Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms
研究了如何利用增强现实技术可视化社交媒体数据，帮助应急操作员在危机中快速获取信息、提升态势感知，并基于德国风暴期间的推文分析提出了数据过滤策略。
Abstract During crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefulness of Twitter data for achieving situation awareness and conducted interviews with emergency operators to derive filter strategies for social media data. We synthesized the results by discussing how the unique interface of augmented reality can be used to integrate social media data into emergency control rooms for situation awareness support.
