的相片檢視程式的觸碰式工具
這是什麼
顯示只回應觸碰或壓下按鍵動作的工具，並把工具放在內容上方、位於一個小而動
態的圖層裡。
何時使用
當你設計一種能讓人沉迷其中的全螢幕體驗時，例如影片、相片、遊戲、地圖或書
籍等等。為了管理體驗，使用者有時需要一些控制元件 — 導覽工具、媒體播放工
具、內容資訊……等等。工具需要擺在受到注意的位置，但又只是有時需要出現。
為何使用
大多數時間裡內容主宰使用者的體驗。使用者不會因為元件佔用內容的空間與專注
性就分心。請記得在行動裝置的環境中，空間與專注性甚至比平常更顯得珍貴。
使用者可藉由選擇工具呈現的時機來掌控體驗。

原理作法
用全螢幕顯示未經裝飾的內容。當使用者觸碰裝置的螢幕，或按下某個特定按鍵或
軟體鍵時，則顯示相關工具。
許多工具程式只在使用者觸碰螢幕的某個特殊區域時顯示觸碰式工具。如此一來，
使用者才不會在平常操作裝置時意外叫出工具。還有，可在觸碰螢幕的不同區域時
叫出不同的工具 — Stanza 電子書程式就是如此，請見圖 10-9 的範例。
請以小而半 透明、看似 浮在內容層 之上的
