Virtual reality and body rotation: 2 flight experiences in comparison

Embodied interfaces, represented by devices that incorporate bodily motion and proprioceptive stimulation, are promising for Virtual Reality (VR) because they can improve immersion and user experience while at the same time reducing simulator sickness compared to more traditional handheld interfaces (e.g.,gamepads). The aim of the study is to evaluate a novel embodied interface called VitruvianVR. The machine is composed of two separate rings that allow its users to bodily rotate onto three different axes. The suitability of the VitruvianVR was tested in a Virtual Reality flight scenario. In order to reach the goal we compared the VitruvianVR to a gamepad using perfomance measures (i.e., accuracy, fails), head movements and position of the body. Furthermore, a series of data coming from questionnaires about sense of presence, user experience, cognitive load, usability and cybersickness was retrieved.
