A major challenge, and thus opportunity, in the field of human-computer interaction and specifically usability engineering is designing effective user interfaces for emerging technologies that have no established design guidelines or interaction metaphors or introduce completely new ways for users to perceive and interact with technology and the world around them. Clearly, augmented reality is one such emerging technology. We propose a usability engineering approach that employs user-based studies to inform design, by iteratively inserting a series of user-based studies into a traditional usability engineering lifecycle to better inform initial user interface designs. We present an exemplar user-based study conducted to gain insight into how users perceive text in outdoor augmented reality settings and to derive implications for design in outdoor augmented reality. We also describe lessons learned from our experiences conducting user-based studies as part of the design process.
在人机交互领域，尤其是可用性工程领域，一个重大挑战同时也是机遇在于，为新兴技术设计有效的用户界面。这些新兴技术没有既定的设计准则或交互隐喻，或者引入了用户感知技术及周围世界并与之交互的全新方式。显然，增强现实就是这样一种新兴技术。我们提出一种可用性工程方法，通过将一系列基于用户的研究迭代地插入传统可用性工程生命周期中，以便为初始用户界面设计提供更充分的信息，从而利用基于用户的研究来指导设计。我们展示了一项基于用户的典型研究，该研究旨在深入了解用户在户外增强现实环境中如何感知文本，并得出户外增强现实设计的相关启示。我们还描述了在将基于用户的研究作为设计过程一部分的经历中所学到的经验教训。
