UI交互设计是设计人与UI之间的“对话”，交互设计的目的包括对UI的有用性、易用性和吸引性方面进行设计和改善。近年来，随着互联网的发展，特别是进入数字时代，多媒体的应用让交互设计的研究显得更加多元化。产品的功能越来越复杂，提高产品用户体验的需求越来越迫切，这些对交互设计提出了越来越高的要求。 本书从研究交互设计与用户体验的关系开始，图文并茂、循序渐进地讲解了UI交互设计的基础、UI设计规范、交互设计的UI布局、UI中各种元素的交互设计方法和技巧，并且向读者介绍了交互动效设计的相关知识，通过对交互动效案例的讲解，使读者能够轻松掌握交互动效的制作方法和技巧，全面提升读者的UI交互设计水平，达到学以致用的目的。

本书共分为6章，由浅入深地对UI交互设计知识进行讲解，帮助读者在了解UI交互设计知识的同时将这些知识合理运用于实际的UI设计中，帮助读者完成从基本概念的理解到实际操作方法与技巧的掌握。
第1章 UI交互设计基础。本章主要向读者介绍有关UI设计、UI交互设计的基础知识，包括交互设计与用户体验的关系、交互设计的基本流程，以及进行交互设计的过程中各关键步骤的分析等内容，使读者对交互设计有全面的认识和理解。
第2章 UI设计规范。本章全面细致地向读者介绍iOS和Android系统的UI设计规范，通过对设计规范的学习，使读者在针对不同系统的UI进行设计时更加得心应手，设计出更规范的移动端UI。
第3章 交互设计的UI布局。本章主要向读者介绍UI布局、格式塔原理等相关内容，有效提升UI的可用性，并且对UI的交互设计表现方式及特点进行介绍。
第4章 界面元素的交互设计。本章向读者介绍UI交互设计的细节与表现方式，使读者能够理解并掌握UI中不同元素的交互表现形式，从而有效地提升UI的交互体验。
第5章 UI交互动效基础。本章向读者介绍有关UI交互动效的基础知识，使读者能够深入理解交互动效，并向读者介绍制作UI交互动效的相关软件和基础表现方法。
第6章 UI交互动效设计与实现。本章向读者介绍UI中各种元素交互动效的表现形式和方法，并通过案例使读者掌
UI交互动效的制作方法。
