Handtracking#

Hand tracking with Focus 3#

To use Hand tracking with your Focus 3 headset, follow this steps:

  1. Setup your headset (see Quick setup your Focus 3)
  2. Open XR Twin and open your project.
  3. From XR Twin Edition mode:
    1. From the main menu, select Project>Add User... to open the Add User popup,
    2. From the Add User popup, verify that you are using a VR+Hands avatar.
      If not, select VR as the display device, then click on the hand of the silhouette and select Hands as the hand tracking device. Click Add user to scene button to put this avatar to your scene and close the popup.
      Device-VR HandTracking_hand AddUserToSceneButton
    3. Click Start button to launch the simulation.
  4. When in Simulation:
    1. Put on your headset but keep your controllers down and still (on the table).
    2. Watch your hands.
    3. You are now using the Focus 3 hand tracking and can interact with physicalized objects as usual.

How can I teleport ?

If you want to move around, you'll need your controllers from time to time. Take your controllers in hand and use teleport or any other navigation mode to move around the scene. When you've reached the desired position, place your controllers back down again.
A few seconds later, hand tracking resumes.

The same applies to the VR menu tools (to change navigation mode or use one of the VR-tools).

Troubleshootings#

  • Sometimes, when the Focus 3 is in standby mode, hand tracking does not reactivate after Start Simulation mode. In this case, click Stop, wake up the helmet and then click Start again.
  • If the hands are not tracked, from XR Twin Edition mode, verify that the User is VR+Hands.
  • If the helmet does not "move" view (no tracking), verify and/or try the following:
    • SteamVR is the OpenXR Environment. If not, set it so.
    • VIVE Business Streaming is launched in the headset Library (connection is effective). If not, launch again.
    • Reopen VIVE Business Steaming. Sometimes you'll need to restart XR Twin in this case.
  • Hand tracking feature is active by default, but can be enable/disable.
    1. From the VIVE Lobby menu, go to Settings > Inputs
    2. Enable Hand tracking.
  • In SteamVR, from SteamVR menu>Settings>OpenXR>

Hand tracking with Quest#

In order to use the Hand Tracking feature with your Quest headset, these settings need to be made:

  1. From Meta Quest Link>Settings>General, browse to find OpenXR Runtime. Must be set as "Meta Quest Link is set as the active OpenXR Runtime". If not, click SetMeta Quest Link as act... button.
  2. From Meta Quest Link>Settings>Beta, browse to find DeveloperRuntime Features. Must be "on" for Hand tracking. If not, swap it on.
  3. From XR Twin, in Edition mode, switch to a VR+Hands User before clicking Start. In VR-Simulation mode, just put your controllers down (they must be still).

With these settings in mind, you can run through the Quest setup sequence (see Meta Quest quick setup above).

Trackers#

Additional motion capture trackers will be used in 2 situations: with the LS Suit, for simulations capturing body movements (using 5 trackers), and with the Manus gloves, for simulations capturing finger flexions (using 2 trackers):

The LS Suit is compatible with the VIVE headset motion tracking system:

  • If you have a VIVE Pro or Vive Pro2 headset, you can use VIVE Trackers.
  • If you have a VIVE Focus 3, VIVE Vision or VIVE XR Elite headset, you can use VIVE Ultimate Trackers. In this case you'll need a VIVE Wireless Dongle plugged into the helmet to connect the 5 Ultimate Trackers.

The Manus gloves can be tracked with VIVE Trackers 3.0 only.

VIVE Trackers#

vive__14 vive__29

The first time you install your VIVE Trackers 3.0, you will need to pay close attention to ensure that the correct dongles & roles are assigned. We also recommend that you label your trackers. This will help identify the member who is wearing them.Once properly installed and configured, subsequent setups will be quick and easy.

