# Node-based Tracking Workflows

In order to use the values we received through the **Tracking receiver** devices in the *Devices* window, we need to create a **Read** node in one of the layers. So open a layout of one of the layers (by double clicking on it), right-click on a *Layer* window and choose a specific *Layer* reader node.

Every tracking technology is a bit different and the data they provide differs too. However, all of them provide at least *Position and Orientation*.

Therefore, you can always use **Read Tracker** node which works with all tracking technologies.

## Nodes for specific tracking technologies

As most tracking technologies include specific type of format of data, each of these technologies usually have a corresponding layout node that works only with that technology.

In the subsequent pages we will go through some of them.
