ITR: Wireless Client-server Technologies for Ubiquitous Multimedia Computing

密歇根州立大学(MSU)的计算机科学与工程系和电信系请求支持，以进行涉及以下类别的研究：人机界面、信息管理和可扩展信息基础设施。三个现有的研究实验室将被连接起来并用作试验台，以促进这种协作的跨学科研究：高速网络与性能实验室(HSNP)、媒体与娱乐技术实验室(MET)以及媒体接口与网络设计实验室(MEND)。拟议研究的一个主要目标是进一步推进用于无处不在的多媒体计算环境的客户端-服务器技术。由于无处不在的计算能力可能采取高级个人数字化助理(PDA)、具有平视显示器的可穿戴计算机系统或论证的现实系统的形式，该提案解决了关键问题，包括：(1)个人环境数据捕获，(2)环境数据显著，(3)在客户-服务器环境中通过无线和异类网络系统传输多媒体数据，(4)媒体访问和检索，以及(5)人机界面(HCI)设计和分析。该项目涉及的一些重要问题是：(A)在连续的音频和视频捕获的情况下，在个人多媒体数据库中存档的最佳内容是什么？(B)如何使用不受限制内容的音频和视频捕获作为多媒体数据库的有效查询机制？(C)在带宽、错误率和延迟不断变化且取决于许多环境条件的无线环境中，如何优化感知的延迟和通信性能？(D)如何使用异类网络和无线网络系统来保证实时多媒体流量传输的服务质量？以及(E)应采用什么设计原则来支持完全移动的用户参与免提高带宽、协作工作和通信？将开发和测试新的算法和技术，以通过模拟、仿真或实验来解决这些问题。预计现有设施将通过国家科学基金会一项未决的研究设备提案得到显着增强。这些拟议的设备(例如，VoD服务器、多媒体笔记本电脑、WaveLan产品、可穿戴式可论证现实界面)将成为支持复杂试验床的决定性基础设施，通过无线链路连接三个研究实验室(HSNP、MET、Mind)。多实验室试验台将用于该项目的实验阶段。为了扩大对我们研究的参与，私人投资机构将邀请感兴趣的教师(通过为期两周的暑期研讨会)和来自HBCU(历史上的黑人学院和大学)的学生(通过为期十周的暑期研究经验)在三个夏天与他们合作。此外，投资推广署亦会邀请数名有兴趣的业界专业人士参与研究工作。

The Computer Science and Engineering, and Telecommunication Departments at Michigan State University (MSU) requested support to conduct research involving the categories: Human-Computer Interface, Information Management, and Scalable Information Infrastructure. Three existing research laboratories will be connected and used as a testbed to facilitate this collaborative interdisciplinary research: High-Speed Networking & Performance Lab (HSNP), Media and Entertainment Technologies Lab (MET), and Media Interface and Network Design Lab (MIND). A primary objective of the proposed research is to further advance the client-server technologies for a ubiquitous multimedia computing environment. Since ubiquitous computing capability may take the form of advanced personal digitized assistants (PDAs), wearable computer systems featuring heads up displays, or argumented reality systems, this proposal addresses key issues which include: (1) personal environment data capture, (2) environmental data salience, (3) transport of multimedia data over wireless and heterogeneous network systems in a client-server environment, (4) media access and retrieval, and (5) human-computer-interface (HCI) design and analysis. Some of the significant questions that are addressed in the project are: (a) given continuous audio and video capture, what is the best choice of content to archive in a personal multimedia database? (b) how can audio and video capture of unconstrained content be used as an effective query mechanism for a multimedia database? (c) how can perceived latency and communications performance be optimized in a wireless environment where bandwidth, error rates, and latency are continuously variable and dependent upon many environmental conditions?, (d) how can the quality-of-service for the transport of real-time multimedia traffic be guaranteed using heterogeneous networks and wireless network systems?, and (e) what should be the design principles to support a fully mobile user engaged in hand-free high-bandwidth, collaborative work and communication? New algorithms and techniques will be developed and tested to address these questions either via simulation, emulation, or experimentation. It is anticipated that the existing facilities will be significantly enhanced via a pending NSF research equipment proposal. This proposed equipment (e.g., VoD servers, multimedia lap tops, WaveLan products, wearable argumented reality interfaces) will be the defining infrastructure to support a sophisticated testbed, connecting three research laboratories (HSNP, MET, MIND) via wireless links. The multi-lab testbed will be used for the experimental phase of the project. As an effort to broaden the participation in our research, the PIs will invite interested faculty (via two-week summer workshops) and students (via ten-week summer research experience) from HBCUs (Historically Black Colleges and Universities) to work with them during the three summers. Additionally, the PIs will invite a few interested professionals from industry to participate in the research initiatives.
