# NIAlgorithmConvergenceStatusNotConverged

A status that indicates the framework’s Camera Assistance feature requires action from the user.

## Declaration

```occ
NIAlgorithmConvergenceStatusNotConverged
```

## Discussion

Discussion In this state, the framework needs more information about the user’s physical environment before setting horizontalAngle and/or verticalDirectionEstimate. Look to the reasons array of the convergence object provided by  session(_:didUpdateAlgorithmConvergence:for:) for more information on the cause. Each reason indicates a specific action the user can do to provide ARKit with the necessary camera data to support Nearby Interaction’s Camera Assistance.
