标题： Audience Amplified: Virtual Audiences in Asynchronously Performed AR Theater

摘要： 观众的反应可以显著提升现场体验；相反，在任何时间、任何地点的增强现实（AR）体验中，大型人群可能并不总是能够聚集在一起。 为了更接近模拟有大量观众的现场活动，我们创建了一个移动AR体验，用户可以自然地四处走动，并通过使用模仿学习从真实观众中训练出的虚拟观众参与AR戏剧。 这使我们能够仔细捕捉人工智能（AI）观众中人类不完美和行为的本质。 结果是一种新颖的移动AR体验，孤独的AR用户可以在物理空间中与虚拟观众一起体验增强表演。 虚拟舞者从周围环境中出现，伴随着数字模拟的观众，提供一种类似于沉浸式戏剧的社区体验。 在一项初步研究中，模拟的人类角色被广泛偏好于仅有的观众音频评论。 随后，我们邀请了20名参与者作为AR舞蹈表演的观众，将无观众条件与六名旁观者的模拟观众进行比较。 通过问卷和体验报告，我们研究了用户反应和行为。 我们的结果显示，虚拟观众成员的存在使得观众认为表演是一种社交体验，对活动的兴趣和参与度有所增加。 另一方面，对于一些观众来说，没有虚拟观众的舞蹈表演引发了更强的积极情绪。 显示英文摘要

摘要： Audience reactions can considerably enhance live experiences; conversely, in anytime-anywhere augmented reality (AR) experiences, large crowds of people might not always be available to congregate. To get closer to simulating live events with large audiences, we created a mobile AR experience where users can wander around naturally and engage in AR theater with virtual audiences trained from real audiences using imitation learning. This allows us to carefully capture the essence of human imperfections and behavior in artificial intelligence (AI) audiences. The result is a novel mobile AR experience in which solitary AR users experience an augmented performance in a physical space with a virtual audience. Virtual dancers emerge from the surroundings, accompanied by a digitally simulated audience, to provide a community experience akin to immersive theater. In a pilot study, simulated human avatars were vastly preferred over just audience audio commentary. We subsequently engaged 20 participants as attendees of an AR dance performance, comparing a no-audience condition with a simulated audience of six onlookers. Through questionnaires and experience reports, we investigated user reactions and behavior. Our results demonstrate that the presence of virtual audience members caused attendees to perceive the performance as a social experience with increased interest and involvement in the event. On the other hand, for some attendees, the dance performances without the virtual audience evoked a stronger positive sentiment.
