning curve measurement indicate that, in terms of input efficiency, it takes 126.4-358.5 minutes to attain the English input efficiency of the standard keyboard. Regard click test, the ergonomic chord keyboard-mouse has been able to attain 81.7% of the efficiency of ordinary optical mousse sold in the market. In the area of mouse editing experiment, through performance evaluation and learning curve experiment it has surpassed ordinary optical mouse sold in the market. Dynamic anthropometry reveals: Ulnar deviation angle of the left hand is 17.35°, dorsal flexion angle of the left hand is 4.9°, ulnar deviation angle of the right hand is 12.4°, and dorsal flexion angle of the right hand is 1.75° – all below the 20° of the standard keyboard.
Following a series of practices and experiments, it has been demonstrated that the ergonomics chord keyboard-mouse can attain the efficiency of familiar input devices, or even higher efficiency. Wrist flexion and deviation can be alleviated; the use space and flexibility can be enhanced. Findings of this study can serve as keyboard/mouse design references to help designers create more healthful and suitable keyboard, mouse and chord keyboard-mouse.
