Choosing a VR Headset for an Exhibit

Hello,
I’ve been tasked of making an interactive VR software that will run on a PC directly connected to a headset. The headset will be enclosed in a plastic shell blocking all of its sensors and it will only be able to roate around two axes. I will receive its orientation from an external IMU mounted on the device. I need an advice about which headset to use.
My requirements are:

  • The headset must need no interaction from the user in order to display my application when the system starts
  • The headset must not show any warning about the obscured sensors.
  • The headset must work without any kind of controller.
  • My application will be set as autorun (on Windows)

So… Have you got any suggestion?
Thank you, any help is well appreciated.
