摘要

全球正面臨人口老化，對高齡使用者來說，生理與認知機能的老化，將導致資訊生活衝擊與不便。本研究試圖提升高齡者，在使用便利商店「多媒體資訊站」介面使用體驗。第一階段，歸納整理影響高齡者操作介面的因素，結果得到「按鈕形式」、「介面複合有無」、「資訊分類」及「時間分類方式」四個主要變項；第二階段將四個變項以單因子實驗設計方法分別帶入介面A 與介面B，進一步了解高齡者對介面使用性、主觀滿意度與心智負荷的影響。其結果顯示：1. 2D 與3D「按鈕形式」對使用性來說沒有顯著的差異；2.精簡介面資訊說明有助於理解介面內容；3.具有網路使用經驗，可讓介面操作花費更少的時間、心智負荷相對也較少，但介面操作的主觀滿意度上並無影響。

The whole world is subject to population aging, which, for the elderly, means the aging of their physiological functions. Such a trend will bring impact and inconvenience to people's utilization of information technologies. In this study, attempts have been made to improve the elderly's experience in using the ＂multimedia information station＂ interface of the convenience stores. In the first stage, factors that affect the elderly's interface operation are summarized and classified, namely the ＂button pattern＂, ＂composite interface＂, ＂information classification＂ and ＂temporal classification＂; in the second stage, the above four variables are put into Interface A and Interface B by design methods for a single factor test one by one, in order to further understand the impact of four factors on the elderly's interface usage, subjective satisfaction and mental load. The results turn out to be: 1. there is no obvious difference in the interface usage between 2D and 3D ＂button patterns＂; 2. simplifying the introduction to the interface will help the elderly understand the information about the interface; 3. the possession of network operation experience will help the elderly save the time spent on interface operation, and lower their mental load but has no impact on the subjective satisfaction concerning the interface operation.
