General remark

• After 1 hour if the helmet is not set properly, it kills your nose.
  • To be properly set the helmet should use inside part of the Hololens to stay on the skull
  • After hours the skulls will hurt... but less that the nose that is pain sensitive

---

To try in the future

• Using HoloLens in a completely dark environment that keeps you from seeing visual cues with your peripheral vision.
