Can the Market Breakthrough in AAL Be Provided by a Large Scale Pilot?

2014

Ambient Assisted Living

Ambient Assisted Living (AAL) <6, 2013, Berlin, Germany>

Ambient Assisted Living is still on the cusp of a mainstream breakthrough, even though the market potential is tremendous. As barriers to the success of AAL, [1] mentions the lack of viable business models as well as the lack of ecosystems around common open platforms. Considering the fact that the EU has supported the development of universAAL as a true candidate for such common open platforms, this paper describes the next logical step towards the rollout of AAL throughout Europe based on this platform so that the foundation stone for the emergence of a self-organizing ecosystem is laid. In order to elaborate the feasibility of such rollouts, the European Commission published in early 2012 a CIP-ICT-PSP call for piloting AAL in large-scale based on interoperable platforms, where the winner was the proposal "make it ReAAL" that builds on universAAL as the common open platform. In addition to the applications coming with the universAAL Platform, the local vendors from each pilot region will offer their AAL products and services to the participating pilot sites. This means that a two-way adaptation is supposed to be addressed in ReAAL: on one hand, the universAAL native applications can be adapted to the requirements of the pilot sites, and on the other hand, the existing applications from the pilot regions can be integrated with the universAAL platform. Each Pilot site will then be able to select from this portfolio, those applications that are more suitable for their planned intervention. The mission of ReAAL is in this context to find out if the adaptation of a product to a common platform is economically reasonable when a company plans to enter the market with a new product idea. Based on this, ReAAL will hopefully show the cost-effectiveness of interoperable solutions compared to both vertical isolated solutions and comprehensive but closed systems. This should pave the way for the emergence of an ecosystem around a common open platform and based on that for the market breakthrough of AAL through interoperability.

Kann der Marktdurchbruch in AAL durch ein großangelegtes Pilotvorhaben erreicht werden?

2013

Lebensqualität im Wandel von Demografie und Technik

Ambient Assisted Living (AAL) <6, 2013, Berlin, Germany>

Trotz des großen zukünftigen Marktpotenzials für die Industrie steht die AAL-Branche immer noch nicht vor dem Durchbruch. Als Barriere hierfür werden einerseits fehlende Geschäftsmodelle und andererseits fehlende Ökosysteme um gemeinsame offene Plattformen genannt. Nachdem nun die EU die Entwicklung von universAAL als ein echter Kandidat für eine solche gemeinsame offene Plattform gefördert hat, beschreibt dieser Beitrag den nächsten logischen Schritt, AAL basierend auf dieser Plattform europaweit auszurollen, damit der Grundstein für die Entstehung eines selbstorganisierenden Ökosystems gelegt ist. Um die Machbarkeit nachweisen zu können, hatte die Europäische Kommission eine Ausschreibung für Pilotregionen im PSP-CIP-Programm veröffentlicht, deren Anwendungen auf interoperable Plattformen basieren sollen. Das Projekt, das gewonnen hat, war "make it ReAAL", das auf die universAAL Plattform als die gemeinsame offene Plattform aufbaut. In ReAAL stellen die lokalen Anbieter aus den Pilotregionen zusätzlich zu den von universAAL angebotenen Anwendungen weitere Dienste zur Verfügung. So können einerseits universAAL- native Applikationen an die Bedürfnisse der Regionen adaptiert werden, und andererseits bestehende Anwendungen der Pilotregionen an die Plattform angebunden werden. Jede Pilotregion selektiert dann aus diesem Set an Anwendungen, genau solche, die ihre Bedürfnisse am besten erfüllen Die Mission von ReAAL ist es, somit herauszufinden, ob eine Adaption von Produkten auf einer gemeinsamen offenen Plattform ökonomisch sinnvoll ist, wenn ein Unternehmen eine eigene Produktidee auf den Markt bringen möchte. Mit dieser Vorgehensweise wird durch ReAAL hoffentlich nachgewiesen, dass Interoperabilität billiger ist als sowohl vertikal isolierte Lösungen als auch umfassende aber geschlossene Systeme. Somit kann der Weg für die Entstehung eines Ökosystems um eine gemeinsame offene Plattform geebnet und basierend darauf der Marktdurchbruch von AAL durch Interoperabilität erzielt werden.

