隨著科技的發展，手機的功能更是日新月異，並朝著「行動電腦」的趨勢前進，而文字的輸入，將不再僅只於發送簡訊，像是收發信件、文書處理等都需要依賴文字輸入，但為了追求寬大的螢幕，手機按鍵卻朝向迷你化發展，也帶給了許多使用者在操作上的不便。

　　本研究透過產品設計程序，將滾輪運用於手機文字輸入裝置中，並和現有手機進行輸入比較，實驗結果證實應用滾輪於手機文字輸入裝置能增進輸入速率且學習時間短，使用者也給予相當的肯定。
　
　　研究提出兩款新式手機輸入裝置，分別使用二向及四向滾輪，而實驗分成兩個階段，且輸入裝置比較分為二向滾輪、四向滾輪以及模擬現有手機輸入的裝置共三種。在實驗階段一中，使用者必須在不知如何操作的情況下，依直覺進行輸入；實驗階段二則是在了解操作方式後，經過練習，在進行輸入測試，最後填寫問卷。

　　實驗階段一結果發現，二向滾輪在輸入速率有顯著優於模擬手機的表現。以平均來說，二向及四向滾輪都優於模擬手機。

　　而實驗階段二結果雖然三種手機間的輸入效率無顯著差異，但以平均來說，二向及四向滾輪都優於模擬手機。而問卷方面，績效與滿意度的部分，二向和四向滾輪也都有顯著優於模擬手機的表現。

As technology develops; the functions of mobile phones advances accordingly. It moves in the direction of “Mobile Computing”. The input of texts is not restricted to the input of short instant messages. Word processing relies on text input as well. However, the trend of bigger display screens moves in the trend of smaller buttons which causes many inconveniences on the operation of the user.

　　This study using scroll wheel into the text input system through product design process. This is compared to existing input system and the experiment shows that the usage of scroll wheels does shorten the input time and receives positive feedbacks from the users.
　
　　This study proposes two types of new input system namely two-way and four-way scroll wheels. The experiment consists of two stages and there are three input systems which are the two-way and four-way scroll wheel and an emulation of the existing input system. In the first experiment, the user does not learn the usage of the device and proceeds intuitively. In the second experiment, the users learn how to use the devices and after practice, input texts and fills in a questionnaire at the end.

　　In the first experiment, the input speed of two-way scroll wheel performed better than the emulation of existing mobile phones with the significant differences.

　　In the second experiment, there are no significant differences on the input rate between the three devices. However, on average, two-way and four-way scroll wheel performed better than the emulation of existing mobile phones. In the questionnaire, concerning satisfaction on the devices, two-way and four-way scroll wheel also showed significant improvement than the emulation of existing mobile phones.
