Terveen, Loren Konstan, Joseph A. Riedl, JohnShekhar， Shashi University of Minnesota Twin Cities标题：CISE RR: Being There：这个项目建立了一个移动计算系统，提供了一套移动的、连接的、位置感知的计算单元，由个人数字助理（pda）和可穿戴显示器组成，具有一定的输入能力，允许实验影响接口类型、应用程序和技术的部署，因为这些设备变得司空见惯。设备将进行广泛的实验，从严格控制的实验到广泛的实地研究，从先前计划的现有研究的扩展到学生项目的最后一刻的想法，从小型试点研究到大型部署研究。该基础设施支持人机交互（HCI）、推荐系统和用户移动环境的空间数据管理方面的研究项目；具体来说，无处不在的周边社会互动（UPSI），位置感知推荐系统，以及位置感知移动计算的空间数据管理。第一个项目假定有几个无线通信信道可用。处于用户注意力边缘的信息不断地流到设备上，并以滚动的“行情”显示。用户携带一台袖珍电脑，佩戴一个通过蓝牙连接的联网手腕设备。这种方法在填充和管理驱动交互的信息模型、为联网手腕显示器设计接口、耦合手腕计算机和PDA以及确定适合这种交互范例的任务类型方面提出了挑战。第二个项目通过算法和界面研究、试点测试、真实世界实验和指标，在有线、非连接和无线连接的推荐系统中寻找合适的应用。考虑到用户的本地和时间模式，本项目将研究何时适合用推荐打断其用户，如何跨多设备界面最有效地呈现推荐，以及如何在用户与网络断开连接时计算推荐。最后一个项目研究了基于移动位置的推荐系统等应用对空间数据管理系统的需求。该项目从位置感知推荐系统收集基于跟踪的工作负载，以评估关键设计决策的解决方案，如地图压缩算法和基于过去空间查询、预定会议地点和相关信息缓存地图相关片段的预测性预取策略。该教育计划包括将该平台整合到课程中，并让学生参与暑期实习。

EIA 0224392 Terveen, Loren Konstan, Joseph A. Riedl, JohnShekhar, Shashi University of Minnesota Twin Cities Title: CISE RR: Being There: Mobile Devices for Community and Commerce This project, building a mobile computing system, provides a set of mobile, connected, location-aware computing units consisting of Personal Digital Assistants (PDAs) and wearable displays with some input ability to allow experimentation to affect deployment on the types of interfaces, applications, and technologies needed as these devices become commonplace. Devices will carry out a wide range of experimentation, from tightly controlled experiments to broad field studies, from previously planned extensions of existing research to last-minute ideas created by student projects, and from small pilot studies to large deployment studies. The infrastructure supports research projects in human computer interaction (HCI), recommender systems, and spatial data management for environments where users are mobile; specifically, Ubiquitous Peripheral Social Interaction (UPSI), Location-Aware Recommender Systems, andSpatial Data Management for Location Aware Mobile Computing.The first project presumes availability of several wireless communication channels. Information, at the periphery of users' attention, is constantly streamed to the device and displayed as a scrolling "ticker." A user carries a pocket computer and wears a Networked Wrist Device linked by Bluetooth. This approach presents challenges in populating and managing the information model driving the interaction, designing the interface for the networked wrist display, coupling the wrist computer and PDA, and identifying the types of tasks for which this interaction paradigm is suitable. Using algorithmic and interface research, pilot tests, real-world experiments, and metrics, the second project looks into suitable applications among wired, disconnected, and wireless connected recommenders. Given local and temporal patterns of users, this project examines when it is appropriate to interrupt its user with a recommendation, how to present recommendations most effectively across multi-device interfaces, and how to compute recommendations when the user is disconnected from the network. The last project looks into the requirements of spatial data management systems for applications like mobile location based recommendation systems. The project gathers a trace-based workload from location aware recommendation systems to evaluate solutions for critical design decisions such as algorithms for map compression and predictive pre-fetching strategies to cache relevant segments of maps based on past spatial queries, scheduled meetings locations, and related information. The educational plan includes integration of the platform into courses and student involvement in summer internships.
