Conference paper (peer-reviewed)abstract
- This paper focuses on presenting a technological framework for supporting knowledge sharing in organizations through computer support. The framework is based on the results from three studies of organizational knowledge in three kinds of settings and focuses on communication between people, awareness information about people's activities and availability, and information management. The third study also included an evaluation of a number of prototypes developed based on the three areas focused on in the framework. The results from the evaluation indicate that the framework is suitable for the purpose of supporting knowledge exchange.

Procuring a usable system using unemployed personas

Conference paper (peer-reviewed)abstract
- This case study examines a procurement project where the Swedish National Labor Market Administration (AMV) hired usability consultants in order to redesign their website for employment exchange. The user centered design process was part of a larger project to define how the website could be reorganized to better support new organizational goals. The project was managed by a procurement group that had already defined the organizational requirements for the website. They hired the usability consultants to learn about user requirements and to specify an information architecture and design. The usability company suggested a process with a user research phase and an iterative design phase. The primary deliverables would be personas and an evaluated prototype. The results demonstrate how the user centered design process can effectively be used by active procuring organizations as a bridge between abstract organizational requirements and concrete systems requirements. Tools such as personas and prototypes helped the procurers to understand and prioritize among requirements, as well as to communicate their work to the organization. These tools will be used in the continued work to specify and develop the system.

Navigating in virtual environments using a vision-based interface
- 2004

In: Proceedings of the third Nordic conference on Human-computer interaction. - New York, NY, USA : ACM. - 1581138571 - 9781581138573 ; , s. 113-120

Conference paper (peer-reviewed)abstract
- Interacting and navigating virtual environments usually requires a wired interface, game console, or keyboard. The advent of perceptual interface techniques allows a new option: the passive and untethered sensing of users’ pose and gesture to allow them to maneuver through and manipulate virtual worlds. We describe new algorithms for interacting with 3-D environments using real-time articulated body tracking with standard cameras and personal computers. Our method is based on rigid stereo-motion estimation algorithms and can accurately track upper body pose in real-time. With our tracking system users can navigate virtual environments using 3-D gesture and body poses. We analyze the space of possible perceptual interface abstractions for full-body navigation, and present a prototype system based on these results. We finally describe an initial evaluation of our prototype system with users guiding avatars through a series of 3-D virtual game worlds.

Making a difference : a survey of the usability profession in Sweden
- 2004
-
In: Proceedings of the third Nordic conference on Human-computer interaction. - New York : ACM Press. - 1581138571 ; , s. 207-215
-
Conference paper (peer-reviewed)abstract
- Poor usability in interactive systems/products is still a major problem for users and buyers, despite efforts made by an increasing number of usability professionals. How come this is so and what are the main obstacles to usability work? In this paper we report the results of a survey of usability professionals in Sweden, conducted in 2003. The survey identified, e.g. their background and experiences, the type of employment, organization, and products/systems, the software development process being used and some key success factors for usability work. The results indicate, among other things, that management support and project management support are essential for the usability worker. Moreover, they face problems such as, usability and user involvement having low priority in the projects.
