  Facing the severe global dementia problem, an exploration was conducted
adopting the technology of virtual reality (VR). This report lays a technical
foundation for further research project "Early Detection of Dementia Using
Testing Tools in VR Environment", which illustrates the process of developing a
VR application using Unity 3D software on Oculus Go. This preliminary
exploration is composed of three steps, including 3D virtual scene
construction, VR interaction design and monitoring. The exploration was
recorded to provide basic technical guidance and detailed method for subsequent
research.
