- Throughout the design of a new building it is essential that all involved stakeholders understand, communicate, participate, and collaborate with each other to acquire a high-quality result. To support these shared and creative design processes, this paper presents the design and evaluation of virtual collaborative design environment (ViCoDE) - a new collaborative design system. ViCoDE features seamless integration of several immersive VR systems and a multitouch table that facilitates collaborative and interactive design work with immediate feedback. The evaluation of the system has been done during two real-life collaborative design workshops in a context of designing new healthcare environments. The results show that the VR system and multitouch table complement each other very well by facilitating both collaborative, and individual design spaces - and that it fosters better understanding, participation, communication, knowledge sharing, and collaboration among the different stakeholders. The contribution is two-fold: presentation of a new collaborative design system and the evaluation of its use in a real-life design context, which demonstrate how these new technology-based workshops may facilitate design management.

- Adult foreign language acquisition is challenging, and the degree of success varies among individuals. Anatomical differences in brain structure prior to training can partly explain why some learn more than others. We followed a sample of conscript interpreters undergoing intense language training to study learning-related changes in white-matter microstructure (FA, MD, RD and AD) and associations between differences in brain structure prior to training with acquired language proficiency. No evidence for changes in white matter microstructure relative to a control group was found. Starting values of RD, AD and MD were positively related to final test scores of language proficiency, corroborating earlier findings in the field and highlighting the need for further study of how initial brain structure influences and interacts with learning outcomes.

Demystifying the Black Box - Exploring How Users Make Sense of Fully Automated Vehicles
- 2020

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Vehicles are becoming increasingly automated. Already today vehicles are able to take over and assist the human driver in certain driving tasks, and the scope of technical possibilities is rapidly expanding. However, for the proliferation of AVs to occur, there are several challenges that must first be overcome. These challenges are not only structural, including regulations and technological development, but also user-related, such as the adoption of and willingness of users to use the system. Previous research has identified the importance of user understanding of Automated Vehicles (AVs), as this affects usage directly as well as indirectly by impacting acceptance. In this thesis, a design approach has been chosen that uses a product semantic framework as the basis for addressing the issue of user understanding with the aim of exploring how users make sense of the AV. The research presented is based on data from a quasi-experimental study, conducted using a seemingly fully automated (WOz) vehicle on a test course where participants’ understanding was investigated both during and after the test runs. The findings show that use of the AV gave rise to several levels of meaning, based on two different processes. The main one was an external process, where integration of the participants’ conceptual models of human drivers and AVs, artefactual signifiers, and situational signifiers in a context developed meaning. However, an internal process was also evident, where meanings themselves developed new meanings. This thesis presents a tentative model based on the findings, describing three important components: the user’s conceptual model, the signifiers, and the meanings that arise during usage of the AV. The model illustrates the complex interplay between these three components and can be used to better understand and investigate how users make sense of AVs to aid the design and development of AVs. The thesis also contributes to the field of product semantics through the practical application of product semantic theories, in addition to providing further insight into how users develop meaning and make sense of artefacts, by describing the processes and components which seem to be the foundation when making sense of artefacts. Having said that, further studies need to explore in greater detail the dynamics of the process of making sense, the process of making sense in partially automated vehicles, and how meaning changes during a prolonged usage.