Zugriffskontrolle in Intelligenten Umgebungen

2013

Darmstadt, TU, Bachelor Thesis, 2013

Das Ziel dieser Arbeit ist, die Sicherheit in intelligenten Umgebungen zu analysieren, Bedrohungen zu beschreiben, und eine Zugriffskontrolle als Lösung zu konzipieren. Dies ist entscheidend, da intelligente Umgebungen immer mehr Einzug in den Alltag der Menschen erhalten und ihnen dort sehr verantwortungsvolle Aufgaben übertragen werden, bei denen eine Fehlfunktion oder ein Angriff besonders dramatische Folgen hat. In dieser Arbeit wird zunächst der aktuelle Stand zur Sicherheit in verteilten, intelligenten Umgebungen beschrieben, dann auf die Middleware universAAL und andere verteilte Umgebungen eingegangen, und eine Zugriffskontrolllösung für das Senden und Empfangen von Nachrichten innerhalb der Umgebung konzipiert, bei der der Nutzer bei der Installation für jede Nachricht das Empfangen erlaubt oder verbietet. Die Realisierung auf Basis von universAAL wird dargestellt und besprochen, die Probleme die dabei auftraten, und aufgrund derer eine Evaluierung der Realisierung nicht möglich war, werden benannt. Das Ergebnis der Arbeit ist, dass Zugriffskontrolle in verteilten Umgebungen eine entscheidende Rolle spielt, bisher wenig funktionierende Implementierungen existieren, und eine Realisierung auf Basis einer Manifest-Datei, bei der der Nutzer bei der Installation eine Policy erstellt, möglich ist.

3D Interaction in AAL Environments Based on Ontologies

2012

Ambient Assisted Living

Ambient Assisted Living (AAL) <5, 2012, Berlin, Germany>

The interaction between a technical system and the user is a main issue in information technology. In the field of Ambient Assisted Living (AAL) this is even more important due to the physical or mental restrictions of the users. Explicitly controlling a technically heterogeneous environment like a living area can be very complicated (e.g. using remote controls with complex interfaces) or even physically annoying (e.g. searches remote controls or need to walk to a light switch). Thus, it is desirable to control the environment by simple pointing gestures or by using a centralized device. The base for this is a valid 3D representation of the environment including all required elements. In this paper, we present a new approach of an ontological representation of the real world and the dynamic service in-vocation according to this ontological 3D information. This concept is further described and validated by two application examples using a 3D GUI at a Tablet-PC and pointing gestures to control the AAL Space.

How to Overcome the Market Entrance Barrier and Achieve the Market Breakthrough in AAL

2012

Ambient Assisted Living

Ambient Assisted Living (AAL) <5, 2012, Berlin, Germany>

Since the changing demographics the European Commission as well as near all national funding organisations see the necessity to support assisted technologies through huge funding instruments. Despite its tremendous market potential, AAL (Ambient Assisted Living) is still on the cusp of a mainstream break-through. A lack of viable business models is considered almost unanimously to be the greatest market obstacle to a broad implementation of innovative AAL systems. This paper describes the sustainable approach by universAAL and AALOA to overcome this market entrance barrier by mobilizing the AAL community and influencing the funding programs to achieve the market breakthrough in AAL.

