MRI: Acquisition of PI2, a CAVE2-Inspired Display for Discovery Science, Creativity, and Education

一个名为PI2的混合现实环境预计将成为该机构复杂数据分析长期愿景的重要组成部分，实际上是一种人机共生，在这种共生中，人类引导计算机识别潜在感兴趣的特征，然后计算机定位并显示这些特征。发展这一愿景需要在多个领域取得进展，包括半自动特征检测、视觉表示和交互，而传统的显示模式限制了可以显示和感知的内容。此外，该工具还促进了广泛的跨学科研究，并为不同的学生群体提供了一个创新的教学和研究环境。它有助于培训未来几代研究人员在最先进的交互式视觉计算方面进行数据分析，并使更广泛的活动和课程成为可能，并将研究扩展到新的应用程序(例如，通过与史密森博物馆合作，为美国印第安人提供数字人类)。预期包括：-推进目前受阻或严格限制的多种创造性调查途径将迅速取得进展。(该仪器鼓励科学、医疗保健、生物医学、国家安全、人文和教育领域的研究人员进行视觉思维)；-建立不同类别知识发现分析所需的适当技术水平；以及-集合一系列研究项目以调查该仪器的使用情况，以期为许多网络物理和网络人类系统创造一套新颖、明显有用、丰富和富有表现力的技术。PI2是一种混合现实环境，旨在支持交互计算和数字人文领域的研究。该乐器的全立体声和单声道打破了虚拟现实(VR)和瓷砖墙壁显示之间的传统障碍。PI2以前所未有的细节合成、捕获、创建和分析视觉信息的能力可以改变分析师与视觉信息交互的方式。它利用身临其境、混合现实、高分辨率、大视场、大空间和大尺寸、以身体为中心的人机交互以及支持异质数据融合等许多重要特征，使研究领域(如大脑连接组、林地生态、人际体验、生物医学、普遍接入、工程物理、仿真、系统生物学、教育、数字人文、绿色技术和无人驾驶车辆研究)的多个项目受益。该工具汇集了不同的领域：自然语言处理、可穿戴计算、可视化、数据挖掘和交互。

A hybrid-reality environment, named PI2, is expected to become an integral and vital part of a long-term vision for complex data analysis at this institution, in effect, a human-computer symbiosis in which humans guide computers to identify features of potential interest that the computer then locates and displays. Developing this vision requires advances in multiple areas, including semi-automatic feature detection, visual representations, and interaction, where traditional display modalities limit what can be displayed and perceived. Moreover, the instrument also facilitates broad interdisciplinary research and provides an innovative teaching and research environment for a diverse student population. It contributes to train future generations of researchers in state-of-the-art interactive visual computing for data analysis and enables broader activities and courses and expands research to outreach new applications (e.g., digital humanity for the American Indian population by working with the Smithsonian Museums). Expectations include:- Advancing multiple avenues of creative inquiry currently blocked or severely restricted will advance rapidly. (The instrument encourages visual thinking among researchers in sciences, healthcare, biomedicine, national security, humanities, and education); - Establishing appropriate levels of technologies needed for different classes of knowledge discovery analysis; and- Assembling a set of research projects to investigate the use of the instrument with the expectation of creating a novel, demonstrably useful, rich, and expressive set of techniques for many cyber-physical and cyber-human systems. PI2, a hybrid-reality environment, aims to support research in interactive computing and digital humanities. The omni-stereo and mono-modalities of the instrument breaks the traditional barriers between virtual reality (VR) and tiled wall displays. The ability of PI2 to synthesize, capture, create, and analyze visual information in unprecedented detail can transform the way analysts interact with visual information. Leveraging many important characteristics: immersion, hybrid reality, high resolution, large field of view, large space and size, body-centric human-computer interaction, and support for heterogeneous data fusion, it benefits multiple projects in research areas (e.g., brain connectome, woodland ecology, interpersonal experiences, biomedicine, universal access, engineering physics, simulations, systems biology, education, digital humanities, green technologies, and unmanned-vehicle studies). The instrument brings together disparate fields: natural language processing, wearable computing, visualization, data mining, and interaction.
