Creating and Evaluating New Media Interfaces for Expression

我建议推动两种形式的互动视觉媒体的界限，以提高人类学习和共同工作的能力。首先，将研究与新型3D显示器的新交互形式。第二，将创建先进的互动、协作视频（IV），其中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）的研究集中在两种主要类型的交互：1）共同定位和远程多人交互需要实时3D捕捉，2）人-3D代理交互。为了支持协同定位的四人交互，将创建弯曲偏振透镜以匹配耦合到有源眼镜的球形显示表面的曲率，以使得四个不同的单视场透视校正视图能够被投影在显示器上但被不同的用户看到。这些显示器提供锚定到真实世界坐标的虚拟内容，允许每个人共享一个共同的参考框架。因此，指示语的互动，比如指向并说“那个东西在那里。“在每个人都能看到所指的地方得到支持。对于远程参与者，将创建一个使用深度相机支持眼神接触的实时3D捕获系统。感知效果以及对3D任务的任务性能将进行研究，并与使用平面屏幕的类似配置进行比较。其次，观众和房间的互动与智能虚拟代理（IVA）内的球形显示器将进行研究。与真实参与者一样，语音和手势交互将被研究。同样，协作指向，选择，翻译和旋转内容的交互语义将在远程和协同定位的情况下进行探索。这项研究将为一群人和代理人创造先进的3D球形显示器，以跨空间和时间工作和娱乐。 其次，从过去的工作中，我们发现三个视频启示教育的关键是失踪：可变性，双向性和互操作性。对于可变性，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）进行有效整合。对于双向性，将研究能够实现与视频元素通信的复杂方法的丰富参考接口。这些互动将在教育场景中进行研究，例如：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”，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名高素质的人员，他们在世界一流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.
