Joint Angels Overview
Joint Angels is an innovative and accessible AI-powered tool designed for precise human motion analysis. Operating directly from your web browser, it utilizes computer vision technology to detect key body joints and measure their angles in real-time. This functionality is crucial for a wide range of applications, from medical rehabilitation to elite sports training. By simply using a webcam or uploading a video file, users can get objective, data-driven feedback on movement, posture, and form without the need for expensive equipment or specialized software. The tool is designed with simplicity and accuracy in mind, making advanced biomechanical analysis available to everyone.
How to use Joint Angels
Using Joint Angels is a straightforward process that requires no technical expertise. Follow these simple steps to start your analysis:
- Access the Tool: Navigate to the Joint Angels website using your preferred web browser.
- Choose Your Input Source: You will be presented with two options. Click 'Start Webcam' to begin a live analysis using your computer's camera. Alternatively, click 'Upload' to select and analyze a pre-recorded video or image file from your device.
- Real-Time Analysis: If using the webcam, the tool will immediately begin to detect your body's joints. A digital skeleton will be overlaid on your image, displaying the angles of your shoulders, elbows, wrists, hips, knees, and ankles in real-time.
- Utilize Features: You can use the 'Note-Taking Mode' to jot down observations during the analysis. The 'Confidence Threshold' slider allows you to adjust the sensitivity of the AI's joint detection for more accurate results. Use the 'Reset Joints' button if you need to recalibrate the detection.
- Review and Assess: Observe the angle measurements to assess range of motion, check for proper form during exercises, or analyze biomechanical efficiency.