Technology, Platforms, Standards, Interoperability

2012

Partnerships for Social Innovation in Europe

AAL Forum <3, 2011, Lecce, Italy>

As a multidisciplinary technological approach, AAL involves (too) many different standards at diverse Ievels of hardware, software ( architectures and interfaces ), processes and services, data and content, etc. Considering that even simple sensors and actuators from a single domain are not interoperable by themselves, it should be obvious that complexity increases dramatically when several different domains, such as health, well-being, comfort, entertainment, safety and security, home automation, and energy efficiency, are considered in a combined way for creating AAL applications and services. Hence, the AAL Forum 2010 organised Track F on "Technology, Platforms, Standards, lnteroperability" to investigate two closely-related questions: the role of standards and platforms in coping with the challenge of interoperability in AAL as weil as the obstacles to their wider adoption by technology providers. Since neither the creation of the AAL platforms nor the development of related standards is in the focus of the AAL Joint Programme per se, it was expected that this track would play a bridging role between AAL JP on the one side, and the more longterm industrial activities towards standards as well as the strategic research on AAL platforms in the context of the Framework Programmes of the European Commission on the other. Consequently, Track F was organised in four preparatory sessions for looking at the standardisation and platform scene and collecting views on obstacles and possible strategies for overcoming them. In a fifth session, this track finished its work by a panel discussion for summing up the collected information and making recomrnendations to the AAL comrnunity and its Joint Programme. The following is a summary of these five sessions.

The universAAL Reference Model for AAL

2012

Handbook of Ambient Assisted Living

Ambient Assisted Living (AAL) is lacking a reference model that can serve as a basis for understanding the main issues to be addressed without any solution bias. Such a reference model will facilitate consensus-building processes and consolidation efforts towards converging conclusions on AAL infrastructures. The universAAL project, that aims at producing an open platform along with a standardized approach for making it technically feasible and economically viable to develop AAL solutions, has defined a process consisting of four iterations for filling this gap. Here, the results of the first iteration on a reference model for AAL are presented.

Der Weg zu einer universellen Ambient Assisted Living und Personal Health Umgebung

2011

Ambient Assisted Living

Ambient Assisted Living (AAL) <4, 2011, Berlin, Germany>

Durch den demographischen Wandel bedingt, bieten Wohnen und Pflege in der gewohnten häuslichen Umgebung für einen immer größer werdenden Anteil der Bevölkerung eine attraktivere Alternative zur stationären Unterbringung. Trotz des großen zukünftigen Marktpotenzials für einschlägige Unternehmen steht die AAL-Branche jedoch noch nicht vor dem Durchbruch. Als größtes Markthemmnis für einen breiten Einsatz innovativer Assistenzsysteme werden nahezu übereinstimmend fehlende Geschäftsmodelle genannt. Dieser Beitrag beleuchtet, wo Gründe hierfür liegen können und zeigt auf, warum die AAL-Community nicht um Gesamtlösungen auf Basis einer einheitlichen AAL-Referenzplattform herumkommt. Er beschreibt aber auch das enorme Potenzial von AmI und AAL, das durch universAAL und AALOA erstmals eine wirkliche Chance erhält.

Ambient Intelligence

International Joint Conference on Ambient Intelligence (AmI) <2, 2011, Amsterdam, The Netherlands>

The digital agenda of the European Commission includes plans for the building of Information and Communication Technology (ICT) based on a new generation of networks, or the Internet of the Future. To this end, the Future Internet Private Public Partnership (FI-PPP) has been established with the help of the European Commission. It will involve the building of a proof of concept FI platform in the coming two years. One of the main challenges of this platform is to be generic while serving the needs of specific application sectors. This workshop will focus on the challenges of integrating Ambient Intelligence (AmI) and Ambient Assisted Living (AAL) platforms with this kind of platform. Participants in the workshop will include members of the AmI/ AAL platform community, members of the FI community, and policy makers.

Towards a Unified Ambient Assisted Living and Personal Health Environment

2011

Ambient Assisted Living

Ambient Assisted Living (AAL) <4, 2011, Berlin, Germany>

Due to the changing demographics, residing and being cared in the own familiar environment is becoming the more attractive alternative for an ever increasing portion of the population in contrast to an institutionalized inpatient setting. Despite its tremendous market potential, AAL (Ambient Assisted Living) is still on the cusp of a mainstream break-through. A lack of viable business models is considered almost unanimously to be the greatest market obstacle to a broad implementation of innovative AAL systems. This paper highlights possible explanations for this deficit and shows why the AAL community has yet to arrive at joint solutions based on a unified AAL reference platform. Furthermore, this paper describes the enormous potential of AmI and AAL, as the first real opportunity for their success is provided through universAAL and AALOA.

