ROVER is a Virtual Reality / VR questionnaire toolkit to enable researchers with a limited IT background to easily integrate immersive rating scales and questionnaires into their VR user experience studies.
ROVER uses the SteamVR Overlay Interface together with the OpenVR Compositor Interface to project 2D content over the 3D Virtual Environment.
ROVER has been evaluated as part of a user experience pilot study in collaboration with health psychologists.
The research paper introducing the tool is open access and can be found here: https://dl.acm.org/doi/10.1145/3660515.3661328. Other research using ROVER is listed below.
