This study examines the effects of a unified user interface with a hybrid 2D/3D design on user interaction experience in virtual reality, compared with a splintered user interface with mixed 2D and 3D elements. The purpose is to gain an understanding of the differences in usability between splintered and unified user interfaces in virtual reality. This is achieved through designing and implementing a unified user interface based on previous research into VR user interface design, and conducting user tests comparing it with an existing, splintered VR user interface. User performance in and experience of said interfaces is then compared and analyzed.
