Gloves with Trackers

This article focuses on streaming MANUS Glove data in combination with HTC Vive Pro or MANUS Pro Tracker data directly to Unreal Engine. This guide does work similarly for other trackers and tracking systems, but the setup might differ.

Make sure to use the latest version of MANUS Core and Unreal Engine 5.0 or higher.

Pairing Trackers

Start SteamVR and pair your Trackers. When using MANUS Pro Trackers please follow the steps described in this article.

Setting up MANUS Core

Note

For detailed instructions on how to set up your exact tracking system, please refer to the tracking system article. The following steps apply to SteamVR compatible trackers.

Settings

Open MANUS Core Dashboard and navigate to Tracking Systems in the Settings Menu.

In Tracking Systems make sure to check OpenVR (SteamVR).

If OpenVR (SteamVR) does not show up here, try and refresh the Tracking Systems by clicking the refresh icon on the top right.

Close the Settings menu.

User Profile

The user profile now shows some extra options, including a list of key joints for your body and which tracker should be assigned to which position.

In this case, we are going to assign our tracker to our left hand.

Click Apply and Close.

This will bring you back to your main screen.

Trackers in the Scene

Under your Gloves section you will now see a Tracker assigned to your hands:

Now go to the Scene view to observe the hands and trackers moving.

Setting up Unreal Engine

Inside your specific hand pawn that you want to have following a tracker (in this case, the Left Hand), go to your Manus Skeleton and open this.

Inside Manus | Map Skeleton Chains, go to Skeleton Chain ID’s > Settings > Hand, and verify that Hand Motion is set to Auto.

Save the Asset (Top left corner, Save icon) and close this window.

Make sure Unreal Engine is connected to the Manus Core host and press Play.

Note

It's not necessary to have MANUS Core connected before pressing Play, but then you'll have to connect manually through code or a blueprint.

This will allow you to move your hand in 3D space, and allow for finger movement.

You should now have hands with hand tracking working in Unreal Engine.
