一、实验目的
The goal of this exercise is to focus your critical thought on those features of a computer
system that promote usability or hinder it. To this end, you will be asked to write a short
essay discussing the usability shortcomings of an application of your choosing. Note that
many technically elegant and successful applications are suitable candidates for
scrutiny—since, sadly, technical virtue and usability are often not found together.
As you examine the application, think about usability issues in order to find specific reasons
why the application's interface fails in some respect, and then propose solutions to correct
this failing. As much as you are able, ground your reasons for both the failings and the
solutions on the principles of psychology you have just been introduced to. Also, propose a
way to test your solution—to see if it really addresses the problem, not merely your individual
taste. That is, you will need to propose an experiment that will demonstrate the effectiveness
of your solution for real users.
Please note that, to a considerable extent, the tools you need to carry out these tasks
successfully are covered in detail in sections of this course that you have yet to take. However,
this is not a problem: the purpose of this initial exploration of usability issues is to 1) give you
an opportunity to reflect on the importance of good human-centered design, 2) allow you to
practice thinking about the psychology of the users in a focused way, and 3) allow you to
apply this psychology reasoning to user interface design.
二、实验内容
1. Choose an application to observe. This can be a Web page, a standard application, a
utility program—even a gadget or appliance that has interesting user-interface
features.
2. Write an essay of no more than two pages in length. The essay should include:
o
A brief description of the system or application you are critiquing. If at all
possible, include a picture or drawing to help us understand this application.
o
A concise statement of the problem you have observed.
o
An explanation of why you believe this is a problem based on the content of
"1.1.3 Basic Psychology Needed for Interface Design." (Don't merely say that
a feature is "annoying" or "ugly," but explain how it forces a user to perform
2
the tasks of perceiving, processing, or acting in ways that are difficult for
people.)
o
A suggestion for improving the design and a rationale for that suggestion.
(When proposing a solution, try to be as realistic as possible and not suggest
costly or complicated enhancements. For example, it probably would not be
reasonable to propose that VCRs should recognize and process human
speech, as this would make them very expensive, if not unfeasible to build.)
o
A method for testing your new design to see if it actually solves the problem.
This part should include brief descriptions of
What you would measure about people's behavior as they use the
original application and your modified redesign.
The types of people you would use in your test (e.g., computer-savvy
experts or novices, etc.).
The tasks that you would ask those people to perform.
A prediction of the results you might get.
What those results would mean if you got them.
3. When you are finished, put your essay into a file (ask your teacher about admissible
formats, such as Word or plain text).
三、实验方法
了解用户界面设计的基本内容
四、实验步骤
1. 寻找一个设计较差的界面。
2. 对界面功能进行介绍。
3. 对界面进行批判。
五、实验结果
中南大学教务网络管理系统
在使用中南大学教务网络管理系统时，对此系统的界面设计有一些不满意之处，以下进行对此系统主界面的介绍和缺点的批评以及改进建议。

隐藏左侧选项栏
返回上一个界面
上方表格简述了该软件的主要功能模块，我对这个软件的功能还是比较认可的，它能充分的满足学生的基本要求，使学生对自己的学习进程有一个全面认知。
我对这个软件的批评之处在于其糟糕的界面设计，主要从以下几个方面进行批判：
1. 首先是页面的布局，这个主界面将一系列功能选项放在界面的左方，而中间的大部分区域是空白的，给人一种非常粗糙的感觉，使人的心里感到不舒服。
2. 两个意义不明且容易混淆的按钮，一个是向左方的箭头按钮，一个向上方的箭头按钮。大多数人的经验里向左方的的按钮一般是返回上一步，但这里的功能确是将左侧的选项栏隐藏，不符合人们的日常经验。而另一个向上的箭头则是返回上一步，刚使用此软件的人很难想到这个按键的功能。总之这两个按键对用户操作造成了很大的不便。
3. 这个软件的颜色搭配过于单调，只有绿白两种颜色，而大部分区域都是白色，尤其是隐藏左侧选项栏是，整个界面变成一片白色，给人一种很不好的心理感受
改进建议：
1. 就主界面上大部分区域是空白的问题，可以在空白区域加一些合适的图片或一些对学生有用的信息，让用户再打开主界面时感觉不会过于单调。
2. 关于这两个按钮的问题，我认为是过于追求简洁所导致，但过分的的简洁往往会导致功能的不清晰，从而适得其反。我的改进建议是在按钮上添加文字，不会占用很大的空间，又会让人清晰易懂。
3. 增加一些新的颜色，不会使用户在进入进入某一界面时颜色非常单调，要是用户停留在任何一个界面时都会有一个良好的视觉感受。
六、实验结论
总结：
我对于此软件的最大感受在于这个软件过分的追求简洁，本来追求简洁并没有什么错误，当今界面设计的潮流便是追求简洁。但在追求简洁化的过程中，有一个原则我们绝对不能忘记，界面是让用户更好的使用才追求简洁，但如果因为追求简洁而让软件功能变得模糊不清，
4
使用户在使用过程中感到不解与困惑，那么简洁便毫无意义。
我们在追求简洁的过程中，更应保证功能的完整性和易于理解性，毕竟界面设计是为了让用户有一个更好的体验。所以保持功能和简洁之间的平衡便显得至关重要，任何界面设计都应考虑这个问题。
这便是我对这个软件的总体评价。
七、实验小结
本次试验了解用户界面设计的基本内容。
