23、煩——不必要的麻煩,這里有些心理學(xué)原理可以幫助我們設(shè)計出用戶看得懂而且又方便使用的產(chǎn)品。</p><p> 以門為例。我們在使用門時,無外乎兩種動作;開或關(guān)。假設(shè)你走在辦公樓內(nèi)的走廊上,然后一扇門前停下來,應(yīng)該從哪個方向開這扇門?是推是拉?從左邊是是從右邊?也許這是一個滑動拉門,如果真是這樣,應(yīng)該往哪個方向華東?我曾見過往上方開的門,令我頗感驚訝。使用門時,我們只會遇到兩個基本問題,門應(yīng)該朝哪個方向開,用戶應(yīng)該
24、往那邊用力。這些問題的答案應(yīng)該在門的設(shè)計上找到,而無需用文字或字符加以說明,更不應(yīng)該讓用戶在英國反復(fù)的實驗和出錯后再找到答案。</p><p> 一位朋友向我講述了他被困在歐洲某城市一家郵局的門道里出不來的情景。郵寄的入口很氣派,六扇雙開式的彈簧門排成一排,緊接著還有一排同種樣式的門。這是一種標(biāo)準(zhǔn)設(shè)計,目的是為了減少空氣的流通,從而保持樓內(nèi)的溫度恒定。</p><p> 我的這位朋友推
25、開了外邊靠左的那扇門,走進了大樓。在來到第二排玻璃門之前,他因為某事分心。轉(zhuǎn)了個身,當(dāng)時沒有意識到自己往右邊移動了一點。他來到第二排門前,用力一推,沒反應(yīng)?!耙欢ㄊ擎i上了?!彼南?,于是又去推旁邊那扇門,還是打不開。我的朋友一臉迷惑,決定沿原路返回,便轉(zhuǎn)身去推外面的那扇門,沒動靜。退旁邊的那一扇,仍舊沒反應(yīng)。他剛剛從這扇門走進來,還是打不開。他開始擔(dān)心起來,甚至有些驚慌——自己被困在門道里了!正在這時一群人從入口的另一邊(我朋友在右邊)
26、很輕松的通過了這兩道門,于是他趕緊跑過去,跟他們走進了郵局。</p><p> 怎么會發(fā)生這樣的事?</p><p> 雙開式彈簧門有兩邊,一邊又固定緩緩走和鉸鏈,另一邊可以自由開關(guān)。開門時,你必須推可以自由開關(guān)的那一邊,如果推有鉸鏈的那一邊,門就不可被打開。在上述情景中,設(shè)計人員只注意到了門的美觀,而未注意到門的易用性。結(jié)果是,用戶在使用這些門時看不到旋軸,一個普通的用戶正忙可能知道
27、從一邊開門?我的朋友在精力分散時,走到了有固定旋軸一邊,他用力推有鉸鏈的那一側(cè),難怪門紋絲不動。不過這些門卻相當(dāng)漂亮雅致,可能還榮獲過設(shè)計獎呢。</p><p> 以上例子說明了設(shè)計中的一項重要原則:客觀性。正確的草垛部位必須顯而易見;而且還要向用戶傳達出正確的信息。在設(shè)計那些用力推才能打開的門時,設(shè)計人員必須讓用戶一看見門,就知道往哪個部位推。應(yīng)該推的那一側(cè)貼上垂直金屬板,或?qū)⒐潭ㄐS顯露出來——這并不影響門
28、的美觀。垂直金屬板和固定旋軸屬于自然信號,可以被用戶直接感知到。我爸這種對自然信號的使用稱作自然設(shè)計,并還將在本書中詳細探討這一方法。</p><p> 可視性問題有多種表現(xiàn)形式。我的朋友唄困在兩排玻璃門之間,是應(yīng)為他看不到任何有關(guān)操作部位的線索。可視性問題的其他表現(xiàn)形式是關(guān)于用戶操作示意圖和可能的操作方法之間的匹配,這是本書將要討論的另一個話題。以某種類型的投影儀為例,這種投影儀僅靠一個按鈕來控制幻燈片槽的前
29、后運動。一個按鈕被賦予兩種功能?如何進行匹配?你怎樣才能知道控制幻燈片的方法?你不可能知道,應(yīng)為你在投影儀上看不到任何操作方法的提示。一下是我在某個不熟悉的地方講學(xué)時遇到一件事。</p><p> 我在各處講學(xué)的過程中,有好幾次看到萊茨牌的投影儀。首次使用時,發(fā)生了一起戲劇性的事故。那次是一名辦事認真的學(xué)生負責(zé)幫我放映幻燈片。當(dāng)我講完第一張幻燈片,需要用第二張幻燈片時,那名學(xué)生很細心地按下了控制鈕。只見幻燈片槽
30、開始往后移動,竟然滑出了投影儀,從桌上“嗶啦”一聲掉下來。槽內(nèi)的幻燈片灑落一地。學(xué)生大為驚愕,我也趕緊重新整理幻燈片,講座因此推出即了15分鐘。但這不是學(xué)生的過錯,而是這臺式樣雅致的投影儀的問題。只用一個按鈕來控制幻燈片的前后運動我們誰也搞不明白該如何操作。</p><p> 在講座的整個過程中,有需要幻燈片往前放,有時需要往后倒。后來,我們向當(dāng)?shù)氐募夹g(shù)人員求救。他解釋說,輕輕按一下控制鈕,幻燈片就會往前放;按
