# Mixed reality passthrough window

If you have a compatible VR headset, you can open a passthrough window in an ENGAGE Session. The passthrough window is a rectangular region that shows a view through your headset's passthrough camera. For example, you could position the passthrough window so that you could see and use items on your physical desk, view a computer monitor, or bring the view from your real-world window into your Session.

{% hint style="info" %}
If you use thumb controls to move or teleport in a location, the passthrough window moves with you. If you physically move in your real-world space, the passthrough window remains anchored in place.
{% endhint %}

{% hint style="warning" %}
Only you can see your passthrough window.
{% endhint %}

## Adjusting the passthrough window

* To move or rotate the passthrough window, use the trigger button on either controller to grab the window, and then drag it to a new position.
* To scale the passthrough window, use the trigger button on either controller to grab the window, and then push the right controller's thumbstick up or down.

You can grab any part of the passthrough window.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.engagevr.io/engage/advanced-features/mixed-reality/mixed-reality-passthrough-window.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
