摘要

近年來，迷你筆記型電腦不斷推層出新，在而追求越輕越小的當下，卻因螢幕尺寸及鍵盤配置的限制，造成使用上的不方便。本研究探討迷你筆記型電腦之螢幕尺寸（7吋－11.6吋）與輸入裝置配置之操作績效影響。本研究探討操作四種尺寸迷你筆記型電腦內建輸入裝置與螢幕(7吋/8.9吋/10.1吋/11.6吋)與五種操作任務種類(多向目標點擊、多向目標觸碰、連續點選、連續觸碰、和打字)之關係。研究中以Visual Basic 撰寫計測程式進行模擬測試實驗(操作時間和錯誤率)和主觀評量。
實驗結果以單因子變異數和事後檢定進行分析。實驗結果顯示，(1)在工作任務一至四(多向目標點擊、多向目標觸碰、連續點選、連續觸碰)中， 8.9吋的操作績效與10.1吋/11.6吋在統計顯示是均無顯著差異，而7吋的操作績效上均不佳。(2)在工作任務五(打字輸入)中， 8.9吋的操作績效與10.1吋/11.6吋在統計顯示是均有顯著差異，而7吋的操作績效上也不佳。在主觀實驗結果顯示，(1)大部分的受測者對於11.6吋的迷你筆記型電腦內建輸入裝置上有較高的評價。(2)受測者對於7吋的迷你筆記型電腦內建輸入裝置評價很低。研究結果所獲得輸入裝置與操作任務之關係，可提供相關廠商建議，並為未來在生活3C產品輸入裝置介面設計參考。

In recent years, netbooks have always come up with new designs, and while everyone wants lighter and smaller, the screen and keyboard are constrained by the size and became user-unfriendly. This study explored the impact of the size of the screen and keyboard of netbooks (7”-11.6”) on operating performance. This study explored the relationships between built-in input devices and screens (7”, 8.9”, 10.1” and 11.6”) of 4 different sizes of netbooks, and five types of operational tasks (multi-directional click, multi point touch, continuous selection, continuous touch and typing). The study was carried out by a test program written in visual basic to simulate the test environment (in terms of operating time and error rate), and also a subjective evaluation.

The test result was analyzed through one-way ANOVA and post hoc tests. The result showed that: (1) For operational tasks 1-4 (multi-directional click, multi point touch, continuous selection and continuous touch, there was no significant differences on operating performance between 8.9” and 10.1”/11.6” screens. The operating performance of the 7” screen was not good. (2) For operational task 5 (input by typing), there were significant differences on operating performance between 8.9” and 10.1”/11.6” screens. The operating performance of the 7” screen was again not good. From a subjective evaluation, the result showed that (1) Most of the subjects gave higher value to the 11.6” netbook with a built-in input device. (2) The subjects gave very low value on the built-in input device of the 7” netbook. The relationships between the input device and the operational tasks obtained from the study can provide suggestions to related manufacturers and serve as a design reference for input devices on 3C products in the future.
