Abstract [en]

Background. When designing video games for Virtual Reality, graphical user interfaces (GUIs) cannot always be designed as they have been for traditional video games. An often recommended approach is to merge the interface with the game world, but it is unclear if this is the best idea in all cases. As the market for Virtual Reality is growing quickly, more research is needed to create an understanding of how GUIs should be designed for Virtual Reality.

Objectives. The thesis researches existing GUI type classifications and adapts them for VR. A method to compare the GUI types to each other is selected and conclusions are drawn about how they affect player performance, usability, and preference. 

Methods. A VR FPS game is developed and an experiment is designed using it. The experiment tests the player's performance with each of three distinct GUI types and also presents questionnaires to get their personal preference.

Results. Both player performance and subjective opinion seems to favour geometric GUI.

Conclusions. The often recommended approach for designing GUI elements as part of the game world may not always be the best option, as it may sacrifice usability and performance for immersion.

Abstract [sv]

Bakgrund. Vid design av grafiska användargränssnitt (GUI) till Virtual Reality kan inte alltid samma design användas som tidigare har använts i traditionella TV-spel. Ett tillvägagångssätt som ofta rekommenderas är att göra spelets GUI en del av spelvärlden men det är oklart om det är den bästa strategin när man väger in prestation, användbarhet, och preferens. Eftersom marknaden för Virtual Reality växer snabbt behövs mer forskning för att få en förståelse för hur grafiska användargränssnitt bör designas.

Syfte. Detta examensarbete undersöker existerande klassifikationer av GUI:n och anpassar dem för VR. En metod för att jämföra de olika typerna av GUI väljs ut och slutsatser dras om hur de påverkar prestanda, användbarhet och preferens.

Metod. Ett VR FPS-spel utvecklas och ett experiment designas baserat på det. Experimentet testar spelares prestanda med tre olika typer av GUI. Spelarna svarar även på enkäter om upplevd användbarhet och preferens.

Resultat. Data från både prestanda och personlig preferens verkar förespråka Geometriskt GUI.

Slutsatser. Metoden som ofta rekommenderas där spelets GUI arbetas in som en del av spelvärlden verkar inte alltid vara det bästa valet då det kan offra användbarhet och prestanda för inlevelse.
