Conference paper (peer-reviewed)abstract
- Previously, business operations of most large companies were supported by a number of isolated software systems performing diverse specific tasks, from real-time process control to administrative functions. In order to better achieve business goals, these systems have in recent years been extended, and more importantly, integrated into a company-wide system in its own right, the enterprise software system. Due to its history, this system is composed of a considerable number of heterogeneous and poorly understood components interacting by means of equally diverse and confusing connectors. To enable informed decision-making, the Chief Information Officer (CIO), responsible for the overall evolution of the company's enterprise software system, requires management tools. This paper proposes enterprise software system architecture (ESSA) as a foundation for an approach for managing the company's software system portfolio. In order to manage the overwhelming information amounts associated with the enterprise software system, this approach is based on two concepts. Firstly, the approach explicitly relates the utility of knowledge to the cost of its acquisition. The utility of knowledge is derived from the increased value of better-informed decision-making. The cost of knowledge acquisition is primarily related to the resources spent on information searching. Secondly, the approach focuses on ensuring the consistency of the architectural model.

Conference paper (peer-reviewed)abstract
- The purpose of this paper is to investigatepossible change management implicationsfor networks organizations. This is achievedthrough applying six Critical ManagementIssues (CMI’s) from the changemanagement framework DELTA on ataxonomy consisting of three generic typesof network organizations. The paper is builton an empirical base comprised of over 150expert interviews and 121 questionnairerespondents. Questionnaire respondents andinterviewed experts represent middle to topmanagement of companies of all sizesinvolved in networks. The results show thatthe framework applied to the changemanagement in the different networkshighlights and addresses differentmanagement activities per CMI. Given this,we discuss the differences in managerialimplications that the framework identifiesfor the different types of networks.

ScrollPad : Tangible Scrolling with Mobile Devices
- 2004
-
In: Proceedings of the 37th Annual Hawaii International Conference on System Sciences (HICSS'04). - 0769520561 ; , s. 6-
-
Conference paper (peer-reviewed)abstract
- In this paper we approach the problem of managing large visual sets of data on small mobile devices. While current approaches either focuses on 1) scrolling on the mobile device, or 2) reducing the content in various ways (e.g. zooming, automatic redesign depending on the screen size of a mobile device, etc) our approach is to scroll with the mobile device itself (i.e. object in the world scrolling) over a large virtual area. We present the background for this project and working prototype called Scrollpad developed to illustrate this concept. We then present an initial user study conducted and relate this project to similar efforts made before concluding the paper.

Genre characteristics - a front page analysis of 85 Swedish online newspapers
- 2004
-
In: Proceedings of the 37th Annual Hawaii International Conference on System Sciences, 2004. - Los Alamitos, Calif. : IEEE Computer Society. - 0769520561 ; , s. 10-

Conference paper (peer-reviewed)abstract
- The online newspapers entered the Internet in the mid-nineties and since then it has become more and more common to read news online. There is a long tradition of designing newspapers in print but today there is a demand from both academics and practitioners for more knowledge about how to design user friendly news sites. The challenge is to design the online newspaper, in this rapidly changing media, to be the same familiar, user friendly and universally accepted product as the printed newspaper. We have designed a study in three parts to address this challenge. The overall research question is: How can design for a media in rapid development be communicated within a genre? The purpose of the first part of the study, presented in this paper, is to build a framework for identifying genre characteristics and to describe the Swedish online newspaper genre of today. We have conducted a front page analysis on the total population of 85 Swedish online newspapers. We suggest a quadruple of the genre concepts and a grid to handle positioning when building the framework. To describe the Swedish online newspaper genre we have used the taxonomy for the evolution of cybergenres together with the so called broadsheet metaphor. Aiming at a more comprehensive understanding of the online newspaper genre we modified the model by adding the leaf node 'progressed'.

Integrated ambient services as enhancement to physical marketplaces
- 2004
-
In: Proceedings of the 37th Annual Hawaii International Conference on System Sciences. - Los Alamitos, Calif : IEEE Computer Society Press. - 0769520561 ; , s. 4509-4516
-
Conference paper (peer-reviewed)abstract
- Ambient services are services that are related to the surrounding physical environment of the user, and can be considered a form of location-based services. Different kinds of ambient shopping services have been developed to aid users including brokerage services, navigational services, comparison shopping, product search, location-based auctions, wireless advertising, and even informational services where a user can point a device to a particular product or shop to find out more about it. With mobile devices, these services are made available at the point when the user needs it, for example, when they are at a shopping mall or in a busy tourist shopping complex. This paper proposes a conceptual framework of how a set of locally useful ambient services can be meaningfully organized based on the user's physical location and intended tasks to enhance a physical marketplace such as a shopping street or a shopping mall. We also outline an architecture for the system and how rule-based service composition can be performed on the client-side.

Open audio/video links as means for coordination - two case studies
- 2004
-
In: Proceedings of the Hawaii International Conference on System Sciences. - Los Alamitos : IEEE. - 0769520561 ; , s. 295-304
-
Conference paper (peer-reviewed)abstract
- From the multitude of workplace studies that we have seen during the last decades, it has been shown that a common environment to a large extent supports coordination of work. The use of common artifacts and awareness of the co-workers activities effortlessly afford communication of the current state of work. Inevitably, a question arises: how can we get similar support for distributed groups? One idea has been to use a continuously open video and/or audio link, i.e. a media space, to support the informal coordination possibilities that are lacking in a distributed setting. In this paper, two cases from air traffic control are presented, where the long-term use of video and audio links plays an important role for communicating real-time updates of the state of work. The possibility to overhear and oversee what the colleagues are doing in remote positions reduces to a large extent the amount of obtrusive and time-consuming phone calls. The features and the successful use of these so-called focused media spaces are discussed in this paper.

System Architecture for Psychological Customization of Communication Technology
- 2004
-
In: Proceedings of HICSS-37 Minitrack on Personalization Management System<em><em>s</em></em>. - 0769520561
-
Conference paper (peer-reviewed)abstract
- Personalization is a process that changes the functionality, interface, information content, or appearance of a system to increase its personal relevance to an individual. Personalization systems accommodate individual's needs and interests explicitly through changes and selections initiated by the user, and implicitly through automatic adaptation techniques. Currently most of the emphasis in personalization systems is geared towards the utilitarian aspects of personalized information delivery. However, what is lacking is the customization of information based on its likely emotional and cognitive effects on different users of communication technology. Information presented to individual users or a group of users may be customized on the basis of the immediate emotional and cognitive types of psychological effects it is likely to enable or create in certain individuals or groups. Both content and its way of presentation (modality, visual layouts, ways of interaction, structure) may be varied. Despite obvious complexities empirical evidence suggests that the way of presenting information to certain psychological profiles has predictable psychological effects. For instance, one may facilitate positive emotion for users with certain personality type or more efficient learning for certain cognitive styles. This is the basic concept of mind-based technologies. Psychological customization may be considered an operationalization and technique of implementing the concept of mind-based technologies in system design. Psychological customization may be used for controlling social interaction-centric and individual-centric influence of the content and way of presentation of information on consequent and transient emotional and cognitive effects. This paper explores the design space and presents a basic system architecture to implement psychological customization.
