新闻报道中沉浸式信息图的评估：量化移动AR具象尺度信息图对体积理解的影响
An Evaluation of Immersive Infographics for News Reporting: Quantifying the Effect of Mobile AR Concrete Scales Infographics on Volume Understanding
AI总结：
本研究针对新闻报道中的沉浸式信息图，通过26人参与的受控实验对比文本类比、图像信息图与移动AR信息图的体积理解效果，发现AR信息图误差比静态图低31.8%，可提升读者对新闻体积信息的理解能力。
摘要：
增强现实（AR）能够在用户自身所处环境中呈现信息，从而传递出对信息真实物理尺度的直观感受。新闻从业者正越来越多地通过沉浸式信息图利用这一优势——这类信息图是传统信息图的延伸，依托大众熟悉的参照对象来传达体积、高度、重量与尺寸信息。本研究旨在衡量沉浸式移动AR具象尺度信息图对用户理解信息尺度的作用。鉴于当前基于平板电脑的移动AR在新闻消费场景中的普及度远高于头显式AR，研究聚焦于平板端移动AR驱动的信息图。我们设计并搭建了一套实验装置，针对三篇特征与尺度各异的新闻，设置了三种备选呈现方式：文本类比、图像信息图与AR信息图。在一项受控用户研究中，我们邀请26名参与者借助AR移动应用，在真实环境中标示出他们所理解的新闻信息对应的预期体积，同时对比了他们与不同呈现形式交互时的主观感受。结果显示，在不同类型的新闻中，图像信息图与AR信息图的理解效果均显著优于单纯的文本类比；而AR信息图的体积估算误差平均比静态图像信息图低31.8%。研究结果表明，移动AR具象尺度信息图能够提升读者对体积信息的理解能力，可为新闻报道提供助力。
英文摘要：
Augmented Reality (AR) allows us to represent information in the user's own environment and, therefore, convey a visceral feeling of its true physical scale. Journalists increasingly leverage this opportunity through immersive infographics, an extension of conventional infographics reliant on familiar references to convey volumes, heights, weights, and sizes. Our goal is to measure the contribution of immersive mobile AR concrete scales infographics to the user's understanding of the information scale. We focus on infographics powered by tablet-based mobile AR, given its current much more widespread use for news consumption compared to headset-based AR. We designed and implemented a study apparatus containing three alternative representation methods (textual analogies, image infographic, and AR infographic) for three different pieces of news with different characteristics and scales. In a controlled user study, we asked 26 participants to represent the expected volume of the information in the real world with the help of an AR mobile application. We also compared their subjective feelings when interacting with the different representations. While both image and AR infographics led to significantly better comprehension than textual analogies alone across different kinds of news, AR infographics led, on average, to a 31.8% smaller volume estimation error than static ones. Our findings indicate that mobile AR concrete scales infographics can contribute to news reporting by increasing readers' abilities to comprehend volume information.
