Both applications of Simubat 4.0 Gen-2, are developed using the Unity3D VR/AR/game engine and deployed on the devices. The first one runs a configurable simulation written in C# language, plus some XR plugins and interaction libraries ; while the MR app manages the storage of the 3D-resolved electrode microstructures and use the on-board camera to detect QR-codes and match which electrode microstructure to display; it then allows manipulation using the HoloLens MRTK framework and C# custom code.