UniversAAL - an Open and Consolidated AAL Platform

2011

Ambient Assisted Living

Ambient Assisted Living (AAL) <4, 2011, Berlin, Germany>

Due to the demographic development towards an ageing society AAL technologies will play an important role in the future. There has been a lot of work done in the field of AAL, but most of the project outcomes are proprietary and thus impossible to be combined. Accordingly, there is a need for an universal and open platform, which can be used as a starting point for further developments or just as an integration and standardization tool. For future service platform related research projects reference use cases as well as a reference tool set and framework would help to ensure a reusable and expandable platform, which is wide spread and therefore ensures a quality of service. The aim of the universAAL project is to combine the advantages and strengths of still ongoing or already finished research projects to create an universally applicable platform. The focus thereby is on interoperability and standardization to ensure a broad range of applicability and to develop an open platform that will make it technically feasible and economically viable to develop AAL applications. There are two tools for spreading the outcomes and ideas of the project planned: On the one hand the establishment of a store providing plug-and-play AAL applications and services that support multiple execution platforms and can be deployed to various devices and users, and on the other hand the AAL Open Association (AALOA) with the mission to create a platform for identifying key research topics in AAL, and to reach agreement on prioritization of these and to design, develop, evaluate and standardize a common service platform for AAL.

universAAL - eine offene und konsolidierte AAL-Plattform

2011

Ambient Assisted Living

Ambient Assisted Living (AAL) <4, 2011, Berlin, Germany>

Auf Grund von demographischen Entwicklungen hin zu einer alternden Gesellschaft werden AAL-Technologien und Anwendungen eine immer bedeutendere Rolle spielen. Zahlreiche nationale und internationale AAL-Projekte haben überwiegend zu proprietären Lösungen geführt, die nur schwer und mit großem Aufwand miteinander kombinierbar und integrierbar sind. Eine universelle und offene Plattform könnte ein Start für zukünftige Entwicklungen und eine Basis für die Integration standardisierter AAL-Services sein. Das Ziel des universAAL Projektes soll es sein, die Vorteile und Stärken von acht teilweise noch laufenden und abgeschlossenen FP6 und FP7 EU-Projekten zu kombinieren und eine universelle AAL-Plattform zu generieren. Der Fokus liegt dabei auf Interoperabilität und Standardisierung, um die Voraussetzungen zu schaffen, möglichst viele AAL-Anwendungen und Services zu integrieren und es ökonomisch attraktiv zu machen, individuelle AAL-Anwendungen zu generieren. Ziel des Projekts ist auch eine Community zu etablieren, die bereits während der Projektlaufzeit die Projektergebnisse nutzt bzw. eigene Komponenten beiträgt. Ein Software Store und Ressourcen, welche verschiedenste Betriebssysteme unterstützen, werden als Basis Entwicklern als auch Endanwendern bereitgestellt. Eine offene Gesellschaft (AALOA) soll die Interessen an AAL Lösungen verschiedenster Stakeholder zusammenführen und die Community bilden, die offene und standardisierte Komponenten auch über die Projektlaufzeit hinaus unterstützt.

An Open Distributed Framework for Adaptive User Interaction in Ambient Intelligence

2010

Ambient Intelligence

International Joint Conference on Ambient Intelligence (AmI) <1, 2010, Malaga, Spain>

Challenges of handling user interaction in Ambient Intelligence environments are manifold. The systems installed in these environments are highly distributed with dynamic configurations in terms of integrated devices and installed applications. Context-awareness, personalization, and multimodality are critical for supporting more natural interaction and optimizing the interaction in an adaptive way. Research activities have dealt with different specific problems in the field and now it is high time for moving towards an open framework with a more comprehensive solution. This paper introduces results of such work with a high level of freedom in developing and deploying applications without needing to care about the available I/O infrastructure. The other way around, the latter can be changed without worrying about the application side. The independence of applications from the available I/O infrastructure helps to share mechanisms and manage such a complex scene more adequately. The key idea behind this framework is the natural distribution of tasks according to the real scene using a middleware solution supporting seamless connectivity and goal-based interoperability.

