The updated application features a tutorial, an improved archery range experience, and two new experiences: a drawing experience and a virtual spacewalk. Usability and performance testing showed that the new version is more stable, user-friendly, and visually accurate than its predecessors. While some usability issues and bugs remain, the application runs faster, and it should have a reduced incidence of nausea among users. Overall, the new version of DeltaVR offers a better experience with further scope for improvements.engopenAccessAttribution-NonCommercial-NoDerivatives 4.0 InternationalComputer GraphicsVirtual RealityUnityUser TestingGame DesignSoftware DevelopmentmagistritöödinformaatikainfotehnoloogiainformaticsinfotechnologyThesis
