Prototyping VR Training Tools for Healthcare With Off-the-Shelf CGI

Cloud computing, big data, wearables, the internet of things, artificial intelligence, robotics, and virtual reality (VR), when seamlessly combined, will create the healthcare of the future. In the presented study, the authors aim to provide tools and methodologies to efficiently create 3D virtual learning environments (VLEs) to immerse participants in 3600, six degrees of freedom (6DoF) patient examination simulations. Furthermore, the authors will discuss specific methods and features to improve visual realism in VR, such as post-processing effects (ambient occlusion, bloom, depth of field, anti-aliasing), texturing (normal maps, transparent, and reflective materials), and realistic lighting (spotlights and custom lights). The presented VLE creation techniques will be used as a testbed for medical simulation, created using the Unity game engine.
