第六章
何時使用
用在設計一個具有高度互動性的 UI，其中的行為比簡單的導覽或表單的填寫複雜
許多的時候。這類的軟體包含郵件閱讀程式、資料庫軟體、寫作工具、繪圖軟體，
以及程式開發工具。
為何使用
復原一長串 操作的能力 ，讓使用者 覺得可以放 心地探究此 介面。他們 一面學習介
面的用法，一面動手做實驗，知道不管做任何事都可以取消 — 甚至意外做出「不
好」的事，也可以取消。支援此模式的軟體，不只對於初學者有幫助，對於任何程
度的使用者都有幫助
*
。
一旦使用者熟悉介面，他就有自信知道犯錯不會是永久的。如果誤選了錯誤的選單
項目，不需要繁複的手續就可以復原；使用者不需要先回復到之前存檔的舊檔案，
關閉介面然後重新開始，也不需向系統管理員請求回復備份檔。這個模式可以讓使
用者省下許多時間，免除偶然操作失誤後的精神壓力。
多 層 復 原 也 讓 專 家 級 的 使 用 者 很 快 且 很 容 易
