论文摘要
在实验文本输入方法的实验室研究中，观察者很少有参与者的键入错误 - 用户倾向于在实验室中非常仔细地输入。当未测试支持机制时，调查支持错误意识或校正的方法时，这是一个问题。我们设计了一种新颖的评估方法，该方法是基于将错误注入用户的打字流中，并报告了有关该技术有效性的两项用户研究。注射使我们能够观察到更多的实例和更多类型的误差校正行为，而不是在单个研究中可能会出现的，而不会对关键输入行为特征产生重大影响。两项研究的定性反馈都表明，我们的注射算法成功地创建了对参与者现实的错误。误差喷射的使用显示出对文本输入研究中错误校正行为的研究的希望。
During lab studies of text entry methods it is typical to observer very few errors in participants' typing - users tend to type very carefully in labs. This is a problem when investigating methods to support error awareness or correction as support mechanisms are not tested. We designed a novel evaluation method based around injection of errors into the users' typing stream and report two user studies on the effectiveness of this technique. Injection allowed us to observe a larger number of instances and more diverse types of error correction behaviour than would normally be possible in a single study, without having a significant impact on key input behaviour characteristics. Qualitative feedback from both studies suggests that our injection algorithm was successful in creating errors that appeared realistic to participants. The use of error injection shows promise for the investigation of error correction behaviour in text entry studies.
