Abstract (Swedish)
Mer än 10% av Sveriges befolkning lider av någon fobi och detta projekt studerar möjligheten att lindra akrofobi (höjdskräck) med hjälp av virtual reality (VR). Arbetets syfte är därför att undersöka hur man på bästa sätt kan lindra akrofobi med hjälp av VR. Frågeställningarna som skulle besvaras var: ”Kan man med hjälp av enbart visuell och auditiv feedback skapa en trovärdig miljö för att lindra akrofobi?” och ”Gör det någon skillnad om försökspersonen utför uppgifter i den virtuella miljön jämfört med att inte göra det underbehandlingen?”. Två versioner av en VR-prototyp har utvecklats för att undersöka bästa möjliga metod. Prototyperna togs fram genom en iterativ designprocess. Skillnaden mellan versionerna var huruvida man... (More)

Två versioner av en VR-prototyp har utvecklats för att undersöka bästa möjliga metod. Prototyperna togs fram genom en iterativ designprocess. Skillnaden mellan versionerna var huruvida man interagerade med olika virtuella objekt eller inte under behandlingen. Prototyperna jämfördes med användbarhetstestning på 22 försökspersoner varav fyra var höjdrädda.

Utifrån de resultat som togs fram visade det sig att det var fullt möjligt att skapa en miljö som frambringar en känsla av höjd, vilket är väsentligt för att kunna lindra akrofobi. Det visade sig även att utföra uppgifter gav mervärde. Dock hade båda prototyperna olika styrkor och en kombination av de två prototyperna hade antagligen varit den bästa lösningen för att kunna lindra akrofobi. (Less)
Abstract
More than 10% of Sweden's population suffers from some kind of phobia and this project is studying ways to ease acrophobia (fear of heights) with virtual reality (VR). Therefore, the purpose of the work was to investigate how to best ease acrophobia with help of VR. The research questions to be answered were: "Is it possible with just visual and auditory feedback to create a credible environment to cure acrophobia?" and "Does it make any difference if the person performs tasks in the virtual environment compared to not doing it during treatment?". Two versions of a VR prototype were evolved to investigate the best possible method. The prototypes were developed through an iterative design process. The difference between the versions was...

More than 10% of Sweden's population suffers from some kind of phobia and this project is studying ways to ease acrophobia (fear of heights) with virtual reality (VR). Therefore, the purpose of the work was to investigate how to best ease acrophobia with help of VR. The research questions to be answered were: "Is it possible with just visual and auditory feedback to create a credible environment to cure acrophobia?" and "Does it make any difference if the person performs tasks in the virtual environment compared to not doing it during treatment?". Two versions of a VR prototype were evolved to investigate the best possible method. The prototypes were developed through an iterative design process. The difference between the versions was whether they interacted with different virtual objects or not during the treatment. The prototypes were compared to each other in usability testing with 22 persons, where four had a fear of heights.

Based on the results from the comparison testing, it was found that it was entirely possible to create an environment that produces a sense of height, which is essential to ease acrophobia. It was also found that performing tasks during treatment added value. However, both prototypes had different strengths and a combination of the two prototypes would probably have been the best solution to cure acrophobia. (Less)
