HCC: Small: Activity-Enriched Computing

尽管网络和不断扩大的网络连接带来了无数非凡的好处，但计算机几乎与生活的方方面面交织在一起，也带来了越来越多的干扰。这些干扰和由此产生的活动的碎片化日益成为现代生活的一部分。以人为中心的计算的一个关键的研究挑战是如何平滑和减轻中断的影响，以及协助恢复被中断的活动。为了应对这一挑战，需要超越传统的以文档为中心的信息视图，以解决实际活动的复杂性，其往往是碎片化的历史，以及访问数字和纸质媒体上排列的信息的需求。该项目将探索系统的设计，使人们能够利用视觉和情景记忆，从计算机媒介活动的历史和背景中获益。该项目的核心是重新思考存储在计算机中的数据的本质，从一种状态转变为可以呈现给用户的可检查的交互活动历史。活动丰富的计算有可能重塑我们使用计算机的方式，通过创建对过去事件的历史作出反应并被其增强的系统，改变计算机环境，使其在需要时始终可以获得历史的帮助。主要的科学贡献将是：(a)开发一个活动丰富的计算框架，用于设计一类新的系统，其中历史是一级元素；(b)原型化和评估活动丰富的应用程序；(c)扩展用于表示、可视化和分析活动历史的理论和方法。科学贡献将包括一个新颖的活动丰富的计算框架，该框架将(a)捕获计算机介导的活动的丰富细节，(b)识别并提供有意义和有用的事件，(c)连接纸质和数字文档的世界，以及(d)利用摘要和视觉访问机制来支持活动历史的导航，并简化中断活动的恢复。总体目标是减少中断的影响，并帮助重建环境。更广泛的影响：提议的活动的更广泛的影响包括从根本上提高所有计算机媒介活动的功效的潜力。项目的成果和开发的软件将广泛传播，并在项目网站上提供。额外的影响将来自培养学生设计活动丰富的计算应用所需的跨学科方法，为研究生和本科生提供研究机会。一个长期的影响将是使一个研究社区具体化，以进一步发展和发展活动丰富的计算。

Although myriad extraordinary benefits have resulted from the web and expanding network connectivity, the intertwining of computers with virtually every aspect of life also brings a growing stream of interruptions. These interruptions and the fragmenting of activity they produce are increasingly accepted parts of modern life. A critical research challenge for human-centered computing is how to smooth and mitigate the impact of interruptions as well as assist in resuming interrupted activities. Meeting this challenge will require moving beyond the traditional document-centric view of information to address the complexity of real activity, its often fragmented history, and the need to access information arrayed across digital and paper media.This project will explore the design of systems that will allow people to exploit visual and episodic memory to benefit from the capture of the history and context of their computer-mediated activities. The heart of the project is rethinking the nature of data as stored in computers from being a state to being an inspectable activity history of interaction that can be presented to users. Activity-enriched computing has the potential to reshape how we use computers by creating systems that react to and are augmented by the history of past events, changing the computer environment to one in which history is always available to assist if needed. The primary scientific contributions will be to (a) develop an activity-enriched computing framework for designing a new class of systems in which history is a first-class element, (b) prototype and evaluate activity-enriched applications, and (c) extend theory and methods for representing, visualizing, and analyzing activity histories. Scientific contributions will include a novel activity-enriched computing framework that will (a) capture the rich detail of computer-mediated activity, (b) identify and make meaningful and useful episodes available, (c) link the worlds of paper and digital documents, and (d) exploit summarization and visual access mechanisms to support navigation of activity histories and ease resuming interrupted activities. The overarching objective is to lessen the impact of interruptions and aid reestablishment of context.Broader Impacts: The broader impacts of the proposed activity include the potential to radically improve the efficacy of all computer-mediated activities. The results of the project and the software developed will be widely disseminated and made available on the project website. Additional impact will result from training students in the interdisciplinary approach required to design activity-enriched computing applications, providing research opportunities for both graduate and undergraduate students. A long-term impact will be to crystallize a research community to further develop and evolve activity-enriched computing.
