The current version of Mugi Sim supports both Oculus Rift and HTC Vive from the same program file. This screenshot shows the virtual reality version of the menu with “floating” canvas and buttons. VR controller models have been drawn to represent the hands.
The current work in progress menus allow you to point at the buttons with the VR controllers. Once the bounding boxes of the buttons are entered, you can use the select button or pull the trigger to move through the menus. I prefer this style to the menus where you have to walk toward and either “grab” or “punch” the buttons.
