[![Simlab_VRSmall.png](https://simlab-soft.com/help/uploads/images/gallery/2025-09/scaled-1680-/simlab-vrsmall.png)](https://simlab-soft.com/help/uploads/images/gallery/2025-09/simlab-vrsmall.png) This chapter guides you through installing the **SimLab VR Viewer** on your Pico Device. SimLab VR Viewer is a free, essential cross-platform application required to run, view, and participate in VR experiences, including collaboration sessions and viewing shared SimLab VR packages (.vrpackage files).
**Installation Method: Via Installation Manager (PC/Mac & Cable)** 1. **Request Access:** Go to the official [SimLab Pico VR page.](https://www.simlab-soft.com/technologies/simlab-pico.aspx) 2. **Get Installer:** Click the **"Get it Now"** button, fill in your information (Name, Email, Industry), and you will be directed to the download page. Download the **SimLab VR Viewer Installation Manager for Pico VR** for your operating system (Windows or macOS). 3. **Configure Headset for Sideloading (One-Time Setup):** - Put on the Pico headset. - Go to **Settings > Advanced Settings >** and enable **Allow unknown apps**. - Enable Developer Mode (if not already enabled, usually by clicking the **PUI Version** multiple times in **System > About Device**). - Go to **Settings > Advanced Settings > Developer options >** and enable **USB debugging**. 4. **Connect Headset:** Connect your Pico headset to the PC or Mac using a USB-C cable. 5. **Allow Debugging:** Put on the headset, wait for the confirmation message, and **Allow the USB Debugging** prompt to establish a connection. 6. **Install App:** Run the downloaded **Installation Manager** on your computer. Click the **(Install)** button within the manager to sideload the VR Viewer application onto your Pico VR device. 7. **Locate App:** After installation is complete, find and launch the app on your Pico VR headset by navigating to the appropriate section for sideloaded or unknown sources applications (typically found in the **Library** or **All Apps** section under a filter like **Unknown source**).

In your Pico VR headset, launch the **SimLab VR Viewer** application. 2. Select **Sign In** and use your Pico controllers to enter your **SimLab account email and password**. # Joining as a contact This is the simplest way to join. If the host/administrator has already added your email to their SimLab **Contacts** list (managed in the **SimLab Dashboard**), you don't need a link. **Prerequisites:** - The host must have added your email to their SimLab **Contacts** list. - You must be **Signed In** to the SimLab VR Viewer app on your Pico VR headset. #### Joining via In-App Notification Because you are an invited contact, the SimLab VR Viewer will handle the invitation entirely inside your headset. **Action (In-App Join):** 1. **Notification Prompts:** When you are inside the SimLab VR Viewer, you may see timed messages leading up to the scheduled start time. 2. **Host Initiates Session:** When the host clicks **Start Collaboration**, you will receive the final launch prompt directly inside your headset. - *Message:* "\[Host Name\] has invited you to join a Collaborative VR Experience session." 3. **Click the 'Join' Button:** Use your Pico controller to click the **Join** button within the notification window to immediately launch and enter the collaborative VR session **Lobby**.

Since the Pico VR browser does not easily launch VR apps from web links, you must first register the link using a helper device or manually enter the URL. **Prerequisites:** - The host sends you the invitation link via email or chat. - You must access the link on a **PC or mobile device** (Method A) or manually type it in VR (Method B). #### Method A: Registering the Link to Your Account (Recommended) Use a PC or mobile device to register the link, which converts the invitation into a registered session, allowing the Pico headset to treat you as an invited contact.

On the web page that opens, click the **Add to Calendar** or **Add Link** button. 3. **Log In:** If prompted, log into your **SimLab account**. 4. The session is now registered in the **Invitations** tab on the **SimLab Dashboard**. **Joining the Session (in Pico VR Headset):** 1. Put on your **Pico VR Headset** and launch the **SimLab VR Viewer** while logged into the same account. 2. Because the session is registered to your account, when the host starts the session, you will receive the **in-app notification** (as described on Page 2). 3. Click **Join** to enter the **Lobby**.

Launch the **SimLab VR Viewer** application. 2. Locate and click the **URL Launcher** button (often a small icon or button). 3. Use the VR keyboard to **type or paste the Invitation Link** into the dialogue window. 4. Click **Confirm**.
