## Summary

Augmented Reality (AR) systems provide users with timely access to everyday information. Designing how AR messages are presented to the user, however, is challenging. If a visual message is presented suddenly in users’ field of view, it will be noticed easily, but might be disruptive to users. Conversely, if messages are made visible by slowly fading their opacity, for example, they might require more effort for users to notice and react, as they need to wait for the content to appear. This is particularly true for head-anchored virtual content, and when users are engaged in other tasks or walking in a physical environment. To address this challenge, we introduce a motion-aware technique that delivers AR visual information unobtrusively during walking when users rotate their head. When users make a turn, TurnAware moves the visual content into their field of view from the side at a speed proportional to their rotational velocity.

## 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://library.xrguild.org/current-peer-reviewed-immersive-technologies/turnaware-motion-aware-augmented-reality-information-delivery-while-walking.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.
