It is not well understood how services such as group SMS, SMS-based discussion lists and mobile instant messaging (IM) will be used by mobile groups in natural settings. Studying specific instances of common styles of in situ, group interaction may provide a way to see behavior patterns and typical interaction problems. We conducted a study of a mobile, group communication probe used during a rendezvousing activity in an urban environment. Usability problems relating to group usage, phone interface design and context were identified. Several major issues included: multitasking during message composition and reading; speed of text entry; excessive demand on visual attention; and ambiguity of intended recipients. We suggest that existing mobile device designs are overly-focused on individual users to the detriment of usability for mobile groups of users. We provide recommendations for the design of future mobile, group interfaces, used in similar situations to those explored here","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126647198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ward","doi":"10.1109/ISCST.2005.1553286","DOIUrl":"https://doi.org/10.1109/ISCST.2005.1553286","url":null,"abstract":"Summary form only given. Recent research and development by Ball Aerospace's Collaborative Technologies and Solution Group (CTSG) have underscored the need of a new genre of collaboration and communication technology. Ball is developing a new desktop collaboration tool called net-centric operations or simply \"NetOps.\" NetOps is a cross-platform, companion-tool to KnowledgeKinetics, which aims to fill a void found in current COTS human collaboration tools. NetOps is a desktop-based (thick client) presence and instant messenger application providing an extendable set of tools and capabilities, which promote team collaboration and coordination on a large scale. NetOps communicates presence and chat information using the Jabber XML-based XMPP standard, while Web-services handle tool or organizational information to make communications through firewalls a non-issue. In addition, NetOps provides the capability of domain specific inter/intra crew tasking, communications, alerting, and presence management in a 24/7 operating environment. Ball's integrated virtual meeting application (VMA) tool allows users to schedule virtual meetings, conduct video teleconferences, and execute instant meetings. Both NetOps and VMA provide open plug-in architectures and APIs other developers may use to extend the base capabilities or add domain specific tools. At CTS 2005, we provide an interactive demonstration of the current state of the NetOps technologies and tools. Demonstration attendees are able to connect to a NetOps server wirelessly and/or via Ethernet, automatically download the NetOps client, and participate in the demo. An interactive demonstration of VMA, including video teleconferencing using wavelet compression over HTTP/S, is also presented","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115353680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identity is generally at the heart of most conflicts, and identity oth individual and collective - is rooted in culture. Understanding and appreciation of the cultural identity of the parties to an emerging conflict is critical to both understanding and transforming that conflict. Unfortunately, the cultural nuances of many conflicts are overlooked when standard Western models of conflict resolution are applied. This paper describes recent research in this area conducted for the National Intelligence Community. This work was extended for use by the Nobel Appeal Foundation and applied in several real-world peacemaking situations. That work is now being extended to identify cultural \"indicators and warnings\" to activities or proposed activities within the peacekeeping process under a new effort funded by the Defense Advance Research Projects Agency (DARPA). This environment provides a mechanism for the automatic ingestion of status information and news into a machine understandable \"situation context\". A community of agents does partial matching of the known situation context to two semantically linked classes of models within the system: mission-independent cultural models; and culturally-independent mission models.

This testbed initially support the capture and modeling of existing C2 processes/subprocesses. Having modeled these at proper levels of abstraction, proposed revisions or replacements to processes, systems, and subsystems can be evaluated within a virtual workspace that integrates human operators and automated systems in the context of a larger C2 process. By utilizing such a testbed early in the development cycle, expected improvements resulting from specific revisions or replacements can be quantitatively established. Crossover effects resulting from changes to one or more interrelated processes can also be measured. Quantified measures of improvement can then be provided to decision makers for use in cost-to-performance benefits analysis prior to implementing proposed revisions or replacements or a sequence of planned enhancements.

The National Science Foundation (NSF) established an Industry/University Cooperative Research Center (I/UCRC) for e-Design at the University of Pittsburgh, the University of Massachusetts Amherst, and the University of Central Florida. The center serves as a national center of excellence in information technology (IT)-enabled design and realization of discrete manufactured products. It is currently supported by a growing number of US industry partners and US government agencies including GEAE, Ford Motor Co., Alcoa, Pratt & Whitney, Lockheed Martin, PTC, ANSYS, Raytheon, Respironics, BAE Systems, IBM, Engineous Software, VirtualE3D, and the federal agencies, including DoD, NIST, and NASA. Two additional universities, Carnegie Mellon University and Virginia Tech, join the center. Through four research thrusts, (1) enabling information infrastructure, (2) life-cycle, collaborative, and multidisciplinary design, (3) conceptual design tools and design process models, and (4) virtual prototyping and simulation, more than 30 faculty members along with their graduate students are conducting research activities to realize the innovative e-design paradigm. This demonstration presents the Pegasus gateway that enables a collaborative service-oriented design paradigm with capability for interoperability, trust-support infrastructure, systems engineering approach to design, integrated product realization through optimization, transparency, conflict resolution & negotiation, pro-activeness of analysis, virtual simulation & prototyping, lean product data management, multidisciplinary constraints & preferences capturing, and instant distributed access & visualization. As a case scenario, this demonstration shows how the Pegasus gateway can be efficiently employed in collaboration for assembly design. The Pegasus gateway and service-oriented collaboration architecture realizes an environment in which joining knowledge is captured early in the assembly design process and is propagated seamlessly and transparently to downstream activities including virtual assembly analysis and assembly design decision-making","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131319455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scientific annotation middleware (SAM) project, a Department of Energy (DOE)-funded effort at Pacific Northwest and Oak Ridge National Laboratories, envisions a new model in which ENs are simply one application contributing to a much richer and semantically explicit record. Such a record would include, for example, data provenance, descriptive metadata, and annotations from a wide range of applications, problem solving environments, and agents.
