全球60 歲以上老年人口每年以約百分之二的速度成長，網路的發達、便利和普及，許多高齡族群也漸漸開始接觸這些網路科技通訊產品，加上會使用網路通訊的族群漸漸老化，可以預見未來高齡族群使用網路的人數將會明顯的逐年成長。但一般的網站設計師往往只重視主流使用者，而忽略了高齡族群在使用網路上的不方便，沒有考慮他們在瀏覽網頁上的困難。因此本研究特別考慮高齡者視覺、認知的退化來進行手機版網站設計的探討，我們針對國外以高齡者為目標族群之知名網站作視覺與認知的特徵值統計，選取特徵建議值，再配合高齡長輩之網頁評比結果，最後整理出有關網頁視覺與認知特徵之修改建議值，此結果可作為網站設計師在設計手機版網頁時之參考，以幫助網站設計人員製作出較體貼高齡使用者的網站視覺與認知效果，讓高齡族群有一個友善的網站瀏覽經歷。

The number of persons aged 60 or over in the world grows by two percent every year. Many elders use smartphones owing to the popularity of the Internet and their number can be expected to increase quickly in the near future. However, most mobile website designers plan their websites for younger mainstream users and do not incorporate ease-of-use elements for older users. This paper aims to provide design guidelines for mobile website designers that take into consideration older users’ vision impairment and cognitive ability, both of which decline with age. We gathered the statistics of feature values from 100 well-known foreign senior sites, invited several elders with smartphone usage experience to evaluate the recommended feature values, and finally obtained the design guidelines regarding visual and cognitive features for mobile websites. These guidelines can help designers create more elder-friendly websites.
