TaijiFlow AI - Silk Reeling Assistant

Empowering aging societies through biomechanically informed Taiji motion analysis

🌿 Inspiration & Aging Society

Global demographic shifts toward an aging society highlight the paramount importance of mobility, balance maintenance, and fall prevention to preserve independence and quality of life.

Extensive medical research supports Taijiquan for improving balance and proprioceptive awareness.
Chen-style Silk Reeling (Chan Si Jin) is a foundational discipline of continuous spiral motion.
Relies on harmonious coordination between weight shifting, waist rotation, and center-driven movement.
A nuanced somatic skill that is historically challenging to learn and verify during solo home practice.

🔍 Problem Significance

During solo practice using video recordings or online media, practitioners encounter three fundamental limitations that impact correctness and safety:

Abstract tacit knowledge that is difficult to translate into verifiable biomechanical execution without in-person adjustment.
Limited continuous access to qualified master coaching due to geographical, financial, and time constraints.
Complete lack of real-time kinematic feedback to detect subtle errors during practice execution.
Standard 2D videos cannot reveal 3D joint alignment discrepancies or offer personalized postural corrections.

🎯 Objectives & Solution

TaijiFlow AI translates ancient movement wisdom into computational representations, functioning as an intelligent biomechanical mirror for confident and safe practice:

Interdisciplinary framework bridging clinical biomechanics, computer vision, and martial arts wisdom.
Real-time movement quality assessment via standard webcams without requiring wearable sensors.

What is Silk Reeling (Chan Si Gong)?

Silk Reeling (Chan Si Gong) is the core of Chen Style Taijiquan. It fuses body, mind, and energy into one unified movement, like silk reeling from a cocoon:

Continuous: Smooth, connected, non-stop movement
Softness: Gentle, relaxed, but with hidden power
Spiral: Spiraling energy from feet through waist to hands

Key Principles

Correct movement requires Whole Body Connection:

Circular Motion: Move in arcs, avoid straight lines
Waist as Axis: Use the "Waist" as the driver
Upper-Lower Connect: Upper and lower body work in harmony
Internal Qi: Use "Mind" to lead "Qi"

Benefits

Consistent practice benefits both body and mind:

Coordination: Improve body coordination and connection
Balance & Structure: Enhance physical balance and structural stability
Mental: Reduce stress and focus via Moving Meditation
Energy Flow: Improve Qi flow, the heart of Silk Reeling

How does AI evaluate movements using a standard webcam?

The system uses MediaPipe Pose to extract 33 skeletal landmarks in real-time at 30–60 FPS, calculating kinematic correctness via our in-browser Heuristic Biomechanical Engine for joint angles, trajectory circularity, and waist initiation without expensive specialized hardware.

What do the 12 Biomechanical Rules evaluate?

It covers 9 single-hand rules (trajectory circularity, sunken elbow, waist initiation, vertical spine stability, smoothness, continuity, weight shift, upper-lower coordination) and 3 two-hand rules (bilateral symmetry, opposition & phase difference, and bimanual hand coordination).

Is webcam video recorded or sent to any server?

100% Safe (On-Device Edge Computing): All Computer Vision and pose estimation occurs purely inside your browser via WebGL/WebGPU. Raw video stream is never recorded, stored, or sent to any cloud server.

Can TaijiFlow AI replace qualified human masters?

Absolutely not, and never intended to: TaijiFlow AI is designed as an Intelligent Practice Companion—a biomechanical mirror for home practice to prevent bad postural habits between classes. Learning with qualified human masters remains indispensable for internal energy transmission and refined martial nuances.

What can the AI NOT evaluate? (System Limitations)

The system solely analyzes external body kinematics (joint angles, spatial trajectory, and waist rotation). It cannot measure internal Qi flow, listening energy (Ting Jin), or interactive push hands (Tui Shou). Moreover, it is not a medical diagnostic device; individuals with pre-existing conditions should consult a physician.

Who benefits most from TaijiFlow AI?

1) Solo Home Practitioners: lacking full-length mirrors who need immediate kinematic feedback, 2) Taiji Students: looking to reinforce proper posture between formal classes, and 3) Seniors & Wellness Seekers: aiming to enhance structural stability, prevent fall risks, and cultivate moving meditation.

How is kinematic data used, and how is personal privacy safeguarded?

Highest Privacy Standards: All webcam video is processed entirely inside your local browser (Edge-Native) and never transmitted or stored externally. Only anonymized kinematic coordinates are sent to academic databases if you voluntarily opt in as a research volunteer, strictly abiding by international research ethics and data protection standards.

Why is Body Calibration required before training?

Every practitioner has different height, shoulder width, and arm length. A quick 3-second T-Pose calibration scales the golden trajectory path and error thresholds to fit your individual body geometry perfectly.

Ideal Environment & Setup for Training

Use any modern desktop or laptop with a webcam. Stand 2–3 meters away with full body visible from head to ankles, maintain good lighting, and wear clothes that contrast with your background.

Safety & Medical Disclaimer

TaijiFlow AI is an interactive motion assistant and training tool, not a medical diagnosis device. If you have joint pain, injuries, or medical conditions, consult a physician before practice, and pause immediately if you experience dizziness or fatigue.
