【摘要】 随着Internet的出现及广泛应用,对网站可用性的研究已经受到越来越多的关注。网站可用性的好坏是网站成功与否的关键。因为网站不同于其它商品,在用户没有购买之前已经开始对网站的可用性进行体验了。在产品设计和软件设计中,客户先付钱,后体验可用性;在网站中,用户先体验可用性,后付钱,因此提高网站的可用性显得异常重要。所谓网站可用性就是用户能否在网站上方便快捷地找到所需要的信息或完成预定的任务,并且在网站浏览过程中有轻松愉快的体验。在如今这个惜时如金的年代,人们会将宝贵的时间花在那些可用性好的网站上,并且尽量避免浏览那些粗糙、使用起来不舒适的网站。本文从工业界对可用性的实际需求和当前国内可用性专家缺乏的现状考虑,利用计算机在存储和计算方面的优势,在Windows平台下设计开发了可以辅助进行可用性测试分析的工具——UBAT(User Behavior Analysis Tool)。UBAT可以采集关于网站用户行为的背景流、鼠标流,用户对网站的关注点等数据,并可以进行远程的用户测试、在线交流及行为数据回放功能。文章首先介绍了可用性、用户行为、网站用户行为的分类等基本概念,接着作者提出基于客户端用户行为记录的网站可用性评估方法。然后作者重点介绍了关于UBAT工具的实现过程和利用UBAT工具进行的两个试验性应用案例。第一个案例是利用UBAT在客户端记录用户行为功能考查国内最大的C2C电子商务网站(淘宝网)的可用性,第二个案例是利用UBAT工具搜集鼠标流数据功能来研究用户对不同网页布局上文本和图片的关注程度。这两个案例的测试结果表明UBAT工具能够帮助可用性测试人员提高工作效率,节省费用,并可以发现一些使用传统方法难以发现的可用性问题。更多还原

【Abstract】 With the appearance and widely application of the Internet, more and more people pay attention to the research on website usability which is a key to decide whether a website is good or not. For website, users experience usability of it through surfing web pages before purchase, which differs from other commodity, you have to purchase it then you start to use it and experience usability. So improving the website usability becomes very important. A so-called website with good usability is a website where users can find information easily and finish any task as soon as possible with satisfied experience. Time become more valuable in these years, so nobody would like to visit website with bad usability which will kill more time for finding information or something. The author develops an aid usability testing tool—UBAT (User Behavior Analysis tool) on the platform of Windows from the point of usability requirement in industry and the lack of usability experts in home. UBAT can capture stream of background, stream of mouse, the spot of notice etc. and it can also provide the function of remote testing, online direction and storage user behavior data. This paper introduces the concepts of the usability, user behavior, user behavior sorting and so on, and then puts forward web usability evaluating methods based on user behavior. Finally, the paper introduces the process of developing UBAT and two examples of usability testing with UABT. One is about TAOBAO, the other is about the spot of users’ notice by simulating eye tracking, which proves the UBAT is helpful for usability testing. On the one hand UBAT improve the efficiency of usability testing. On the other hand UBAT save a lot of money and help the usability experts find some usability problems which are very hard to find through other traditional methods.更多还原
