現今行動資訊產品已成為人們生活的一部分，其中平板電腦有著一般筆記型電腦沒有的手寫板功能，但是要將一台重量相當於筆記型電腦的產品，拿持於手上相當費力且不能持久，減少平板電腦的機件數量及大小，勢必可以減少使用者拿持時的負擔，因此將平板電腦外觀設計為純平板式之型態，而鍵盤輸入的部分，採用和弦鍵盤以及觸控筆按紐取代原有的QWERTY鍵盤，以達到減少重量之功效。

　　和弦鍵盤與平板電腦的整合為本研究重點，和弦鍵盤位於平板電腦上的位置，必須符合目前平板電腦使用者，拿持操作時的正確姿勢，包含手腕與手指之正確位置，以及操作和弦鍵盤之範圍，另外和弦鍵盤的編碼方式，以單手操作，用左手拿持平板電腦與操作和弦鍵盤，並測試各種適當編碼方式，何種編碼有較佳的輸入速度與較少的錯誤率，以供日後平板電腦設計之參考。

　　本研究之具體結論為如下所述，最佳拿持方式為左手四指位於右側，拇指位於上側。根據拿持方式來定義出手指操作範圍，男女之操作範圍有明顯差異，因此以女性之操作範圍，來定義和弦鍵盤按鈕之位置。四指要往上與往下伸展，是很難達成的，也就是四指方向為向左右移動，是可行的方式。但基於拿持的穩定度，以及避免受測者輸入時錯亂，定義拇指位置為空白鍵。四指個別的移動範圍較小，所以放置1~2個按鈕。使用Half QWERTY、BAT結合觸控筆，以及十鍵編碼為實驗之和弦編碼，測試輸入的速率以及錯誤率，輸入方式使用位於平板電腦上之和弦鍵盤，觸控筆上之按鈕，以及平板電腦視窗中之虛擬按鍵，測試得知按鍵數少之編碼，有最佳的輸入效率；使用觸控筆上的按鈕，比使用視窗中之虛擬按鈕，輸入速率要來的快。

　The mobile technological products have already become a part of people's life now. Among them Tablet PC is the products coming out in development in recent years. There is handwritten board function which general notebook computers do not have. But be equivalent to a weight the products of the notebook computer. Quite on hand take and hold strenuously and can't last. Reduce the quantity of parts and size of Tablet PC. Can reduce users and take the burden while holding. So design the exterior of Tablet PC slating to reduce a lot of weight. Adopt the chord keyboard to replace already existing QWERTY keyboard to key in. In order to reach the efficiency which reduces weight.

　The merger of the chord keyboard and Tablet PC is this research focal point. The position where the chord keyboard lies on the Tablet PC, must accord with the Tablet PC user at present. Take and hold the correct posture while operating, include the correct positions of the wrist and finger, and operate the range of chord keyboards. The way of the chord keyboard code, operate with one hand in addition. Take the Tablet PC and operate the keyboard of chords with the left hand. And test various kinds of proper code ways. Which code is better input speed and less wrong rates. For the reference which design the Tablet PC in the future.

　The concrete conclusion of this research, for stated the following. Four fingers for left hand that lie in the right side to take the way of opposing bestly, the thumb lies in upside. Define the fingers range of operating according to bringing the way of opposing. Men and women's operation range has obvious differences. So with women's operation range, come to define the position of chord keyboards button. Four fingers, with spread down up, is very difficult to reach. It is a feasible way that four fingers direction to that is to say for to move from side to side. On the basis of take stability degree when hold, it prevents from to be in disorder when inputting person who examine. It is a blank key to define the thumb position. Four fingers the specific movement range is relatively small, so put 1~2 buttons. It is chord codes of the experiment to use Half QWERTY, BAT with touch pen and ten key codes. Test the speed of introduction and wrong rate. The way of inputting which use the chord keyboard that lies on the Tablet PC, and the button of the touch pen. And the fictitious button of Tablet PC Windows. The button counts few chordcode have best inputing efficiency through testing. The inputting speed of using the button of the touch pen is faster than the ones that used the fictitious button of Tablet PC Windows.
