CISE Research Infrastructure: Pervasive Pixels

EIA 02-02063 Schulzrinne，HenningFeiner，Steven K.，Kaiser，Gail E.，Kender，John R.，McKeown，Kathen R.Boston大学标题：国际扶轮社：普及像素项目建议：这个项目，开发一个灵活的部门范围的协同工作基础设施，“普及像素”，将作为协同系统研究的试验台，旨在使用这个协同框架来进行研究和教学。无处不在的像素将跨不同的网络和设备捕获和传输多媒体信息。该系统将安排会议、管理和预取多媒体对象，并在单独和共享的显示器上展示材料。会议可以根据用户的意愿进行定位、跟踪和识别，并进行记录、注释和汇总，并具有广泛的研究能力。虽然核心计算和通信技术的改进鼓励远程工作和交互，但参与跨建筑物、城市和国家/地区的跨学科协作时，通常会遇到当前协作支持系统施加的严重限制。普适像素是为了解决这些问题而产生的，应该能够通过不同种类的网络、客户端和设备捕获和传递多媒体信息(包括视频)；根据工作流程需求的模型以及时间、空间和语义相互关系的模型，安排会议、管理和预取工作文档和多媒体对象，并布置单独和共享显示的材料；通过在实况和捕获的视频和音频中定位、跟踪和识别用户并理解他们的手势来促进会议；从多个物理角度并通过多种类型的数据库查询记录、注释、汇总和搜索会议内容，从而最大限度地发挥时差的影响。基础设施强调在不同位置的大型、仪表化、多显示工作空间，以适应小组互动。各种容量的联网移动设备，可单独使用，也可在更大的工作空间环境中使用。对地点、平台或组组成的变化具有透明和自动的适应性，允许移动用户在移动时进行交互，而不必手动考虑这些变化。支持广泛的硬件和软件，从商业现成的商品组件开始，在系统发展的同时保留其功能，最终导致满足环境的新标准。

EIA 02-02063Schulzrinne, HenningFeiner, Steven K., Kaiser, Gail E., Kender, John R., McKeown, Kathleen R. Boston University Title: RI: Pervasive PixelsProjected Proposed:This project, developing a flexible department-wide collaborative work infrastructure, "Pervasive Pixels," that will serve as a testbed for research in collaborative systems, aims to use this collaborative framework to conduct research and teaching. Pervasive Pixels will capture and deliver multimedia information across heterogeneous networks and devices. The system will schedule meetings, manage and prefetch multimedia objects, laying out material on individual and shared displays. Meetings are facilitated by locating, tracking and identifying users as they desire and are recorded, annotated and summarized, with extensive research capabilities. While improvements in core computation and communication technologies encourage working and interacting remotely, engaging in interdisciplinary collaborations that span buildings, cities, and countries, routinely encounters severe limitations imposed by current collaboration support systems. Pervasive Pixels is created to address these problems and should make possible Capturing and delivering multimedia information (including video), through heterogeneous networks, clients, and devices; Scheduling meetings, managing and prefetching work documents and multimedia objects, and laying out materials of individual and shared displays, based on models of workflow needs and models of temporal, spatial, and semantic interrelationships; Facilitating meetings by locating, tracking, and identifying users, and understanding their gestures, in live and captured video and audio; Recording, annotating, summarizing, and searching meeting content, from multiple physical perspectives and via multiple types of database queries, thus maximizing the effects of temporal differences.The infrastructure emphasizes Large, instrumented, multi-display workspaces in a variety of locations, to accommodate group interactions. Networked mobile devices of various capacities, used individually and in the context of larger workspaces. Transparent and automatic adaptability to changes of place, platform, or group composition, allowing mobile users to interact as they move about, without having to account for these changes manually. Support a wide range of hardware and software, beginning with commercial off-the-shelf commodity components, whose capabilities are retained while the system evolves, ultimately leading to new standards for meeting environments.
