Laws of UX 2.0

Laws of UX is a collection of psychological and behavioral design principles that helps designers understand users' perception, cognition, and behavioral responses when interacting with interfaces. It serves not only as a reference framework for design decisions but also as a systematic tool for user experience thinking.

The content covers classic psychological laws: such as Hick's Law (more options lead to slower decisions), Fitts's Law (larger or closer targets are easier to click), and Jakob's Law (users expect your site to work like other sites they commonly use); user attention and memory mechanisms: such as the Zeigarnik Effect (unfinished tasks are more memorable) and the Von Restorff Effect (distinctive items are more memorable); cognitive load and behavioral motivation theories: such as the Peak-End Rule (users better remember the peak and end of an experience); visual and interaction design guidance: such as consistency principles and progressive disclosure strategies.

By studying Laws of UX, designers can: understand the psychological mechanisms behind user behavior to make more scientific design decisions; optimize interface structure and interaction details to reduce user operational burden; enhance interface usability and appeal to increase user satisfaction and retention; establish theoretical foundations for user experience design and transform experience into reusable knowledge.

使用者體驗法則集合了眾多基於心理學與行為學的設計原則，幫助設計師理解使用者在使用介面時的感知、認知與行為反應。它不僅是設計決策的參考框架，更是一套系統的使用者體驗思維工具。

內容涵蓋。經典心理學法則：如希克定律（選項越多，決策越慢）、費茨定律（目標越大或越近，越容易點選）、雅各布法則（使用者期望你的網站像其他常用網站那樣工作）等；使用者注意力與記憶機制：如齊加尼克效應（未完成任務更容易記住）、馮·雷斯托夫效應（突出的專案更容易被記住）；認知負荷與行為動機理論：如峰終法則（使用者更容易記住體驗的高潮與結束部分）；視覺與互動設計指導：如一致性原則、漸進披露策略等。

透過學習 Laws of UX，設計師能夠：理解使用者行為背後的心理機制，做出更科學的設計判斷；最佳化介面結構與互動細節，減少使用者操作負擔；提升介面的易用性與吸引力，增強使用者滿意度與留存率；建立使用者體驗設計的理論基礎，將經驗轉化為可複用的知識。
