Bokkapitel (refereegranskat)abstract
- This paper reports the results of a test involving twelve users of different haptic audio navigational tools for non-visual virtual environments. Analysis of the test results confirms the usefulness of a constant attractive force as well as of haptic fixtures to help users locate objects in a virtual environment. The 3D audio turned out to be less useful due to the design of the environment. However, user comments indicate that this type of sound feedback helps spatial understanding. Contrary to expectations, no significant tool effects were seen on spatial memory.

Konferensbidrag (refereegranskat)abstract
- Haptic feedback in shared virtual environments can potentially make it easier for a visit ally impaired person to take part in and contribute to the process of group work. In this paper a task driven explorative evaluation is presented. of collaboration between visually impaired and sighted persons in three applications that provide haptic and visual feedback. The results show that all pairs could perform all the tasks in these applications even though a number of difficulties were identified. The conclusions made can inform design of applications for cooperation between visually impaired and sighted users.

Tidskriftsartikel (refereegranskat)abstract
- This paper presents a study of cross-modal collaboration, where blind and sighted persons collaboratively solve two different tasks using a prototype that has one auditory and one graphical interface. The results shows the importance of context and the design of tasks for the accessibility of cross-modal collaborative settings, as well as the importance of supporting the participation in a working division of labour.
