Overview
========

This section explains how to connect [gaze analysis](../gaze_analysis_pipeline/introduction.md) or [augmented reality](../aruco_marker_pipeline/introduction.md) pipelines with various input contexts.

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

![Pipeline input context](../../img/pipeline_input_context.png)

To build your own input context, you need to know:

* [How to define a context class](context_definition.md),
* [How to load a context to connect with a pipeline](configuration_and_connection.md),
* [How to stop a context](stop.md),
* [How to pause and resume a context](pause_and_resume.md),
* [How to visualize a context](visualization.md),
* [How to handle pipeline exceptions](exceptions.md)
