This project develops a high-level notion of context that exploits the capabilities of next generation networks to enable applications that deliver better user experiences. In particular, it exploits mobile devices -- always with a user -- to capture key elements of context: the user's location and, through localization, characteristics of the user's environment. What matters for the user experience is the user's place: a location in conceptual terms such as "at home," "jogging," or "grocery shopping" -- descriptions that combine positions with activities, environmental properties, and the activities of other nearby people. Realizing this notion of place requires that information from devices and infrastructure flow in ways unanticipated in current network architectures. It presumes enabling opportunistic interactions while preserving the users' privacy and designing incentive mechanisms to promote cooperation without exploitation of any. The above architectural concerns lie far beyond traditional network topics such as routing.This project will develop, demonstrate, and evaluate a novel network architecture that gives primacy to user experience. It will lead to theoretical advances in semantic context modeling, mobility tracking at multiple levels of abstraction, collaborative localization, and incentive mechanisms. Networked applications offering enhanced user experience will have significant payoffs for industry and the productivity and quality of life of citizens. A prototype system will implement and evaluate context-aware services in university settings with prospects of expansion to K-12 schools and public facilities.

该项目开发了一种高级上下文概念，利用下一代网络的功能来支持应用程序提供更好的用户体验。特别是，它利用移动设备（始终与用户一起）来捕获上下文的关键元素：用户的位置，以及通过本地化获取用户环境的特征。对于用户体验而言，重要的是用户所在的位置：概念术语中的位置，例如“在家”、“慢跑”或“杂货购物”——将位置与活动、环境属性以及附近其他人的活动相结合的描述人们。实现这种位置概念需要来自设备和基础设施的信息以当前网络架构中无法预料的方式流动。它假定在​​保护用户隐私的同时实现机会主义互动，并设计激励机制来促进合作而不利用任何隐私。上述架构问题远远超出了路由等传统网络主题。该项目将开发、演示和评估一种新颖的网络架构，该架构将用户体验放在首位。它将带来语义上下文建模、多个抽象级别的移动跟踪、协作定位和激励机制方面的理论进步。提供增强的用户体验的网络应用程序将为工业以及公民的生产力和生活质量带来巨大的回报。原型系统将在大学环境中实施和评估情境感知服务，并有望扩展到 K-12 学校和公共设施。
