Activity-Oriented Pervasive Computing

这个项目正在开发科学和工程基础，以实现对以用户为中心的活动的自动化支持，其中使用对用户基本上透明的计算基础设施来增强用户执行日常任务的能力。该项目专注于家庭环境等非计算机中心环境，建立在任务驱动计算概念的基础上，以设计、实现和评估一个通用平台，在该平台上可以轻松地构建和集成许多基于活动的应用程序。具体地说，它正在创造新的原则、算法和设计框架，以实现新兴普适计算设备和服务的灵活集成、适应和配置；新技术，用于确保在不可预测的环境中不同的、动态变化的普适服务配置的健壮性；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人类活动，而不是要求人类将其需求映射到以计算机为中心的应用程序。这项研究可能产生三个重大的广泛影响。(1)它将扩大综合计算机支持的范围，以便在计算支持尚未广泛获得的环境中(例如在家里)，对严重影响非计算机用户的活动提供支持；(2)它将有助于缩小普通用户从计算系统改善其日常生活所需要的东西与目前以计算机为中心的技术所提供的东西之间的差距；(3)它将降低部署和使用新兴普及计算技术的复杂性，同时提高其可预测性和稳健性。

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.
