Considering the importance of user profiles in interface design
- 2009
-
Ingår i: User Interfaces. ; , s. 23-
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- User profile is a popular term widely employed during product design processes by industrial companies. Such a profile is normally intended to represent real users of a product. The ultimate purpose of a user profile is actually to help designers to recognize or learn about the real user by presenting them with a description of a real user’s attributes, for instance; the user’s gender, age, educational level, attitude, technical needs and skill level. The aim of this chapter is to provide information on the current knowledge and research about user profile issues, as well as to emphasize the importance of considering these issues in interface design. In this chapter, we mainly focus on how users’ difference in expertise affects their performance or activity in various interaction contexts. Considering the complex interaction situations in practice, novice and expert users’ interactions with medical user interfaces of different technical complexity will be analyzed as examples: one focuses on novice and expert users’ difference when interacting with simple medical interfaces, and the other focuses on differences when interacting with complex medical interfaces. Four issues will be analyzed and discussed: (1) how novice and expert users differ in terms of performance during the interaction; (2) how novice and expert users differ in the perspective of cognitive mental models during the interaction; (3) how novice and expert users should be defined in practice; and (4) what are the main differences between novice and expert users’ implications for interface design. Besides describing the effect of users’ expertise difference during the interface design process, we will also pinpoint some potential problems for the research on interface design, as well as some future challenges that academic researchers and industrial engineers should face in practice.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to examine and discuss the effects of quality management in the health care sector and the general effects of quality management on the health of the employees. Methodology/approach The empirical basis consists of three case studies in one industrial manufacturing company and two hospitals. The empirical data have been gathered with both qualitative and quantitative methods. Findings: The twofold value of quality management, of preventing disease by supporting more rewarding working conditions as well as improving the treatment of disease by increasing the effectiveness of health care organisations it indicated. Leadership commitment was found to be the most crucial common prerequisite for successful quality management implementation and for creating a healthy work environment. In addition, continuous improvements and participation of everybody were found to have importance for well functioning quality management as well as for health. Research limitations/implications: The paper provides additional understanding of the influence of quality management on health and a model is presented. A limitation is that the factors studied are fairly broad and for further research it will be useful to go deeper into the mechanics of them. Practical implications: The three factors leadership commitment, participation of everybody and continuous improvements have been shown to be vital contributors for health and managers should make every effort to implement them. Originality/value: The double effect of quality management on health has not been studied before and knowledge of the factors contributing to it is valuable.

Computational Aeroacoustics Based on Large Eddy Simulation and Acoustic Analogies
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The thesis presents a numerical method developed by the author and its applications for computing the generated sound by an unsteady flow field and its propagation. The full equations of motion for compressible and unsteady flows describe both flow field and sound generation and propagation. It is assumed that the flow variables can be decomposed into semi-compressible / incompressible components and inviscid, irrotational acoustic components. The present method is based on Large Eddy Simulation (LES) to compute the turbulent flow and an approach based on an inhomogeneous wave equation to compute the radiated acoustic field. In this way one can avoid the necessity for a very large computational effort associated with direct simulation of the near- and specially far- field sound generated by a turbulent flow. The governing equations are written in the form of a non-homogeneous wave equation for the acoustic fluctuation with acoustic sources on the right-hand side. The thesis includes the details of the coupling between the flow solver and the acoustic one, as well as the results for test cases employed to validate the numerical algorithm and the implemented boundary conditions. The method has been successfully applied to compute the near- and far- acoustic fields generated by various unsteady flows such as a round hot turbulent jet ejected from a pipe close to a solid boundary, coaxial turbulent non-isothermal jets (separate exhaust system), or the flow around a wind-turbine.

Machine Interpretable Representation of Commander's Intent

Konferensbidrag (refereegranskat)abstract
- The Network-Centric approach envisioned in the Global Information Grid enables the interconnection of systems in a dynamic and flexible architecture to support multi-lateral, civilian and military missions. Constantly changing environments require commanders to plan for missions that allow organizations from various nations and agencies to join or separate from the teams performing the missions, depending on the situation, as missions unfold. The uncertainty within an actual mission, and the variety of potential organizations that support the mission after it is underway, makes Command Intent (CI) a critical concept for the mission team. With new and innovative information technologies, CI can now be made available to the team of organizations in a coalition environment. Using a flexible and linguistically based approach for representing CI allows Intent to be interpreted and processed by all participants – both humans and machines. CI representations need to be able to express mission team’s purpose, the anticipated End-State of the mission and desired key tasks. In this work, the expression of CI is developed to enable the structure and dynamics of collaboration support.

Konferensbidrag (refereegranskat)abstract
- In a fiercely competitive business climate, which is increasingly characterized by global alliances, partnerships and outsourcing agreements, companies struggle to decrease the negative impact of geographic distance on development efforts. The role of workspaces for collaborative design is gaining considerable attention, and there is currently an increasing interest in moving from individual tools or technologies to a more inclusive view of collaborative workspaces. This paper reports on the underlying motivation and justification for a new collaborative design studio at Luleå University of Technology, Sweden. The studio provides a rapid-response environment, in which the significance of issues raised through ethnographic observations of engineering work can be evaluated and solutions offered.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Today’s collaboration tools can support formal meetings to a certain extent, though there is still an immense potential for improvement when it comes to designing virtual and physical places where global design teams can collaborate in more ‘natural’ ways than existing distributed environments allow. One challenge for global product development is to support true collaboration within global design teams, where diversity and competences of the whole team can be utilized and where team members can think together rather then merely exchange information, opinions and divide work. This paper summarizes the results of several case studies and development projects performed within the Polhem Laboratory over the last four years and proposes challenges for future research. From our findings some of the most important challenges are how to support users with communication tools for more natural formal and informal communication (i.e. as a co-located team communicates), while automatically storing information and context from the distributed meetings.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- There is a need to better understand the organizational factors influencing innovative performance. This cross-cultural study examined organizational support factors in biotech R&D groups differing in innovative performance. The objective was to twofold; first to explore how organizing influences innovativeness in R&D, and, second to examine if R&D organizing is related to nations having a low and high innovation degree, respectively. Results supported that organizing R&D as well as national innovation performance are related. Crucial organizational issues found were how much organizations encouraged innovations, the degree of perceived autonomy and to what extent organizations could supply knowledge. Some of the implications of these results are introduced.
