Frequently Asked Questions
Is it really free? Li Yuan was born from a passion for spreading Chen Style Taijiquan. It is a tool made available by Master Domenico Lento to help his students and practitioners of all levels improve their technical quality.
Do I need to download an app on my phone or PC? Absolutely not! Li Yuan is a Web-App. This means it works directly within your browser (like Chrome or Safari). Just click the link and you’re ready to practice, saving space and time.
Are you recording me while I practice? Your privacy is our priority. The Computer Vision algorithm processes video data locally on your device. Nothing is sent to our servers; no images are saved or recorded. You practice, the AI analyzes in real-time, and everything vanishes as soon as you close the page.
I’m not a tech expert, will I be able to use it? If you know how to open a webpage, you know how to use Li Yuan. The desktop interface is “Touchless”: once in front of the camera, you don’t even need to touch the screen. Just raise a hand, select the exercise, and the training begins. It’s simpler than a remote control!
Can it replace my Taiji Master? No. Li Yuan is your “assistant.” It is perfect for when you train alone at home and have no one to correct your circle trajectories. It helps you avoid forming bad habits between lessons with your Master.
Why does the mobile version seem less “precise” than the desktop one? Smartphones have less processing power than computers. We used a “Light” algorithm specifically for mobile devices to ensure fluid movement even at the park, sacrificing a bit of millimetric precision to give you a lag-free experience.
Which is the best browser for a perfect experience? For top performance, we strongly recommend Google Chrome (or Safari on iOS). It is the browser that best handles the Computer Vision libraries we utilized.
