Overview
========

This section explains how to process incoming gaze positions through a **gaze analysis pipeline**. 

!!! warning "Read eye tracking context section before"
	This section assumes that the incoming gaze positions are provided by an [eye tracking context](../eye_tracking_context/introduction.md).

First, let's look at the schema below: it gives an overview of the main notions involved in the following chapters.

![Gaze analysis pipeline](../../img/gaze_analysis_pipeline.png)

To build your own gaze analysis pipeline, you need to know:

* [How to edit and execute a pipeline](configuration_and_execution.md),
* [How to describe AOI](aoi_2d_description.md),
* [How to enable AOI analysis](aoi_analysis.md),
* [How to visualize pipeline steps outputs](visualization.md),
* [How to record resulted gaze analysis](recording.md),
* [How to make heatmap image](heatmap.md),
* [How to add a background image](background.md).

More advanced features are also explained like:

* [How to edit timestamped gaze positions](advanced_topics/timestamped_gaze_positions_edition.md),
* [How to script gaze analysis pipeline](advanced_topics/scripting.md),
* [How to load module from another package](advanced_topics/module_loading.md).
* [How to calibrate gaze position](advanced_topics/gaze_position_calibration.md).
