# Platforms & Devices

> Where Altoura Frontline runs today — supported head-mounted displays, tablets, web browsers, and Microsoft Teams clients.

Altoura Frontline is designed to meet frontline workers on the device that fits the job — from a hands-free head-mounted display on the factory floor to a tablet in a service van to a browser on an author's laptop. This page lists the platforms we support today and what each one is used for.

## HoloLens 2 — the primary frontline device

HoloLens 2 is the main supported head-mounted display for Altoura Frontline. Workers use it to run procedures and join Remote Expert sessions fully hands-free.

  <Card title="Install & Sign In" icon="download" href="/frontline/hololens/get-started/install-and-sign-in">
    Install Altoura Frontline from the Microsoft Store on HoloLens 2, then sign in with email & password, SSO, or PIN pairing.
  </Card>

    A 10-minute guided first run on the device.
  </Card>
</CardGroup>

### Device requirements

* **Device:** Microsoft HoloLens 2
* **OS:** Latest Windows Holographic update
* **Account:** Microsoft account signed in on the device
* **Network:** Wi-Fi with internet access and HTTPS reach to Altoura backend
* **Tenant access:** Your IT administrator has enabled Altoura Frontline for your organization

### What you can do on HoloLens 2

* Run published procedures in Operator Mode with AR-anchored steps and 3D guidance.
* Author procedures directly on-device in Author Mode.
* Start a Remote Expert session from the **Contacts** tab or join a scheduled **Teams Meeting**.
* Use the **Hand Menu** (palm-up gesture) during Remote Expert calls for mute, reposition, spatial-mesh toggle, and exit.
* Receive live annotations, PDFs, and 3D models from the expert's Teams panel.

## iPad — coming soon

<Note>
  Full Altoura Frontline documentation for iPad is in progress. See the [iPad tab](/frontline/ipad/index) for what's planned.
</Note>

The iPad experience brings Altoura Frontline to a handheld form factor for field workers, supervisors, and roles where a head-mounted display isn't practical. Planned capabilities include:

* Installation and organizational sign-in on iPad.
* Opening and running procedures authored for iPad.
* Joining Microsoft Teams Remote Expert calls from iPad.
* Managing preferences, account, and offline content from the device.

Until iPad is fully available, the [HoloLens documentation](/frontline/overview/welcome) covers the core concepts — procedures, steps, Remote Expert, and administration — most of which apply directly.

***

## Procedures Portal — web authoring

The **Procedures Portal** is the browser-based companion to Altoura Frontline. It gives authors and supervisors a desktop workspace for creating, organizing, and publishing the procedures that field workers run on their HMD or tablet.

### Used for

* Building new procedures from scratch (tasks, steps, media, 3D objects).
* Editing and reordering existing procedures at scale.
* Managing the asset library (3D models, images, videos).
* Publishing procedures to HoloLens and iPad apps.
* Role management for authors, operators, and experts.
* Reviewing audit logs to see who changed what.

### Typical use cases

* A training team authoring a new machine changeover procedure from the office.
* A supervisor updating the step order on a maintenance procedure without touching the headset.
* An administrator reassigning procedure ownership between teams.

See the [Procedures Portal overview](/frontline/procedures-portal/landing-page) for the roadmap of portal documentation.

## Microsoft Teams — the expert's home

Experts don't need to install the Altoura client app. They work from the **Microsoft Teams client** (desktop or web) they already have, using the **Altoura Remote Expert** meeting extension.

<CardGroup cols={2}>
  <Card title="Verify the Teams app" icon="circle-check" href="/frontline/remote-expert/verify-teams-app">
    Confirm the app is deployed to your tenant and add it to your Teams client before your first call.
  </Card>

  <Card title="Add the app to a meeting" icon="puzzle-piece" href="/frontline/remote-expert/add-teams-app">
    Drop the app into any live Remote Expert meeting to unlock annotations and sharing.
  </Card>
</CardGroup>

### Teams requirements

* **Microsoft 365** tenant with Teams licenses for all participating users.
* **Entra ID** (Azure AD) tenant.
* **Teams Admin Center** access for the IT administrator deploying the app.
* **Network allowlist:** HTTPS access to `altouraremoteacs.azurewebsites.net` from the expert's client.

### What the expert can do in Teams

* Receive an Adaptive Card invitation in Teams chat and join with one click.
* Join a scheduled Teams meeting that the worker is also joining from HoloLens.
* Open the **Altoura Remote Expert** side panel in the meeting.
* Start and stop annotation mode to draw on the worker's live view.
* Share PDFs and `.glb` 3D models with the HoloLens user.

For the full enterprise-rollout procedure, see the [Remote Expert IT Admin Guide](/frontline/administration/remote-expert-it-admin/overview-and-prerequisites).

## Altoura Portal — administration & pairing

The Altoura Portal (at `procedure.altoura.com`) is used alongside the HMD app to:

* **Pair HoloLens devices** using the PIN flow — the HMD shows a 6-digit code, you enter it on the portal, and the device is signed in without typing credentials on the headset.
* **Manage tenant configuration** and user assignments.
* **Review deployed content** available to operators.

See [Install & Sign In → PIN Pairing](/frontline/hololens/get-started/install-and-sign-in#method-3-pin-pairing) for the end-to-end pairing walkthrough.

***

## Network & connectivity requirements

At a minimum, every Altoura Frontline deployment needs the following reachable over HTTPS (443):

| URL                                   | Purpose                                                                  |
| ------------------------------------- | ------------------------------------------------------------------------ |
| `altouraremoteacs.azurewebsites.net`  | Remote Expert app host, backend API, meeting tab, side panel, stage view |
| Altoura content CDN and API endpoints | Procedure content delivery, authentication, telemetry                    |

If your organization uses a firewall or proxy, add these to your HTTPS allowlist. See [Network Configuration & Credentials](/frontline/administration/remote-expert-it-admin/overview-and-prerequisites) for details.
