PICO：Controller Tracking Plan Settings

Equipment Used:

  • Pico Series VR Devices

  • UDCAP VR Gloves

Software Used in This Guide:

  • Steam and SteamVR

  • UDCAP Software

  • Pico Official Streaming Assistant (Download from official website)

Important Note: Pico software possesses elevated system privileges. Launching Pico Connect will purge add-ons in SteamVR, potentially causing UDCAP plugin malfunctions or failure of glove-to-controller emulation.

To avoid this, follow these steps strictly.

Manually Install UDCAP Driver into SteamVR:Copy the UDCAP Driver folder (Path: Your Udcap Driver installation directory\udcap) to the SteamVR drivers folder (Path: Your Steam installation directory\Steam\steamapps\common\SteamVR\drivers).

Tip: Repeat this step after every Udcap Driver software update.

1. Launch Pico Connect

Establish a successful stream connection to your Pico headset.

2. Launch Steam via Pico Connect

Initiate Steam through Pico Connect to activate SteamVR.

Note: Pico Connect requests Administrator privileges upon launch.If you launch SteamVR directly via Pico Connect, both Steam and SteamVR will run with Administrator rights.

3. Launch UDCAP Software as Administrator

Administrator Privileges Explanation:

  • Since SteamVR under Pico runs with elevated permissions (forcing Steam into Admin mode), Udcap Driver must also run as Administrator.

  • Ensure consistent privilege levels for Steam, SteamVR, and Udcap Driver.

Starting privileges of different versions of UDCAP

software V0.1.6: If installed on the C drive, this version starts by default with administrator privileges; if installed on other drives, it starts by default with normal privileges.

Between V0.1.3 and V0.1.5: UDCAP software starts by default with administrator privileges.

Before V0.1.3: Starts by default with normal privileges.

4. Verify Plugin Status

In SteamVR Home: Navigate to Settings → Startup/Shutdown → Manage Add-ons and confirm the UDCAP plugin is enabled.

5. Set Controller Priority

In the UDCAP software, set Controller Priority to High to prevent Pico controllers from contending with gloves and ensure glove control takes precedence.

6. Calibration

For calibration procedures, refer to: [Calibration Guidelines]

7. Troubleshooting: Gray Glove Icons

If glove icons remain gray in SteamVR after launching UDCAP software:

  • Manually run udcap_overlay.exe as Administrator (Path: Your Steam installation directory\Steam\steamapps\common\SteamVR\drivers\udcap\bin\win64).

Note: udcap_overlay.exe must match the privilege level of UDCAP, Steam, and SteamVR.

8. Verify Successful Connection

After setup, glove icons in SteamVR Home will appear highlighted, confirming proper connection.

9. Configure Spatial Tracking Solution

In UDCAP Software → Spatial Positioning:
