Creating and Evaluating New Media Interfaces for Expression

我建议突破两种互动视觉媒体的界限，以增加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，先进的互动、协作视频（IV）将被创造出来，其中有三个关键的新功能，将视频提升为“一流”的学习媒介。首先，利用我们的3D鱼缸虚拟现实（FTVR）球形显示器（3DD）进行的研究主要集中在两种主要的交互类型上：1)需要实时3D捕获的同地和远程多人交互，以及2)人-三维代理交互。为了支持同时定位的四人互动，将创建一个弯曲偏光透镜来匹配球面显示表面的曲率，从而使四个不同的单视角校正视图投射到显示器上，但不同的用户可以看到。这些显示器提供的虚拟内容固定在现实世界的坐标上，允许每个人共享一个共同的参考框架。因此，指示互动，如指着说“那东西在那里”，是支持的，每个人都可以看到被指着的是什么。对于远程参与者，将创建一个使用支持眼睛接触的深度相机的实时3D捕捉系统。将研究3D任务的感知效果以及任务性能，并将其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，语音和手势交互将被研究。同样，用于协作指向、选择、翻译和旋转内容的交互语义将在远程和同地场景中进行探索。这项研究将创造先进的3D球形显示器，供人群和代理人跨越空间和时间工作和玩耍。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功能缺失：可变性、双向性和互操作性。对于可变性，将创建在管理每个状态更改和注释时用于协作视频制作的接口。在互操作性方面，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，将研究支持与视频元素通信的复杂方法的丰富引用接口。这些互动将在教育场景中进行研究，例如：记笔记、演讲和社交学习。最终，这项研究的目标是为视频提供“笔和纸”，这样人们就可以像通过文本一样轻松地学习“阅读/观看和写作/撰写”视频。这项研究直接涉及33名高素质的人才，他们在世界级的国际跨学科团队中工作，成为先进媒体互动的领导者。

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.
