1. 11. Defining Reality in Virtual Reality: Exploring Visual Appearance and Spatial Experience Focusing on Colour

   Författare :Beata Stahre Wästberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architectural visualization; Virtual Reality; light; colour appearance; Visual appearance; Virtual Environment; simulation; spatial experience;

   Sammanfattning : Today, different actors in the design process have communication difficulties in visualizing and predictinghow the not yet built environment will be experienced. Visually believable virtual environments (VEs) can make it easier for architects, users and clients to participate in the planning process. LÄS MER

3. 12. Virtual Reality for Enriched Rehabilitation of Stroke Patients with Spatial Neglect : Diagnostics and the Rehabilitation Effect on Spatial Attention and Neuronal Activity

   Författare :Helena Fordell; Jan Malm; Anders Eklund; Hanne Krarup Christensen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; spatial neglect; rehabilitation; virtual reality; enriched environment; fMRI;

   Sammanfattning : Background: Approximately a third of all stroke patients develop spatial neglect, a debilitating symptom associated with poor outcome. Spatial neglect is clinically defined as a deficit in processing and responding to stimuli presented on the contralesional side of the body, or the space surrounding that side of the body. LÄS MER

4. 13. Virtual reality exposure therapy for spider phobia

   Författare :Alexander Miloff; Per Carlbring; Lena (Lotta) Reuterskiöld; Nexhmedin Morina; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Specific phobia; spider phobia; spider; fear; anxiety; virtual reality; exposure therapy; automated; alliance; psychometric; factor analysis; virtual therapist; RCT; randomized; non-inferiority; clinical trial; dissemination; 12-month follow-up; Psychology; psykologi;

   Sammanfattning : Exposure therapy for specific phobia involving systematic and repeated presentation of an aversive stimuli or situation is a highly effective treatment for reducing fear and anxiety. Dissemination of this evidence-based treatment has proved challenging, however, and for over 20 years an alternative method of delivery using virtual reality technology has been explored with positive results.

   Sammanfattning : How is virtuality represented in fiction, and what does that say about our anticipations and fears about what the virtual is and will be? This text, a poetics of virtuality, explores fictional representations of virtuality, primarily in movies and literature, but also in media productions done by the author. The aim is to study the dream of virtuality. LÄS MER

7. 15. Virtual worlds and social interaction design

   Författare :Mikael Jakobsson; Erik Stolterman; Ralph Schroeder; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Interaction design; virtual worlds; massively multiplayer online games; internet studies; computer mediated communication; virtual reality; virtual ethnography; human-computer interaction; interacture; social interaction design; Informatics; Informatik;

   Sammanfattning : This dissertation is a study of social interaction in virtual worlds and virtual world design. A virtual world is a synchronous, multi-user system that offers a persistent spatial environment for iconically represented participants. Together, these form an example of social interaction design.
