远程进行可用性测试的想法出现在十年前。从那时起，它已经被经验性地研究，一些软件组织采用远程方法。然而，涉及一种以上远程方法的比较仍然很少。本文介绍了一个系统的实证比较远程可用性测试和传统的实验室为基础的有声思维方法的三种方法的结果。这三种远程方法是远程同步条件和两种远程异步条件，在远程同步条件下，测试是在真实的时间中进行的，但是测试监视器在空间上与测试对象分离，在远程异步条件下，测试监视器和测试对象在空间上和时间上都分离。结果表明，远距离同步方法与常规同步方法实质上是等效的。因此，它有可能方便地让更广泛的用户群体参与可用性测试并支持新的开发方法。异步方法对于测试对象来说要花费更多的时间，并且识别的可用性问题较少，但它们仍然是值得的。
The idea of conducting usability tests remotely emerged ten years ago. Since then, it has been studied empirically, and some software organizations employ remote methods. Yet there are still few comparisons involving more than one remote method. This paper presents results from a systematic empirical comparison of three methods for remote usability testing and a conventional laboratory-based think-aloud method. The three remote methods are a remote synchronous condition, where testing is conducted in real time but the test monitor is separated spatially from the test subjects, and two remote asynchronous conditions, where the test monitor and the test subjects are separated both spatially and temporally. The results show that the remote synchronous method is virtually equivalent to the conventional method. Thereby, it has the potential to conveniently involve broader user groups in usability testing and support new development approaches. The asynchronous methods are considerably more time-consuming for the test subjects and identify fewer usability problems, yet they may still be worthwhile.
