public enum ARTrackingFailureReason

Object
Enum<ARTrackingFailureReason>
ARTrackingFailureReason

ImplementsComparable<ARTrackingFailureReason>

Why an ARSession reports ARTrackingState#LIMITED or ARTrackingState#NOT_TRACKING. Useful for prompting the user, for example to move the device more slowly or to point it at a textured surface.

Enum constants

`NONE`	Tracking is not degraded.
`INITIALIZING`	The session is still gathering its first observations; tracking quality improves as the user moves the device.
`EXCESSIVE_MOTION`	The device is moving too fast for reliable tracking.
`INSUFFICIENT_LIGHT`	The scene is too dark for the camera to track features.
`INSUFFICIENT_FEATURES`	The camera sees too few visual features, for example a blank wall.