The PERSONA Service Platform for AAL Spaces

2010

Handbook of Ambient Intelligence and Smart Environments

Ambient Assisted Living (AAL) is the concept that groups the set of technological solutions, named AAL Services, targeting the extension of the time that elderly and disabled people live independently in their preferred environment, i.e. their own four walls, neighborhood and town where they are used to live [1]. AAL Services provide personalized continuity of care and assistance, dynamically adapted to the individual needs and circumstances of the users throughout their lives. The main objective of PERSONA is the development of a scalable open standard technological platform to build a broad range of AAL Services. A number of AAL Services are being implemented over such a platform in order to demonstrate, test and evaluate their social impact and potential exploitation scenarios. AAL Services under development are divided into four different categories according to an analysis of elderly needs in regard to a life with the highest level of independence.

Using Queries for Semantic-based Service Utilization

2009

Proceedings of the 3rd International Workshop on Service Matchmaking and Resource Retrieval in the Semantic Web

International Workshop on Service Matchmaking and Resource Retrieval in the Semantic Web (SMR2) <3, 2009, Washington DC, USA>

A vision of the Semantic Web is to facilitate global software interoperability. Many approaches and specifications are available that work towards realization of this vision: Service-oriented architectures (SOA) provide a good level of abstraction for interoperability; Web Services provide programmatic interfaces for application to application communication in SOA; there are ontologies that can be used for machine-readable description of service semantics. What is still missing is a standard for constructing semantically formulated service requests that solely rely on shared domain ontologies without depending on programmatic or even semantically described interfaces. Such a standard would facilitate the realization of Semantic RPC as the whole process from issuing such a request, matchmaking with semantic profiles of available and accessible services, deriving input parameters for the matched service(s), calling the service(s), getting the results, and mapping back the results onto an appropriate response to the original request. The standard must avoid realization-specific assumptions so that frameworks supporting semantic RPC can be built for bridging the gap between the semantically formulated service requests and matched programmatic interfaces. This paper introduces a candidate solution to this problem by outlining a query language for semantic service utilization based on an extension of the OWL-S ontology for service description.

The PERSONA Framework for Supporting Context-Awareness in Open Distributed Systems

2008

Ambient Intelligence

European Conference on Ambient Intelligence (AmI) <2, 2008, Nürnberg, Germany>

Although several context-aware systems have been developed within the past 15 years that use contextual info captured from the physical environment in combination with system usage context and personalization data, it seems that a breakthrough has not been achieved yet, because still more and more research projects work on adequate solutions for supporting context-awareness. It seems that the major difficulties have to do with a hurdle called context modeling and its extensibility as well as the open nature of such systems that must allow for dynamic pluggability of components distributed over several physical nodes. This paper presents the related work results from the EU project PERSONA that feature remarkable conceptual solutions for the above issues. It consists of a middleware solution for open distributed systems dealing with seamless connectivity and adequate support for interoperability that makes use of ontological technologies and defines appropriate protocols along with an upper ontology for sharing context. A set of standard platform components together with a general conceptual solution for binding ultra-thin nodes top off the presented approach.

With the motto "get informed, orientate yourself, organize your visit, and experience the world cup", the goal of the R&D project servingo was to support the visitors of the FIFA world cup 2006 by providing a personalized single point of access to various services and information from different areas, such as tourism, location-based services, and infotainment. One of the major challenges within the project was the question about Web-based portal framework with an appropriate solution for context-aware service provision. This paper introduces the work results in this later area, where servingo had to deal with the requirement to present the available, complex information to users in a straightforward way. Internally, servingo manages the relevent user-centered context data as the main source for personalization, providing a framework for context-aware-aware service brokerage, which is based on the Semantic Web Services approach.

Although mobile knowledge management (mKM) is being perceived as an emerging R&D field, its concepts and approaches are not well-established, as compared to the general field of Knowledge Management (KM). In this paper, we try to establish a definition for mKM. Taking into account building blocks of KM in enterprises and the abstract use cases of mKM systems, we introduce a reference architecture for mKM systems as a basis for verifying and comparing concepts and system architectures. Finally, we address the potential suitability of mKM as a prototype model for mobile, situation-aware information processing in the field of Ambient Intelligence Environments.

