CAREER: Fostering Scoped Multi-Device Interaction In Ubiquitous Computing Environments

无处不在的计算提供了一个从根本上更具响应性的物理环境的愿景，在这个环境中，用户从与无处不在的互联世界中的无数无线和有线设备，例如无线个人数字助理、支持视频的移动电话、可穿戴计算机、家用电器、售货亭、玩具和传感器的无缝交互中受益。普适计算开发基础设施的一个关键组成部分是基于服务的发现和广告。在典型的无所不在的计算场景中，走进房间的用户能够与房间中的设备提供的各种服务进行交互。服务发现框架的目标是帮助用户的应用程序确定此房间中哪些服务可用于交互。虽然当前的服务发现框架是普适计算基础设施的基本初始组件，但还需要其他功能来应对多设备多用户环境带来的挑战。这个职业计划的目标是探索在无处不在的计算环境中促进范围内的多设备交互的方法。在该提案中，几个关键研究领域被确定为实现多设备多用户泛在计算必须解决的具有挑战性的问题：多设备之间的主动设备解析，特别强调多用户之间的社交上下文主动用户解析，其中特别强调社交上下文组成远程控制之外的联合广域和局部多设备元服务：使能新的泛在计算应用。本提案的目的是首先了解多设备多用户上下文的含义和要求，然后设计和开发移动计算应用、分布式中间件系统、元服务、以及无线和应用层网络协议，这些协议将有助于实现多设备普适计算的愿景。最初的目标是在部门智能空间实验室中构建普适计算所需的基础设施。一门关于普适计算的课程将允许学生在智能空间实验室的基础设施建设部分实践中做出贡献，即使课程进行了升级，以反映最近的研究创新。该基础设施最终将能够支持远程控制应用、无线对等应用和事件通知应用，仅举几例。一旦研究实验室技术成熟，目标是在整个大学校园内部署该基础设施。这对整个大学的影响将是非常有益的，因为最成熟的技术应该立即在整个校园内可用。一旦事件通知、无线消息传递和远程控制基础设施就位，学生、教授和公民应该能够立即从我们无处不在的计算研究成果中受益。整个校园的部署预计将在这个五年计划的一半左右开始。

Ubiquitous computing offers the vision of a fundamentally more responsive physical environment in which users benefit from seamless interaction with a pervasively internetworked world of myriad wireless and wired devices, e.g. wireless personal digital assistants, video-enabled mobile phones, wearable computers, appliances, kiosks, toys, and sensors. A key component of the developing infrastructure for ubiquitous computing is based on the discovery and advertisement of services. In a typical ubiquitous computing scenario, a user who walks into a room is able to interact with a variety of services offered by the devices in the room. The goal of the service discovery framework is to assist the user's application in determining what services are available for interaction in this room.While the current service discovery framework represents an essential initial component of the ubiquitous computing infrastructure, additional capabilities are needed to address the challenges introduced by multidevice multi-user contexts. The objectives of this CAREER proposal are to explore the means for fostering scoped multi-device interaction in ubiquitous computing environments. Several key research areas are identified in this proposal as challenging problems that must be solved in order to enable multidevice multi-user ubiquitous computing: Active device resolution among multiple devices, with special emphasis on social context Active user resolution among multiple users, with special emphasis on social context Composing joint wide-area and local-area multi-device meta-services Beyond remote control: enabling new classes of ubiquitous computing applicationsThe intent of this proposal is to first understand the implications and requirements of multi-device multiuser contexts, and to then design and develop the mobile computing applications, distributed middleware systems, meta-services, and wireless and application-level networking protocols that will assist in making the vision of multi-device ubiquitous computing a reality.The initial goal is to build the infrastructure necessary for ubiquitous computing in a departmental Smart Spaces Lab. A course taught on ubiquitous computing will allow students to make hands-oncontributions to building portions of the infrastructure in the Smart Spaces Lab, even as the curricula is upgraded to reflect recent research innovations. The infrastructure will eventually be able to support remote control applications, wireless peer-to-peer applications, and event-notification applications, just to name a few. Once the research lab technology matures, the goal is to deploy this infrastructure throughout the university campus. The impact on the university at large will be highly beneficial, as the most mature technology should be immediately available throughout campus. As soon as the event notification, wireless message passing and remote-control infrastructures are in place, students, professors, and citizens should be able to immediately benefit from the fruits of our ubiquitous computing research. Campus-wide deployment is expected to begin about halfway through this five year research plan.
