I propose to push the boundaries of two forms of interactive visual media to increase the capacity for humans to learn and work together. First, new forms of interaction with a novel 3D display will be investigated. Second, advanced interactive, collaborative video (IV) with three critical new affordances to elevate video to be a `first-class' learning medium will be created. First, research using our 3D fish-tank virtual reality (FTVR) spherical display (3DD) focuses on two main types of interactions: 1) co-located and remote multi-person interaction requiring real-time 3D capture, and 2) human-3D agent interaction. To support co-located four-person interaction, a curved polarizing lens will be created to match the curvature of the spherical display surface coupled to active glasses to enable four different monoscopic perspective corrected views to be projected on the display but seen by different users. These displays provide virtual contents anchored to real-world coordinates allowing everyone to share a common reference frame. Thus, deictic interactions, like pointing and saying "That thing there." are supported where everyone can see what is being pointed at. For remote participants, a real-time 3D capture system using depth cameras supporting eye-contact will be created. Perceptual effects as well as task performance on 3D tasks will be studied and compared to similar configurations using flat screens. Second, viewer and room interaction with an intelligent virtual agent (IVA) inside the spherical display will be studied. As with real-participants, voice and gesture interaction will investigated. Likewise, interaction semantics for collaborative pointing, selecting, translating, and rotating content will be explored in remote and co-located scenarios. This research will create advanced 3D spherical displays for groups of people and agents to work and play across space and time. Second, from past work, we discovered three video affordances critical for education are missing: mutability, bidirectionality and interoperability. For mutability, interfaces for collaborative video making while each state change and annotation is managed will be created. For interoperability, interfaces supporting video structure and semantic capture and copy for effective integration with students' information ecology, including notes will be created. For bidirectionality, rich referencing interfaces enabling complex methods of communicating with video elements will be investigated. These interactions will be studied in educational scenarios such as: note taking, presenting, and social learning. Ultimately, the goal of this research provides the `pen and paper' for video so people can learn to `read/watch and write/compose' video as easily as they can through text. This research directly involves 33 highly qualified personnel working in world-class international, interdisciplinary teams to become leaders in advanced media interaction.

我建议突破两种形式的交互式视觉媒体的界限，以提高人类学习和合作的能力。首先，将研究与新型 3D 显示器交互的新形式。其次，将创建先进的交互式协作视频（IV），其具有三个关键的新功能，可将视频提升为“一流”的学习媒体。首先，使用我们的 3D 鱼缸虚拟现实 (FTVR) 球形显示器 (3DD) 进行的研究重点关注两种主要类型的交互：1) 需要实时 3D 捕获的同地远程多人交互，以及 2) 人与 3D 代理交互。为了支持共处一地的四人互动，将创建一个弯曲的偏光透镜，以匹配与主动式眼镜耦合的球形显示表面的曲率，从而使四种不同的单视场透视校正视图能够投影在显示器上，但由不同的用户看到。这些显示器提供锚定到现实世界坐标的虚拟内容，允许每个人共享一个共同的参考系。因此，指示性互动，比如指着并说“那儿的东西”。受到支持，每个人都可以看到所指向的内容。对于远程参与者，将创建一个使用支持眼神接触的深度相机的实时 3D 捕获系统。将研究 3D 任务的感知效果和任务表现，并与使用平面屏幕的类似配置进行比较。其次，将研究观看者和房间与球形显示器内的智能虚拟代理（IVA）的交互。与真实参与者一样，我们将研究语音和手势交互。同样，将在远程和同地场景中探索协作指向、选择、翻译和旋转内容的交互语义。这项研究将为人群和代理创建先进的 3D 球形显示器，以便他们跨空间和时间工作和娱乐。 其次，从过去的工作中，我们发现对教育至关重要的三个视频可供性缺失：可变性、双向性和互操作性。为了实现可变性，将创建用于协作视频制作的接口，同时管理每个状态更改和注释。为了实现互操作性，将创建支持视频结构和语义捕获和复制的接口，以便与学生的信息生态（包括笔记）有效集成。对于双向性，将研究丰富的参考接口，支持与视频元素通信的复杂方法。这些交互将在教育场景中进行研究，例如：记笔记、演示和社交学习。最终，这项研究的目标是为视频提供“笔和纸”，以便人们可以像通过文本一样轻松地学习“阅读/观看和书写/撰写”视频。 这项研究直接涉及世界一流的国际跨学科团队中的 33 名高素质人员，他们将成为先进媒体互动领域的领导者。
