RESEARCH: ========= My current research topic can be summerized as "context aware infrastructures for mobile services". My former research and implementation of a service infrastructure for mobile devices including WAP phones showed that taking context into account can have extremely positive impact on service platforms for mobile devices. Currently only the use of context in applications for mobile users is considered to be important. These kind of applications normally deliver better results to users. But even more important in my opinion is that context can and must be used for service discovery and service orchestration. In near future there will be many services using each other to perform tasks for users. The gathering and combining of these services ("service orchestration") itself is a dynamic process influenced by the context of the services' users. E.G. today calendars like Outlook inform users at a fixed time before the meeting. If the calendar knew the location of the user it could calculate the time before it must remind the user. Calculation can be done by asking other services like timetable for public transport or route planner for car. Finding these services of course depends on the users' context. CV: === Gerhard Austaller was born in Eberstalzell (Austria) in 1973. He received the degree of "Diplom-Ingenieur" (Dipl.-Ing.) in Computer Sciense at the Johannes Kepler University Linz in fall 1999. In his master thesis he explored possibilities to overcome some problems in mobile computing environments notably disconnections. Afterwards he there joined the Telecooperation Group as research assistant with focus on service-based infrastructures. In spring 2001 he moved to the Telecooperation Group at the Darmstadt University of Technologie. There he is researching on bringing the advantages of context-aware computing to mobile services and infrastructures. PUBLICATIONS: ============= Andreas Hartl, Gerhard Austaller, G. Kappel, C.

I am a research assistant in the Distributed Systems Group headed by Prof. Rothermel at the University of Stuttgart. I am working on the Nexus project, a project funded by the German Research Foundation (DFG) with partners from the areas of photogrammetry, electrical engineering, databases, visualization and distributed systems. We investigate concepts and methods for the support of context-aware applications for mobile users, where the most important context information is location. The goal is to develop a global platform for context-aware applications with a federated, distributed and dynamic model of the real world at its core that is augmented with virtual information. My area of research within the project is the efficient observation of spatial events, i.e. events that are related to the position of mobile objects in space. A typical example for such an event is that a user wants to be informed when passing a shoe shop, because he needs to buy shoes (and usually forgets about it when he is in town). The information that is necessary for observing such an event may be distributed among different servers and therefore the observation of the event may also be distributed. This means that time concepts have to be taken into account in order to have a well-defined semantics for the distributed event, which can be described using an event specification language, e.g. based on global predicates. The observation of events then has to be distributed to observation nodes in an optimal way regarding parameters like delay (affecting the semantics) and communication overhead. The summer school covers issues (e.g. location-awareness, context-awareness, mobile computing, middleware computing infrastructures, security and privacy) that are very relevant for the Nexus research project as a whole as well as for my own research, with lecturers who are well-known in these fields. I hope to exchange ideas about the current research topics in this field with the participants of the workshop, which may be the basis for future cooperations. I would like to contribute to the workshop, especially on topics concerning location-awareness and the distributed observation of events.

I have just completed my PhD in Electrical Engineering with a thesis on Collaborative Augmented Reality. I am interested in getting a good grounding in ubiquitous and pervasive computing for research work that I intend doing in the future. In addition to gaining a good overview of current research in the field I'm hoping to use the workshop as an opportunity to network with researchers with similar interests and to establish some research collaborations. I am particularly interested in how ubiquitous computing technology could be used to support face to face and remote collaboration. I think that this is an important research area that has needs further work. Although I have not begun work in the area yet, I will do so later this year. In particular I am interested in how people can use handeld (PDA) devices to interact with smart spaces to support collaboration. This enables users to have a private handheld display as well as a public display space that they can move data between. Interaction and display techniques for this type of interface and the effect that this might have on the collaboration are areas of interest.

