论文摘要
在过去的两年中，新兴的HCI工作集中在课堂上 - 教师如何分配课堂不同地区学生的时间和关注。跟踪和可视化这一隐含但相关的教学维度可以使研究和教师专业化受益。先前的工作证明了描绘教师下落的价值。然而，在设计新的合成可视化的设计中仍然存在一个主要的机会，可以帮助研究人员和从业人员在广泛的跟踪数据中获得更多见解。我们提出了蒲公英图，这是一种合成的热图技术，结合了教师的定位和定位（标题）数据，除了Whereabouts之外，还提供了更丰富的代表，例如，教师的注意力模式（他们正在照顾的指示）以及他们的活动性模式（即在课堂上的轨迹）。本文利用现场研究中的各种课堂数据说明了蒲公英图的设计和实用性。
In the past two years, an emerging body of HCI work has been focused on classroom proxemics - how teachers divide time and attention over students in the different regions of the classroom. Tracking and visualizing this implicit yet relevant dimension of teaching can benefit both research and teacher professionalization. Prior work has proved the value of depicting teachers' whereabouts. Yet a major opportunity remains in the design of new, synthesized visualizations that help researchers and practitioners to gain more insights in the vast tracking data. We present Dandelion Diagram, a synthesized heatmap technique that combines both teachers' positioning and orientation (heading) data, and affords richer representations in addition to whereabouts - For example, teachers' attention pattern (which directions they were attending to), and their mobility pattern (i.e., trajectories in the classroom). Utilizing various classroom data from a field study, this paper illustrates the design and utility of Dandelion Diagram.
