Real-time postural analysis
For several months, I have been working on a computational analysis project focused on violin technique, using the latest artificial intelligence tools. As many of you may already know, I have spent years researching this field using pre-AI tools such as Kinovea and Excel to detect, measure, and evaluate movements. Today, it is possible to perform these analyses in real time with minimal equipment.
My current goal is to develop a kind of virtual teacher capable of analyzing technical data and providing real-time feedback. The parameters I am considering include body position, joint angles, movement speed, and comprehensive biomechanics, with automated analysis tailored to each violinist.
At this stage, I am developing several analysis modules covering general posture, vibrato (both technical execution and sound production), left-hand technique, and bowing technique.
The measurement of these parameters is almost complete. The next step is to turn all this information into a practical teaching tool. To achieve this, I plan to develop a structured course consisting of dozens of lessons, each designed to address specific technical objectives.
By analyzing these data collectively, it will be possible to investigate correlations between individual biomechanical characteristics and instrumental performance. The ultimate goal is to identify the most appropriate technical approaches for each biomechanical profile, moving towards a more individualized approach to violin teaching grounded in objective data.
Below, I share a brief demonstration of real-time postural analysis using the mobile app, combining correct and incorrect technique to demonstrate the detection of postural issues, including incorrect shoulder positioning, improper wrist alignment, and excessive finger extension and flexion in both hands. I also include a recording of a general technical analysis conducted with one of my students. The images show several boxes displaying information about left-hand technique, right-hand technique, and overall body posture. Blue indicates excessive joint extension, while red indicates excessive flexion. The reference ranges and their interrelationships are based on my biomechanical research and established anatomical benchmarks for healthier movement.
