Important Disclosures for Users of Swing Catalyst Motion Capture Tool

Thank you for choosing our motion tracking solution for your golf swing analysis. To ensure you have the best experience and fully understand the capabilities and limitations of our tool, please carefully read the following important disclosures:

  1. Accuracy and Reliability
    • Limited Quantitative Testing: Our motion tracking system has undergone minimal quantitative testing. Therefore, the accuracy and reliability of the analysis may not meet professional standards for some applications. 
    • Pre-Trained Models: The tool utilizes pre-trained models (RTMPose and RTMDet) that are not specifically optimized for golf swing analysis. As a result, the motion tracking results may contain inaccuracies or inconsistencies, especially, for camera views not supported by the training data of the models. For more information on the pre-trained models see the following references:
      1.  RTMDet (Person detection): 2212.07784
      2. RTMPose (Persons’s body keypoints): 2303.07399, mmpose/projects/rtmpose at main · open-mmlab/mmpose · GitHub 
  2. Limitations of Pre-Trained Models
    • General-Purpose Training: The underlying models were trained on general datasets and may not capture the specific nuances and biomechanics of golf swings.
    • Pose Estimation Errors: Rapid movements and complex poses common in golf swings may under some circumstances lead to errors in pose estimation and motion tracking (see Environmental and Technical Constraints below).
  3. PC specifications (minimum):
  4. Environmental and Technical Constraints
    • Camera Quality: The effectiveness of the motion tracking is highly dependent on the quality of the video input. Low-resolution, shaky, or blurry videos can significantly reduce accuracy.
    • Lighting Conditions: Poor or uneven lighting can adversely affect the detection and tracking of motion and poses of the golf swing.
    • Camera Angles: The tool is optimized for frontal face-on and sagittal down-the-line camera views. Deviations from these angles may result in less accurate analysis. It is not recommended to use the top-down or back view of the golfer due to a high number of occluded body key points.
    • Occluded body points: Occluded body points are detected with less precision compared to visible body points. The user should interpret the position of occluded body points with caution.
    • Down-the-line view and DLP projector for launch monitors: Occasionally, DLP projector can affect performance of the motion capture models in down-the-line view. Sufficient lighting conditions is very important for these setups to prevent errors in the motion capture models.
    • 2D inference only: The Swing Catalyst Motion Capture Tool does only provide 2D inference in the selected camera view. Inter-session deviation of the camera setup may affect the comparison of results. Identical camera setup should be used when comparing golf swing trials. 
  5. User Responsibility
    • Professional Advice: This tool is intended for informational and recreational purposes only and should not replace professional coaching, instruction, or biomechanical analysis.
    • Verification of Results: Users should independently verify the accuracy of the analysis before making any changes to their swing or training regimen based on the tool's output.
  6. Privacy and Data Security
    • Data Processing: Videos and data processed by the tool may be stored for analysis purposes by your explicit consent
    • Data Storage and Deletion: We do not store your videos or personal data beyond the duration necessary for analysis unless explicitly agreed upon.
    • Third-Party Access: We do not share your data with third parties without your explicit consent.
    • User Consent: By using the tool, you consent to the processing of your data as outlined in our privacy policy.
  7. No Liability
    • Use at Your Own Risk: The use of this tool is at your own risk. We are not liable for any inaccuracies in the analysis or any decisions made based on the tool's output.
    • Limitation of Warranty: The tool is provided "as is" without any warranties, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose.
  8. Updates and Improvements
    • Ongoing Development: Our motion tracking tool is under continuous development. Features, functionalities, and performance may change over time without prior notice.
    • No Guaranteed Updates: While we strive to improve the tool, we do not guarantee regular updates or enhancements.
  9. Intellectual Property
    • Third-Party Models and Licenses: The tool incorporates RTMPose and RTMDet models, which are subject to their respective open-source licenses. Users must comply with these licenses when using the tool.
    • User Content Rights: You retain ownership of your video content. By using the tool, you grant us permission to process your content solely for the purpose of providing the analysis service.
  10. Appropriate Use
    • Personal Use and Commercial Use: 
    • Compliance with Laws: Users are responsible for ensuring that their use of the tool complies with all applicable local, state, national, and international laws and regulations.
  11. Technical Support and Contact Information
    • Assistance: If you encounter any issues or have questions about using the tool, please contact our support team.