My main research interest (i.e., my Ph.D. thesis topic) is on cooperation of nodes for routing and forwarding in mobile ad-hoc networks, where nodes do not rely on any routing infrastructure but relay packets for each other. Thus communications in mobile ad-hoc networks work properly only if the participating nodes cooperate in routing and forwarding. However, it may be advantageous for individual nodes not to cooperate, for example to save power or to launch security attacks such as denial-of-service. I developed a protocol, called CONFIDANT, to mitigate the effect of such misbehavior, it aims at detecting and isolating misbehaving nodes, thus making it unattractive to deny cooperation. Trust relationships and routing decisions are based on experienced, observed, or reported routing and forwarding behavior of other nodes. For some details see our paper at MobiHOC 2002. I am interested in game-theoretic and Bayesian approaches to evaluate and improve cooperation among network nodes. Other research interests include peer-to-peer networks, network security, sensor networks, and overlay networks. Background: Since February 2000 I have been an off-site Ph.D. student at EPFL Lausanne, Communications Systems. My advisor is Prof. Jean-Yves Le Boudec. I have been working at the IBM Zurich Research Laboratory, Networking Software Group, since April 1999. Our current project is on network appliances for massively distributed applications, e.g., games.

I own a joint master's degree in Business Administration and Computer Engineering from the Technical University of Darmstadt. I specialized in distributed multimedia systems and internet technology. My main educators were Ralf Steinmetz from the Technical University of Darmstadt, for whom I worked for about a year as assistant staff, and Klara Nahrstedt at the University of Illinois at Urbana-Champaign, where I spent a year in her research group working on adaptive mechanisms for MPEG-2 streaming in a live- and potentially wireless scenario. Since 1st of March this year, I am a PhD student at the Department of Communication Systems and Computer Networks at the LMU Munich (Prof. Hegering & Prof. Linnhoff-Popien). I am currently engaged in a research endeavour trying to scale existing smart space test-beds to a country-wide scope. This project is named "context-aware services for UMTS". Our partners are Siemens Corporate Technology and Apollis Interactive, a start-up company that was the first to offer a location-based service in Germany. The project is financed by the State of Bavaria. The focus of our work is to develop a framework for the provision of context information in cellular networks and to prove our concepts by implementing prototypes. The framework is necessary to decouple the provisioning of context from its usage, thereby allowing for a new business role called context provider.

Jochen Denzinger holds a master in industrial design and is currently working for the MARS Exploratory Media Lab/ Fraunhofer Gesellschaft. He is mainly concerned with questions in the domain of information architecture, interaction- and interfacedesign. From 1997 till 2000 JD worked as a freelance software designer. One of his main projects was his work for the IPSI (Institut für Integrierte Publikations- und Informationssysteme) of the former GMD in Darmstadt in the team of Norbert Streitz on topics as cscw and augmented reality. (http://www.ipsi.fraunhofer.de/ambiente) Until march 2002 he worked as a researcher at Hochschule für Gestaltung Offenbach am Main (Dpt. Industrial Design). Currently JD is writing on his phd-thesis on the subject of design and ubiquitous computing at Prof. Mihai Nadin (Universität Wuppertal/ Dpt. Computational Design). Looking from a designer's perspective the work examines the question of the mutual influences of ubiquitous computing on the discipline of design and the possible roles of design in ubicomp. For his thesis JD provides a website: http://www.designing-ubicomp.com (currently only German) ___ I am interested in the "Summer School on Ubiquitous and Pervasive Computing" as it seems a quite unique opportunity to get an overview and insight on my phd's topic from different perspectives. I expect to broaden my view due to interpersonal communications. I would like to contribute to the workshop talking on ubicomp under a design perspective. JD

1. Background: Studied electrical engineering (topics: systems theory, pattern classification). Currently PhD student. 2. Research field: location and context awareness, location technology based on ultrasound. (See summary below) 3. Expecting from the summerschool: Meet people who work on all types of location systems and models! Also educate myself more broadly in the UbiComp field. 4. Presentation topic: ultrasound positioning technology. Research summary: Many Context Aware applications need information on the location of people, objects and devices. Sometimes orientation or movement information is desired as well. We focus on future consumer applications in the home domain. This domain has a unique combination of requirements: 1. Low-cost, high-volume electronics ; 2. Low power ; 3. Resolution required varies from 1 cm to several meters ; 4. Easy installation by a non-expert user. A survey of state-of-the-art technology showed that none of the existing systems could handle all requirements simultaneously. Ultrasound location technology turned out to be a promising candidate for accurate indoor location systems. Therefore we work on new ultrasound-based measurement methods and algorithms, that are needed to realise an in-home 'plug and play' location system. Topics include: System modelling, optimizing the configuration of transmitters/receivers, and orientation estimation.

