视觉查询系统（VQSS）使用户能够交互式地搜索具有所需的视觉模式的线图，通常使用基于直观的草图接口指定。尽管过去数十年的VQSS工作，但这些努力并未在实践中转化为采用，这可能是因为VQS在基于实验室的不切实际的环境中得到了很大的评估。为了解决这种差距，我们与来自三个不同领域的专家进行了合作，一个以用户为中心的设计过程，以支持其工作流程和分析需求的VQS，并评估如何在VQS中使用VQSS，并评估VQSS在一个以用户为中心的设计过程，并实践。我们的研究结果表明，仅临时素描的查询不像先前的工作所建议的那样常用，因为分析师通常无法精确表达其感兴趣的模式。此外，我们表征了由增强的VQ支持的三个基本的感官过程。我们发现，参与者采用了所有三个过程，但是根据每个领域的分析需求，以不同的比例。我们的发现表明，必须集成所有三个感官过程，以使未来的VQS对于广泛的分析查询有用。
Visual query systems (VQSs) empower users to interactively search for line charts with desired visual patterns, typically specified using intuitive sketch-based interfaces. Despite decades of past work on VQSs, these efforts have not translated to adoption in practice, possibly because VQSs are largely evaluated in unrealistic lab-based settings. To remedy this gap in adoption, we collaborated with experts from three diverse domainsastronomy, genetics, and material sciencevia a year-long user-centered design process to develop a VQS that supports their workflow and analytical needs, and evaluate how VQSs can be used in practice. Our study results reveal that ad-hoc sketch-only querying is not as commonly used as prior work suggests, since analysts are often unable to precisely express their patterns of interest. In addition, we characterize three essential sensemaking processes supported by our enhanced VQS. We discover that participants employ all three processes, but in different proportions, depending on the analytical needs in each domain. Our findings suggest that all three sensemaking processes must be integrated in order to make future VQSs useful for a wide range of analytical inquiries.
