计算机视觉和模式识别越来越多地被针对普通用户的智能手机和平板电脑应用所采用。一个开放的设计挑战是使这样的系统易于理解，而不需要用户成为技术专家。本文报道了一项实验室研究，研究视觉反馈的作用。我们的研究结果表明，从反馈的处理阶段，用户的能力，发展连贯和正确的理解系统的操作中起着重要的作用。我们研究的参与者表现出误解反馈所传达的含义的倾向，将其与处理结果和更高层次的概念联系起来，而实际上反馈代表的是低层次的特征。根据实验结果和收集的定性数据，我们讨论了围绕模式匹配算法设计交互的挑战。
Computer vision and pattern recognition are increasingly being employed by smartphone and tablet applications targeted at lay-users. An open design challenge is to make such systems intelligible without requiring users to become technical experts. This paper reports a lab study examining the role of visual feedback. Our findings indicate that the stage of processing from which feedback is derived plays an important role in users' ability to develop coherent and correct understandings of a system's operation. Participants in our study showed a tendency to misunderstand the meaning being conveyed by the feedback, relating it to processing outcomes and higher level concepts, when in reality the feedback represented low level features. Drawing on the experimental results and the qualitative data collected, we discuss the challenges of designing interactions around pattern matching algorithms.
