# HMI Marker (Deprecated)

{% hint style="danger" %}
**Deprecated — replaced in realvirtual WEB.** This Unity uGUI marker is deprecated and is **not read by realvirtual WEB**. The browser-based 3D-HMI provides signal-bound status indication through the **WebSensor** component — Low / High / Warning / Error states, ISA-101 colors and a 3D overlay — which exports via `rv_extras` and renders in [**realvirtual WEB**](/extensions/realvirtual-web.md). Use `WebSensor` instead of `HMI Marker` for new work.
{% endhint %}

HMI-Marker are used to visualize the state of a signal. They have to be within the "Worldspace"-Section of a tab.

The current prefab provides a simple cube as a marker object. But it is possible to customize this with a own mesh elements. The structure of the marker includes currently a game object "Icon" to map a user defined icon on the marker object.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.realvirtual.io/components-and-scripts/scene-interaction/hmi-components-pro/hmi-marker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
