HFI原来有一篇文章讲到了眼睛scan的特征,左对齐更适应这种方式。但是我的同事说右对齐更neat和左对齐时Localization时文本长度的制约性。标兵Microsoft一直挺坚持左对齐的。国内网站的表单,却多采用右对齐。。

LukeW的演讲解答了一个多年来在世界ui界都一直争论不休的问题。左对齐,右对齐,还是顶对齐?

The slides in Figures 29–31 cover the pros and cons of different alignments for labels in forms. “Top-aligned labels” that are left-aligned above input fields offer the best performance, followed by ...

*The first and most important impact is whether we helped / hindered in shipping our product.  We define “helped” as: 
可用性实践者不仅要处理很多的可用性研究,而且要会写好的报告给上司,帮助他们权衡研究数据和结论的优点缺点。这份报告的技巧绝对是有价值的。下面给出一些提示帮助你的文档包含那些关键的内容。

These checkpoints are based on the work of Julian Meltzoff (1997).

The checkpoints

  • Is the research question clearly stated?
  • Does the introduction, statement of the problem, and overview of any literature or previous reports adequately set the background for the reader, and is this material consistent with the research question?
  • Is it clear why the study was conducted?
  • Given the research question and the background material are the research hypotheses and objectives appropriate and clearly stated?
  • Are key terms well defined?
  • Is the independent variable appropriate given the question of the study? Are the levels of the independent variable appropriate?
  • Is the dependent variable appropriate for the study?
  • Are the criterion measures of the dependent variable appropriate, valid, and reliable?
  • Are the scoring, rating, and judging procedures valid and reliable?
  • Is the measuring apparatus (if any) accurate and reliable?
  • Are the controls appropriate? Can the results be affected by variables that have not been controlled? Are the controls or control groups (if used) properly selected?
  • Is the research design suitable to meet the objectives of the study? Is the research design appropriate to test the hypotheses and answer the research question?
  • Are the methods and procedures clearly described in sufficient detail to be understood and replicated?
  • Is the presentation sequence of test stimuli (including any randomisations or counter-balancing) appropriate?
  • Are the test participants properly oriented and motivated? What is their understanding of the task? Are the instructions sufficiently clear and precise?
  • Are there any signs of experiment bias in the design, data collection, assessment, analysis, or reporting?
  • Are the participants properly selected? Is the sample representative and unbiased? Do the procedures adhere to the guidelines for the protection and well being of participants?
  • Is the sample size appropriate? Are the appropriate procedures used to assign participants to groups, treatments, or conditions? Are suitable techniques used to establish group equivalence, such as matching, equating, or randomising?
  • Does participant attrition occur and if so does it bias the sample?
  • Are bad data properly identified and set aside (not included in the final test data set); and are instances of bad data reported and explained as such?
  • Have the data been appropriately analysed, sorted, categorised, grouped, prioritised etc.?
  • Are descriptive statistics used? Are these accurate?
  • Are the inferential statistical tests appropriate? Are the assumptions for their use met? Are there any errors in the calculation or presentation of statistical results?
  • Are all graphs correctly labelled (both the X and Y axes)? Are data elements on graphs properly coded, and identified?
  • Are tables and figures clearly labelled and accurately presented and referenced in the text? Are results and findings correctly interpreted, properly reported, given meaning and placed in context?
  • Are recommendations unambiguous? Do recommendations follow clear usability, human factors, or ergonomics guidelines?
  • Are recommendations supported by references to prior literature or to industry standards?
  • Is the discussion section of the report reasonable in view of the data?
  • Are the conclusions valid and justified by the data?
  • Are the generalizations valid?
  • Do references (if used) match the citations in the text?
  • Have ethical standards been adhered to in all phases of the research?
  • What can be done to improve or re-design the study?

做完用户测试之后

 一则读书笔记。
对你的用户做完了测试后,要确认一下自己是否已经弄清楚的这些问题。一个个对照,问一下自己,看看自己的用户测试效果如何。

uu网看到一篇文章,关于用户满意度调查在一个渐变网站评估中的迭代使用

改版的案例是:IBM的易用(EOU)网站(http://www.ibm.com/easy )。该网站的目的是宣传IBM在产品易用性方面的工作。从1997年由IBM主要为人机交互领域的实践人员提供信息,后来战略转变,被设计成为更广泛的读者群服务,包括界面设计师、信息开发人员、人因从业者、技术记者、程序员、IT经理以及这些专业的教师和学生。这个网站还随着IBM网站设计标准的演变而采用相应的新界面风格。

本文对EOU网站不同设计的三次系列用户满意度调查的方法和用法进行了讨论。挺不错的文章。

在ZDnet China上看到一篇文章,之前就看过,不过还是觉得作为笔记记下来比较好。觉得比较重要的几点,都用不同的颜色给与了标注。作者: Builder.comSunday, October 10 2004 10:28 AM ..............

可用性评估-开篇

Tag: [ 可用性 ]
Ryana 发表于13:46
    长期使用一个产品久了,人就会主动去适应,哪怕它不合理,随着熟练程度的提高,对产品的依赖感甚至让人觉得这个类型的产品就该是这个样子,对其他的产品嗤之以鼻。作为产品经理或者交互设计师,应该尽可能的尝试相关产品,特别是那些比较有特色的,做出相应的评估,给将要开发的产品一开始定位就是超越所有同类型的,做业界最好的。    在评估中,要做到的很重要的一是摒弃权威崇拜的思..............
学习文章:[Use Experience Design]    UX即User Experience,在http://www.uxnet.org/首页有一段解释,什么是UX,它已经从原来仅限于信息技术领域扩大出来。UX关注的改进设计凡是用户可以体验的:网站、玩具、博物馆等等,属于交叉学科。原文如下:User Experience (UX) is an emerg..............