After studying Computer Science at the University of Trier (Germany), since November 2001 I am working on my PhD thesis. I am employed as a scientific assistant at the research group for System Software and Distributed Systems at the University of Trier. I participate in the SOUL project (self organized ubiquitous learning), which is funded by DFG, Schwerpunktprogramm SPP1140 "Basissoftware für selbstorganisierende Infrastrukturen für vernetzte mobile Systeme". This project covers the design of middleware components for networked mobile systems and their experimental validation in the scope of self organizing university exercises. Currently we are working on the design of a novel communication pattern for mobile ad-hoc networks based on a market place metaphor. A marketplace is a fixed geographical location where information is traded at given times. Client requests or agents acting on behalf of the client travel to the marketplace by infecting promising nearby devices. When arriving at the marketplace, the device actually hosing the request or agent is searching for matching peers by periodically announcing the set of requirements. At a given deadline or if a sufficient number of matching peers is found, the response resp. the successful agent will travel back to the home coordinates of the initiator. A paper with the protocol description and simulation results has been submitted to KIVS 2003 (Kommunikation in Verteilten Systemen 2003).

My work is focused on context aware computing for wearable computers. It is being conducted as part of the wearable computing initiative at ETH Zurich. Our vision of a wearable computer is that of an assistant, that is always on and trying to support the user in his everyday tasks. Since the computer is permanently worn by the user, it can perceive the environment in the same way the user can, "see" what the users, "hear" what the user hears, etc. My work is hence focused on extracting contextual information from multiple sensors in a wearable computer. This includes context modeling, multi-sensor perception and fusion. My expectation of the summer school is to get in touch with the most recent developments in wearable and ubiquitous computing and the people behind it!

I have received a MSc degree in Computer Science in 1992 and in Physics in 1993 and a Ph.D in 1999 all from the University of Karlsruhe in Germany. Since 1999 I am postdoctoral researcher in charge of the Wearable Computing Lab and the Computer Architecture Group at the Department of Information Technology and Electrical Engineering of the ETH Zurich. In my research I concentrate on architectural and system design issues in wearable computing as well as on multisensor systems for context recognition. I have been in charge of the development of the WearARM wearable system build in our lab. Currently my focus is on modeling and evaluating different variants of heterogenous, distributed wearable architectures with respect to their performance and power consumption for different applications. An important part of such architectures are distributed sensor units that can be used to derive complex information about the user's context and activity from simple signals. I would like to contribute to the workshop by presenting the architecture concept, model and implementation of our wearable computing and sensing system. This could be a good starting point for discussion with other participants about the system requirements of different wearable and ubiquitous applications. I am particularly interested in the types of context information that people would find useful for their applications.

I work as a researcher at the Swedish Institute of Computer Science, and I am a PhD student at the department of information technology at Uppsala university. I have a Master degree in Computational Linguistics. My research focus is human-computer interaction and device independent mobile services. I work with finding ways to develop services that are cross platform and that can adapt to the different devices or platforms that they running on or are accessed from. Computing devices of today are very different in their capability of presenting information, accept input and many other areas that highly affect the users experience. This means that services will have to adapt their user interface and functionality to be able to present good user interaction.

I'm a first year Ph.D. student, at the Maersk Institute at University of Southern Denmark, working on framework development for the TangO conceptual model. TangO is a conceptual model for pervasive computing, where we try to model the pervasive world in terms of habitats, tangible objects, and associations. The concepts are related to physical, logical, and informational spaces. Currently I'm working on Jini as a technological platform for the framework, and I am trying to implement simple pervasive systems to justify the power of the Jini technology. I hope the summer school will widen my view of pervasive and ubiquitous computing. The topics for the school seem very interesting, and they are all topics I have given some thoughts during my research project. For the talk, I would like to talk a little about the TangO conceptual model in terms of Jini, and properly demonstrate, some of the applications.

