Spectator View for HoloLens and HoloLens 2


When you're wearing a HoloLens, it's easy to forget a person without one can't experience the same wonders you're seeing. Spectator View lets others see what a HoloLens user sees on a 2D screen. It's also a fast and affordable approach to recording holograms in HD with mobile devices and getting great quality recordings of holograms with video cameras.

Key Resources
