Activity-Oriented Pervasive Computing

AbstractThis project is developing the scientific and engineering foundations to enable automated support of user-centered activities where a computing infrastructure，which is greatly transparent to the user，is used to enhance a user ability to carry out everyday tasks.专注于非计算机为中心的环境，如家庭环境，该项目建立在任务驱动计算的概念，设计，实施和评估一个通用平台上，许多基于活动的应用程序可以很容易地建立和集成。具体而言，它正在创建新的原则、算法和设计框架，以使新兴的普及计算设备和服务能够灵活地集成、适应和配置;新的技术，以确保在不可预测的环境中普及服务的异构、动态变化的配置的鲁棒性;以及思考和实现系统的新方法，在这些系统中，计算增强和补充了普通的人类活动，而不是要求人类将他们的需求映射到以计算机为中心的应用程序中。这项研究有可能产生三个重大的广泛影响。(1)它将扩大综合计算机支助的范围，以帮助那些在计算机支助尚未得到广泛利用的环境中对非计算机用户产生重大影响的活动（2）它将有助于减少普通用户需要从计算系统中得到什么来改善他们的日常生活与当前以计算机为中心的技术现在提供什么之间的差距;（3）它将降低部署和使用新兴普适计算技术的复杂性，同时提高其可预测性和鲁棒性。

AbstractThis project is developing the scientific and engineering foundations to enable automated support of user-centered activities where a computing infrastructure, which is largely transparent to the user, is used to enhance a users ability to carry out every-day tasks. Focusing on non-computer centric environments such as home environments, the project builds on the notion of task-driven computing to design, implement, and evaluate a general platform on which many activity-based applications can be easily built and integrated. Specifically, it is creating new principles, algorithms, and design frameworks to enable flexible integration, adaptation and configuration of emerging pervasive computing devices and services; new techniques for ensuring the robustness of heterogeneous, dynamically-changing configurations of pervasive services in unpredictable environments; and new ways to think about and implement systems in which computing augments and complements ordinary human activities, rather than requiring humans to map their needs into computer-centric applications.This research has the potential for three significant broad impacts. (1) It will extend the reach of integrated computer support for activities that critically affect non-computer users in environments where computing support has not been broadly accessible (such as in the home); (2) It will help decrease the gap between what ordinary users need from computing systems to improve their daily lives, and what is now provided by current computer-centric technology; (3) It will reduce the complexity of deploying and using emerging pervasive computing technology, while at the same time improving its predictability and robustness.
