This cursor follows our gaze as we look around the scene in virtual reality. Lastly, we also used our gaze to shoot a ray at Ethan, causing him to lose health and eventually explode.

User interface (UI) conventions found in desktop applications and video games may not work well in VR, because they operate in Screen Space.
