 The [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) class defines a generic base class interface to handle incoming eye tracker data before to pass them to a processing pipeline according to [Python context manager feature](https://docs.python.org/3/reference/datamodel.html#context-managers). 
 
-The [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) class interface provides playback features to stop or pause processings, performance assement features to measure how many times processings are called and the time spent by the process.
+The [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) class interface provides control features to stop or pause working threads, performance assement features to measure how many times processings are called and the time spent by the process.
 
-Besides, there is also a [LiveProcessingContext](../../../argaze.md/#argaze.ArFeatures.LiveProcessingContext) class that inherits from [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) and that defines an abstract *calibrate* method to write specific device calibration process.
+Besides, there is also a [DataCaptureContext](../../../argaze.md/#argaze.ArFeatures.DataCaptureContext) class that inherits from [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) and that defines an abstract *calibrate* method to write specific device calibration process.
 
-In the same way, there is a [PostProcessingContext](../../../argaze.md/#argaze.ArFeatures.PostProcessingContext) class that inherits from [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext) and that defines abstract *previous* and *next* playback methods to move into record's frames and also defines *duration* and *progression* properties to get information about a record length and processing advancement.

-Finally, a specific eye tracking context can be defined into a Python file by writing a class that inherits either from [ArContext](../../../argaze.md/#argaze.ArFeatures.ArContext), [LiveProcessingContext](../../../argaze.md/#argaze.ArFeatures.LiveProcessingContext) or [PostProcessingContext](../../../argaze.md/#argaze.ArFeatures.PostProcessingContext) class.
