Users

alt text

Users are the Subjects or Actors of the MANUS ecosystem. A User represents a single person, wearing gloves, trackers or both. The system is used in our plugins to keep track of what devices belong to what user. The system is also used in our recorder to export data per user.

Profiles

The profiles menu lists all users.

User

The eye allows you to hide all the user's devices from the viewport. Profile settings brings you to the window where you can configure the user. The Calibrate button will start the calibration proces for the gloves and or trackers.

Add user

The Add User button will start the user creation wizard again and guide you through the process of creating a user and pairing and calibrating devices.

Unassigned items

The unassigned items list will show all devices currently not assigned to a user. MANUS Core will also throw notifications to remind you of this fact. It's generally recommended to always have your devices assigned to a user.

Ordering

alt text

The order of the users can be relevant for some setups. The dots in front of the user allow you to drag and change the order of users.

Profile settings

alt text

The profile settings panel lets you configure the user.

Name

The name field allows you to change the name of the current user. Changing the name does not change the UserID (the unique identifier used to identify this specific User).

Remove profile

This deletes the current profile.

Gloves

alt text

Calibrate: This will trigger the calibration process for only these gloves.

Dongle: This shows the dongle linked to the user profile for wireless glove use. If more than one dongle is connected, you can select them from the drop-down menu.

Left and Right Gloves: This shows the gloves assigned to the user profile. This can be manually changed using the dropdown.

Hand offsets

alt text alt text

The hand offsets lets you tweak load and save the offset between the hand and the center of the tracker. The two position and rotation buttons will bring up a gizmo in the scene view to tweak the transformation in 3D space.

  • Translation The translation is the distance from the center of the tracker in centimeters. x to side, y is up and z is forward.
  • Rotation The rotation is the rotational offset in relation to the tracker in degrees.
  • Load from XML Allows you to load an XML file containing the offsets for easy re-use. MANUS Core comes with a array of presets for common tracker and glove device combinations.
  • Save to XML This saves the tracker offset to a location of your choosing.

Below is an example offset file. 

<?xml version="1.0" encoding="utf-8"?>
<TrackerOffset>
  <Translation>
    <X>6.5</X>
    <Y>3.75000024</Y>
    <Z>5.5</Z>
  </Translation>
  <Rotation>
    <X>-0.0007291227</X>
    <Y>270.000427</Y>
    <Z>89.99957</Z>
  </Rotation>
</TrackerOffset>

Calibration Profile

alt text

The Calibration Profile panel allows you to save, load, and adjust calibration data for Quantum and Metaglove series gloves. Calibration profiles define how raw sensor data is translated into accurate hand poses. Managing these profiles ensures consistent tracking quality across different sessions and devices.

You can use this feature both during live playback and after a recording has been completed. If you load a calibration file onto recorded data, the glove data is recalculated using the new calibration parameters. This is particularly useful if you later discover that your original calibration was inaccurate or inconsistent.

File Management

  • Load – Opens a file dialog to select and load a .mcal (Manus Calibration) file. Once loaded, the glove data updates immediately to reflect the chosen calibration.
  • Save – Opens a file dialog to save the current calibration as a .mcal file. Saving lets you reuse consistent calibration settings across different recording sessions or devices.

Manual Adjustment (Metaglove Pro series only)

For Metaglove Pro series gloves, you can also fine-tune the calibration by manually adjusting hand measurement values. These values are expressed in millimeters (mm) and correspond to specific anatomical dimensions of the hand. Adjustments can be made directly in the input fields provided.

  • Apply Changes – Confirms and applies any adjustments, recalibrating the profile using the new measurements.
  • Revert – Cancels your changes and restores the last applied calibration state.

Manual adjustments are helpful if:

  • The automated calibration process doesn’t capture the hand’s proportions at the required precision.
  • Small corrections are required after visually inspecting the hand in MANUS Core Dashboard.

For step-by-step instructions on how to measure and enter values correctly, refer to the Hand Measurement Guide.

Trackers

alt text

Here you can assign trackers to body parts. For absolute hand positioning a tracker needs to be added to each hand. For full body tracking all trackers except for the arm trackers are mandatory.

Calibrate: This will trigger the tracker calibration process.

Body Measurements

alt text

Here you can tweak the users' specific body measurements to better match their physical proportions. Make sure the viewport is set to Scene View to see the adjustments take effect. This only shows for full body setups.

Reset will reset all calibration values, meaning a new tracker calibration is needed.

Apply & Close

Applies any changes made and closes the profile settings.