Mobile Work Employs IT (MoWeIT) <2005, Prag, Czech Republic>

In addition to the traditional field services, market observations show that due to the increasing quality improvements and cost reductions in the transportation and communication, the number of mobile workers is growing rapidly. Businesses hope to improve the quality of their services and products by increasing the direct contacts to their customers and partners. From the IT point of view, one of the immediate consequences is the increasing demand for being integrated into the global and corporate network. However, for a closer look at the requirements of mobile work on IT, an analysis of mobile work appears to be indispensable. This paper aims at contributing to filling this gap. After a survey of existing explorations on mobile work and adding our observations from the domain of facility management, we summarize the results of a SWOT analysis that has been performed within the project Mummy1, and try to extract the essential requirements of mobile work on IT, especially from the Knowledge Management point of view.

The importance of contextual knowledge in knowledge management and organizational memory is shown in topical literature. Even in an initial visionary scenario for the Semantic Web, one can immediately encounter the contextual knowledge needed to realize the necessary services. Hence, it is not inappropriate to claim that context management is an integral service of the Semantic Web. After discussing the distributed nature of contextual knowledge, we define some requirements for a context-oriented database service and then introduce CORD as a service satisfying those requirements based on the Semantic Web technologies. Selected features of CORD that provide some contribution to the discussions within the Semantic Web research community, like embedded resources, query language, and definition of rules, are discussed in some detail.

Hypervideo content can be understood as a video-based hypermedia information structure providing a user the option to exert influence on the way the video-related content is presented. It offers a user the opportunity to take an active part in the presentation. It has been proven that the combination of interactivity, video content and multimedia documents forming a hypermedia structure is a powerful way to present information. Collaborative knowledge construction within communities on the Internet is a hot topic today, providing support for exchanging and retrieving multimedia content based on group conversation. With this paper, we announce a first approach to a hypervideo collaborative learning interface concept for mobile environments. This approach enables users to extend the interactive video content with multimedia documents during a presentation in order to exchange and share experiences and views with other members within a mobile community.

Kooperiert der Nutzer - wie bislang - direkt mit den einzelnen Agenten, verliert er bei steigender Anzahl der dienstanbietenden Agenten leicht den Überblick über die von ihm delegierten Aufgaben. Um dem Nutzer unter solchen Bedingungen weiterhin ein einfaches und unkompliziertes Arbeiten mit Agenten zu gestatten, muss eine Möglichkeit geschaffen werden aus dem Angebot der Dienste wählen und somit Agenten einheitlich Aufträge erteilen zu können. Gegenstand der Arbeit ist die Konzeption und Umsetzungen eines gesonderten Agenten - dem Broker-Agenten, der den Nutzer in dieser Hinsicht unterstützt und Dienste ad hoc zu vermitteln vermag. Das Konzept des Broker-Agenten sieht vor Agenten und ihre Dienste mittels Metadaten zu modellieren, um die Vermittlung auf dieser Basis stattfinden zu lassen. Mögliche Lösungsansätze müssen folglich ein einheitliches Modell zur Definition von Metadaten bereitstellen sowie über eine hinreichend definierte Syntax und Semantik verfügen, sodass Agenten eigenständig und unabhängig von menschlichem Eingreifen die Merkmale eines Dienstes ableiten können. Vor diesem Hintergrund werden zwei Ansätze gegenübergestellt und auf die genannten Kriterien hin untersucht: die Web Service Description Language (WSDL) und die DAML Web Services Ontology (DAML-S). Allein DAML-S erfüllt mittels der Ausdrucksstärke und umfassenderen Typisierung einer Ontologie die gestellten Anforderungen an eine Sprache zur Beschreibung von Diensten. Die Arbeit führt in der Folge eine eigenständige Ontologie zur Modellierung von Agenten - in Form so genannter Agentenprofile - ein und erweitert DAML-S um spezifische Merkmale zum Einsatz in einer agenten-gestützten Umgebung. Unter Berücksichtigung der im Konzept festgehaltenen Merkmale stellt die Arbeit die prototypische Umsetzung des Broker-Agenten an Hand eines Szenarios vor und zeigt die in ihrem Verlauf erstandenen, konkreten Ergebnisse auf. Diese lassen sich zusammenfassend in drei Aspekte einteilen: die Modellierung von Agenten und ihren Diensten mittels Profile, die Vermittlung der Dienste auf Basis dieser Profile und der Zugriff auf Dienste durch den Nutzer zu jeder Zeit, von jedem Ort und von beliebigen Endgeräten. Abschließend betrachtet die Arbeit offene Fragen, die Erweiterungsmöglichkeiten aufzeigen und diskutiert Möglichkeiten, flexibler auf den Ausfall von Komponenten zu reagieren, Dienste umfassender zu interpretieren sowie die Interaktion des Nutzers mit dem Broker-Agenten noch einfacher zu gestalten.

