中文摘要：

为了研究基于iOS系统的平板电脑电子阅读软件在人机交互方面的特点,采用专家评估法评测了4款现有阅读软件的可用性问题,之后在调研基础上总结出基于iOS系统平板电脑阅读软件在文章组织方式、文章呈现方式、页面切换方式、导航方式等方面的特点,并制作出3种电子阅读软件原型,最后通过可用性测试研究3种原型给用户阅读体验带来的差异.实验结果显示：多层级的组织结构不利于用户快速搜索文章;图标与操作手势较多的软件会带来较高的任务负荷.该研究对平板设备电子阅读器的交互设计的启示有：尽量减少层级结构,可选图标以及操作手势应尽量简单、一致.

英文摘要：

In order to research the characteristics of e-readers based on iOS-based tablet computers in the area of human-computer interaction,we evaluate and test four existing e-reading applicationson their usability issues.Then we conclude different features of organizing and presenting passages,turning pages and navigating of e-readers based on previous study.Then we make three e-reading prototypes on tablets,with which we conduct usability test to study the differences of reading experience they bring to users.The result shows that multi-level design may slow down users＇ searching speed.Besides,users are prone tohaving more workload if there are too many icons and gestures in the application.It can be inspired that designers should decrease the number of levels for tablet e-readers and the icons and gestures used in the software should be as simple and consistent as possible.
