Think-Aloud测试是一种广泛使用的可用性评估方法，但很少研究其在实践中的使用。我们报告了14个思考会议的探索性研究，详细检查了其录音。该研究表明，对思想相关课程进行的观察的立即分析只有偶尔的话，如果有的话。在测试时，评估人员似乎寻求确认他们已经意识到的问题。在测试过程中，评估人员经常向用户询问他们的期望和假设情况，而不是关于经历的问题。此外，评估人员对经过测试系统的可用性有了很多了解，但对其效用知之甚少。该研究表明，关于可用性评估的文献中很少讨论的实际现实如何影响会议。我们讨论对可用性研究人员和专业人士的影响，包括用于快节奏分析的技术以及在会议期间捕获观察的工具。
Think-aloud testing is a widely employed usability evaluation method, yet its use in practice is rarely studied. We report an explorative study of 14 think-aloud sessions, the audio recordings of which were examined in detail. The study shows that immediate analysis of observations made in the think-aloud sessions is done only sporadically, if at all. When testing, evaluators seem to seek confirmation of problems that they are already aware of. During testing, evaluators often ask users about their expectations and about hypothetical situations, rather than about experienced problems. In addition, evaluators learn much about the usability of the tested system but little about its utility. The study shows how practical realities rarely discussed in the literature on usability evaluation influence sessions. We discuss implications for usability researchers and professionals, including techniques for fast-paced analysis and tools for capturing observations during sessions.
