這是什麼
在配備觸控螢幕的裝置上，於按鈕、連結，和任何可點擊的元件周圍設置較大的邊
緣與留白。
何時使用
需要使用加上文字標籤的按鈕、或需列出一份項目清單、或需使用文字連結時 —
簡而言之，任何不夠大的觸控目標物。
為何使用
觸控目標必須夠大，我們的粗手指才能成功地點擊。尤其是目標物要夠粗，這對於
只由文字組成的按鈕和連結會是個問題。
原理作法
每個觸控目標都加上內邊界、邊框與外圍的留白空間，做成可供指尖點擊的大目標。
有一項技巧 ，直接用留 白圍繞住可 點擊的目標 。按鈕的尺 寸看起來還 是一樣，因
此能符合視 覺設計的要 求，但我們 從按鈕周圍 的空間中多 得到幾個可 以感應的像
素。Dan Saffer 在《Designing Gestural Interfaces》中稱呼類似元件為「iceberg
tips」（冰山一角）— 它們都比肉眼所見的部分還大。
至於目標要多大，這是個非常好的問題。理想中，我們想要的尺寸，在實體裝置中
要大
