评估移动的系统的可用性提出了新的关注点和问题，对实验室和现场评估方法提出了挑战。最近的一项文献研究表明，大多数移动的人机交互研究项目应用基于实验室的评估。然而，一些研究人员认为，由于移动的系统高度依赖于环境，因此支持实地评估。然而，基于实地的可用性研究很难进行，耗时，而且附加值未知。有助于这一讨论，本文比较了实验室和基于现场的评估相同的上下文感知移动的系统的能力，以确定可用性问题的结果。六个测试对象在实验室使用了移动的系统，而另外六个在现场使用了该系统。结果表明，在现场进行可用性评估的附加值是非常小的，在实验室环境中重新创建使用上下文的中心方面，使相同的可用性问题列表的识别。
Evaluating the usability of mobile systems raises new concerns and questions, challenging methods for both lab and field evaluations. A recent literature study showed that most mobile HCI research projects apply lab-based evaluations. Nevertheless, several researchers argue in favour of field evaluations as mobile systems are highly context-dependent. However, field-based usability studies are difficult to conduct, time consuming and the added value is unknown. Contributing to this discussion, this paper compares the results produced by a laboratory- and a field-based evaluation of the same context-aware mobile system on their ability to identify usability problems. Six test subjects used the mobile system in a laboratory while another six used the system in the field. The results show that the added value of conducting usability evaluations in the field is very little and that recreating central aspects of the use context in a laboratory setting enables the identification of the same usability problem list.