I’m a researcher atHP Labs Grenoble since October 2000: http://www.hpl.hp.com/grenoble/index.html I have an engineer diploma from Supelec where I have followed a specialization on network systems: http://www.supelec.fr My research topic addresses the problem of user personal information distribution on user devices. This implies a large amount of challenges such as: - How to provide data availability while keeping data consistent? - What is trustworthy user storage? - How should we deal with lightweight devices considering their limitations (bandwidth, storage resource, battery limitations…) regarding the storage of user information? - How to provide a user-friendly storage solution? All the mechanisms put in place to respond to previous challenges must not spoil the user experience but facilitate his interaction with the virtual world. Aside my research focus, I’m interested in the impact of new technologies on people and how people interact with these technologies in their daily life. From this workshop I expect to confront my ideas of how to tackle such problems, consolidate my vision of the next distributed computing generation and get contacts with other people working in the field.

I studied computer science at the Darmstadt University of Technology and at the University of Colorado at Boulder. Since May 2000 I have been working as a research assistant and PhD student in the Distributed Systems Group at the Swiss Federal Institute of Technology (ETH Zurich). I am interested in distributed systems, ubiquitous computing, and ubiquitous user interfaces, in particular in the integration of computational capabilities into everyday objects and physical environments and their presentation to users. This includes the development of flexible infrastructures that support dynamic networking of tiny computing components and techniques for coupling physical everyday objects with computational functionality. Another area of interest is security using smart cards. Currently, I am involved in the ETH World project - an initiative to establish a virtual campus augmenting the physical infrastructure of ETH Zurich. We conduct a subproject called "Entry Points into the ETH World Infostructure" [1]. Its main objectives are the interweaving of the infostructure of ETH World with the physical infrastructure of ETH; the provision and utilization of location information; and the investigation and evaluation of privacy and user acceptance aspects. Past projects include the CASTING project [2], done jointly with Swisscom AG Bern, Corporate Technology, in which we explored ways to use mobile phones as remote card readers to authenticate users and to secure applications. The topic of my diploma thesis was the integration of smart cards in Jini federations. The result is an architecture that defines a standard way to access smart cards remotely, explore the services they contain, and make them available as Jini services. More information can be found on the JiniCard Homepage [3].

My research concentrates on the augmentation of every day objects with sensing, computing and communication capabilities. The goal is to enhance the user's interaction with his environment. I am especially interested on relationships between objects and the exploration what kind of functionality emerges by the dynamic change of these relationships. This research is closely connected to the Smart-Its project (http://www.smart-its.org).

Biography Andreas Weissel studied computer science at the University of Erlangen and became a research staff member of the Distributed Systems and Operating Systems Group in February 2002. He is working toward a Ph.D. in the area of "OS-directed power management", i.e. energy-aware operating system mechanisms and system design to account and reduce energy consumption. Research Interests As a member of the power management group at our department I am interested in energy-aware system design. Energy- related aspects of ubiquitous computing include: - power management techniques employed by energy-aware operating systems for (deeply) embedded systems, e.g. device shut-down policies, scheduling policies, processor core frequency/voltage scaling etc. - energy-aware operating system API (e.g. deferrable and abortable I/O operations) - accounting of energy consumption - application adaptation - trade-offs between energy consumption and quality of service - energy efficient communication in wireless (sensor) networks We investigate mechanisms to deduce the specific energy consumption from certain hardware event patterns. This helps in identifying the originator (energy principal) of a specific hardware activation. Towards this goal we both exploit hardware features already prevalent in today's microprocessors -such as performance counters- and also propose new architectural features specifically tailored to the problem domain at hand. Using information gathered this way efficient power management techniques can be applied. Several approaches of doing this are known, e.g. core frequency/voltage scaling. Other interests include pricing models and resource management based on energy consumption for servers and distributed systems.
