Spectator View for HoloLens and HoloLens 2

Marker

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

Use Cases

  • You can record a mixed reality experience using an iPhone or Android device. Record in full HD and apply anti-aliasing to holograms and shadow for a cost-effective and quick way to capture video of holograms.
  • Stream live mixed reality experiences to an Apple TV directly from your iPhone or iPad, lag-free!
  • Share the experience with guests: Let non-HoloLens users experience holograms directly from their phones or tablets.

Current Features

  • iOS (ARKit-enabled devices) and Android (ARCore-enabled devices) support. Multiple iOS guests. Recording of video + holograms + ambient sound + hologram sound. Share sheet so you can save video, email it, or share with other supporting apps.
