01.Direct Manipulation and representation
如何減少界面的直接操作“障礙”磷瘤，以下是衡量界面是否好用的一些指標(biāo)：
可見度 visibility：perceived affordances or signifiers
可反饋 Feedback
一致性 Consistency ：also known as standards
無“毀滅式”操作 Non-destructive operations ：hence the importance of undo
可“發(fā)現(xiàn)” Discoverability: All operations can be discovered by systematic exploration of menus
穩(wěn)定性: Operations should work. Period. And events should not happen randomly.
通過界面幫助用戶建立認(rèn)知：
Encourage experimentation (如：俄羅斯方塊的例子岩灭，游戲中玩家有一大段空間和時(shí)間做比照，確認(rèn)后再把方塊放下)
Scaffold learning and reduce errors (如：重新定義抽象的概念，將抽象的數(shù)字游戲變成具象的棋盤游戲)
Show (only) differences that matter (如：倫敦地鐵圖)
Convert slow calculation into fast perception (如：分層設(shè)色地圖)
Support chunking, especially by experts?
Increase efficiency (圖表)
Facilitate collaboration?
02.Visual Design and Information Design
在英文字體中有x-height的概念，如：
hight x-height在分辨率低的適合更容易閱讀
low x-height給人優(yōu)雅的視覺感受
網(wǎng)格設(shè)計(jì)起源于包豪斯風(fēng)格涩蜘，最早接觸到這個(gè)概念是關(guān)于包豪斯的建筑理念，沒想到跟web設(shè)計(jì)這么有淵源
使用對(duì)話式的導(dǎo)航設(shè)計(jì)熏纯，如使用小子號(hào)副標(biāo)題來告訴用戶這個(gè)導(dǎo)航按鈕會(huì)帶你去哪里
