【摘要】 本文首先介绍了自动取款机ATM用户界面可用性研究的主要方法及优缺点。在借鉴这些方法的长处与不足后,我们设计开发出一种基于ATM模拟器的可用性研究辅助工具。该工具可以帮助开发人员和可用性人员方便快捷地进行ATM界面原型设计、可用性评估及修改。我们使用该工具对某ATM产品进行了案例研究,结果表明,该工具起到了较好地辅助可用性研究的作用。更多还原

【Abstract】 Although ATM is now widely in use and very convenient, there are still manypeople in China who don’t use it. We did a study on Chinese users’ banking behaviors forATM and found that the poor usability of ATM user interface is one of the main reasons tohinder people from using it, such as no feedback, not using the users’ language, etc.Researchers abroad have attempted to use different usability methods to improve the usabilityof ATM user interface. Every method is effective, but has its own disadvantages. Learningfrom the advantages and disadvantages of those methods, we develop an ATM simulatorbased tool for usability study. This tool firstly can provide a prototyping framework forinteractive development so that it is easy for developers and usability people to design highfidelity prototypes and modify them; it also can provide a platform for user testing and forrecording the users’ interactive and typical performance data automatically; finally it canreplay the users’ interactive action and form a statistic chart from the performance data. Acase study was then done after the tool developed. We customized a prototype based on apresent ATM user interface flow and employed users to perform 6 different tasks which wererelated to the main transactions that the prototype can supply. A contextual inquiry was alsoconducted after every user’s testing. By the dint of replaying the users’ interactive action,observing the statistic chart and results of contextual inquiries we found several usabilityproblems of the prototype. It has been suggested that the bad error messages and improperlynames of buttons may confuse users or lead them to make mistakes, so they should bemodified. Consequently, from the point of view of the case study, this tool plays a good rolein assisting ATM user interface usability study. More case studies should be done in thefuture.更多还原
