Smooth Pursuits

The target does not react when looked at.

First, make sure that you have set the targets up to react to user interaction. Secondly, check if any enviromental challenges are present.


The calibration error starts out low, but slowly increases

This is a case of calibration deterioration, which is normal in all eye tracking systems. See enviromental challenges for possible solutions.

I can't activate the target to start calibration in SPCalibrationViewController

This can be caused by enviromental challenges.

General Performance

I experience severe lag in the UI after navigating from view to view

Make sure that you are breaking retain cycles, and proberly clearing cache once views are released. Check that you have only one instance of SessionManager.
