You can control the mouse with your head. Per default it’s off in the desktop viewer, but enabling it is just a single click. If your sim let’s you look around with the mouse that would work. There also is an option to let head tracking act as gamepad axis, but that is usually fairly laggy and not very precise due to how games handle gamepad input. Better than nothing though.
If the sim is based on DX9-11 or an older (‘fixed function’) OpenGL version you might also be able to create an actual 3D profile, although there is no guarantee for that.
