第一章
許多使用者在使用系統一陣子之後，就會養成一些奇怪的習慣，足夠滿意正是導致
此結果的原因。很久以前，使用者可能學習使用 A 路徑來完成一件事，後來新版本
雖然提供了 B 路徑，這是更好的替代方式（或是 B 路徑一直存在），但是使用者
卻不想學 B 路徑 — 學習畢竟要花時間 — 所以繼續使用比較沒有效率的路徑 A。
這並非沒有理性的選擇，因為打破舊習慣，學習新東西需要花力氣，對於使用者來
說，為了一點點小改進而學習可能還不夠划算。
中途改變（
Changes in Midstream
）
『對於我剛剛做的事，我改變主意了』
偶爾，人們會在事情做一半的時候，改變主意。可能原本走進房間是為了要找一把
鑰匙，但是還沒找到，卻先看到報紙而讀起報紙來了。或者到 Amazon 的網站上看
書評，最後卻買下一本書。或許我們只是做到一半，分心開始做別的事了；或許是
刻意做此改變。不管怎樣，使用者使用你所設計的介面時，他的目的改變了。
對於設計師來說，這意味著應該提供改變心意的機會。提供其他選擇，不要讓使用
者陷入缺乏選擇、無法連結到其他網頁或功能的環境，千萬不要這樣，除非你有很
好的理由。這類理由的確存在。請見第二章精靈模式（Wizard）與第三章情境面板
模式（Modal Panel）的範例。
你也可以為使用者簡化以下步驟：啟動一個程序、半路停止、稍後回來、繼續之前
的進度 — 這常常被稱為「re-entrance」（再度進入）。比方說，一名律師可能拿
著 iPad，正在表單上輸入資訊。然