Mobile Situation-awareness within the Project Map

2003

Computers & Graphics

Mobile devices as PDAs evolve rapidly from digital calendars and address books to hosts of more complex functionality. Mobile access to business information such as customer, product or project databases is seen as one of the cutting edge IT solutions for improving productivity and customer satisfaction. However, mobility and scaled-down mobile technology lead to speci.c limitations in contrast to the usage of desktop computers. These restrictions are absolutely crucial to consider for the development of usable mobile applications. With reference to the project map - Multimedia Arbeitsplatz der Zukunft (Multimedia Workplace of the Future), this article outlines our main approach to situation-aware support for mobile workers in response to mobile restrictions. We are pointing out focal components and sketch parts of the map architecture, in particular the prototypical application ''BuddyAlert''.

A major problem in the domain of context-aware and adaptive HCI is the lack of a shared understanding of context. Many of the existing context-aware applications act independently from a shared context management service relying on a curtailed context model not appropriate for interoperability between independently running components. This paper aims at identifying the core of context parameters for a mobile user, followed by a discussion about the classification of these parameters. For each identified class, the most important properties are then determined. The context model presented here is a result of our two major projects from the domain of mobile workplaces and mobile knowledge management (map and mummy ). Most parts of the model, however, can be applied in arbitrary scenarios and systems.

In mobile environments, the usage of mobile agents is very common. After being configured by the user, mobile agents can perform tasks autonomously and present their results when they have finished their task. In most cases, communication between user and agent is only necessary at the time of configuration and at the time of presentation, when the agent has accomplished its task. Our research activities deal with agent-based applications for mobile users with mobile devices of low processing power and without Java capabilities, which yields the question of how user interfaces can be implemented. In this paper, different approaches for the communication between users and agents are summarized and classified with respect to our applications. An agent platform gateway is introduced as our approach to user interface implementation and some services of the gateway are described in detail.

User-Centric Service Brokerage in a Personal Multi-Agent Environment

2003

International Conference on Integration of Knowledge Intensive Multi-Agent Systems

International Conference on Integration of Knowledge Intensive Multi-Agent Systems (KIMAS) <2003, Cambrige, MA, USA>

Service brokerage is a central issue in multi-agent systems. Existing approaches often address the brokering among agents in terms of cooperative problem solving. Our work, however, deals with brokering the services offered to users in a multi-agent system. The user should be able to choose the desired services and assign concrete tasks to the service-offering agents utilizing those services. To this end, we based our work on the "Semantic Web Services" approach. After pointing out the problems the users and agents are faced with, we discuss some related approaches and introduce the results of our work: a broker agent as a user service of the agent platform.

Practical Aspects of Knowledge Management. PAKM 2002. Proceedings

Practical Aspects of Knowledge Management (PAKM) <4, 2001, Vienna, Austria>

Mobile devices as PDAs evolve rapidly from digital calendars and address books to hosts of more complex functionality. Screen quality, processing power and mobile networks allow for full-blown mobile information systems. However, mobility and down scaled technology lead to specific limitations in contrast to the usage of desktop computers. These restrictions are absolutely crucial to consider for the development of usable mobile applications. In this paper we are going to derive basic requirements for mobile knowledge management and present a first approach to possible solutions within the area of project management work. Underlying technical and human constraints are drawn from a general discussion of mobile information access and processing. We are pointing out focal components and problems to address. Finally our main concept of context-aware KM is sketched, building on the idea of Knowledge Portals and prototyped as the "BuddyAlert"-system.
