M.; Kofod-Petersen, Anders; Unger, Herwig With the constant increase in smartphone sales, integrated sensors and map navigation have now become available to the average user. This allows for mobile applications to use context-awareness to provide more relevant information. An interesting use-case for such applications is a route information system for buses. The paper describes an application which interfaces over a mobile phone to Bus- TUC, a natural language-based reasoning-system for bus routes in Trondheim. By combining user context, BusTUC reasoning and real-time data from the bus service provider, the user-interaction is simplified, compared to a standard information system. We discuss issues on supporting context-awareness and real-time information in this system, comparing it to other available route information systems. Feedback from beta-testers indicates that the application suits the needs of typical bus travellers well. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/18203 Co-living social community for elderly Mathisen, Bjørn Magnus; Kofod-Petersen, Anders; Olalde, Idoia Eichler, Gerald; Wienhofen, Leendert W. M.; Kofod-Petersen, Anders; Unger, Herwig With a rapidly increasing elderly population, keeping elderly healthy is more important than ever. Physical and social activity is closely related to people's well-being. This paper describes some of the challenges faced when activating elderly people in an organised fashion. We propose a Virtual Collaborative Social Living Community for Elderly; utilising friends, family and care-professionals connected to the elderly in achieving this goal. Challenges related to this work in progress is then presented. The paper presents experiences made in an ongoing development and deployment of a socio-technical system. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/18205 Integrating the individual vehicle in the transport system using open services in a distributed architecture Moseng, Tor K.; Natvig, Marit Eichler, Gerald; Wienhofen, Leendert W. M.; Kofod-Petersen, Anders; Unger, Herwig Road traffic management has traditionally been targeted through control and monitoring of the flow of vehicles, using the same measures towards all vehicles. As vehicles can have very different capabilities and profiles, it is however desired to use different control strategies towards the individual vehicles to meet the environmental, safety and efficiency targets for the future. SMARTFREIGHT has developed a holistic control and monitoring tool for managing the traffic, and individual vehicles in particular. The individual vehicle is integrated with the traffic management and freight distribution management centers by using open service interfaces for an interoperable information exchange between distributed systems across a heterogeneous wireless infrastructure. SMARTFREIGHT realized and successfully demonstrated this integration in its final event in Trondheim. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/18206 A multiple platform approach to building a bus route information system for mobile devices Andersstuen, Runar; Engell, Trond Bøe; Sætre, Rune; Gambäck, Björn Eichler, Gerald; Wienhofen, Leendert W. M.; Kofod-Petersen, Anders; Unger, Herwig The paper describes a multiple platform-based approach to creating a bus route information system for mobile devices. The system is context aware: users only need to tell the system (in natural language) where they wish to go, and the system takes care of the rest. The users are presented with a list of possible routes they can take to reach their desired destination. The results are also shown on a map that makes finding the bus stops very easy. In order to make the system available to as many users as possible, the architecture is client-server-based and relies on technology standards that are widely accepted and implemented, making it easily adaptable to new platforms. The application can be run on multiple platforms, with a minimal amount of calculations needed on the client side. The amount of data transfer between server and client is also kept to a minimum. The ability to run on multiple different platforms is achieved using technology such as HTML5, PhoneGap and Sencha Touch. The client's functionality includes a search function and a map view, as well as the ability to use bookmarks. The server handles most of the business logic and communicates with external services such as the natural language processing back-end and the server for real-time bus departure information updates. 2012-01-01T00:00:00Z
