空間記憶（
Spatial Memory
）
『我發誓剛剛那個按鈕還在那裡，現在怎麼不見了？』
當人們處理物件和文件時，他們常常會記得在哪裡找到它們，而不記得它們的名字。
以 Wi n d o w s 、Mac、Linux 桌面為例，許多人在 桌 面上放置文件、常用程式等東
西。其實，人們傾向使用空間記憶、在桌面上尋找東西，而且這是相當有效率的方
式。例如說，人們會有自己的分類方式，或是會記得『這份文件位在右上角、某個
東西和某個東西附近』。（當然，現實生活中也有相同的事。許多人的辦公桌都是
「有組織的混亂」，雖然混亂，但是辦公桌的主人有辦法立刻找到東西。要是別人
幫他整理桌面……老天請保祐他。）
許多應用程式會把它們的對話框按鈕（確定、取消……等等）放在可預期的地方，
部分的原因正是空間記憶的影響很強大。在複雜的應用程式中，人們也會透過位置
的關連來找東西：工具列的工具、階層中的物件……等。因此，我們應該小心地使
用反應式內容揭露（Responsive Disclosure，第四章）這類的模式。在介面的空白
處加上某些東西，通常不會造成問題；但是重新安排既有的控制元件，有可能會干
擾空間記憶，讓東西變得不容易找到。總之要視情況而定。如果你不確定的話，讓
你的使用者試試。
伴隨著習慣性（這與空間記憶有密切關聯），跨平台與平台上各個應用程式如能具
有一致性會是件好事，空間記憶則是為何要有一致性的另一個理由。因為人們或許
會期待在相近的位置找到相似的功能。範例請見登入工具模式（Sign-in Too
