A simplistic approach to keyhole plan recognition

When applying plan recognition to Human - Computer Interaction, one must cope with users exhibiting a large amount of reactive behaviour: users that change tasks, or change strategies for achieving tasks. Most current approaches to keyhole plan recognition do not address this problem. We describe an application domain for plan recognition, where users exhibit reactive rather than plan-based behaviour, and where existing approaches to plan recognition do not perform well. In order to enable plan recognition in this domain, we have developed an extremely simplistic mechanism for keyhole plan recognition, "intention guessing". The algorithm is based on descriptions of observable behaviour, and is able to recognize certain instances of plan failures, suboptimal plans and erroneous actions. At run-time, the algorithm only keeps track of a limited number of the most recent actions, which makes the algorithm "forgetful". This property makes the algorithm suitable for domains where users frequently change strategies

A Recipe Based On-line Food Store

In this paper we present a recommender system design for recipe based on-line food shopping. Our system differs in two major ways from existing system. First we use an editor that labels clusters of users, such as meat lovers and vegetarians; based on what recipes they have chosen. Secondly, these clusters are available to users, so they can not only choose recipes based on their own user group but also navigate among other user groups

The Ubiquitous Interactor - Device Independent Access to Mobile Services

The Ubiquitous Interactor (UBI) addresses the problems of design and development that arise around services that need to be accessed from many different devices. In UBI, the same service can present itself with different user interfaces on different devices. This is done by separating interaction between users and services from presentation. The interaction is kept the same for all devices, and different presentation information is provided for different devices. This way, tailored user interfaces for many different devices can be created without multiplying development and maintenance work. In this paper we describe the system design of UBI, the system implementation, and two services implemented for the system: a calendar service and a stockbroker service

Enhanced reality live role playing

Live role-playing is a form of improvisational theatre played for the experience of the performers and without an audience. These games form a challenging application domain for ubiquitous technology. We discuss the design options for enhanced reality live role-playing and the role of technology in live role-playing games

The psychosocial work environment of nurses

Bakgrund: En väl fungerande psykosocial arbetsmiljö är den som anpassas efter individers behov och begränsningar. Sjuksköterskan har genom historien utsatts för hårda prövningar då yrket har setts som ett kall snarare än en profession, vilket har lett till hög arbetsbelastning och låg status. Hälso- och sjukvårdslagen, arbetsmiljölagen och patientsäkerhetslagen beskriver hur god vård och bra arbetsmiljö ska samverka för att gynna både vårdpersonal och patienter. Arbetsmiljöverket beskriver olika faktorer som kan skapa en dålig psykosocial arbetsmiljö, exempelvis högt arbetstempo, oklara roller och ständiga förändringar. En arbetsmiljö som är begriplig, hanterbar och meningsfull skapar arbetstillfredsställelse och ökar välmåendet. Syfte: Att undersöka hur sjuksköterskor upplever och hanterar den psykosociala arbetsmiljön. Metod: Denna litteraturöversikt bygger på tio vetenskapliga artiklar, både kvalitativa och kvantitativa, som valdes ut efter en systematisk litteratursökning i databaserna Cinahl och PubMed. Inklusions- och exklusionskriterier gjorde att de utvalda artiklarna svarade mot syftet. Resultat: Följande sex kategorier upptäcktes som beskriver hur sjuksköterskor upplever och hanterar sin psykosociala arbetsmiljö: Maktlöshet, Splittrad yrkesroll, Samarbetsproblematik, Obelönt arbete/Ingen uppskattning, Ökade krav/Ökande arbetsbelastning och Strategier och tankar kring påfrestningar

Mobile Life: A Research Foundation for Mobile Services

The telecom and IT industry is now facing the challenge of a second IT-revolution, where the spread of mobile and ubiquitous services will have an even more profound effect on commercial and social life than the recent Internet revolution. Users will expect services that are unique and fully adapted for the mobile setting, which means that the roles of the operators will change, new business models will be required, and new methods for developing and marketing services have to be found. Most of all, we need technology and services that put people at core. The industry must prepare to design services for a sustainable web of work, leisure and ubiquitous technology we can call the mobile life. In this paper, we describe the main components of a research agenda for mobile services, which is carried out at the Mobile Life Center at Stockholm University. This research program takes a sustainable approach to research and development of mobile and ubiquitous services, by combining a strong theoretical foundation (embodied interaction), a welldefined methodology (user-centered design) and an important domain with large societal importance and commercial potential (mobile life). Eventually the center will create an experimental mobile services ecosystem, which will serve as an open arena where partners from academia and industry can develop our vision an abundant future marketplace for future mobile servíces

ConCall: An information service for researchers based on EdInfo

In this paper, we present new types of web information services, where users and information brokers collaborate in creating a user-adaptive information service. Such services impose a novel task on information brokers: they become responsible for maintaining the inference strategies used in user modeling. In return, information brokers obtain more accurate information about user needs, since the adaptivity ensures that user profiles are kept up to date and consistent with what users actually prefer, not only what they say that they prefer. We illustrate the approach by an example application, in which conference calls are collected and distributed to interested readers
