# FAQ: Augmented Reality

### What is AR? <a href="#can-i-scan-transparent-objects" id="can-i-scan-transparent-objects"></a>

AR stands for Augmented Reality. It is a technology that aims to overlay spatially tracked computer generated data over your view of the real world via the use of displays in a headset, in front of your eyes.&#x20;

The computer generated images are overlaid onto a transparent glass that lets you see your real environment while also showing you the computer generated data. This allows the images visible to you to be changing in real time as you move your head. Cameras on the HoloLens track and analyse predetermined gestures of your hands to control the device's menu.

### Where can I try AR? <a href="#can-i-scan-transparent-objects-1" id="can-i-scan-transparent-objects-1"></a>

You can book an introduction session at the NExT Lab:

### What AR gear is available at University? Can it be loaned out? <a href="#what-vr-gear-is-available-at-university-can-it-be-loaned-out" id="what-vr-gear-is-available-at-university-can-it-be-loaned-out"></a>

We have several **Microsoft HoLoLens Headsets** available. **University of Melbourne students and staff** are able to [ loan this equipment from the MSD Print Room and Loans Desk](https://msdunimelb.simplybook.me/v2/#book/location/1/category/46/) and be used in any spare teaching space in the building.

You will need to [book an introduction session first](https://msdunimelb.simplybook.me/v2/#book/location/2/category/23/service/146/) **before loaning out this equipment**.

Most **mobile phones** can also be used for Augmented Reality development. See: [Mobile (Augmented Reality Platforms)](https://msd-makerspaces.gitbook.io/next-lab/~/edit/drafts/-LY9jbQy1U7xHUWiX_Wl/augmented-reality/platforms-hardware/mobile)

### What things can I do with AR? <a href="#what-things-can-i-do-with-vr" id="what-things-can-i-do-with-vr"></a>

HoloLens comes pre-installed with an AR demo that lets you place a variety of 3D objects as holograms into the real world and allows you to walk around and inspect the holograms from all sides.

Additionally via the use of the software package Fologram you can use HoloLens to display geometries generated in Rhino. In conjunction with the use of Grasshopper, these geometries can be manipulated via gestures and pointers in HoloLens itself.

You can also develop mobile applications using software packages such as [Vuforia and Unity](/next-lab/augmented-reality/resources/unity-and-vuforia.md).

### What are the requirements for a computer to run AR? <a href="#what-are-the-requirements-for-a-computer-to-run-vr" id="what-are-the-requirements-for-a-computer-to-run-vr"></a>

HoLoLens is a standalone computer and as such can be used to do the demo. However an additional computer/laptop is needed to run Rhino and Fologram.&#x20;

### I'm having trouble getting the AR headset to work. What can I do? <a href="#im-having-trouble-getting-the-vr-headset-to-work-what-can-i-do" id="im-having-trouble-getting-the-vr-headset-to-work-what-can-i-do"></a>

HoLoLens works by locating itself in the space via it's suite of camera/sensors. These sensors can be thrown off by mirrored surfaces as well as direct-facing sunlight. As much as possible try to cover mirrored surface finishes as well as pull down blinds in the room you are using.&#x20;

Additionally there are some difficulties with having several HoLoLens connected on the same network. For ways to solve this and more issues please check out our troubleshooting page at:

## 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://ms-kb.msd.unimelb.edu.au/next-lab/augmented-reality/troubleshooting/faq-augmented-reality.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.
