尽管可视化设计模型在文献中以更高级别的方法框架的形式存在，但这些模型并没有为领域表征步骤提供明确的方法学规定。本文提出了问题驱动的可视化应用程序设计中需求工程的框架和端到端模型。该框架和模型基于以活动为中心的设计范式，是对以人为中心设计的增强。建议的以活动为中心的方法关注用户任务和活动，并允许在需求工程过程与现有的、更高级别的可视化设计模型的抽象阶段及其评估之间建立明确的联系。与现有的可视化设计模型不同，最终的模型：基于用户活动为可视化赋值；将用户任务排在用户数据之前；将需求划分为与活动相关的功能以及非功能特征和约束；并明确地将用户工作流合并到需求流程中。该模型的另一个优点是它明确地将功能规范集成到可视化设计嵌套模型中，这是本工作从软件工程文献中采用的一个概念。使用两套跨学科项目的量化评估支持以活动为中心的模式的优点。其结果是面向问题驱动的数据可视化的可视化设计的领域表征步骤的实用路线图。遵循这个领域表征模型可以帮助消除可视化设计文献中多次发现的许多陷阱。
Although visualization design models exist in the literature in the form of higher-level methodological frameworks, these models do not present a clear methodological prescription for the domain characterization step. This work presents a framework and end-to-end model for requirements engineering in problem-driven visualization application design. The framework and model are based on the activity-centered design paradigm, which is an enhancement of human-centered design. The proposed activity-centered approach focuses on user tasks and activities, and allows an explicit link between the requirements engineering process with the abstraction stage—and its evaluation—of existing, higher-level visualization design models. In a departure from existing visualization design models, the resulting model: assigns value to a visualization based on user activities; ranks user tasks before the user data; partitions requirements in activity-related capabilities and nonfunctional characteristics and constraints; and explicitly incorporates the user workflows into the requirements process. A further merit of this model is its explicit integration of functional specifications, a concept this work adapts from the software engineering literature, into the visualization design nested model. A quantitative evaluation using two sets of interdisciplinary projects supports the merits of the activity-centered model. The result is a practical roadmap to the domain characterization step of visualization design for problem-driven data visualization. Following this domain characterization model can help remove a number of pitfalls that have been identified multiple times in the visualization design literature.
