摘要

为了促进围绕数据的引人入胜和细致入微的对话,我们提供了一种非接触式方法来直接与远程演示中的可视化进行交互。我们将动态图表叠加在演示者的网络摄像头馈馈线上与连续的双手跟踪相结合,展示了突出显示和操作出现在前景中的图表元素的交互。这些互动同时具有功能性和指示性,其中一些允许添加“修辞华丽”,或在谈论数量,类别和时间间隔时使用的表达动作。我们在两项研究中对我们的方法进行了评估,研究对象是经常发表和参加数据报告的专业人士。第一项研究考虑了演示者的视角,其中12名参与者使用包含我们方法的演示环境向远程观众进行演示。第二项研究考虑了17名参与者的听众体验,他们参加了由我们的环境支持的演讲。最后,我们对这些研究的观察结果进行了反思,并讨论了让远程受众参与数据对话的相关含义。

Augmented Chironomia for Presenting Data to Remote Audiences
To facilitate engaging and nuanced conversations around data, we contribute a touchless approach to interacting directly with visualization in remote presentations. We combine dynamic charts overlaid on a presenter’s webcam feed with continuous bimanual hand tracking, demonstrating interactions that highlight and manipulate chart elements appearing in the foreground. These interactions are simultaneously functional and deictic, and some allow for the addition of “rhetorical flourish”, or expressive movement used when speaking about quantities, categories, and time intervals. We evaluated our approach in two studies with professionals who routinely deliver and attend presentations about data. The first study considered the presenter perspective, where 12 participants delivered presentations to a remote audience using a presentation environment incorporating our approach. The second study considered the audience experience of 17 participants who attended presentations supported by our environment. Finally, we reflect on observations from these studies and discuss related implications for engaging remote audiences in conversations about data.