Prerequisites#

Before installing your trackers, there are a few prerequisites:

  • Additional hardware will be available: you will need a USB hub with at least 5 USB type-A ports to plug the 5 VIVE Dongles. Place the 5 VIVE Dongles provided with the VIVE Trackers on the hub, but don't plug the hub to the computer and don't switch on your trackers (you'll do that later).
    vive__29 vive__29 vive__29 vive__29 vive__29 vive__29
  • Your VR headset and controllers must be functional:
    1. The headset is plugged into the PC (you must use an HTC Vive Pro or an HTC Vive Pro2 headset with your Vive trackers 3.0). The Link Box, your Base stations and your Controllers are switched on.
      vive__19
    2. Open SteamVR app. Check that the correct headset, the 2 controllers and the 2 (or more) base stations are detected.
      SteamVR_6
    3. In the SteamVR menu, go to Settings>OpenXR and check that Current OpenXR Runtime is SteamVR.
    4. If not, click on the SET STEAMVR AS OPENXR RUNTIME button (see both images below).

SteamVR_4 SteamVR_5

Set default OpenXR Environment in SteamVR.

At this stage, your equipment is ready for VR simulation in XR Twin (not yet body motion capture).

Recommendations#

We recommend that you stick labels on your trackers so that you can easily identify which member they should be attached to.

Installing your VIVE Tracker#

Pair and assign roles#

  1. As see above, both controllers are paired and connected (there LEDs are green) but the USB hub is not. This is necessary to ensure that the two devices that can be paired with the headset are the controllers.

  2. It's time to plug the USB hub to your computer.

  3. Turn on the first VIVE Tracker and look at the colour of its LED:

    1. If LED turns green, it has already been paired with a dongle.

    2. If LED remains blue, you need to pair it:

      1. From SteamVR's menu icon SteamVR_15select Devices,
      2. Select Pair Controller. Follow the instructions to complete the process.
        The blue LED flashes, then turns green when pairing is complete. A first tracker icon is added in the SteamVR app interface (see image below).
        SteamVR_14

  4. Assign a role to your first tracker:

    1. From SteamVR menu icon SteamVR_15select Devices>Manage Trackers to open the SteamVR Settings popup (alternatively you can right-click on the tracker icon).
    2. In the Controllers tab, on the right find and select MANAGE TRACKERS.
      SteamVR_8
    3. Below Vive Trackers, all trackers are listed. Scroll to find the unique green dot like this SteamVR_13. This is your only tracker turned on.
    4. Just below, on the right of Tracker Role, scroll down the Tracker Role dropdown list and choose the appropriate role (RIGHT ELBOW fir the firs tracker, see tracker number table below).
      SteamVR_10
    5. The first tracker is set.

  5. Repeat the same process for the other 4 trackers, turning on one additional tracker at a time. The roles to be assigned to each tracker are as follows:

Tracker number Role
1 RIGHT ELBOW
2 LEFT ELBOW
3 RIGHT KNEE
4 LEFT KNEE
5 WAIST

poseT5_withnumbers

The position of the trackers relative to the rules in the table.

Once your 5 trackers have been paired, they are connected and displayed in SteamVR (see image below). SteamVR_11



Install is complete!#

At this stage, your body motion capture hardware equipment is installed and ready for full body simulation in XR Twin.

This is a first-time installation only. The dongles associated with each tracker and the roles are saved in SteamVR's configuration files and will be reused identically each time you start up SteamVR. This way subsequent start-ups will be quick and easy.

You can close SteamVR's Settings, then quit SteamVR or continue by starting XR Twin.

Quick Setup for VIVE Trackers#

Connect and power on#
  1. Headset is connected. Power on the Link box and the Base Stations (2 or more).
  2. Open SteamVR.

Update firmware regularly#

Important

Make sure that the trackers that you want to update are turned on and that they are paired with your headset. The status LEDs are green.

  1. In your headset, from the Lobby menu, go to Settings > Inputs > Motion trackers.
  2. Select Firmware update in the lower right.
  3. Select Start update.
Verify that SteamVR is the current OpenXR Runtime#

Why ?

If you always use the same headset, this does not apply to you. On the other hand, if you're using several different devices, it's possible that each will become the current OpenXR Runtime in turn. To use VIVE Ultimate Trackers, check that SteamVR is the current OpenXR runtime.

From SteamVR menu SteamVR_15>Settings>OpenXR, check that SteamVR is still the Current OpenXR Runtime. If not, click the SET STEAMVR AS OPENXR RUNTIME button.
