Program a button to change levels when in Oculus VR Mode

I am working on a building science model of a space that will allow a user to evaluate the space in Oculus VR, I am currently trying to program a button click so that I can use a remote or controller to make the model change levels. This will allow the viewer to have different vatange points to evaluate the space. I’m not trying to use the teleport and I cant use a box trigger because I cant have the player physically move in the model due to the possibility of motion sickness.
