The short version

  • Only Unity AR Foundation has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft HoloLens 2 narrow field of view of 52 degrees limits visibility of holograms and causes parts of 3D objects to disappear when viewing up close; Unity AR Foundation requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • They diverge on capability: Microsoft HoloLens 2 covers Spatial mapping, Unity AR Foundation covers Plane detection.

Microsoft HoloLens 2

  • Narrow field of view of 52 degrees limits visibility of holograms and causes parts of 3D objects to disappear when viewing up close
  • Heavy weight makes extended wearing uncomfortable and impractical for sessions longer than a few hours
  • Short battery life of 2.5 to 5.5 hours limits extended deployments without charging
  • Display is sensitive to bright light and sunlight, with rainbow color artifacts and poor outdoor readability
  • High price of $3,500 limits accessibility to enterprises with substantial budgets

Unity AR Foundation

  • Requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • Performance varies significantly by device, with battery drain and heat generation on mobile
  • Emulators cannot accurately test AR experiences due to missing camera and sensor data
  • No WebXR support for browser-based AR experiences
  • Occlusion features show lower performance at 25-40 FPS compared to other features at 40-60 FPS
  • Limited access to latest platform-specific features compared to native ARKit or ARCore
