What challenges arise when implementing full-body interactions using body tracking systems?

Example Concept: Full-body interaction systems must address the challenge of accurately tracking multiple joints and body segments in real-time, often using a combination of sensors like cameras, IMUs, and depth sensors. This involves complex data fusion and filtering techniques to reduce noise and latency, ensuring that the virtual representation of the user's body movements is both accurate and smooth. Additionally, developers must design intuitive interaction models that translate these movements into meaningful actions within the virtual environment.
