App should display graphics and respond to head tracking within 4 seconds of launch.
Required - Yes
If your app takes longer than 4 seconds to launch, you must provide a head-tracked loading indicator. Head-tracked means the UI elements must remain stationary in space when the user turns their head. Do not lock any logos or progress indicators to the user’s face.
To test manually:
App begins accepting input, responds to head tracking, and displays graphics within 4 seconds of app startup.
