摘要

高齡者是資訊市場中較為弱勢的一群，在目前電腦輸入設備中以滑鼠為最普遍使用的設備，本研究的課題在如何讓高齡者能更容易的使用滑鼠來操作電腦。本文共進行三部份研究，包含「滑鼠操作困擾度研究」、「介面適用性研究」以及「介面調整模式研究」。在滑鼠操作困擾度研究中，針對20位高齡受測者以問卷訪談的方式了解高齡者經常使用電腦的目的，以及滑鼠操作的困擾點。其以ANOVA分析的結果發現，高齡者經常使用電腦從事上網查資訊、收發電子郵件和瀏覽部落格的動作，而高齡者對於滑鼠的困擾點常發生在滑鼠尺寸、游標的大小和游標移動速度。因此在「介面適用性研究」中，24位高齡受測者對27種不同滑鼠尺寸、游標大小及游標速度組合的滑鼠介面，進行不完全平衡之滑鼠適用性實驗，並以ANOVA檢測，結果發現，在滑鼠尺寸方面：小型滑鼠的績效最差；游標大小方面：小游標的錯誤次數大於中游標以及大游標；游標速度方面：慢速游標的任務時間大於中速游標和快速游標，而快速游標的錯誤次數大於中速游標。「介面調整模式研究」中，發現以點選的方式並且有資訊回饋最受到高齡者喜愛。本研究的結果可作為逐漸高齡化的社會中，針對電腦輸入設備做因應設計的參考。

The amount of computer users is highly arised not only at the young people but alos the elderly people. But the usability of input device for elderly users is still less concerned than for the young users by the computer suppliers. This paper focused on the usability of the interface of computer mouse for elderly users, in which three parts of studies were preceded. Firstly, a questionnaire survey to 20 elderly computer users showed that the larger bother on the input device at their usage were the mouse size, the cursor size, and the control of cursor speed. And the one mean t-test also found that the more frequently objects on the computer usage were information searching on web site, email logging, and blog browing. Secondly, an uncomplete balanced experiment was conducted that 24 elderly users tested 27 randomly assigned mouse devices which were combinations of those three largly bothered factors. The ANOVA test showed that the smallest mouse had the largest mean error-clicking (MEC) frequency; also the smallest cursor had the larger MEC than default and larger cursors; the fast cursor had the larger MEC than default and slow cursors. Finally, three designs of adaptive interface for on-line adjustment of cursor size and speed were proposed to those users; and the ANOVA test showed that the click-and-feedback design was the most preferred adaptive interface after a complete balanced experiment. The results suggested that the adjustment of cursor at the size and speed should be clear verified at the screen with one simple mouse click for the elderly computer user.
