Body Tracking

info

This setting is not currently compatible with Concurrent Hands & Controllers.

Body tracking technology allows extended reality (XR) headsets to capture the movements of the participant's body. This feature is essential for understanding how participants interact with their virtual environment, what actions they perform, and how they respond to different stimuli. By tracking body movements, you can gain insights into human behaviour and decision-making.

Some headsets only use external cameras to get body tracking while others require additional trackers that must be attached to the participant's body. Check out this table to learn more about body tracking capabilities across different headsets.

note

If your headset does not support body tracking or if you want higher fidelity tracking, it is also possible to use the Sony Mocopi Integration.

Once body tracking is enabled, you will have two dropdowns appear to the right of the toggle. The first dropdown allows you to set the body tracking range.

• 'Upper':
  Captures the participant's upper body movements from the hips up, including all hand data points.


• 'Full':
  Captures the participant's full body, all upper body points in addition to the legs and feet. This works by using an AI pose estimation algorithm (Meta Generative Legs) that estimates the participant's lower body movements based solely on their upper body movements. It does not require any additional trackers or cameras! The lower body estimation is available on all Meta Quest devices.

The second dropdown allows you to set the body tracking fidelity.

• 'Low':
  Suitable for basic tracking needs.


• 'High':
  Provides high fidelity body tracking. This is the recommended option for body tracking. This is also required for utilizing Inside-Out Body Tracking (IOBT). Which is an advanced vision-based tracking system mapping upper body movements with greater precision (available exclusively on Meta Quest 3).
